When repairs aren’t enough to protect your home, a complete roof replacement is the best way to restore long-term durability, energy efficiency, and peace of mind. At Sisu Roofing, we specialize in residential and commercial roof replacements across the Flathead Valley, combining precision craftsmanship with premium materials designed for Montana’s demanding weather.
A roof replacement isn’t just about tearing off old shingles—it’s about giving your home or building a fresh start. We begin with a comprehensive inspection to assess your existing roof’s condition, structure, and ventilation. Then, we design a replacement plan tailored to your needs, budget, and long-term performance goals.
We install a full range of roofing systems, including:
Each system is installed by certified roofers following strict manufacturer guidelines to ensure maximum warranty protection and long-term durability.
You may not need a replacement immediately—but certain signs indicate it’s time:
If any of these sound familiar, our free inspection will tell you if repair or replacement is the smarter investment.
Homeowners and business owners across the Flathead Valley choose Sisu Roofing for our combination of craftsmanship, communication, and commitment.
We’re not a traveling roofing crew — we live here, we work here, and we stand behind every project with integrity.
Whether it’s a mountain home near Whitefish or a downtown Kalispell storefront, we tailor each project to your building and your goals.
We proudly serve:
Q: How long does a roof replacement take?
A: Most residential roof replacements are completed in 1–3 days, depending on size and material type. Commercial projects may take longer based on scope.
Q: Do I need to replace the decking too?
A: Only if damage or rot is discovered during tear-off. We’ll inspect the deck thoroughly and replace sections as needed for safety and longevity.
Q: Can I upgrade my roof type during replacement?
A: Yes — many homeowners switch from asphalt to metal, tile, or other systems during replacement for improved durability and curb appeal.
Q: Will insurance cover my roof replacement?
A: If the damage was caused by a storm or sudden event, your homeowner’s policy may cover it. We’ll help you navigate documentation and adjuster requirements.
Q: What warranties do you offer?
A: We offer both manufacturer product warranties (up to 50 years) and workmanship warranties on all roof replacements.
A new roof is one of the best investments you can make for your property’s safety, performance, and value.
