How wind damages shingles and flashing
Wind pressure is strongest at roof edges, corners and ridges. It can break shingle seals, crease tabs, loosen exposed metal and force rain into small openings at flashings. The decision should also account for branches or impact marks.
Damage may be subtle
A shingle can remain in place after its seal breaks, then lift during the next storm. Creases, displaced tabs and debris below the roof are useful clues.
Edges and penetrations need attention
Rake metal, eaves, ridge caps, vents and chimney flashings experience concentrated pressure. Fastener pattern and substrate condition affect resistance.
Inspect safely after the event
Use ground-level photos and interior observations. Do not climb onto a wet roof or approach downed lines; arrange professional access when conditions stabilize.
Details worth checking
- Missing or shifted shingles
- Creased tabs
- Lifted ridge caps
