Strong winds that typically accompany storms can cause shingles to crack, bend, or fly off, leaving your roof and the interior of your home vulnerable to leaks or further damage.
Hailstorms rarely last more than 15 minutes, but the damage can be devastating. Hail pounding on your roof can cause dents, missing asphalt, bruising, or cracking in your shingles.
Flat roofs without proper drainage may collect water in uneven areas, while clogged gutters can back water up under your shingles.
Depending upon the severity of the storm, debris can include anything from branches to yard furniture. It's important to remember that impact damage might not be visible from the surface of the shingle.
