Roofing Services in Kalispell, MT

Roofing in Kalispell is most of what we do, and our shop is close enough that we treat the city as home turf. Sisu Roofing is based on Browns Meadow Road in Kila, a short run up US Highway 2 from the west side of town, and Kalispell is where the bulk of our estimates, tear-offs, and repairs happen. We replace asphalt shingle roofs, install standing seam metal, and maintain flat and low-slope roofs on commercial buildings, all with the same process: owner Ben Wuollet keeps the operation small enough to check the work, every estimate starts with a drone survey of your actual roof, and we install to the specs that keep our Malarkey Certified Installer and Owens Corning Preferred Contractor standings intact.

Kalispell housing stock, from the East Side Historic District to Silverbrook

Kalispell has one of the widest spreads of roof types in the valley because the city grew in distinct waves. The East Side Historic District holds Queen Anne, Colonial Revival, Foursquare, and Craftsman homes built between the 1890s and the 1920s, in the blocks around Woodland Park and the Conrad Mansion. Those roofs are a different job than anything in a new subdivision: cut-up rooflines, steep pitches, plank decking instead of plywood, and sometimes two or three old shingle layers that all have to come off before we can evaluate what is underneath. Mid-century neighborhoods west and south of downtown tend toward simpler gable and hip roofs where a straightforward tear-off and reshingle makes sense. Then there is the new construction ring: Silverbrook Estates north of town off US 93 near the Stillwater River, Westside Estates on the city's western edge, and the infill that has followed the bypass. Those homes have modern decking and ventilation but were often roofed with builder-grade shingles, and many are reaching the age where hail strikes and granule loss start showing up on a drone survey. We bid each of these situations differently because they are different jobs.

What valley-floor weather does to Kalispell roofs

Kalispell sits on the Flathead Valley floor, which spares it the deepest mountain snow but trades that for a long freeze-thaw season. Snow lands on your roof, melts against warm attic air, refreezes at the cold eaves, and builds the ice dams that push water backward under shingles. Most of the active leaks we chase in Kalispell in late winter trace back to that cycle plus thin or missing ice and water barrier at the eaves and valleys. Summer brings convective storms off the mountains with hail and gusty wind, which is why impact-rated shingles have become our default recommendation here rather than an upgrade pitch. The drone survey matters in this climate because valley damage is often subtle: bruised shingles, lifted tabs on the windward slopes, and flashing gaps you cannot see from a ladder. We photograph all of it and walk you through the images before we talk about scope.

Shingle, metal, and commercial flat work across Kalispell

The three big product decisions in Kalispell each get their own dedicated page on this site, but the short version is this. Asphalt shingle roofing is still the right call for most Kalispell homes; we install Malarkey polymer-modified shingles because the rubberized asphalt handles hail and cold-weather flexing better than standard product, and installing them correctly is what our certification is based on. Standing seam metal roofing costs more up front and earns it back on steep pitches, on homes surrounded by trees, and for owners who want to stop thinking about their roof; it sheds snow instead of holding it. Commercial flat and low-slope roofing covers the shops, offices, and retail buildings along the US 2 and US 93 corridors, where we handle EPDM, coatings, and the drainage details that decide whether a flat roof quietly works or quietly ponds. If you are weighing two of these options against each other, say so at the estimate and we will price both from the same drone survey.

Kalispell is the busiest roofing market in the Flathead Valley and the center of our service area; the surrounding city pages on this site all connect back to the same crew and process described here.

Our shop sits on Browns Meadow Road in Kila, about fifteen minutes from downtown Kalispell on US Highway 2.

What we do in Kalispell

Kalispell questions we actually get

How fast can you look at a leak in Kalispell?

Usually quickly. Our shop in Kila is about fifteen minutes from downtown Kalispell on US 2, and because most of our active jobs are in or around the city, we can often swing a truck by the same day or the next morning. For active leaks we stabilize first, then schedule the permanent repair once we have drone photos of the whole roof.

Is metal roofing worth it on a Kalispell home?

It depends on the house more than the town. On steep pitches, on homes shaded by big trees where shingles stay damp, and for owners planning to stay put for decades, standing seam metal is a strong buy. On a simple one-story gable roof with good sun exposure, a quality impact-rated shingle does the job for a lot less. We install both, so we have no reason to push you either way; ask for both numbers at the estimate.

Can you work on the older homes near Woodland Park and the East Side?

Yes, and we bid them as what they are: complex roofs on hundred-year-old framing. That usually means budgeting for deck repair once the old layers come off, matching flashing details to original masonry chimneys, and getting ventilation into attics that were never built with it. The drone survey plus an attic look tells us most of what we need before we quote.

Do you handle commercial and flat roofs in Kalispell?

Yes. We maintain, coat, and replace flat and low-slope roofs on commercial buildings around Kalispell, including EPDM membrane work. Flat roofs fail at penetrations, seams, and drains far more often than in the field of the roof, so our commercial inspections focus there.

What does the drone survey actually show me?

High-resolution photos of every slope, ridge, valley, and flashing on your roof, taken the day we visit. You see what we see: hail bruising, cracked or lifted shingles, rusted flashing, granule loss in the gutters. It also means nobody has to walk your roof to bid it, which matters on steep or fragile surfaces.

Kalispell and Flathead Valley homeowners, in their own words.

Ben and his team provided excellent communication and service. They were in and out and a couple of days tearing off and replacing a steep roof. We will use them again for future roofing needs on our homes.

Kyle with Sisu Roofing was great! He was very responsive and even put a temporary patched on my roof for free! He was also upfront and honest about cost too. Would highly recommend working with Kyle and Sisu.
