- High Winds.
If the shingles are blowing off right after you've just had the roof replaced, it probably means the seal strips haven't had the time to set, and can’t withstand the high winds. The setting process of the seal strips will vary in duration depending on weather conditions, sun exposure, and the quality of the shingles. If the shingle blow-off has to do with a faulty seal, your local contractor should replace the missing shingles free of charge.
- Poor Installation.
Another common cause of shingles blowing off of your roof is improper installation. Usually, this is the result of nailing the shingle on a higher point rather than the nailing strip across, causing the shingle to be ripped from the nail. Again, if the problem was caused during the installation, your local roofing contractor should have the missing shingles replaced free of charge.
- Storm Damage.
When dealing with shingles blow-off, it is entirely possible your roof may have underlying storm damages you haven't detected yet. For example, there could be minor-to-medium water damage. Therefore, setting the shingles under these conditions may prove unsuccessful and will get blown off. If this happens, you need to contact a professional roofing contractor to perform the necessary repairs.
- Old Age.
Depending on the quality of the materials, and the care it receives, an asphalt roof should last between 10 and 15 years. If your roof is near the end of its useful life, the seals can no longer hold the shingles in place. Consider requesting a roof replacement from your local roofing contractor.
