Wind damage to roofs: what to look for

By Roof InspectorsUpdated 3 min read

The short answer

Wind damages roofs by lifting shingles and breaking the seal that holds them flat, which can crease, tear, or remove them — usually starting at edges, corners, and ridges. Gusts of 58 mph or more meet the National Weather Service severe threshold, but older or poorly sealed shingles can be damaged by lower speeds.

Hail gets the headlines, but wind quietly damages plenty of Kansas City roofs, especially during spring and summer thunderstorms. Weather Service records show more days with damaging-wind reports than large-hail reports across the metro; see the storm record for Kansas City, Missouri.

How wind damages a roof

Asphalt shingles are held down by nails and a strip of sealant that bonds each shingle to the one below. Strong gusts can:

  • Lift a shingle and break its seal, letting wind get under it more easily next time
  • Crease a shingle as it bends back, creating a weak line that can crack or let water in
  • Tear off shingles, ridge caps, or pieces of flashing
  • Drive debris like branches into the roof

Damage usually starts where wind pressure is highest: edges, corners, ridges, and rakes.

Which wind speeds matter

The National Weather Service considers gusts of 58 mph or more severe. At those speeds, lifted and creased shingles become more common. Gusts of 74 mph or more (hurricane force) often remove shingles.

But speed isn’t everything. Older shingles that have lost flexibility, shingles that never sealed properly, and roofs with installation shortcuts can be damaged by lower speeds.

What to look for from the ground

  • Missing shingles or shingle pieces in the yard
  • Shingles that look raised, wavy, or out of line
  • Exposed nail heads or bare spots
  • Missing ridge caps
  • Damaged flashing around chimneys or walls

Use binoculars if you have them — and please stay off the roof.

Why creased shingles matter

A creased shingle may lay flat again and look fine from the ground. But the crease weakens it, and the broken seal makes it more likely to lift in the next storm. Professionals check for this by examining shingles up close, often gently lifting edges to check the seal.

When to get an inspection

If storm records show gusts of 58 mph or more near your home, or you notice any of the signs above, a professional roof inspection can confirm whether there’s damage that needs attention. See how many significant storms are on record near your address, free in about 30 seconds.

Common questions

How much wind can a shingle roof withstand?
It depends on the shingle’s wind rating and how it was installed. Shingles are rated under two lab tests: ASTM D3161 classes stand for 60, 90 or 110 mph, and ASTM D7158 classes for basic wind speeds of 115, 150 or 190 mph, according to the National Roofing Contractors Association. Ratings assume the shingles were installed to the maker’s specifications, and aging, poor sealing, or installation shortcuts lower real-world resistance.
Can wind damage be hidden?
Yes. A shingle can lift, break its seal, and lay back down looking normal. Creases and broken seals are often only visible up close.
