We cover the roof with corrugated board with our own hands

In this article, we will look at how to cover the roof with a corrugated board with your own hands, how to choose this material correctly and not to allow errors in the installation.

It's no secret that the roof is the main element of the whole house, and the durability of the entire structure will depend on the correct installation and quality roofing.

There is a wide choice of materials for construction works in building stores, but the leader among them is profiled sheeting.

It appeared in the market of building materials quite recently, but gained great popularity due to a huge number of advantages, such as:

• ecology;
• durability;
• resistance to natural phenomena;
• can withstand heavy loads;
• aesthetics.

And if you think about how to properly cover the roof Decking, then you made the right choice, especially as the installation of a pent roof can produce himself, without building skills.

We will tell you how to do this, following all the rules and instructions for installation.

Technical data for corrugated board

Before starting the installation work, it is necessary to familiarize yourself with the characteristics of this material.

The corrugated board consists of layers: a steel sheet, a zinc layer, an anti-corrosion coating, a primer coating, a polymer coating and a protective mounting film.

This technology makes the corrugated board from corrosion, gives stability from natural precipitation, increasing the service life several times compared to other similar materials.

Modern companies for the production of corrugated board produce its various colors, thickness, size and value.

The most convenient and cheap option - to choose the sheets of corrugated board, which coincide with the length of the slope of your roof.

This will help avoid horizontal joints during installation, and will protect your roof from leaks.

If the length of the sheets is shorter than the length of the ramp, then it will be necessary to make an overlap and additional sealing of the joints from penetration of moisture, this will complicate the installation process.

Advantages of using profiled sheets

Before you receive the instructions for mounting the corrugated board, we recommend to learn about the merits of this material:

• has a small weight - it is easy to assemble, no thickening of the crate and rafters is required;
• a small price - will be a good solution for modern houses and to cover the roof of the garage with corrugated board;
• attractive appearance - multi-colored coating of profiled sheets, you can choose the color under the overall appearance of your structure;
• durability - with proper laying of sheets, the coating will last more than 15 years reliably without additional costs and work;
• quick installation - roofing work with profiled sheets is much faster than with other building materials.

Also the laying of this material does not require the attraction of paid labor, and the installation can easily be done manually, the roof overlap will take no more than a couple of days, even if it is made from scratch.

Calculation of used material

First you need to take into account the climatic zone of your residence, in regions with a high amount of snow deposits, profiled sheets must be selected with a wave height of not less than 20 centimeters.

The slope of the roof slope must be at least 15 degrees. At this angle, the slope of the ramp should be 15-20 centimeters.

Video:

Depending on the slope of the ramp and the calculation and number of profiled sheets necessary for laying the roof with profiled sheets are carried out. When calculating, take into account the overlap and overhang from the edge of the roof.

Vertical overlap is performed by overlapping one wave. In the ideal case, when the length of the sheet coincides with the length of the slope, it is necessary to take into account the increase for the overhang from the eaves of not less than 4 centimeters.

When calculating the material, do not forget to take into account the end, ends, pipes, etc.

Preparatory work for

The entire process of laying profiled sheets on a single-deck roof can be divided into 2 stages - preparatory work and installation.

If you do not have the ability to handle the corrugated board, the preparation stage can bring a lot of trouble.

Regardless of the fact that this building material has increased strength, it is very easily deformed when loading, unloading or unloading.

In order to avoid damage to the material, it is necessary that the technology and the rules given below be met.

Transport of material:

• during transportation, the profiled sheets must be stacked on a solid base, for example, on a wooden pallet, which in size must exceed the dimensions of the corrugated board;
• reliably fix the sheets to prevent slip of one profiled sheet on the other - this can damage the protective coating, and there should also be no displacement of the sheets.

Sheet unloading and transfer:

• sheets must be transported strictly in an upright position to avoid deformation;
• transfer is carried out only on one sheet, it is best to carry this material together.

Lifting of profiled sheets on the roof:

• sheets are raised only in windless weather to protect them from damage;
• lifting from the ground to the roof is best done on the previously prepared lags;
• also raises the corrugated board one sheet at a time.

If the sheet is deformed, it is impossible to restore it to its original form, and it becomes more inconvenient for mounting, and damage to the mounting protective film will lead to the rapid formation of foci of corrosion.

Waterproofing for profiled sheeting

As a waterproofing under profiled sheets a huge amount of modern materials is used, but the most urgent is the question whether it is possible to use roofing material as a waterproofing for profiled sheeting?

In this we will try to understand.

Of course, roofing material is an indispensable material, it has been used for a long time and not only for roofing. The ruberoid has very good hydro- and sound-insulating properties.

So, from the number of pluses it is impossible not to note the small cost of this material.

The most important point when laying waterproofing is that the roofing material must necessarily have an air cushion for ventilation in order to avoid decay.

Also, air circulation will not allow the smell of bitumen to penetrate into your room on hot days.

Technology laying is not difficult, for a better understanding of the process, you can see the video provided below.

Video:

The roofing material is laid as a waterproofing in this way: rafters are the first stage, laths are laid on top of them, a roofing material is laid on the lathing, a counter-lath needs to be placed on the roofing material( it is usually made of 2-3 cm thick rails)how the roofing cake is laid, sheets of corrugated sheet are laid.

Ruberoid to the crate is attached using nails with a rubber washer.

Mounting of corrugated board

Here and the most important stage of how to cover a roof with a corrugated board.

Profiled sheeting can be covered with a saddle, gable roof, gable roof, and it is also suitable for roofing more complex geometry.

In order to install the profiled sheets in the right order, you need to perform simple laying technology. We will consider it on an example of installation of a single-pitched roof.

Installation work on the laying of profiled sheets on a single-deck roof starts from one of the lower corners of the butt. The first sheet is attached using a single screwdriver at the cornice.

Next, the second overlapping sheet is placed in one wave, which is aligned with the first one.

Having laid thus 4-5 sheets, they should be leveled on a cornice line of a one-pitched roof and to fix definitively.

If the installation involves several horizontal levels of stacking, the horizontal overlap must be at least 20 centimeters.

Now as to how to properly fix the corrugated board to the roof. Fixing sheets of corrugated board are made to deepen the wave with galvanized screws with a rubber gasket.

Also note that the mounting technology strongly recommends you to move on the roof, only stepping into the recessed wave of the already fixed sheet in shoes with soft and non-slip soles.

It is also not possible to perform installation work during the rain, because the coating becomes slippery, it is very difficult to hold onto it even with a small angle of the slope, which can lead to injuries.

If scratches are formed on the corrugated board as a result of transportation or installation, they must be covered with a special polymer coating intended for profiled metal sheets.

Mount the ridge

After finishing the laying of sheets of corrugated board it is necessary to install a skate. In order to install the skate, it is necessary to lay a special bar measuring at least 7x9 centimeters.

To it are fastened bars. The beam, laid down under the hobby, it is desirable to wrap a layer of roofing material. The hitch is installed with self-threading screws with a rubber gasket.

Laying the elements of the ridge is necessary on the leeward side with an overlap of not less than 15 centimeters.

The step of fixing the screws should be about 20 centimeters. Also, if the ridge sheets have small corrugations, then it is necessary to lay the sealing layer.

That's the whole instruction on how to cover the roof with corrugated board, follow it, read the video and you will not have any difficulties with the installation work on the arrangement of your roof.
