The short answer
Hail Size and Roof Damage
Hail begins to threaten a typical asphalt shingle roof at about one inch in diameter. Stones this size can knock granules off shingles and leave small dents, which may not leak right away but can shorten the roof's lifespan. As hail grows to one and a half inches, the impact force increases enough to crack older or brittle shingles.
When hail reaches two inches or more, roughly the size of a tennis ball, it can punch holes through shingles and even dent metal flashing or gutters. The angle of the storm and the wind speed matter, as a direct hit with strong wind can drive hail into vulnerable spots. If you notice missing granules or cracked shingles after a storm, a roof inspection can help you decide on repairs.
- One inch: possible granule loss and minor dents
- One and a half inches: cracked or brittle shingles
- Two inches: holes in shingles and dented flashing
- Two and a half inches: potential roof deck damage
- Three inches: may penetrate underlayment and decking
Windows and Siding Impact
Windows can break with hail as small as one inch if the glass is old, thin, or already stressed. Standard double-pane windows often survive one-inch stones but may crack with larger hail or when wind hurls the stones at an angle. Vinyl siding can also dent or crack with hail around one and a half inches, leaving your home looking worn.
Larger hail, two inches or more, can shatter windows and leave holes in siding that allow water to enter. Once water gets behind siding, it can soak into wall cavities and lead to mold growth. If you see broken glass or siding damage after a storm, consider a water damage inspection to check for hidden moisture.
When Hail Hits Skylights and Vents
Skylights are especially vulnerable because they are often made of acrylic or older glass. Hail of one inch can crack or pit these surfaces, and two-inch stones can break through completely. Roof vents and exhaust pipes can also be dented, but they rarely leak unless the seal around them is damaged.
After a hailstorm, check skylights and vent boots from the ground with binoculars if you can do so safely. Look for cracks, holes, or displaced flashing. If water has already entered, you may notice stains on the ceiling or walls, which means you should address the leak quickly to prevent further damage.
- Acrylic skylights crack with one-inch hail
- Glass skylights break with two-inch stones
- Vent boots may shift and create gaps
- Flashing around skylights can loosen
- Check from the ground for visible damage
What to Do After a Hailstorm
After a hailstorm, check your home from the ground for obvious damage like broken windows, missing shingles, or dented siding. If you have a two-story home, use binoculars to inspect the roof line. Look for granules from asphalt shingles in the gutters, as that can signal hail damage.
If you find leaks or suspect water has entered, act quickly to dry the area and prevent mold. Move furniture away from wet spots and place a bucket under a drip. For a thorough assessment, a water damage inspection can identify hidden moisture and help you understand the extent of the damage.
Does Home Insurance Cover Hail Damage?
Most standard homeowners policies cover hail damage to the structure of your home, including the roof, siding, and windows. However, you should check your policy to see if there are separate deductibles for wind and hail, which are common in some areas. Policies vary, and your insurer decides what is covered.
If you file a claim, document the damage with photos and keep receipts for any temporary repairs you make, like tarping a broken window. Your insurance company may send an adjuster to assess the loss. For help with water damage that follows hail, a restoration professional can assist with drying and repairs.

Can small hail damage my roof?
Yes, even pea-sized hail can cause minor granule loss on older shingles, but it rarely leads to leaks. One-inch hail is the threshold for noticeable dents. If you have a newer roof, it may withstand small hail without visible damage.
How can I tell if hail damaged my roof?
Look for missing shingles, dents in gutters, or granules in the downspouts. From the ground, use binoculars to spot cracked or lifted shingles. If you suspect damage, a professional roof inspection can confirm it.
What should I do if hail breaks a window?
Cover the opening with a tarp or plywood to keep water out until repairs are made. Remove any wet items from the area and dry it thoroughly. Then contact a local water damage pro to assess and dry any affected walls or floors.
