Roof covering with corrugated sheet is gaining more and more popularity in comparison with the use of roll or liquid materials.
This type of coating consists of a metal sheet with a polymer layer.
The combination of these two materials provides the coating with durability and resistance to external influences. We considered how to cover the roof of a garage with corrugated board with our own hands, what advantages and disadvantages does a garage roof with our own hands from corrugated board have, what types of material exist.
Among the advantages of this roofing material is its durability. The service life is about 25 years, which is comparable to the service life of a more complex metal or bituminous shingles, and much more than the service life of bitumen insulation or ondulin. The product is resistant to corrosion due to the presence of a polymer protective layer.
A roof made of corrugated board has a significantly lower weight than a covering of slate, roofing felt or other insulating materials.
Due to the low weight, minimal pressure is created on the walls and foundation of the structure. Even an amateur is able to overlap the garage; complex tools and construction equipment are not needed in the work.
Also, such products are fireproof. When ignited, the sheets do not generate heat, melt, or promote the spread of fire.
Manufacturers offer a wide range of color schemes, and it is worth noting that such materials, unlike ondulin, do not fade in the sun.
The wide range of options suggests a wide price range. The cost varies depending on the thickness of the product. In terms of prices, this material is cheaper than metal or bituminous tiles, but a little more expensive than ondulin.
But this building material also has disadvantages. One of the downsides is soundproofing. When it rains, droplets hitting a metal surface make a lot of noise. You can eliminate this minus by applying mineral wool, which will serve as sound insulation. If the polymer coating is damaged, moisture begins to appear under it. Spreading fast under protective layer, it leads to base corrosion.
Types of materials
Before making the roof, it is worth choosing the right material. It comes in three types:
- front;
- carrier;
- wall.
The first selection criterion is the presence of a drain groove, it is needed to drain rainwater. The carrier and wall covering... Therefore, the roof of the garage with profiled sheeting is made from them with their own hands. You should also pay attention to the thickness of the product. You can identify it by the manufacturer's markings.
- S-21 - a rigid profile for the formation of the roof. Suitable for laying on wooden battens in increments of up to 80 cm;
- RN-20 - sheets 110 cm wide, equipped with a capillary groove.
- S-44 - profile with additional stiffeners.
- NS-35 - high-strength building material for roof and wall floors.
GOST will help you determine the conformity of the product to your particular structure.
Also in the choice is to assess the condition of the product. It should be free of sagging, chips, scratches and cracks on the surface. When bending, the polymer coating should not crack, and the sheet should return to its original shape.
How to cover the roof with corrugated board
Similar products are used for both monolithic and lightweight, frame structures. If you plan to equip an attic, then profiled sheets are ideal for these types of structures.
The most inexpensive and easiest to build is a lean-to design.
It does not create a high load on the structure and does not require a large amount of building materials. Therefore, consider how pitched roof to the garage from corrugated board.
Preparatory work
The planning of the roof structure begins at the time of designing the walls, since even on flat buildings a slight slope must be observed. It is necessary so that rainwater does not stagnate on the surface, but flows down from the roof.
For this, during the construction of walls, one is made slightly higher than the opposite. When calculating the angle of inclination, it should be borne in mind that the larger it is, the stronger the load on the foundation, and the easier the building materials should be for insulation. The optimal angle of inclination for covering with profiled sheet is 10 degrees.
To begin with, a bar is laid along the entire perimeter of the walls, on which the rafters are installed. Next, the roof lathing is made. It is collected from a thin bar and treated with an antiseptic against moisture and insect exposure. Then the sheet waterproofing is laid and you can proceed with the installation.
The seams between the sheets can be additionally insulated with a sealant to prevent moisture penetration under them.
How to fix the profiled sheet on the roof
Use logs to lift the sheets up. Laying is done with an overlap. For models NS-8 and NS-10, the overlap is done in two waves, for other options - in one.
If we talk about horizontal overlaps, then their size depends on the angle of inclination of the structure.
For example, for buildings with an inclination of 15 to 30 degrees, the overlap is 20 cm, for an angle of more than 30 degrees, 15 cm is sufficient.
Laying starts from the lowest point. Each sheet is fastened with self-tapping screws with polymer inserts. Attach the coating to the base at the lowest point of the wave, where it touches the base.
