How to properly cover the roof of the house with your own hands? Overlapping the roof of the house Overlapping the roof in a private house

The roof is one of the main elements of any structure. It performs an important function - it retains heat during indoor areas protects them from overheating.

The quality of the materials from which this structure is constructed depends on how completely and efficiently the building will be protected from melt water and precipitation.

Assignment of materials for roofing

When building a house, you will need to select roof covering materials for several elements, among which:

1. truss system (photo 1). To complete this element pitched roofs you will need bars or boards made of wood.

2. crate (photo 2) - a structure laid on rafters and taking the main load of the roof. For its construction, bars, boards made of wood, preferably coniferous, OSB, moisture-resistant plywood are used.

3. Control grille (photo 2), equipped to form a ventilation gap. Made from wood. Air circulation is carried out by a simple draft method or using special valves. In construction, sometimes instead of wooden beam a metal profile is used under the rafters, grating, crate and counter-crate (photo 3).

4. Thermal insulation layer , which is laid on the crate during the arrangement warm attics, attic. When choosing a heater for overlapping, it is worth paying attention to its resistance to moisture, sensitivity to temperature fluctuations, the ability to highlight unpleasant odors. Usually, mineral wool, fiberglass-based products are used for overlapping.

5. Vapor barrier film , covering the insulation from the inside from the ingress of wet vapors from the premises of the house, preventing the formation of condensate.

6. Waterproofing (photo 4), preventing moisture from entering the insulation from the outside. There are a lot of waterproofing for overlapping: films, coating, sprayed and other types. The choice of the right one depends on the type and shape of the roof, insulation, features of materials.

7. Fasteners (photo 5). Fasten the elements with fasteners designed for a particular type of material.

Overlapping is recognized as the simplest cold roof. For him, you do not need to equip the roofing "pie". You only need wood for the construction of rafters, battens, roofing material.

What is the roof made of?

The roof should be installed immediately after the “pie” is assembled, otherwise it may be damaged by wind and precipitation. There are roofing materials on the market different types, differing in technical specifications and prices.

metal tile

It is a thin sheet of galvanized steel, stylized as a classic tile due to profiling (photo 3, 4). It has attractive aesthetic properties obtained by coating the sheets with a decorative and protective layer of polymers. Differs in special ease. The properties depend on the characteristics of the steel, the type and class of coatings.

Slate

Durable durable material. It is distinguished by incombustibility, low cost relative to other types, good electrical insulating qualities. Easily processed, not subject to corrosion at all, low noise during the period of precipitation.

Decking is inexpensive

Steel profiled sheets have ridges of different heights and widths of wavy, trapezoidal, and other shapes. They have a protective coating in the form of layers of zinc and colored polymers. Differ simple installation(photo 6), resistance to corrosion with intact protective coating, low weight. The disadvantage is the increase in sound when it rains. The construction of a roofing "pie" helps to solve this problem.

Ceramic tiles are prestigious

Made from fusible clay, it lasts a long time, while its color only becomes more saturated. It is not sensitive to precipitation, frost, sun rays, fire, has good soundproofing properties, low thermal conductivity. The disadvantages can be considered high prices, fragility, heavy weight.

Any building material, including roofing, is not eternal and has a certain service life, after which the owner of the building is faced with the need for a new roof covering. Roofing material has a fairly long service life, and is likely to installation times of the previous roof, a significant number of decades have passed, during which the market building materials enriched considerably.

In the article, we will analyze how to cover the roof of a private house with our own hands and how much it will cost.

The choice of roofing

First of all, you need to decide: how to cover the roof of a private house? At the moment, there are many different roofing coverings with different characteristics. Let's consider the main ones:

Remember that the right roofing material is half the battle in roofing.

Definition required amount roofing material depends on the area of ​​\u200b\u200bthe roof, which is easy to calculate on your own. It is important to add 10-15% to the resulting number of square meters due to overlapping roofing and up to 25% if the roof has a complex shape and will require frequent cutting of the material.

Overlay preparation

In addition to the roofing material itself, you will also need a construction tool and preparation of the entire truss system for laying a new coating. Associated costs can reach up to 50-100% of the required cost of roofing materials.

So, regardless of the chosen roof, you will need:

• Hammer, tools for cutting roofing material, drill and screwdriver for fixing the roof;
• Fasteners if they are not included with the roofing material;
• Roulette, level and pencil for measurements;
• Materials for creating a frame for the selected roof.

Before covering the roof, it is necessary to critically inspect the condition of the entire truss system in order to search for rot, mold and fungus. If you decide to change the roofing due to constant leaks, then the listed troubles will find themselves in many places. Laying a new roof on a damaged truss system does not make sense - it is a waste of time and money. You will probably have to completely or partially replace the affected wooden elements, change insulation and insulating materials.

If the inspection showed that the truss system is in order and you only need to update the roof finish, you still need to carry out the crate for the selected material:

• Under the flexible tile, a continuous crate system is created from moisture resistant plywood or calibrated beams;
• For other types of roofing, it is required to fill the lathing with slats in increments of 35-50 cm, depending on the material and the angle of the roof.

