Wind speed and roof damage: what 60-120 mph means
Translate wind speeds into roof risk, from shingle loss to structural damage.
Why gusts matter more than averages
Sustained wind tells you the baseline, but gusts drive the real roof damage.
Gusts hit edges, corners, and garage doors hardest, which can cascade into larger failures.
A short burst of 90 mph gusts can do more damage than hours of 60 mph sustained wind.
Wind bands and likely damage
These bands are general and depend on roof age, fastening, and materials. Use them as rough planning ranges.
- 60-75 mph: loose shingles, minor fascia damage, tree limb loss.
- 75-95 mph: widespread shingle loss, soffit damage, power outages.
- 95-120 mph: roof deck exposure, window failures, structural strain.
- 120+ mph: major structural risk, large debris impacts, full roof failure possible.
Roof materials and construction make a big difference
Two roofs with the same wind exposure can perform very differently.
Impact-rated shingles, sealed underlayment, and properly nailed decking often outperform older roofs at the same wind speed.
- Age and fastening schedule for shingles or tiles.
- Deck attachment and secondary water barriers.
- Roof geometry, overhangs, and garage door bracing.
- Tree coverage and nearby debris that can become projectiles.
Pressure zones and weak points
Wind pressures are highest at roof edges, corners, and ridgelines. These areas fail first and can peel back large sections.
Garage doors, gable ends, and roof-to-wall connections are common weak points in older homes.
Inspection checklist before storm season
A quick inspection and reinforcement plan can prevent the most expensive failures.
- Check for missing or brittle shingles and replace early.
- Ask about hurricane straps, roof decking nails, and edge flashing.
- Confirm your roof is rated for local wind zones.
- Document roof condition for insurance before a storm hits.
When to file a claim
If you see deck exposure, widespread shingle loss, or interior leaks, document immediately and contact your carrier.
Photos of roof edges, gutters, and interior staining can speed claims and reduce disputes.
Key takeaways
- - Gusts drive roof damage more than steady wind.
- - Roof age and fastening are the biggest performance swing factors.
- - Edges, corners, and garage doors are the first failure points.
- - Document condition before storm season for faster claims.