Repair of a garage is done by replacing a whole sheet or a fragment thereof. For replacement, products are used that are similar in thickness and shape.
How to cover a concrete roof
The most popular building material for concrete roof protection is sheet insulation. But the profiled sheet provides more reliable and durable protection.
To mount it on concrete surface the construction of a wooden frame will be required.
It is installed on special Mauerlats and consists of rafters and wooden sheathing. Waterproofing is laid under the crate, if necessary, you can use insulation. Next, the material is installed.
The calculation of overlaps is carried out similarly to construction wooden roof... It all depends on the angle of its inclination. The larger it is, the smaller the width of the overlap. This is necessary to reduce the load on the walls and foundation of the building. Editing starts from the lowest point. Gradually, the sheets are stacked to the very top and are fixed at the edges with special corners. Sheets are fastened with self-tapping screws with rubber substrates, which do not injure the polymer surface of the coating.
Now you know how to make a garage roof from a profiled sheet with your own hands, what types of materials are, their advantages and disadvantages.

Everyone who started construction sooner or later wondered how you can cover the garage roof quickly and efficiently. It can be a wide variety of materials, each of which has its own characteristics. But the most notable is the profiled steel sheet, which has numerous advantages and which can be supplied independently without resorting to expensive work of specialists and teams.
Advantages of corrugated board: low cost of material, lightness, durability, ease of installation, the ability to lay over the old roof material.
In our article, we will consider not only the advantages of corrugated board as a roofing material, but also possible options for installing garage roofs, types of roofs, technology.
Types of roofing materials for garages
So, it can be not only corrugated board, but also slate, roofing material, folded roof. Consider the various coating options and their pros and cons.
Slate or decking on the roof?
Slate is one of the cheapest options for covering your garage roof. This is a fairly wear-resistant building material with a service life of up to thirty to forty years. It is lightweight and fixed with galvanized nails through drilled holes.
According to the material of manufacture, this is an asbestos-cement slab, which, during installation, requires a wooden crate, the sheets are overlapped. Repair of such a coating is a rather rare phenomenon, usually you just need to patch up holes and cracks, for which a mixture of PVA glue, fluffed asbestos and M300 cement is used. Among the shortcomings, it should be noted the fragility of this material, its external unattractiveness.
The roofing of corrugated board has a higher price, since a hot-dip galvanized metal sheet is used as a base. For roofs, use a profiled sheet of marking NS or N.
Laying is carried out with an overlap in two waves, fixation is done using special self-tapping screws with rubber gaskets, which are screwed into the groove of the wave to the crate.
Among the advantages are the strength and rigidity of the roof, its resistance to adverse weather conditions, and low weight.
Seamed and soft roofs
The hip roof of the garage is difficult to design. Usually installed for garages if it suits the design of the roof of the house.
Seam roofing is very light and attractive, but the installation process can be difficult for a person who does not have the appropriate experience. In addition, it takes quite a lot of time to cover a garage roof with this material. Soft roofs made of roofing material and similar material differ in appearance and excellent performance, but their cost is quite high, and laying requires skills.
Especially it concerns shingles, the amount of which can only be calculated by a specialist, and for laying many additional materials are required. Often, the cost of installation exceeds the price of the roofing material itself, which is not always beneficial when building an ordinary garage.
The advantages of corrugated board
Profiled sheeting is a material that is produced from steel sheet using the cold rolling method, that is, the sheet is first passed through a special machine, which gives the metal a profiled surface with waves of various sizes and shapes, then the sheet is hot-dip galvanized to protect it from corrosion and damage.
Some types of corrugated board can be coated with polymer paints and varnishes of very different colors. Such a layer provides visual appeal, additional protection from numerous external influences.
Decking with such polymer coating has a longer service life, it looks better as a roofing material.
Waterproofing materials and insulation
To, it is necessary to provide waterproofing. For this, a special PVC membrane is used, which is placed under the rafters. Such a film will not damage moisture indoor spaces and structural elements.
After that, between the individual beams of the roof, a heat-insulating material is tightly placed, which can be soft or hard. Most often, foam and mineral wool are used for garages, which have excellent characteristics.
As you can see, it is quite simple to make your own garage roof using corrugated board, the main thing is to choose the right type of roof, take into account the design features.