The procedure for performing roofing work

The success of the planned renovation of the roof depends on the knowledge of how to properly cover the roof. Recall the basic procedure for overlapping the roof with your own hands:

• Do not forget about the weather conditions: it is good if the weather is calm and calm. Some materials (like flexible tile or ondulin) require additional special temperature regime. In no case should you cover the roof in the wind or rain - it is dangerous to health and life!
• First of all, the rafters are installed (or checked) - they must be made of dry wood without knots and cracks;
• Further, a heater is laid between the rafter legs from the inside, and a layer on top waterproofing material. Laying roll materials always made with an overlap of 10-15 cm of all joints;
• Stuffing the crate is made according to the requirements of the selected roofing material. General rule- observance of one level and the creation of an even flooring for the future roof;
• Laying roofing is made from the lower slope to the ridge with the obligatory determination of the level and evenness of each element. Particular attention is required to such elements as the valley, the adjoining of the roof to pipes or ventilation shafts;
• The final event is the installation of the roof ridge. Its installation is carried out according to the rules defined for each roofing material.

Budgeting

In conclusion, consider how much it costs to cover the roof in a private house. As we found out earlier, the largest amount of funds will be required to purchase the roofing material itself. Knowing the area of ​​\u200b\u200bthe roof, it is easy to calculate how much it will cost to purchase it, taking into account the margin for joints and other possible cases.

When planning expenses, it is important to take into account the condition of the entire truss system: if it requires repair or complete replacement, then the costs will increase at least 2-3 times. However, these are necessary and necessary expenses, since the operational life of the roof directly depends on the quality of the truss system.

A possible point in the expenditure map being drawn up will be the involvement of hired forces, if you cannot rely on your own forces alone. The cost of the services of hired builders is quite high, and therefore one of the main opportunities to save on roofing is to do all the work yourself.

Roof covering is a laborious and rather costly process, which often does not come down to just replacing the roofing. When planning this process, it is important to seriously assess the condition of the truss system and calculate in advance all the costs of building a new roof.

The article analyzes in detail the composition of the "roofing pie" of the roof, provides a rationale for the need for each layer and describes some of the nuances. After reading, you will confidently navigate the issue of prices for roofing and will be able to calmly discuss with a construction company the roofing of a private house.

What is the roof made of?

The roof is an extensible concept, since it is usually understood as a coating, which consists of a “roofing pie” and racks connecting load-bearing walls with a coating (Mauerlat, rafters, racks). But if we talk about how to properly cover the roof of a private house, then attention should be focused on the roofing pie and the crate.

Before overlapping, the coating material is selected. It is from this choice that the necessary parameters of the crate, the method of laying and, of course, the total budget of the project will depend.

Roofing cake consists of:

battens. The crate distributes the pressure of the coating on the rafters. Depending on the coating material, a discharged or continuous crate is arranged. A solid crate provides for a distance between the slats of less than 1 cm. A solid crate is usually arranged in two layers: first, the slats are stuffed onto the rafters, and then the plywood. This type of crate is necessary for soft tiles, metal tiles and flat slate. A plywood layer with such a cake device acts as an additional moisture and sound insulation. But for corrugated sheets of steel or slate coating, cement-sand and clay tiles, a discharged crate is used.

In the grooves of the crate or between the rafters fit insulation. Usually it is mineral wool. Insulation is needed to save energy for heating in winter period. Almost a quarter of the heat "flies away" through the roof, because warm air always rises.

The insulation is covered waterproofing designed to prevent condensation of moisture from the outside air in the insulation layer. Not all moisture is retained by the coating, so waterproofing will keep the insulation for a long time.

Placed on top of the insulation counter-batten. It separates the coating and insulation, creating an air gap as an additional warming layer. In addition, due to the additional air layer, micro-ventilation of the waterproofing surface occurs.

Fits on the counter-batten coating, which can be of different shapes and sizes, everything here depends only on the preferences of the customer.

Often, it is better to provide additional steam protection from the inside of the heater. Condensation may form in the attic, especially if there are engineering Communication. The ingress of moisture on the insulation will significantly reduce the heat-insulating properties.

Floor material options

Roofing options modern market building materials provides a huge amount. Let's start with the most familiar and traditional, discuss the advantages and disadvantages, and then provide information on exotic coating options. In the end, we will draw a conclusion about the cost of material and work, bringing all the information into a table.

Slate

Slate is a traditional, proven tool that is still one of the most popular flooring options. Slate is cheap, of sufficient quality and time-tested. The main disadvantage is the weight and fragility of the material, which require updating or replacing the crate.

With special care you need to approach the fastening of the slate. Firstly, the direction of laying sheets depends on the direction of the wind. The overlap must be turned to the leeward side, otherwise the sheets may be pulled out by gusty winds.

Nails are selected with a mandatory rubber gasket.

Decking

Metal sheets with various colors of anti-corrosion coating. Particular attention should be paid to avoid scratches. Damage to the anti-corrosion coating significantly reduces the service life of the material.

metal tile

It is a popular and easy to handle material. A variety of palettes will allow you to decorate the most boring design. The material is laid from the bottom up. Also, do not forget about soundproofing.

On our website you can find the most . In the filters, you can set the desired direction, the presence of gas, water, electricity and other communications.

Soft tiles

Perhaps the easiest material to install, under which, nevertheless, a continuous crate is required and good waterproofing. When calculating the budget, these factors should be taken into account. The material has only one drawback: it can only be laid at positive temperatures.

Clay tile

Clay tile is fragile and heavy, but durable material. Such a coating is used longer than slate, but it is quite difficult to mount it, and therefore expensive. Is it worth it - everyone decides for himself.

Cost of work

Let's calculate the approximate cost of roofing work. Our calculation will include materials, alteration of the crate, hydro and vapor barrier, roof insulation and installation of the coating, as well as the installation of a ridge. The calculation will be carried out at average prices for a square house measuring 10x10 meters. The gable roof of such a house will have an area of ​​\u200b\u200bone slope of 60 square meters, respectively, the total coverage area of ​​\u200b\u200b120 squares at an angle of inclination of 35 degrees.

