How Hail Affects Roofing Shingles

Weather can be unpredictable, and turbulent weather—especially hail—can damage shingles.

A manufacturer’s warranty typically will not cover damage to your roof caused by hail.  Above all, review the details of the warranty covering your shingles.

Here are some answers to common questions regarding hail damage.

Hail damage is not immediately noticeable. Hail impact may cause latent damage that can, over time, result in premature aging of the shingles.

Roof shingle damage will be seen as indentations and/or fractures on the shingle’s surface. Hailstones vary in size, shape, and hardness. That will create a random pattern of dents or depressions.

What are the most common types of damage?

  • Granule loss at points of impact, which may be accompanied by surface depression.
  • Cracks in the granule-asphalt surfacing, which may radiate outward from points of impact.
  • Exposed fiberglass mat, where hail shattered the granule-asphalt surfacing causing it to break away from the fiberglass mat.
  • Fractured fiberglass mat, which may or may not be immediately visible. Ultimately, a fractured mat may result in tears radiating out from the points of impact.
  • Loosening of the self-seal strip. This damage may or may not be immediately visible and may weaken the seal integrity, creating the possibility of future shingle blow-off.

It’s possible to replace individual storm-damaged shingles. Damage to the surrounding shingles from storm damage is difficult to assess. The surrounding shingles can experience storm damage. In the end, a complete roof replacement is sometimes recommended.