The roof structure of a garage can be with an attic. In this case, the roof and ceiling look like a one-piece structure, requiring the installation of rafters. Depending on the planned dimensions of the attic space, the shape of the roof and the angle of inclination of the planes are selected. Everything can be done by hand if you follow the instructions clearly.
It must be remembered that when the angle of inclination of the roof should be less than 12-15 degrees, leaks are possible during rains or when the snow cover melts.
The procedure for installing a roof with a large slope
If the roof has a slope of more than 16 degrees, then the seal is not needed. To fix the garage starting sheet, you only need to use one pre-fixing self-tapping sheet. After all the profiled sheets are laid and aligned according to a special scheme, it is necessary to make finishing mount and cover the structure completely.
If a decision is made to cover the garage longitudinally, then the fasteners of the first profiled sheet must be made into the crest of the wave, and where there are vertical joints, it is better to make fasteners at the bottom of each wave. And then all the sheets of the garage corrugated board are fixed to the wooden crate at the rate of 6-7 self-tapping screws per 1 sq. m roof covering.
After you have managed to cover the main area of \u200b\u200bthe roof with your own hands, you should install the strips (end and ridge). It is not recommended to seal the ridge strip for unhindered natural ventilation of the garage roof.
Preparatory work for fastening the roof
Among all the processes of installing roofing materials, laying corrugated board on the roof is the simplest and best option. In order to make a roof, you will need the following tools:
- electric drill;
- screwdriver;
- electric scissors or a hacksaw for metal;
- a hammer;
- roulette;
- construction cord;
- special screws.
Before you start with your own hands, you should calculate the length and width of the slopes required amount sheets of corrugated board for the roof according to measurements. Choose the optimal location of the corrugated board so that there is no large waste. Where metal cutting will be carried out, it is recommended to make the treatment with an anti-corrosion compound.
Before you make a garage roof with your own hands, there are a few things to consider. First, the climatic features of the area. In case strong winds are possible, the garage roof should be reinforced with additional fasteners. Secondly, they must be very dense.
Roof mounting technology and fastening instructions
When the corrugated board is fastened with your own hands, you should pay attention to the fastening of self-tapping screws, which should be done in the lower bend of the wave. Be sure to pay attention to the end parts of the garage roof, where self-tapping screws must be screwed to all the bars that are located along the width of the entire roof slope.
In the upper part of the garage roof, self-tapping screws are screwed through a wave (every second). In the middle of the corrugated board, you should do it yourself, placing the screws in a checkerboard pattern. It is recommended to buy self-tapping screws at the rate of 7-8 pieces per m 2.
Step-by-step coverage instructions:
The size of the overlap depends on the slope of the garage roof. The greater the slope, the less overlap. A maximum overlap of 200 mm is performed on a 15 degree slope.
- The garage is covered with corrugated board from the bottom corner of the first corrugated sheets. The sheets themselves are aligned relative to the eaves. When the corrugated board is leveled, it is necessary to ensure that the required overlap is maintained. It all depends on the slope of the garage roof. The greater the slope, the less overlap. A maximum overlap of 200 mm is performed on a 15 degree slope. If the roof of the garage is sloping, it is necessary to apply the rules of water resistance, the joints of the corrugated sheets are sealed. The gutter groove goes down.
- With different lengths of garage slopes and corrugated sheets, the outermost roof sheets are stacked with side overlap (overlap). The width depends on the depth of the wave. If the corrugated board is of low depth, the overlap provides for two waves.
- Self-tapping screws are screwed into the corrugated board with their own hands with mandatory technological accounting. The lack of self-tapping screws will lead to a decrease in the performance properties of the garage cover.
How to choose the angle of the roof slope
In order to cover the roof using galvanized material, the slope angle must be determined. It all depends on the height of the walls in the garage. Also, before covering the garage with corrugated board, it is necessary to take into account the local climatic conditions (namely, precipitation, wind load).
Depending on the quality and brand to which the corrugated board belongs, the angle of inclination is also selected. Typically, the interval is 8 to 15 degrees. If you define a smaller angle, then during the period of numerous precipitation, the corrugated board may not withstand the loads. Then the garage will be under threat, and the corrugated board will simply bend. The waterproofing layer also depends on the angle. If the garage provides a maximally flat shed roof, then a denser waterproofing layer will be required.