The first step is dismantling of the old coating and crates. Average price tag in Russia: 250 rubles. per square. This means that for our standard house it will cost 30 thousand rubles.

The next step is installation of insulation boards. The cost of the material is on average 2000 rubles per square meter, plus installation will cost 100 rubles per square. It turns out 252 thousand rubles

Installation of waterproofing. The price of the material is on average 150 rubles per square, plus the work will cost 80 rubles. Total 27600

It will cost about the same price as the crate. Those. 30 thousand rubles.

On our website you can find contacts construction companies who offer services roof design and repair. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

metal tile will cost 400 rubles per square meter, plus 300 rubles. it is worth blocking sq.m. roofs. So 84000 will cost installation.

Installation of the skate. The average cost of a 2-meter section of a ridge for a metal tile is 450 rubles. Installation will cost about 150 rubles for running meter. Total: 3750

In total it turned out 427 thousand. But you need to take into account unforeseen expenses, and therefore we will round the amount received to 450 thousand rubles. It goes without saying that this is a very average value, it all depends on the cost of building materials and construction work in a particular region. But in any case, such a calculation can show you how much money it will take to cover the roof of a private house.

Here is a small table of coating materials with average prices for the fall of 2018.

The calculations also need to take into account the cost of the crate, which may vary depending on the method of sheathing, the cost of repairing the truss system and repairing the ventilation shaft and risers.

exotic roof

Exotic roofs are significantly more expensive, both in terms of building materials and installation. An exotic roof refers to a reed or garden roof.

Reeds are exotic, but at the same time practical. This material does not require waterproofing and vapor barrier. Large thickness guarantees good noise protection. At the same time, the reed does not burn due to the special impregnation of the material, rodents will not start in it, it will not drip or rot. Firms-manufacturers of euro-cane give a guarantee for 50 years.

On the other hand, reeds are very expensive. A sheaf of eurocane costs about 200 rubles, but there are 4-5 sheaves per square meter, and the roof is often covered in two layers. In this case, the overlap of the roof will cost an average of 2000-2500 rubles per square meter.

The rooftop garden is another trend that has come to us from Europe. The garden is beautiful, it will save heat well, due to the layer of earth, but at the same time it can leak when incorrect installation. Gardens can be extensive and intensive. The first is a kind of "lawn on the roof." Undersized and unpretentious plants are planted on 20 cm of soil. But an intensive garden is a roof with a large amount of soil and real trees.

The garden will cost you 10 thousand rubles. per square meter, not counting the cost of creating an ecosystem. At the same time, the repair and dismantling of such a roof is associated with a large number of problems. It is almost impossible to repair such a roof without destroying the garden, and for dismantling it will be necessary to literally “rip off” the entire roof to the rafters, which can easily become unusable from leaks. Roofing a house on such a garden will be many times more expensive than with ordinary material, but the view in this case will be much more aesthetic.

Conclusion

The modern market is ready to offer you a variety of roofing materials: from ordinary slate and metal tiles to various soft coatings and exotic options. You need to choose according to the appearance of the building, your own wishes and budget. In any case, when choosing what material to cover the roof with, it is better to make a preliminary cost calculation in order to know what to focus on in negotiations.

When planning the construction of a house, special attention is paid to the choice of roofing. I want it to be of high quality, durable and affordable. Worth paying attention to. A variety of roofing materials can confuse anyone. In such situations, a thorough analysis of the advantages and disadvantages of each type of roofing material related to the economy class will help to make a choice. About how much it costs to cover the roof in a country house or in a private house and what material is best to do this, we will burn in this article.

Metal tile - the main material

When the question arises of how to cover the roof of a private house, the answer is most often a metal tile. This material has received its wide distribution due to its clear advantages.

Advantages of a metal tile:

• availability, both in terms of price and availability of material in stores;
• simplicity and ease of installation;
• environmental friendliness - due to the fact that the metal tile is made of steel;
• long term service - more than 20 years;
• large selection of colors.

The disadvantages of this roofing material are:

• noisiness - during the rain, the sounds of drops hitting the roof will be clearly audible;
• windage;
• the need to additionally perform insulation and soundproofing of the roof;
• susceptibility to corrosion;
• a large residue of waste when roofing complex roofs;
• a minimum of rental drawings.

When choosing a metal tile, you need to calculate not only how much it costs to cover the roof in a private house based on the cost of material and roofing per square meter, but also the price of additional elements. It often happens that metal tiles are sold at a discounted price, and then, when it comes to buying additional elements, they turn out to be prohibitively expensive.

The thickness of the steel and the amount of zinc contained - important indicators quality of metal tiles. The higher these figures, the better. Buying metal tiles from trusted manufacturers, you can protect yourself from unnecessary hassle with poor-quality material.

The cost of a metal roof depends on many factors:

• material cost ($6-13 per sq.m.);
• the cost of installation work (amounts to 50-100% of the cost of the material);
• the cost of additional work and materials;
• design complexity.

The roof area does not depend much on the square of the house, since the building can be two- or three-story, which means that the size of the roof will depend only on the floor area and its own design features.

For more accurate cost calculation, you should use our calculator, or roof.

On average, a metal roof will cost:

• for a small house (about 100 sq. m.) - close to $ 1000;
• for a medium-sized house (about 200 sq. m.) - $ 1200-2000;
• For big house(about 300 sq. m.) - $ 2000-3000.

