Roof Shingle Blow Off

Do you have missing shingles which have blown off your roof?

“How do winds cause shingle blow off?”

There are several causes of shingle blow off (aka roof blow-off):

1) Incorrect installation … usually caused by improper placement of the nails securing the singles.

2) Too much air-pressure from the nail gun sinking the nail too far in causing the shingle to tear making it insecure. (This can also eventually cause roof leaks.)

3) Missing shingles can also be due to the seal failure of the shingle.

4) Shingle blow off can be caused by severe Denver Colorado winds which exceed the manufacture rating of the roof shingle.

When Global Roofing finds a roof which has a few shingles missing, and there haven’t been damaging winds over 60 mph, we usually replace the missing and damaged shingles.

We carefully remove the damaged shingles still remaining, then we reinstall new shingles matching the color and style as closely as possible, and properly nailing them per manufacturer’s specifications.

Next, we apply roof cement between the layers of shingle to insure that the old shingles bond with the new shingles.

(Of course, we thoroughly clean up any job related debris when the repair is completed.)

Shingle wind damage

One caveat about roofs which have sustained this type of damage. Even more roof shingles may blow off in other areas of your roof in the future. Unfortunately, there is no accurate way to predict or prevent this or to determine whether or not it will even occur.

Your best bet is if you’ve had two instances or more of shingle blow off on your roof, consider full roof replacement.

With Colorado’s winds, it’s a necessary “evil” to get your roof thoroughly inspected for wind damage every year. If it needs replacement, it will be covered as a loss on your homeowners insurance.

Remember to occasionally look at every section of your roof. Missing shingles may not cause a roof leak right away, but it will eventually because the roof felt will deteriorate.

Also, why not do your neighbor a favor if you see some missing shingles on their house, and let them know? Sections of their roof may be more visible from your property than theirs, whereas they can’t see the damage. They will thank you.

Global Roofing does both one-day roof repair and roof replacement, and we specialize in getting insurance claims approved where other roofers couldn’t.
