- Granules piling up in gutters
- Daylight or water stains in the attic

Common questions about roof replacement and repair in Great Falls
How much does it cost to replace a 2,000 sq ft roof in Great Falls, MT?
A 2,000 sq ft roof is about 20 squares (often 22–24 with pitch and waste). With architectural shingles, plan on roughly $6,200–$23,300 in Great Falls, MT, with most jobs near the middle of that range.
What does a new roof cost per square foot?
Architectural asphalt shingles typically run about $4.50–$12.50 per square foot installed, steel roofing about $4.50–$17 and tile about $5–$18. Roofers usually quote per square (100 sq ft).
Will insurance pay for a new roof after hail?
Usually, if hail or wind caused sudden damage and your policy covers it. You pay the deductible, which is often a percentage of dwelling coverage in storm-prone states. Normal wear and old age are not covered.
Can you put a new roof over old shingles?
Many codes allow one overlay on a single layer of asphalt shingles, but a full tear-off is usually better. It exposes rotted decking and is preferred by many manufacturers and insurers.
Do I need a roof repair or a full replacement?
Repair when damage is limited to a small area on a roof with plenty of life left. Replace when the roof is near the end of its life, has widespread curling or granule loss, or leaks in several places.
How much does a roof inspection cost?
Independent roof inspections commonly cost a few hundred dollars. Many roofers inspect free after storms, but an independent inspector has nothing to sell you.
Is a metal roof worth the cost?
For owners staying 15 years or more, often yes. Metal lasts 40–70 years and resists wind and fire, but it costs significantly more up front than shingles.
What is the best time of year to replace a roof in Great Falls, MT?
Late spring through fall works best in most climates, and fall is often the least busy season. Shingles need warm days to seal properly.