Soft tiles for the roof of the house

Soft tiles are often chosen for complex construction roofs.

The main advantages of this material include:

• ease of installation;
• a huge variety of colors of the material;
• minimum waste during installation;
• environmental friendliness;
• noiselessness;
• durability (more than 30 years of operation);
• minimization of risks when buying, due to the complexity of manufacturing the material and the impossibility of forging it.

The disadvantages of soft tiles are:

• frequent material breakage due to strong wind;
• the need to perform a solid base - a common crate;
• the impossibility of building a "residential" roof.

The price of soft tiles

Considering that the cost of soft tiles is $7-17 per sq.m., and roofing work will cost $6-40 per sq.m., for a roof made of soft tiles you will need:

• for a small house (about 100 sq. m.) - $ 1000-4000;
• for a medium-sized house (about 200 sq. m.) - $ 1200-8000;
• for a large house (about 300 sq. m.) - $ 1800-12000.

This material also requires a careful approach to the selection of additional elements and the assessment of their cost.

Wavy bitumen sheets

On corrugated bituminous sheets, people who erect buildings for household purposes or simple summer houses most often stop their choice.

Among the advantages of this material are highlighted:

• low cost;
• ease of installation - the roof can be performed even without special skills;
• ease of transportation;
• noiselessness;
• the possibility of using lightweight inexpensive crates;
• unusual shades of material;
• environmental friendliness;
• long service life (at least 15 years);
• low cost of additional elements;
• market transparency - no risk of buying a fake.

Disadvantages of corrugated bitumen sheets:

• limited design solutions;
• the possibility of leaks;
• the possibility of sagging material.

The use of special nails with specific caps (20 nails per sheet) during the installation of this material will extend the life of the roof.

Cost of corrugated bitumen sheets

The cost of the material ranges from $ 9-12 per sheet, roofing with bitumen sheets costs $ 4-5. Fully roofing from corrugated bitumen sheets will approximately cost:

• for a small house (about 100 sq. m.) - $ 800;
• for a medium-sized house (about 200 sq. m.) - $ 1000;
• for a large house (about 300 sq. m.) - $ 1200.

Keramoplast

Keramoplast is a composite material created from organic raw materials and plastic granules.

The main advantages of keramoplast:

• high rigidity;
• noiselessness;
• absolute environmental friendliness.

Among the disadvantages of keramoplast, it is especially often manifested:

• poor tolerance for temperature changes;
• fragility;
• complexity of transportation.

• for a small house (about 100 sq. m.) - $ 800-1200;
• for a medium-sized house (about 200 sq. m.) - $ 1200-6000;
• for a large house (about 300 sq. m.) - $ 1500-8000.

Composite metal tile

Composite metal tile acts as a little-used material, since few people know about its existence. Its basis is a metal sheet, and the surface is made of stone granulate.

Among the advantages of this material are noted:

• a wide selection of colors and shapes of colors;
• high anti-corrosion ability;
• noiselessness;
• durability (more than 50 years of service);
• reliability.

Besides this roofing material includes all advantages of a metal tile and a soft roof.

The downside is:

• complexity of installation;
• relatively high cost of material and additional components.

The cost of such a roof is in the following price range:

• for a small house (about 100 sq. m.) - $ 7,000-20,000;
• for a medium-sized house (about 200 sq. m.) - $ 20,000-50,000;
• for a large house (about 300 sq. m.) - $ 40,000-60,000.

The analysis of the given data shows that a roof made of corrugated bituminous coatings will cost the least, but this material also has the shortest service life, while the most expensive material - composite metal tiles - has the greatest durability among all materials and the fewest shortcomings.

How much does a roof cost: reviews from the forum

Igor M.

Gathered to reconstruct the cottage. My house is not big, only 6×9. Want old roof dismantle, raise a floor by a meter and install a new one from metal tiles. The roof is the simplest gable. I started asking prices. On a turnkey basis, they gave me a price of 450 UAH per m2. It's just a job without materials.

I am disappointed. It is only necessary to pay 130 UAH per m2 for the metal tile itself, and plus the rafter part, insulation, etc. It's getting expensive. But I began to ask further, they said that the maximum price is now 200 UAH per m2. I spoke with the foreman. He promised to do it for 300 m2. We calculated the materials, it turned out with the work 48,000 UAH, about $ 2,000 We agreed that we would start with the first rays of the spring sun. I put money aside, I'm waiting.

Sergey B.

I undertook to remake my parents' house a little. I did the insulation. I decided to cover the roof with metal tiles. I don't need to do anything special. me two years ago overhaul did the roof, just remove the slate and replace it with a metal tile.

I did not think for a long time, I phoned the specialists who had already worked for me. They say 300 rubles ($5) per square, and we will change everything. Indeed, he brought the materials, the guys came, they did everything qualitatively. In Moscow, I would hardly have invested in such a budget, except that in Ukraine their construction services are cheaper.

Alexey K.
I live in Russia, I am from Ukraine. It so happened that in two years I had to change the roof on the houses in two different countries. First with the wife's parents, and then with their own. And you know me, confused by some price points. When I was engaged in replacing the roof on my mother-in-law's house, everything was for the first time. I thought for a long time what material to choose and how to make it. Although I am a busy person, it was still interesting. How do people make and from what. Therefore, he delved into the cost of materials and the quality of work.

