Does homeowner's insurance cover hail damage?

How much does hail roof damage cost to repair?
It ranges widely. Minor repairs can run a few hundred dollars, while a full roof replacement on an average home often runs $8,000–$20,000+ depending on size, pitch, and material. What you actually pay depends on your deductible and whether your policy is replacement-cost or actual-cash-value.
Can I protect my roof from hail?
You can't stop hail, but impact-resistant (Class 4) shingles hold up far better than standard asphalt and often earn an insurance discount. If you're replacing a roof in a hail-prone area, they're worth pricing out.

What this means for your home
Damage can be invisible from the ground
At Great Falls's typical sizes, hail often bruises shingles and loosens granules without obvious holes, shortening roof life in ways that are easy to miss until the next storm or an inspection.
Document before you repair
If you suspect hail damage, photograph it and note the storm's date before making any repairs. Undocumented or already-fixed damage is much harder to claim later.
Replacement cost vs. actual cash value
An RCV policy pays to replace your roof at today's prices; an ACV policy subtracts depreciation for the roof's age, which can mean a much smaller check on an older roof. Knowing which you carry shapes what a hail claim is actually worth.
Get more than one estimate
After a damaging storm, reputable local roofers get busy and out-of-town crews flood in. Get multiple written estimates and verify licensing and local references before signing anything.
Keep a 'before' record
Photos of your roof and exterior in good condition make new hail damage much easier to prove later. A few shots now, before the next storm, can save an argument with an adjuster over what's old wear and what's storm damage.
Know your hail deductible
Many policies in hail-prone states use a percentage deductible, often 1–2% of the home's insured value rather than a flat dollar amount. On a $400,000 home that can be $4,000–$8,000 out of pocket before coverage starts, so it's worth checking your declarations page before a storm.
