Roofing We Install in Helena, MT

What Montana Winters Do to a Roof
Helena averages around 40 inches of snow per year, but it's not just the volume — it's the weight and the cycles. Wet, heavy snow followed by a freeze locks ice onto your roof. That ice works its way under shingles, behind flashing, and into every gap it can find.
Most roofing failures in Montana aren't from one big storm. They're from years of freeze-thaw expanding small cracks until water gets in. By the time you see a leak on the ceiling, the damage is already done.
We install every roof with proper ice and water shield at the eaves, correctly lapped underlayment, and flashing that's done right — not just covered with caulk and hoped for the best. That's the difference between a roof that lasts and one that doesn't.
