You know that wind can damage your roof; strong winds can even blow off the shingles. However, this doesn't mean that your shingles should fall off the roof every time a slight wind blows. If that is happening, then there is something wrong with your roof, and you should suspect:
Dust Issues during Installation
It's not advisable to install shingles when the air is extremely dirty. The air is likely to be extremely dusty if there is a construction site next to your house, or a field is being plowed, and the land is dry. In such situations, the dust particles cling to the tar strips and prevent satisfactory sealing.
Aged shingles are also more likely to get blown off the roof than new ones. This is because the sealing power of shingles reduces with age. Not only that, but the shingles also lose their elasticity and become brittle. The combined effect of both these byproducts of aging makes the shingles weak, meaning they can easily crack and get blown off the roof.
Cold Weather Installation
Shingles should be applied in warm weather. The heat, which even a few weeks of normal sunlight can supply, softens the glue on the underside of the shingle tabs and allows them to adhere firmly to the roof. If you install your shingles during the cold season and don't heat them properly, then they will not adhere efficiently on the roof. If proper adhesion doesn't take place, then even a relatively weak wind can blow the shingles off the roof.
Just like other roofing products, shingles also come in different qualities. This may also be a reason for shingles blowing off the roof easily. For one thing, low-quality shingle tabs may not have good quality tar strips, which mean they may not adhere strongly to the roof. Aside from that, some of them also have too much filler materials, meaning they crack easily.
Ask a roofing contractor like Ziparo Brothers Construction for highly rated shingles that will stay on your roof even when the wind blows. You can even go the extra mile and request wind-resistant shingles. Some of these shingles are designed with high quality and multiline sealants to make sure they remain on the roof once they are installed.
It's advisable to inspect your roof after every storm. Be on the lookout for things like missing shingles and damaged gutters. The extent of the damage determines whether you need to call a roofer for an extensive inspection, diagnosis, and fix.