The following year, he came to visit his parents. I looked at the old house and decided that it needed to be updated. I didn't have any issues with the roof. I knew exactly what and how I needed. In both cases, this is a house, approximately 200 m2, under a slate gable roof with attic. Having experience, I immediately began to look for a contractor who would do all the work on a turnkey basis.

I'm still on vacation, so I left control. I was lucky with the builders and for the first and second time I came across experts in their field who can do the job well and quickly. The roof went up very quickly. But being involuntarily engaged in construction, or rather curatorship, he compiled the so-called international price list of roofing works. We will not take materials, they are almost similar, in dollar terms.

Turnkey roof manufacturing

So straight to the point:
1. Dismantling of the old roof - 250 rubles / m2; or 10 UAH/m2.
2. Manufacturing cold roof turnkey from metal tiles, depending on the complexity with the installation of rafters, installation of battens, waterproofing, fastening of counter rails, directly to the metal tiles themselves, skates, wind slats, valleys - 1200 - 1300 rubles / m2; or 130 - 160 UAH / m2.
3. Warming - 280 rubles / m2; or 40 UAH/m2.
4. Installation of floor beams - 150 - 200 rubles / linear meter; or 35 UAH/lin.m.
5. Installation of drains, depending on the floor - 245 - 420 rubles / linear meter; or 40-55 UAH / running meter
6. Sheathing overhangs - 550 - 600 rubles / linear meter; or 70-90 UAH/rm
7. Arrangement of gables with materials for the facade, for example, siding or clapboard - 350 - 400 rubles / m2; or 60 - 70 UAH / m2.
8. Installation of a roof window - 3000 - 4000 rubles / piece; or 600 - 1150 UAH / piece.
9. Installation of draft walls and ceiling - 70 - 80 rubles / m2; or 35 UAH/m2.

Measurements in both cases were carried out free of charge, because subsequently, I took both the material and ordered the work itself. Although initially everyone said that the service was paid. The metal tile and related materials were delivered free of charge, for the same reason.
After analyzing the metal roof, I decided to look at the roof from different materials. List prices for installation work cold roof when installed on a turnkey basis:
Bituminous tiles - 1800 - 2100 rubles / m2; or 160 - 220 UAH / m2.
Natural tiles - 1100 - 2000 rubles / m2; or 300 - 350 UAH / m2.
Roofing corrugated board - 800 - 1000 rubles / m2; or 150 - 200 UAH / m2.
Composite tiles - 1100 - 2000 rubles / m2; or 200 - 250 UAH / m2.
Euroslate, Ondulin, Aqualine - 800 - 1000 rubles / m2; or 150 - 200 UAH / m2.
Tariffs for insulation, installation drainage system and other works do not differ from those used in the construction of a roof made of metal.

Thus, we can conclude that the choice of roofing material directly depends on individual preferences, phrases, purpose and design features of the building, so it is impossible to give an unambiguous answer to the question of what is better and cheaper to cover the roof. Each material has its pros and cons, so you need to make an individual choice, based on the above data.

   Guys, by and large, what's the point in asking in the comments how much work on your roof will cost? Ask a question either to several contractors at once and compare, or if you make an estimate, you can contact the supplier directly. Serious companies will calculate everything for you for free, at the same time you will communicate with the manager more, maybe you will also get a discount for yourself. I took a metal tile in the Grandline for my double slope (gazebo + canopy). Everything was calculated, brought, neatly packaged, the third year I do not know the troubles. Who needs it, site grandline.ru

   how much does it cost to cover a metal roof soft roof– 183 sq.m.

5. George

   If you can calculate the approximate cost of work with your materials:
   1. Remove the galvanized iron roof statue.
   2. Insulate with 150 mm basalt (or other material) slabs. with hydro and vapor barrier.
   3. Cover the roof with metal tiles.
   4. Insulate the pediments over the lining (offer an option for insulation).
   The roof is gable, area 120 sq. m.. Gables of 18 square meters. m. With Windows Of 1.8 Sq. m.
   I can send a drawing of the roof and gables to your E-mail.
   Best regards, Georgiy.

Each of us has seen a metal tile more than once. Every year, more than one hundred square meters of this roofing material is mounted on various roofs. In view of the widespread use of metal tiles, I would like to say a few words about the correct choice of material, its proper storage, as well as how to cover the roof with metal tiles and install all the additional elements that come with it.

Advantages of metal tiles

For the first time this roofing material appeared on sale in Finland in the second half of the last century and since then it has been successfully leading among all coatings of this kind. Today, metal tiles are made from aluzinc steel, which has a protective polymer coating that protects the metal from corrosion and is painted in different colors.

In the manufacture of this material, several coatings are used, which differ in their properties, cost and thickness. Galvanized profiled sheets have a more complex internal structure than it initially seems: usually a cold-rolled hot-dip galvanized sheet is used for the base, which has a thickness of 0.4-0.5 millimeters.

The metal tile has a list key qualities which determined its popularity: light weight, ease of installation, long useful life, increased wear resistance and reasonable price. The material does not burn, deform or melt. Sometimes consumers sin for increased noise during strong winds or rain, but this is observed when the roof, sound insulation and drainage are not properly installed.

This roofing material has a stylish appearance, often imitating the traditional ceramic tiles, but far surpassed the clay analogue in terms of ergonomic qualities. Use a metal tile for carrying out reconstruction of buildings or new construction. In any case, it is able to serve 50 years, or even more, without losing its original appearance during the entire period of operation.

