Hail Damage and Your Roof in Montana: What to Look For
Published: July 10, 2026 | Reading time: 8 min
Montana is no stranger to hailstorms. In fact, the state experiences some of the most severe hail events in the United States, particularly along the Rocky Mountain Front and across the eastern plains. Billings, located in south-central Montana, sits squarely in the path of spring and summer storms that can produce hailstones ranging from pea-sized to golf ball-sized — or even larger.
Hail damage is one of the most common reasons Montana homeowners need roof repairs or replacements. But hail damage isn't always obvious. Sometimes the damage is subtle, and without a trained eye, you might not realize your roof has been compromised until water starts leaking through your ceiling.
What Does Hail Damage Look Like on a Roof?
Hail damage can manifest differently depending on the roofing material. Here's what to look for on the most common roofing types in Montana:
Asphalt Shingles
Asphalt shingles are the most common roofing material in Billings and across Montana. Hail damage on asphalt shingles typically appears as:
- Dark spots or bruising: Impact areas where the granules have been knocked off, exposing the dark asphalt mat underneath.
- Cracks: Hailstones can crack the fiberglass mat, especially in cold weather when shingles are more brittle.
- Granule loss: Excessive granules in your gutters or downspouts after a hailstorm.
- Soft spots: Areas of the shingle that feel soft or spongy when walked on, indicating the mat has been damaged.
- Circular impact marks: Distinct round marks where hailstones struck the shingle surface.
Metal Roofing
Metal roofing is more resistant to hail damage than asphalt shingles, but it's not indestructible. Look for:
- Dents: Visible dents or dimples on the metal panels, especially on softer metals like aluminum.
- Paint damage: Chipped or scratched paint where hailstones struck, which can lead to rust over time.
- Oil canning: Wavy distortions in the metal that can be caused by large hail impacts.
Other Roof Components
Hail can also damage other parts of your roofing system:
- Gutters and downspouts: Dents, dings, and dings on gutters are often the first visible sign of a hailstorm.
- Flashing: Dented or damaged flashing around chimneys, vents, and skylights.
- Roof vents: Cracked or dented vent caps and ridge vents.
- Skylights: Cracked or shattered skylight glass or plastic.
Why Hail Damage Matters
Even small hail damage can lead to significant problems if left unaddressed. Here's why you should take hail damage seriously:
- Leaks: Damaged shingles allow water to penetrate your roof deck, leading to leaks, rot, and mold.
- Reduced lifespan: Hail damage accelerates the aging of your roof, reducing its expected lifespan by years.
- Energy loss: Damaged roofing can compromise your home's insulation and ventilation, increasing energy costs.
- Structural damage: In severe cases, water intrusion can damage the roof deck, rafters, and even the interior of your home.
What to Do After a Hailstorm in Billings
If your Billings home has been through a hailstorm, follow these steps:
- Stay safe: Don't climb on your roof immediately after a storm. Wait for conditions to improve and use a professional.
- Document visible damage: Take photos of any damage you can see from the ground, including dented gutters, downspouts, and visible roof damage.
- Check your attic: Look for signs of leaks, water stains, or daylight coming through the roof deck.
- Schedule a professional inspection: Contact Billings Roofing Co. to connect with a contractor who can perform a thorough inspection.
- File an insurance claim: If significant damage is found, your contractor can help you document the damage and file a claim with your insurance company.
Hail-Resistant Roofing Options for Montana Homes
If you're replacing your roof after hail damage, consider upgrading to impact-resistant materials. Class 4 impact-resistant shingles are the highest-rated for hail protection and can withstand hailstones up to 2 inches in diameter. Many insurance companies offer premium discounts for homes with Class 4 roofing.
Standing seam metal roofing is another excellent option for hail-prone areas. While it costs more upfront, it offers superior durability and can last 40-70 years. Read our comparison of metal vs. shingle roofs to learn more.
Does Homeowners Insurance Cover Hail Damage in Montana?
Most standard homeowners insurance policies in Montana cover hail damage to your roof. However, the specifics depend on your policy. Some policies pay actual cash value (ACV), which deducts depreciation, while others offer replacement cost value (RCV), which covers the full cost of replacement. Check your policy and talk to your insurance agent to understand your coverage.

Frequently Asked Questions About Hail Damage
How long do I have to file a hail damage claim in Montana?
In Montana, you typically have 1-2 years from the date of the storm to file a claim, depending on your policy. However, it's best to file as soon as possible to prevent further damage and ensure your claim is processed smoothly.
Can I repair just the damaged shingles instead of replacing the whole roof?
In some cases, yes. If the damage is isolated and your roof is relatively new, individual shingles can be replaced. However, if the damage is widespread or your roof is older, a full replacement may be more cost-effective and ensure uniform protection.
Will my insurance company require me to use a specific contractor?
No, your insurance company cannot require you to use a specific contractor. You have the right to choose your own roofing contractor. However, your insurance company will need to approve the scope of work and final payment.
What size hail causes roof damage?
Hailstones 1 inch (quarter-sized) or larger can cause damage to asphalt shingles. However, even smaller hail can cause damage if the shingles are old or brittle. Wind-driven hail can also cause damage at smaller sizes.
