high wind affect on shingles

How High Winds Affect The Shingles of Your Northern Virginia Roof

Mother Nature is the primary cause of damaged roofs. The tearing of the shingles of your Northern Virginia roof is the most obvious result of high winds. Every shingle that is manufactured has a tolerated wind speed that it can withstand. The rating goes as follows:

Class D shingles – rated to 90 mph;
Class G shingles – rated to 120 mph; and
Class H shingles – rated to 150 mph.

The higher class shingles tend to cost more but are thicker and they can withstand higher wind speeds. These shingles are worth the cost if the roof installation is done properly because they can last up to 50 years. Vertex Roofing uses only the highest quality GAF shingles and this results in far less damage from high winds than poorer quality shingles.


When a wind storm passes through and all your shingles are still intact, don’t be too sure that they survived the storm. Very often shingles will be flapping in the wind causing folds and creases on the tops of the shingles. Additional, they are becoming weaker for the next wind storm. These folds are detected by using 2 methods. First off, they can be spotted when on the roof. They have a bold crooked horizontal crease with missing granules on it. Lastly, they can slightly be lifted to see if any resistance is intact by the sealant. If that isn’t the case, then the shingles have been damaged by the wind storm.


Whenever something is loose, it’s usually not a good thing. With the granules of shingles, it’s no different. Asphalt granules are the rocks/pebbles that are on the tops of the asphalt shingles. When high winds hit the shingles, it will cause the granules to loosen. Once the majority of the granules are loosened, your roof will begin to get exposed fiberglass. After a few rain storms, the rain will start to seep into the attic.

Vertex Roofing understands that homeowners and commercial property owners in Northern Virginia may feel getting damaged roofing shingles repaired will suffice, but in reality, it is not a smart choice. Repairing a small area of your roof only indicates that in a couple of months, you will have a similar problem in a different area, especially if the issue was caused by high winds. The best bet when you have extensive damage to the shingles of your roof after high winds is to let Vertex Roofing replace your roof with brand new GAF shingles.