The process of laying sheets of metal tiles refers to such work, during which it is necessary to strictly adhere to the requirements specified by the manufacturer in the instructions. Deviation from these recommendations can lead to a significant reduction in the service life of the material, and manufacturers in such cases refuse liability due to breach of warranty.

Calculation of sheets of metal

To buy the right number of sheets of metal tiles, first pay attention to any residential building in which such a roof is equipped. “Waves” are placed across the roof slope, and “rows” are located along the roof slope. The step of a metal tile is the distance between the rows. And the sheet, which consists of 6 "waves" and has a step of 350 millimeters, is called a "module". One-, three-, six- and ten-module stock sheets are on sale.

But you can also order sheets according to your own measured sizes. Of course, the prices for special orders will be higher. However, when covering a complex roof with sheets standard sizes a lot of waste is obtained, which also affects the price of covering the roof with metal tiles. But the possibility of individual cutting of roofing material for each customer allows you to reduce this waste much. Therefore, you need to choose warehouse sheets or cut them based on a specific option.

The metal tile sheet has 2 widths: general and useful. As for the length of the sheets produced, the minimum length is 450 millimeters, and the maximum reaches 7 meters. The lower 50 millimeters of the sheet from the cut line to the crest of the wave is called the "lower cut", the size of which is the same for cut and stock sheets. The "top cut" from the wave crest to the top edge is 50 millimeters for standard sheets metal tiles and up to 300 millimeters for sheets on special order.

To calculate the number of rows of sheets horizontally, you need to divide the maximum length of the slope along the ridge or cornice by the useful width of the sheet. Round the resulting number up. You can calculate the length of the sheets in the stacked row by summing up several values.

The first of them is the length of the slope, measured from the eaves to the ridge, that is, from the bottom to the top of the slope. The second is the length of the cornice overhang of 0.05 meters, which is calculated to prevent moisture from entering under the roofing sheets. The third is the length of the vertical overlap of sheets of 0.15 meters. If there are two or more sheets in a row, then each subsequent sheet will be superimposed on the bottom one, interlocking with each other in the place of the “lock” and forming a strong, tight and even connection.

When choosing sheets of metal tiles, remember that it is not recommended to take sheets that have a length of more than 4-4.5 meters, because it is costly and rather laborious, inconvenience arises when loading, unloading and lifting material onto the roof, because a long sheet can be scratched, bent and deform. When using very long sheets of metal tiles, it is better to cut them into pieces that need to be laid with an overlap of 150 millimeters.

Metal tiles, according to building codes, should be stored in an unheated room where protection from weather factors - rain and direct sunlight is maintained. Profiles that have factory packaging must be laid on a flat area using bars as a stand, which have a thickness of 20 centimeters, in increments of 50 centimeters. If you plan to store the material for longer than 1 month, unpack the metal tile and stack it in stacks up to 70 centimeters high.

The construction of the truss system

The calculation of the elements of the truss system must be carried out at the design stage of the roof. It is necessary to take into account the features of the shape of the roof, wind and snow loads for the region. With errors in the calculation of the pitch and cross section of the rafters, the roof may sag over time, and cracks also appear. The step of the rafters under the metal tile should be 600-900 millimeters. If this indicator is increased, then it is recommended to use cross-section boards of large section (crate). As a rule, it is customary to use rafters with a section of 100 or 150 by 50 millimeters.

If you plan to insulate the roof, it is advisable to equip additional horizontal ventilation between the rafters. Namely, in the side part of the rafters, drill holes near the upper part of the roof that have a diameter of 2-2.5 centimeters, in increments of 30 centimeters. After that, it is necessary to treat wood materials with fire-fighting and antiseptic impregnations.

Before you cover the roof with a metal tile with your own hands, it is recommended to check the length of all slopes diagonally, since the roof must have a regular rectangular shape. Then check the eaves, ridge, plane and slope fractures for horizontality. In the presence of errors, it is necessary to level the surface.

When choosing a metal tile as a roofing minimum angle the slope of the roof should reach 14 degrees, which ensures an acceptable flow of water, the roof itself will not accumulate moisture and leak in the future. Be sure to fit the eaves board into the slots cut into the rafter legs to add more rigidity to the gutter hooks.

In many instructions for installing sheets of metal, it is also recommended to install a frontal bar. The frontal board is attached to the end of the rafters for additional protection. Sheathing of eaves overhangs is performed using corrugated board, siding or spotlights, having previously made a special crate. If non-perforated soffits are used as a backing, ventilation gaps must be left to ensure free air flow into the space under the roof.

Hooks for gutters are installed directly in front of the fastening of the metal tile. It is best to use long hooks that provide greater structural strength. Mount the gutter holders on the cornice strip, sawing out the grooves for the "leg" of the hook. Fasten the hooks with self-tapping screws. The pitch of the gutter holders usually matches the pitch of the rafters. For a mounted roof made of metal, it is customary to use short hooks.

Arrangement of waterproofing and ventilation

Anyone roofing cake moisture is contraindicated and its minimal ingress into the under-roof space, as it leads to rotting and cracking of the truss system and corrosion of metal sheets. It will be possible to avoid such negative factors if you choose a heater of sufficient thickness for the roof, protect it from the effects of condensate through a waterproofing film and from moisture through a vapor barrier, and also arrange natural ventilation space.

To organize proper ventilation of a roof made of metal tiles, it is necessary to calculate the area of ​​ventilation gaps, according to the ratio of the total space of gaps for ventilation to the total area of ​​the roof 1 to 100. Remember that ventilation gaps must be placed between the waterproofing and the roof, heat and waterproofing for through air flow, ridge and in the filing of the eaves for air flow.

