Hail Damaged Shingles (Updated)

Posted by in Hail Damage, Roof, Shingles, Weather Events | July 13, 2020

A few years ago we took a quick look at hand torn shingles and hail damaged shingles.  Here is an update to the hail damaged shingles post.

Yes, Virginia, we have found hail damage to shingles where others did not or were skeptical.

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:
