Damage To Shingles Caused by Hail
Is Damage Immediately Noticeable?
Not always... hail impact may cause gradual loss of granules that can, over time, result in premature aging of the shingles.
Without visual damage, there is no real way to be sure how much damage shingles have encountered. Outward damage may not be apparent until months or years later.
How Can I tell If the Roof Was Damaged?
Generally, damage can be see as indentations and/or fractures in the shingle surface. Hailstones vary in size, shape, and hardness and can create a random pattern of dents or depressions. If this is not evident, look for indentations on metal flashings, siding, chimney caps, or even skylight flashings. After some time, clusters of granules may come off (at the point of impact) in a random pattern and expose the asphalt.
