What does hail damage look like on a roof?
On asphalt shingles, hail damage often looks like dark spots where the granules have been knocked off, scattered across the roof with no pattern. The shingle underneath may feel soft. Hail damage does not always cause a leak right away, so a roof can be damaged even when you see no signs of it inside your home.
How hail damages shingles
Asphalt shingles have a layer of granules on top that protects them from the sun. When hail hits hard enough, it can knock the granules loose and crack the shingle underneath.
The roof may not leak right away. Over time, the damaged areas wear out faster, and leaks can show up months or years after the storm.
That is why it is a good idea to have your roof inspected after a hail storm, even if you do not see a leak.
Signs of hail you can check from the ground
Metal parts of your home show hail damage more clearly than shingles do. Look for dents in your gutters, downspouts, window screens and any roof vents you can see.
Dents in these areas mean hail hit your home, which is a good reason to have the roof checked as well.
Please do not climb onto your roof to look for damage. Walking on a damaged roof can make the damage worse, and falls are a serious risk.
Wind damage
Strong wind can lift shingles and break the adhesive strip that holds them down. The shingles may lie flat again and look normal from the ground.
Shingles with a broken seal are loose and more likely to blow off in the next storm. Finding this kind of damage requires a close inspection on the roof.
Storm damage and insurance
Homeowners insurance policies have deadlines for reporting storm damage, often counted from the date of the storm. Check your policy so you know how long you have.
Having your roof inspected soon after a storm makes it easier to document the damage and connect it to a specific storm date.

How big does hail have to be to damage a roof?
Hail around one inch in diameter or larger can damage asphalt shingles. Wind speed and the age of the roof also play a part, and smaller hail can still dent gutters and vents.
Can I check for hail damage myself?
You can check your gutters, downspouts, window screens and vents from the ground. Leave the roof itself to a professional.
My neighbor is getting a new roof. Does that mean I need one?
Not necessarily. Hail can hit one house harder than the house next door. It is still a good reason to have your roof inspected.