For waterproofing roofs made of metal, it is customary to use waterproofing and anti-condensation films, as well as superdiffusion membranes. Categorically it is not necessary to lay bituminous waterproofing under a metal-tiled roof! The waterproofing material is laid in such a way that air flows from the eaves without obstacles under the roof ridge and out through the ventilation holes that are installed in the highest place.

A waterproofing layer is laid in a horizontal direction between the ridge and the eaves with an overlap of 15 centimeters, on top of the truss system. You should start from the cornices. Lay the material with a slight sag between the legs of the rafters of 20-25 millimeters to avoid tearing the film in the cold season. Fasteners of this material can be carried out using wooden slats installed along roof trusses. Vapor barrier film overlap under the insulation, connecting its pieces with adhesive tape.

The construction of the crate under the metal tile

The metal tile requires the creation of a crate. For this, bars are used that have a cross section of 5 by 5 centimeters, and boards measuring 3.2 by 10 centimeters. First of all, nail falling bars from the ridge to the eaves to the rafters along the waterproofing film. Lathing boards are attached to them in the horizontal direction. The first of them from the eaves should be 1-1.5 centimeters thicker than the rest - 5 by 10 centimeters.

The boards must be fastened in compliance with such distances: from the beginning of the first board to the middle of the next one should be 28 centimeters, between the middle of the remaining boards - 35 centimeters. It is recommended to check the step of the crate every 5 rows from the first board. Self-laying metal roofing is no easy task. And if you make a mistake with the horizontality of the cornice board, you will have to interrupt the entire crate again.

Near skylights, chimney channels and in the valleys, it is necessary to make a continuous crate, nailing two additional junction strips measuring 150 by 25 millimeters over 300 millimeters to the sides of the ridge strip. If the corner of the valley is almost flat, it is worth laying an additional layer of waterproofing material. The valley is fastened with self-tapping screws to the crate in increments of 300 millimeters. The lower edge of the valley should be laid on top eaves plank. The overlap should be at least 100 millimeters at the horizontal junction of the valleys.

In the chimney, it is necessary to make a strobe (it is strictly forbidden to strobe into the seams of the masonry) with a depth of at least 15 millimeters and carry out waterproofing on the pipe by 50 millimeters, securing the cut with adhesive tape. External junction strips will overlap the pipe, upper part leading into a strobe. This place must be sealed with a high-quality heat-resistant sealant. Also at this stage, it is necessary to provide places for arranging passage elements of the roof - ventilation and antenna outlets.

Fastening sheets of metal

So we come to the main question, how to properly cover the roof with metal tiles. Regardless of the fact that the metal tile is a durable material, when working with it, you should follow some rules. The process of laying metal tiles begins on the ground, you need to unpack and lay out the sheets in piles intended for each slope. Do not handle sheets with bare hands, wear protective gloves.

The technology of arranging a roof made of metal tiles allows cutting sheets for complex areas at the facility. However, you can not cut the sheets with a grinder, as the protective polymer layer may be damaged. Use electric nibblers or metal shears for cutting. Before cutting, practice on a separate piece, as cutting a metal tile is more difficult than an ordinary steel sheet.

When lifting metal tiles onto the roof, it is important not to scratch it. Take the sheet of material when moving over the edge of the stamping line and lift it onto the roof using the board guides. Long sheets are not recommended to be lifted by the edges, because the sheet may bend. Also, do not load multiple sheets at the same time. Remember that to move on the sheets you need to choose shoes with soft soles. Do not step on the crest of the wave, but only on your toes. Place your foot parallel to the slope.

The stacking direction is not tied to anything, so it can be done from left to right or right to left. When choosing the installation of a metal tile from left to right, you will have to lift the edge of the sheet, and place the edge of the next one under it. As a result, the outermost sheet will rest on the previous one, or rather, on its transverse wave, which prevents sheets from slipping. On gable roofs, the installation of sheets starts from the end, and on hip roofs, they are laid from the hip. Align the sheets with respect to the cornices. If you start laying the coating with long sheets, it will be much easier to align them.

When laying the material in one row, the first sheet is placed on the crate, temporarily attached with one self-tapping screw. Then lay the next sheet, aligning with the first, and fasten the sheets together. Make sure that all sheets fit snugly and correctly from a geometric position to each other. Carry out the installation of metal tiles, moving from the eaves to the ridge. After that, attach all the sheets to the crate, and the last sheet in the row is attached to the crate only after leveling the next block.

When laying sheets of metal tiles from right to left in several rows, lay the first sheet, aligning it along the end and cornice, then lay the second sheet on top of the first, temporarily fix it with one screw in the center of the sheet at the ridge, align the sheets and fasten them together with self-tapping screws. Then you need to lay the third sheet on the left side of the first, fasten the sheets together and lay the fourth sheet over the third. Align the entire block along the end and cornice, and then finally attach the sheets of metal to the crate.

When laying material on a triangular slope, it is necessary to mark the center of the slope before starting installation and draw an axis through this center. Then the same axis must be marked on the sheet and the features of the axes drawn on the sheet and the slope should be combined. Fasten the sheet to the ridge with one self-tapping screw. On both sides of it, continue installation according to the principles that were described in the previous versions.

