The short answer
Wind Speed Thresholds
Wind speeds of 40 to 50 mph can lift loose shingles, especially on older roofs or those with poor adhesion. At 60 mph, you may see significant shingle loss, and 75 mph or higher can cause structural damage to the roof deck. These numbers are general guidelines, not a certainty of what will happen to your specific roof.
Your roof's condition plays a big role. A well-maintained roof with proper fastening might withstand stronger gusts, while a weathered roof can fail at lower speeds. Wind direction and sudden gusts also matter more than the average wind speed, so pay attention to the highest gusts in a storm.
- 40 to 50 mph: possible shingle lift or curling
- 50 to 60 mph: shingle loss in vulnerable areas
- 60 to 75 mph: widespread shingle damage
- 75 mph and above: risk of deck or structural damage
- Gusts are more damaging than steady winds
- Roof age and condition lower the threshold
How Wind Damages Roofs
Wind doesn't just blow shingles off; it creates uplift pressure that can loosen fasteners and lift edges. Once air gets under a shingle, the force increases and can tear it away. This often happens at eaves, ridges, and corners where wind pressure is highest.
Flying debris, like branches or loose objects, can also impact the roof and cause punctures or granule loss. Even if the roof looks fine after a storm, hidden damage may allow water to seep in later. Checking for missing shingles, exposed nail heads, or granules in gutters helps you spot early signs.
- Uplift pressure loosens fasteners
- Edges and corners are most vulnerable
- Flying debris can puncture the surface
- Granule loss accelerates weathering
- Hidden damage may not be visible from the ground
Signs of Wind Damage
After a strong wind event, walk around your home and look for obvious signs like missing, cracked, or lifted shingles. Check for exposed underlayment or nail heads, and inspect gutters for an unusual amount of granules, which indicates shingle wear. Also look for dents or tears from debris.
Inside your home, watch for water stains on ceilings or walls, especially in the attic. If you suspect damage, you can do a simple check from the ground with binoculars, but don't climb onto the roof yourself if it's steep or wet. A professional inspection is safer and more thorough.
What to Do After a Storm
If high winds hit your area, start by documenting any visible damage with photos and notes. This helps with your insurance claim, but remember that policies vary, and your insurer decides what is covered. Contact your insurance company to report the damage and ask about next steps.
For immediate protection, you can place a tarp over a damaged roof if it's safe to do so, but avoid walking on a slippery or steep roof. If the damage is extensive, a professional may be needed to tarp the roof temporarily. Always prioritize your safety and the safety of others.
- Take photos of all visible damage
- Document the date and time of the storm
- Check attic for leaks or water stains
- Tarp a damaged area only if safe
- Contact your insurer promptly
- Avoid climbing on the roof yourself
When to Call the Pros
Not every roof issue is an emergency, but if you see missing shingles, exposed underlayment, or water stains inside, it's time to call for help. The pros can assess the extent of the damage and recommend repairs. They can also check for hidden issues that you might miss.
If water has already entered your home, you need water damage cleanup to prevent mold and structural problems. The pros have the right equipment to dry out affected areas and restore your home. Acting quickly can minimize the damage and reduce the risk of long-term issues.
- Visible shingle loss or damage
- Water stains on ceilings or walls
- Leaks in the attic after rain
- Sagging or soft spots on the roof
- Debris impact or punctures

Can 40 mph winds damage a roof?
Yes, 40 mph winds can lift and curl shingles, especially on older or poorly installed roofs. They can also blow debris that impacts the roof. If your roof has pre-existing weaknesses, even moderate winds can cause damage.
What wind speed tears off shingles?
Shingles often start tearing off at wind speeds around 60 mph, but this depends on the shingle quality and how well they are fastened. Gusts above 70 mph can cause more extensive loss, and older shingles may fail at lower speeds.
Should I get my roof inspected after a windstorm?
If the wind was strong enough to cause visible damage, it's a good idea to have a professional inspection. Even if you don't see issues, hidden damage can lead to leaks later. An inspection can catch problems early and help with insurance claims.
