In our area a common problem is shingle blow off. This is caused by extreme wind in some case and in others it has to do with poor workmanship. When it comes to fixing the problem, we tooth out the shingles and install new ones make sure to nail below the tar line and using the proper amount of nails.
In some areas that have super extreme winds, we will storm nail putting 6 nails in each shingles. This comes with a higher labor cost so it not for everyone.
If you experience shingle blow off we can come out in most cases and make a same day repair.
