The roof is the most important part of any building. After all, it protects us from snow, rain and other atmospheric phenomena. What will happen to the premises inside, how often you will have to repair the repair directly depends on the quality of the roof. And if you want the roof to serve you for a long time and reliably, then for its construction you need to choose the highest quality materials.
The purchase of high -quality materials initially will help you save on a possible repair. The quality of even the smallest details, such as roofing self -tapping screws, plays a huge role. Similar screws must correspond to several parameters.
The main visual difference between high -quality screws is their marking. Also, the naked eye can determine the quality of the gasket on the washer. Low -quality roofing self -tapping screws will easily separate it. The laying performs an important sealing function of the mounting site, where the screws join directly to the roofing material. After a couple of years, a poor -quality rubber washer may begin to collapse, which, in turn, leads to a violation of the tightness of the compounds. Moisture immediately begins to get into the formed connectors. From this, roofing screws are covered with rust and leaks and require immediate replacement.
High -quality screws are made of carbon steel with a coating that prevents corrosion. To replace carbon steel, a stainless steel is sometimes used, but, accordingly, the price of them also increases.
It is very easy to check the roofing self -tapping screws for quality by compressing the puck with pliers. If you have a quality product in your hands, then the paint and the rubber washer will remain completely intact, if not, then the paint will definitely begin to exfoliate, and cracks will appear on the puck.
Real self -tapping screws with a quality guarantee withstand up to 20 thousand vibrations, being at an angle of 5 degrees. This strength is enough to serve about 50 years. Thermo — and atmospheric rubber from which the washers are made, allows you to withstand large temperature changes without damage to the roof. In addition, this rubber must be resistant to various kinds of chemical influences.
Large manufacturers of metal tiles with a “name” most often supply their products complete with branded roofing self -tapping screws. Only high -quality metered products fall into these parties. There is one important factor: companies that are engaged in housing insurance and structures are unlikely to insure the object if materials were used during its construction.
