Our Story

Ben spent years in the construction industry before starting Sisu Roofing. Along the way, he noticed something missing: too many contractors focused on getting the job done fast — not getting it done right.

He founded Sisu Roofing on a simple belief: that craftsmanship and customer care should always go hand in hand.

From the first estimate to the final inspection, we’re transparent, responsive, and respectful of your property and your time. We show up when we say we will, keep you informed every step of the way, and take pride in roofs that stand up to Montana’s toughest weather.
