What Montana Homeowners Should Know About Hail Damage
Hail damage is one of the most common and expensive property insurance claims in Montana. Even hailstones as small as 1 inch in diameter can crack shingles, dent flashing, and compromise your roof's ability to protect your home.
In Montana, hail season typically runs may through august, peaking in june and july. During this window, supercell thunderstorms can produce hail ranging from pea-sized to softball-sized, often with little warning.
Signs of Hail Damage on Your Roof
- Dents or bruising on asphalt shingles (soft spots when pressed)
- Cracked or missing shingle granules exposing black substrate
- Dented gutters, downspouts, or metal flashing
- Dings on air conditioning units, vents, or siding
- Cracked window screens or damaged window trim
Filing a Hail Damage Insurance Claim in Montana
Most homeowner insurance policies in Montana cover hail damage. The statute of limitations varies, but most states allow 1 to 2 years from the date of the storm to file a claim. It's important to document damage quickly and get a professional inspection.
