Roof Damage After a Storm — What to Look For

• Dents or bruising on shingles, gutters, and flashing
• Missing, cracked, or lifted shingles
• Granule loss (dark streaks in downspouts or gutters)
• Dented or damaged skylights, vents, and AC units
• Interior water stains on ceilings or walls

Even minor hail damage can compromise your roof's waterproofing. A licensed roofer can identify hidden damage before it leads to leaks or mold.
