What Does Hail Damage Look Like on Asphalt Shingles?

A hailstone strikes the asphalt shingle with significant force, compressing the fiberglass mat and dislodging the protective surface granules. This impact creates a small crater or bruise that weakens the shingle's structure and waterproofing ability. Over time, this compromised spot becomes more vulnerable to water infiltration and UV damage, making a careful, close-up inspection necessary. The size and depth of the damage can vary based on the hailstone's density and the angle of impact during the storm.

Hail damage is distinct from wind damage, which often lifts or tears shingles in a directional pattern along edges. Normal wear and aging cause uniform, overall granule loss, not isolated, pitted spots. Damage from falling branches or debris creates larger, irregular tears or punctures. A key difference is that hail bruises are often more widespread and randomly scattered across the roof's field, not concentrated on specific features like ridges or eaves. Inspecting in good light from multiple angles helps make this distinction clear.

It is wise to have a qualified roofer inspect your roof after a major storm, as they can safely assess the extent and pattern of the damage from hail or other causes. They can provide detailed documentation and photos for an insurance claim, if needed. This documentation is crucial for understanding the full scope of necessary repairs or replacement. Policies vary, and your insurer decides what is covered, so having a professional report helps clarify your situation. The roofer can also advise on the urgency and potential methods for repair versus full replacement.
