Asphalt shingles are blown off, it is basically a problem with the installation of asphalt shingles.
1. Special steel nails are not used: the nail length or diameter is not enough, and the nail cap is not big enough;
2. The bottom layer of the roof is unqualified: the tiles are not firmly fixed, and the whole tile and the steel nails are blown away;
3. The orientation of the steel nails is not nailed right: it can be judged according to the steel nail holes on the tiles that are blown away;
4. The steel nails are not nailed in: the strength of the tiles is reduced, which can be judged according to the height of the steel nails remaining on the roof;
5. Few or missing steel nails: In areas with strong wind, more steel nails are needed to enhance wind resistance, which can be judged based on the steel nail holes on the tiles that are blown away;
6. Self-adhesive barrier film leaking: It can be judged whether the tile self-adhesive barrier film has not been torn, and the tile and the tile cannot be directly adhered, which reduces the wind resistance;
7. The temperature is low during construction, and the asphalt shingle strips are not sticky: According to whether the tile strips are not adhered, the use of blowtorches is recommended for the later construction when the temperature is low.
Therefore, the installation and construction of asphalt shingles/linoleum shingles/fiberglass shingles is a very critical link. If the construction is not rigorous, it will have a great impact on the roofing system. When the customer purchases, if the construction is located in a windy area or coastal area The area must inform the salesperson, the general salesperson will suggest that the windy local customers should nail more steel nails and apply asphalt glue. If the budget is sufficient, they can purchase asphalt shingles with widened rubber to strengthen the wind resistance of the roof. The installation must be carried out according to the asphalt shingle construction manual!