Advice: it is necessary to place self-tapping screws on the roof sheets keeping a distance of about 50 cm between them. It is recommended to connect the profile shelves to each other with rivets of small diameter.
Nowadays, not everyone wants to build a major garage for their car from blocks or bricks. Firstly, it is expensive, and secondly, the construction takes up too much space on the personal plot, so many refuse this venture. However, according to experts, in order to maintain the car body in a satisfactory condition, it should be stored in the garage. DIY garage made of corrugated board can serve as a great alternative to a traditional garage. A practical, lightweight construction, it is erected quite quickly and easily. In addition, it is more profitable to build, even according to an approximate calculation, its cost will cost you at least Five times cheaper than brick, in addition to this, add the saved amount on builders. The technology for erecting a garage from corrugated board is quite simple and does not require the involvement of expensive specialists.
The first thing to start with is choosing a suitable place for future construction. It is desirable that the garage is located as close as possible to the exit from the site. This arrangement will allow the land behind it to be used for other purposes. If the garage is taken inland, it will be impossible to build or plant something in front of it, as this will prevent access to it. 
The selected site for construction should be as flat as possible, and its location should comply with urban planning standards.
- The fire-prevention distance from the borders of the adjacent site is not less than 1 meter, from other outbuildings (houses, baths, shed) not less than 6 meters;
- The minimum distance from the red lines is at least 5 meters. P.S. Red line - this is the conditional location of underground and surface engineering networks (power lines, gas, pipeline), which are indicated in the construction documentation.
- If there is a small artificial pond or pool on the site, the garage should not be closer than 3 meters to it.
The optimal size (width, length, height) of the garage for convenient placement of one vehicle unit is 3.3 × 5 × 2.5 m... for two - 5.3 × 5 × 2.5 m... respectively
Garage roof made of corrugated board
A garage made of corrugated board is a fairly simple construction in terms of construction, so it makes no sense to build a complex or hipped roof on it. The traditional single-slope one will either be the best option for this garage.
Shed roof for garage
The slope can be located both in length and in width. Experts recommend the side of the garage, which is higher up against the wind side. There are no special difficulties when installing a pitched roof, it is only important to correctly set the slope, which will ensure the independent descent of snow and water. For a standard garage, in most cases, the angle 12 ° -15 ° is sufficient.
Shed roof garage - slope options
Gable roof for garage
The gable roof, in addition to its attractive appearance, has a more reliable, durable structure, as well as an improved natural, since the length will be longer.
In addition, it is possible to equip the attic floor for a small utility room. Of course this will come with a slight price increase, but the aesthetics and extra space are worth it.
Material for building a garage
Most often when erecting garage from corrugated board,use wall profiled sheet of the brand PS-15 and S-15 with thickness 0.5 mm... The number 15 means the height of the wave, the larger it is, the stronger and tougher the sheet of metal. By using this marking for construction, you are guaranteed to get the most durable structure. 
In addition to professional sheets, you will need the following:
Garage foundation
It is a fairly light construction, so it makes no sense to build a powerful foundation for it, or it will be quite enough. Choosing from the two, it is still better to give preference to the second option, since in addition to a reliable base for your building, the slab will play the role of a floor in the garage.
How to fill the foundation for a garage?
- The first thing to start with is marking the site and cutting the soil from it to a depth of at least 50 cm... Further into a pit made of sand or crushed stone with a minimum thickness 20 cm... carry out a bedding (pillow), which is tamped tightly with an area vibrator.
- To give the foundation strength, using a drill, holes are made in the places where the frame racks will be located, preferably to the depth of the average soil freezing rate in your region. Later, pipe segments will be inserted into these holes.
- The next step will be the construction of the formwork. To do this, using boards or moisture-resistant plywood, shields are knocked down, which are installed around the entire perimeter.
- Further, on the bottom of the excavation, reinforcement rods (with a diameter Ø10 mm.), which are tied together with ordinary wire. This creates a one-piece metal grill.
- In the pre-prepared holes, pipe sections are installed strictly vertically, which should protrude 20-30 cm above the upper level of the foundation. The lower part of the pipes, which will be in the ground, should be treated with an anti-corrosion compound. Bituminous mastic is best suited for these purposes.
- Concrete is poured into the finished structure, which must last at least 25 days. For monolithic slab it is best to use concrete grade M 400.
