How do I know if my roof has storm damage?

The Short Answer

Some storm damage is obvious, like missing shingles or fallen limbs. Much of it isn’t, such as hail bruising, cracked shingles, and lost granules. Check gutters for granules, look for dents on metal vents and gutters, and have a roofer inspect after any hail or high-wind storm.

What You'll Learn In This Article

Some storm damage is easy to spot, such as missing shingles or a tree limb on the roof. Much of it is not visible from the ground, which is why an inspection after a major storm is a good idea.

By the numbers

  • The National Weather Service counts hail 1 inch or larger as severe.
  • In IBHS research, a concentration of smaller hail (under 1 inch) knocked off more granules than a single 2-inch hailstone.
  • In the Memphis area, hail peaks in May, with 74% of reports from March through June and a secondary peak in November. Most hail falls between 4 and 8 p.m.

Signs you can check from the ground

  • Missing, lifted, or creased shingles.
  • Shingle granules collecting in gutters or at downspout outlets.
  • Dents in gutters, downspouts, vents, or metal flashing.
  • Damaged siding, window screens, or outdoor furniture after hail.
  • New water stains on ceilings or in the attic.

Damage that’s hard to see

Hail can bruise shingles and knock off the protective granules without leaving an obvious hole. Once granules are gone, the asphalt underneath is exposed to sun and weather and breaks down faster. Wind can also break the seal between shingles so they lift in the next storm. Even smaller hail can cause damage when it comes with strong wind or lasts several minutes.

What to do after a storm

Don’t climb onto the roof yourself. Take photos from the ground and schedule a roof inspection. An inspector can document any damage before you decide whether to contact your insurance company. Learn more about our storm damage services.
