Roofs made of various sheet materials are quite old, reliable and convenient construction. And one of the most experienced and successful players in this market is corrugated roofing. How roofs are made of it, and what nuances you should know when installing them - later in the article.
Corrugated sheet has been produced for quite a long time and has proven to be a convenient and reliable material. It is produced by rolling from rolled galvanized steel, as a rule, with a thickness of 0.35-1 mm. Standard sheet size: 930x2000 and 1150x2500 mm.
Now there are improved versions of corrugated sheet, which, in addition to galvanizing, also have a layer of polymer coating for roofs of houses. This is not only a higher degree of protection against harmful atmospheric influences, but also an element of decorative finishing of roofs and fences.
Advice! Although a corrugated board with a polymer layer will cost a little more than a regular galvanized one, if all the installation work is done correctly, an additional coating will really significantly extend the life of the roof.
Why choose corrugated sheet for roofing? There are several reasons:
- It is light - therefore, load-bearing structures can be quite light.
- The corrugated profile increases the longitudinal bending strength of the sheet (withstands a force of up to 250 kg / cm2), so it does not need frequent lathing
- Durable - under normal conditions, the roof can last about 50 years
- On average cheaper than other sheet materials
- Easy to install
- It is possible to choose a material with a polymer coating, and there are several types of coatings
Features of installing corrugated roofing
Decking is a fairly democratic material, and the installation of such a structure as your roof from it is easier than from most sheet materials. There are several basic rules that will allow even a beginner to carry it out in accordance with the technology.
Important information! All work on laying the corrugated sheet should be carried out in soft shoes, without elements that could damage the protective coating. You should also keep a close eye on it. that prepared or laid sheets are not damaged during tool preparation. Damaged areas should be covered with special mastic.
Sheets cannot be cut with a grinder - only with a high-speed saw or a hand saw for metal! Before starting installation, you must make sure that there are ridge, chip and other shaped elements.
- Corrugated sheet is installed only on pitched roofs with slopes of at least 12%
- The overlap of adjacent sheets in a row is performed on one wave. The step of the lathing bars is 30-35 cm
- Sheets are fastened to the bottom of the wave, along the lower edge - into each wave, along the next two rows of the crate - into each odd wave, and the top is overwhelmed by the edge of the next row. For fastening, special self-tapping screws or roofing nails are used, with polymer linings.
- The overlap of the upper row on the lower row is 15-17 mm, with fastening to the crate through both sheets
If you remember these simple tricks, then the installed do-it-yourself corrugated sheet roof will last for many years, since it is a reliable and practical material.
