Quick Answer

Wind damage to roofs shows up as lifted, creased, or missing shingles, typically along edges, ridges, and corners where wind pressure is highest. In Wisconsin, wind damage is covered by homeowner's insurance. DT Exteriors provides free wind damage inspections and handles the entire claims process with a 98% approval rate.

How Wind Actually Damages Your Roof

Wind doesn't push shingles off from above — it lifts them from below. Understanding the mechanism helps you identify damage:

The Lift Mechanism

  1. Wind flowing over your roof creates negative pressure (suction) on the surface
  2. This suction is strongest at edges, corners, ridges, and hips
  3. Shingles lift, breaking the sealant bond that holds them flat
  4. Once the seal is broken, even moderate winds can peel, crease, or tear shingles away

Wind Speed vs Damage Level

Wind SpeedTypical DamageInsurance Claim?
45-60 MPHSeal breaks on older/worn shingles, minor liftingUsually not
60-80 MPHCreased and missing shingles, damaged ridge capsYes
80-100 MPHWidespread shingle loss, exposed decking, flashing damageYes — major claim
100+ MPHStructural damage, decking separation, catastrophic lossYes — total replacement
Wisconsin Reality: The July 2019 storm system that hit Waukesha County produced straight-line winds of 80-100 MPH. It destroyed or damaged thousands of roofs in a single event. These aren't rare — they happen every 2-3 years in our area.

How to Identify Wind Damage From the Ground

You don't need to get on your roof. Here's what to look for from the ground:

  • Missing shingles — Obvious dark patches where shingles are gone
  • Shingles in your yard — Even one shingle on the ground means more are compromised above
  • Lifted or curled edges — Shingles sticking up when viewed from an angle
  • Creased shingles — Horizontal lines across shingles where wind bent them back
  • Damaged ridge caps — The shingles along the very top of the roof are most vulnerable
  • Damaged flashing — Metal pieces around chimneys, walls, or vents pulled away
  • Gutter or downspout damage — Often accompanies roof wind damage

Important: Wind damage is often not visible from the ground. A professional inspection catches what you can't see — and creates the documentation needed for an insurance claim.

Filing a Wind Damage Insurance Claim

The Right Sequence

  1. Call DT Exteriors first: (262) 945-0841 — We inspect for free and document everything with photos
  2. We help you file the claim with the proper damage documentation
  3. We meet with your adjuster to walk them through the damage on your roof
  4. If approved, we handle the repair/replacement and work directly with your insurance on payment
Why This Order Matters: Filing a claim without professional documentation often leads to underpayment or denial. Our 98% approval rate comes from thorough documentation before the adjuster ever arrives. We know what adjusters look for because we've worked with them hundreds of times.

Frequently Asked Questions

Most Wisconsin policies allow 1 year from the date of the event, but check your specific policy. We recommend filing within 30 days for the strongest claim. DT Exteriors provides time-stamped photo documentation to support your timeline.

It depends on the extent. Localized damage (a few shingles in one area) can often be repaired for $300–$1,500. Widespread damage across multiple slopes usually means replacement is more cost-effective — and your insurance typically covers it.
