Hail Damaged Shingles

Posted by in Hail Damage, Roof, Shingles, Weather Events | May 09, 2016

Last week we took a quick look at hand torn shingles. This week it is hail damaged shingles.

Yes, Virginia, there have been hail damaged shingles.

Hail damage to a composite asphalt shingle is commonly characterized by a small area of granule loss on the surface, but this alone is not a conclusive evidence of hail damage.  The small area of granule loss must be accompanied by a fracture, either obviously on top or on the underside (see the bottom side of the shingle in Figure 2), or a soft spot, commonly called a bruise.  A bruise on a hail damaged shingles feels similar to a bruise under the skin of an apple.

Here are a few examples of hail damage on shingles:
