We fix the corrugated board on the roof of the house correctly with self-tapping screws: Review + Video Any construction involves a large amount of costs. The use of modern profiled materials allows you to significantly save at one of the stages of your repair. These savings are related to material costs and self-assembly.

If we compare metal tiles with profiled sheets, it can be noted that the second option is several times cheaper, and when buying natural tiles, repairs will cost you even more.

In addition to financial savings, roofing sheets have many other advantages:

  • Small unit weight of the entire usable area, the smallest among the existing elements and materials.

    This advantage allows the use of load-bearing rafters of a smaller cross-section in construction than in the construction of a large and massive roof. Thus, the cost savings will affect your entire roof.

  • High corrosion resistance. The standard profiled sheet is a sandwich construction where steel is just the basis for overall reliability and strength. Polymer or zinc coatings, resistant varnishes and special sprays are applied to the steel surface.

  • Huge selection of colors. The final polymer coating can be made in any color. But you need to take into account that when choosing a corrugated board in dark colors, it will quickly fade in the sun. Better to choose a standard shade of red or blue, brick or silver. These colors retain their original rich color for a long time.

  • Ease of installation and ease of installation due to the low weight of the sheet and the ability to smooth out all the unevenness of the roof. All other roofing materials have a high geometric severity of floors and other supporting structures and structures.

In heavy rain, the sound from the drops will be amplified several times due to the vibration of the sheets. As a result, residents of the upper floors will feel like they are inside a big "drum" during a heavy downpour.

The "drum effect" can be reduced by insulating the roof and creating a special acoustic barrier between the roof and the rafters.

Scope of the profiled sheet

The metal sheets can also be used for such repairs as:

  1. Facade cladding (replacement of expensive siding) with back sides of walls, for buildings of economic use, etc.
  2. Installation of solid fences from profiled sheets is the most budgetary option for construction.
  3. Equipment for greenhouses, sheds and poultry houses.

Before learning how to fix and install profiled sheets, put on a small experiment.

Try to trim the visor above your door with a professional sheet yourself. All the main installation and installation techniques must be applied for such a small construction area. When mastering these works, this will help you in further full-scale construction work.

Installation and fastening of the corrugated board on the roof

Let's consider the step-by-step instructions for fastening and installation of the corrugated board on the roof:

We fix the corrugated board on the roof of the house correctly with self-tapping screws: Review + Video 1) Rafters for the profiled sheet have a certain degree of slope (not less than 8%). As a rule, this angle is equal to a rise of 1 meter with a roof length of 7 meters.

It is worth noting that the greater the slope of the roof, the less requirements for fastening the joints between the profiled sheets. With a sloping flat roof (less than 8 degrees), it would be wiser to call specialists to install the roof, because it will be quite difficult to achieve the tightness of the installation on your own at a lower slope angle.

If your house already has a building frame, all bad or damaged boards need to be replaced and the soundproofing and insulation finished. Think over all movements on the roof in advance, provide special supports for the legs, also use a mounting belt. The main thing when laying a roof is safety measures!

2) It is much easier to install and mount profiled sheets on a reliable and high-quality rafter system than to lift all the material into the working area.

If installation and installation is within the power of one worker, then you will definitely need an assistant for the rigging stage of construction. It is more convenient to lift profiled sheets on the roof in bundles of 10 sheets, and this must be done very carefully. Damage to the material will lead to future corrosion of the metal. Fastening of bundles of sheets is carried out using bars or special lag rails.

3) It is necessary to cover the roof with sheets from the bottom up, from the overhang to the ridge and from the visible end.

Initially, the membrane is attached to protect the heat-insulating layer from condensation. Typically, a diffusion membrane is selected and nailed to the rafter battens. The approximate gap between the nails is about 25 cm and it is important to make sure that all the nail heads are completely inserted into the wood.

The first row of corrugated sheets must be laid with overhang above the edge of the roof by 50cm, the final final size will depend on the gutter system. Before starting the fastening of the profiled sheets, determine the size of the overlap.

Between the panels of sheets, the overlap is performed by at least one wave. If the wave of the corrugated board is not very large (up to 15-20 mm), and the roof is sloping, then the overlap between the sheets should be done in two waves. And there is no need to be afraid of overspending of material, quality and reliability are much more important.

Then, when replacing sheets in the future, they can be easily dismantled.

Fastening of profiled sheets to the frame is carried out using self-tapping screws or screws with special sealing washers, up to 10 screws per square meter of material.

4) Adjacent rows of profiled sheets are made in height with an offset of half their size from the end.It is necessary to cut the sheets with sharp metal cutting, this must be done on the ground, since it is not safe on the rafters. The overlap of sheets on a sloping roof is up to 25 cm, on a steep roof slope 10 cm will be enough. And as we already wrote above, be sure to seal all joints.

Joint screws are installed in each deflection groove, through the wave. If the rubber washer is visible when installing the screw, it is very tight.

5) After you have reached the ridge of the roof, an important stage of work begins. Having installed the last sheets, mount a wide end plate on top of them. Fasten it in increments of no more than 25 cm, while maintaining an overlap between the planks of no more than 10 cm for a special water drain.

Before installing the slats, carefully inspect them for chips, scratches and the entire integrity of the coating - because a leak from the roof ridge is eliminated with great difficulty. The ridge strips and various design elements of your new roof will be installed last.
