Building a new home or completing a major remodel? Sisu Roofing provides expert new roof installation services throughout the Flathead Valley, delivering quality, precision, and durability you can count on. From shingle to standing seam metal and flat roofing systems, we install every roof to handle Montana’s snow, wind, and temperature extremes.
A properly installed roof protects your entire home from the elements—so getting it right from the start is critical. Our team works closely with homeowners, builders, and general contractors to ensure your new roof meets structural, energy, and aesthetic goals.
We specialize in:
Each roof is installed by certified professionals following manufacturer guidelines and Montana building codes for lasting performance and warranty protection.
Even premium roofing materials can fail if installed incorrectly. Poor fastening, misaligned panels, or bad ventilation can shorten a roof’s lifespan by years.
At Sisu Roofing, every install is done with precision and accountability—ensuring your new roof performs like new for decades.
A popular, affordable option that balances durability and curb appeal. Available in standard and architectural profiles, all rated for Montana’s snow and wind conditions.
We install both standing seam and ribbed metal systems designed for long-lasting performance and excellent energy efficiency. Metal roofs shed snow naturally and can last 40–70 years with minimal maintenance.
Ideal for garages, additions, or commercial buildings, our flat roofing systems provide watertight protection and reflectivity for improved energy savings.
We’re not a national franchise or out-of-town crew — we’re your local roofing company with a reputation for quality, honesty, and clean, professional work.