Sheets of metal tiles are attached to each other, to cornices, ends and crates. First, three or four sheets are fastened together at the joints, then they are fixed in place with one screw, aligned strictly along the eaves, and only then the sheets are finally fixed to the crate. Sheets of roofing material are attached to the crate with two self-tapping screws - near the ridge and at the eaves. Continue the installation of the coating in the same way. Brush off the drilling chips with a soft brush after the installation of the metal tile and tint the surface if necessary.

End and ridge bar

To protect the metal tile from the lifting force of the wind and the process of loosening its fastening, an end plate is required. It also acts as a protective element for the structure from moisture. The end bar is installed towards the ridge from the eaves, the excess is cut off at the ridge. Attach this bar to the end board with self-tapping screws every 500-600 millimeters

Due to the difference in heights, the end plate is tightly pressed against the sheets of metal tiles, which eliminates rattling and noise during gusts of wind. The overlap of the end strips should reach up to 100 millimeters. A layer of waterproofing must be laid on top of the end plate, which will cover the edge of the waterproofing material. Also, such a bar should block the upper crest of the wave, to protect the metal tile from water ingress.

For proper ventilation of the space under the roof, air must pass freely to the ridge from the eaves and exit through the holes in the ridge seal to the outside. Lay waterproofing on a continuous crate so that it overlaps the bottom layer of waterproofing material along the edges by at least 150 millimeters.

The ridge is attached to the crate using ridge screws into the upper crest of the wave of the metal tile on both sides. The sealant is attached to the ridge before the latter is installed on the roof, having previously removed the protective film from it.

Upper valley and junction strips

The upper end plank is needed to remove moisture from the inner corner of the roof, located at the junction of two slopes. They fix the valley with self-tapping screws so that they do not pass through and do not damage the waterproofing. Remember that a self-expanding sealant must be laid between the sheets of shingles and the upper valley.

Between the planks of the valley, it is also necessary to leave ventilation gaps, about 20 millimeters in size, and to make an overlap of 200 millimeters at the joints when laying the planks. The corner sheet of the valley must overlap the sheet of roofing by at least 250 millimeters.

Special strips must be installed on the breaks of the roof and when the roofing adjoins the wall. Roof fractures are reverse and direct. In places of fractures, continuous waterproofing is recommended. The boards of the crate with a direct fracture of the slope to each other should be as close as possible. A metal tile sheet covering the breaks in the slopes should protrude slightly above the break in the roof and thus close it.

In the case of a reverse fracture of the roof slope, you can use the junction with the wall as a mating element, placing it on the lower slope with the rolling side. The adjunction of the roof to the wall is arranged according to the same principle as the procedure for adjoining the pipe. The waterproofing is removed and lifted onto the wall, at least 50 millimeters to the strobe. Depending on the junction - to the end or side of the wall, a universal or profile seal is used.

Mounting gutters and snow retainers

The installation of long hooks is carried out on a cornice board or rafters before covering the old roof with a metal tile. For better water flow, the slope of the gutter should be at least 5 millimeters per linear meter. It is customary to install hooks with a vertical offset. To insert the chute into the hook, you need to bring its spout into the chute in such a way that the spout is inside the curl.

Then you should fix the other edge of the gutter with a cap plate clamp. The outer edge of the gutter must be 6 millimeters lower than the inner edge in order to prevent water from entering the facade during a heavy downpour. The continuation of the edge of the metal tile should hang over the gutter by 50 millimeters. The connection of the gutter with the corner of another gutter or with the next gutter is made end-to-end using a special connector.

The gutter connector is equipped with a special rubber gasket that provides a hermetic connection of two gutters, as well as compensating for thermal expansion. The downpipe should be of such length that the drain elbow is about 200 millimeters from the ground or a moisture-resistant base, as water splashes if it is too high. To organize the withdrawal of water, it is necessary to equip a storm sewer.

It is imperative to install snow guards on a roof made of metal, because thanks to these products, snow will not fall on your head and will not scratch the roofing material when it comes off. Snow holders are attached under the second transverse step of the metal tile parallel to the eaves. They are installed under the crest of the wave in the bars that were previously attached. The lower edge of the snow retainer is attached from above on every second wave. With long slopes, it is recommended to install snow retainers in several rows.

Lightning rod and roof grounding

To install a lightning rod and a weather vane, prepare a metal bracket, a compass, metal screws, as well as wrench. Weathercocks can be mounted on a ridge, roof end or spire. For security metal roof needs to be grounded. This is done in order to protect the roofing material from damage and protect the inhabitants of the house when lightning strikes the roof. Such a system consists of a down conductor, a ground electrode and a lightning rod.

The lightning rod is installed at the highest point of the roof using wooden props. The down conductor is attached to the lightning rod and lowered along the crate under the sheets of tiles. It is welded to the lightning rod, and where it comes into contact with the sheets of metal, it is removed protective covering or a coat of varnish. For greater contact between the points, it is worth branching such a wire into several sheets so that the lightning can quickly find the path of minimum resistance.

Then conduct a down conductor along the wall of a residential building and connect it to the ground electrode. It is recommended to carry out the down conductor along the wall, which is opposite to the entrance. To equip the grounding of the roof, you need to dig a hole 1.5 meters deep, fill it with a layer of sand 10 centimeters, fill it with water, lower the ground electrode there, fill the hole with soil and pour water over it.

Now you have learned how much it costs to cover the roof with metal tiles, and how to do it correctly. But that is not all! Additional elements are included with each ventilation or antenna outlet. First you need to attach a passage element template to the metal roof or ventilation outlet and circle around. Then you need to cut a hole along the resulting line. Outlets and passage elements are fixed to the metal profile with special self-tapping screws.