Garage frame
While the solution dries up and gains strength, you can start building the frame. Despite the fact that it is being built quite easily and quickly, it will not be superfluous to get a partner to help. The sequence of works can be described in the following order:
- First of all, according to the dimensions specified in the drawing, it is necessary to cut the pipe for the vertical struts. The pipes are welded to the pre-concreted workpieces mentioned above.
- Horizontal crossbars are welded to the vertical posts along the entire contour, so the frame acquires the necessary strength and rigidity, after which you can proceed to the installation of the roof.
- Depending on the type of roof chosen (single-slope or dual-slope), the upper crossbars are welded to the posts. For a roof with one slope, work is done immediately on the spot, but for gable roof it is easier to weld a truss on the ground. To do this, it is necessary to correctly mark the first template, according to which the rest will be made. If necessary, the trusses are reinforced with struts and crossbars.
- The final stage is the welding of the gate frame. Along a given length, at an angle of 45º a metal corner is cut, which, after making sure that the diagonals are equal, is welded together into rectangular structures - gate leaves.
The welding process is quite laborious and, moreover, dangerous. Therefore, not having enough experience in this matter, it is better to seek help from a professional welder who will be able to perform this work efficiently and quickly.
Fastening corrugated board
Only after the concrete is completely dry, you can start covering the frame. Previously, it was not recommended to do this, since during curing the concrete may slightly affect the frame, which will lead to deformation of the metal sheets. For better water flow, fix corrugated board follows in a vertical position overlapping by one wave. This technology is applicable to both garage walls and roofs.
It is desirable to use a special self-tapping screw with a hex head with a rubberized washer for fastening.
- You need to start wall cladding from the bottom row. First, the upper corner of the first sheet is attached to one self-tapping screw. Then the level is checked for its horizontal and vertical position, if everything is in order, the sheet is fixed in other places.
- Each subsequent sheet should overlap the previous one by one wave, where both elements are tightly fixed to the frame in several places. Thus, row by row, all the walls of the garage are sheathed.
- The roof sheathing is carried out using absolutely similar technology. Just before starting, you should take care of installing the elements drainage system... After all the sheets are finally fixed, all that remains is to make the installation end plates and ridge elements.
Important!When working at height, you should be extremely careful and follow safety precautions.
A garage made of corrugated board is an excellent construction for temporary storage of cars, which has already become a real salvation for many motorists.
In contact with
In the construction of houses and structures for various functional purposes, corrugated board is often used as a roofing material. Decking is quite popular with consumers due to its performance and affordable prices. Profiled sheeting is characterized by versatility, resistance to temperature extremes and the formation of corrosive processes, and a long service life. Read on.
Device
The device of the garage roof made of corrugated board is a kind of "pie" of building materials... The structure of the garage roof includes a layer of thermal insulation (as thermal insulation material usually foam or mineral wool is used), a layer of waterproofing (a special PVC membrane is used), a frame ( rafter system) and himself roofing material (professional flooring).
How to do it?
How to cover the roof of the garage with corrugated board, see the video:
Before proceeding with the installation of corrugated board on a concrete roof, it is mounted wooden frame... The corrugated board is fixed with special self-tapping screws, which are located in the depth of the corrugation. The edges of the corrugated sheets used are decorated with a decorative strip (metal profile).
When conducting installation works to overlap the roof of a metal garage with corrugated board, as a rule, one-piece sheets are used (without increasing the length, due to laying additional rows). Laying the corrugated board begins from the outer sheet, which must be aligned with the eaves and fixed with screws. Sheets of corrugated board are overlapped, forming one wave. If, nevertheless, the roof of the garage has a significant area, then the laying of the corrugated board begins from the bottom row, and the subsequent rows of the corrugated board are stacked with a shift relative to the first row. Be sure to leave an overhang of the corrugated board on the sides, about four centimeters, to prevent the walls from flooding during rain.
Flat roof covering
It is quite simple to mount a pitched roof from corrugated board for a garage. To do this, it is necessary to build a wooden frame (install rafters with supports), the lathing is assembled across the laid roof rafters (beams). The angle of inclination of the roof will depend on the area of \u200b\u200bthe roof. Keep in mind that everything wooden parts treated with an antiseptic. Then the sheets of corrugated board are attached to the pre-assembled frame. Read the instructions on how to cover the garage roof with bikrost.
