Asphalt shingles are generally less blown off by the wind on the roofs of two or three-story houses.
Most commonly blown down by the wind are in the high-rise buildings above five or six stories, the roofs in the northwest or northeast direction are within one meter of the roof ridge and the surrounding cornices are more common.
The fixation method of asphalt shingles is now mainly fixed by nail glue. In winter construction, especially for single-layer asphalt shingles, due to its thin thickness, light weight and weak tear resistance, there is almost no self-adhesive glue on the asphalt shingles. In the case of its effect, it depends on the nails to fix it. If the place is blown by strong wind, it is inevitable that some exposed tiles will fall.
The asphalt shingles installed in the north are most afraid of the strong sand and dust winds in March and April. When the self-adhesive glue has not yet worked (the temperature is low and it is not sticky), if the sand is blown into the tile for the first time After the self-adhesive is soiled, the adhesion will be greatly reduced, and after repeated blows by the wind, the tiles will fall after being blown by the wind. When installing asphalt shingles in the south, the most fearful thing is the northwest wind in winter. If the self-adhesive glue does not work after installation, it is easy to blow the tiles and fall. When installing asphalt shingles in coastal areas and encountering a hurricane climate, the tiles will be blown off if the glue is not firmly adhered.
