25 Roof Leak Warning Signs (With Photos) — When to Call a Roofer for Repair

Moment #17: Hail impact bruises (granule loss)

Hail damage often appears as dark bruises, scuffs, or spots with missing granules. Even small impacts can weaken shingles and make them more prone to leaks later. After hail storms, check slopes facing the storm direction and look for consistent damage patterns. If granules are missing and asphalt is exposed, deterioration accelerates. This is a common reason homeowners schedule inspections soon after severe weather.
