Identifying Wind Damage — StormBuddy Academy

How wind damages a roof

Wind lifts shingle edges, breaks the sealant bond, and folds the shingle back. Once a seal is broken, the shingle keeps flapping and eventually creases or tears off.

Wind damage: missing shingles, exposed underlayment and lifted tabs near the ridge.

Creased shingles: A horizontal crease line across the tab, usually near the nail line. Creased shingles are damaged even if still in place.
Broken seal strips: Shingles lift easily by hand with clean, non-tacky sealant. Document with a gentle lift test.
Missing shingles / tabs: Exposed underlayment or nail heads. Check the yard for debris.
Ridge and edge loss: Ridge cap, rakes and eaves fail first since wind pressure peaks there.

Tell the story

Wind damage is directional. Match the damaged slopes to the reported wind direction from storm data. Photograph creases with light raking across them so the line shows clearly.
