Roof Repair and Replacement in Big Sky
Big Sky homes sit more than a mile high, from Meadow Village up to Mountain Village. Winters are long, snow sits on roofs for months, and the summer sun at that altitude is hard on roofing materials. Whether your roof needs a repair or a full replacement starts with a free inspection that shows which makes sense.
Pictured: new shingles we installed on a Big Sky home in 2026. What a Big Sky roof has to handle:
- Heavy snow and ice dams: meltwater needs clear valleys, gutters and drains to run off instead of backing up under the shingles.
- Freeze-thaw cycles: months of daytime thawing and overnight refreezing work on flashing, seams and any weak spot.
- High-altitude sun: strong UV ages roofing materials faster than at lower elevations.
- Wildfire exposure: many Big Sky homes sit in or beside forest, which makes fire-rated roofing worth considering.
- Storms and hail: we repair storm and hail damage and help you through the insurance claim.
A Malarkey Legacy Roof Completed in Big Sky
This log-and-stone mountain home in Big Sky now has Malarkey Legacy shingles in Weathered Wood. Our crew installed new underlayment and shingles while working around the timber walls, decks and stone chimney that make Big Sky homes distinctive.
Ace Roofing is a Malarkey Emerald Premium Contractor, one of only three GAF Master Elite Contractors in the greater Bozeman area, and the only Owens Corning Platinum Preferred Contractor within 100 miles of Bozeman. Those certifications let us offer manufacturers’ premium warranties on the roofs we install.
Roofing Materials for Your Big Sky Property
Most Big Sky roofs come down to four families of material. Each has a place; the right one depends on the look you want, your budget and your lot. See every product we install on our roofing products page.
Asphalt shingles
Architectural shingles from Owens Corning, GAF and Malarkey are durable and the most affordable option, and asphalt shingle roof systems typically carry a Class A fire rating. Malarkey Legacy, used on the Big Sky home above, is one of them.
Synthetic shake and slate
DaVinci and Brava composite shakes give the rustic look of cedar or the line of slate without the upkeep of wood. DaVinci roofs last 40 to 50 years with minimal maintenance. That makes them a natural choice when a Big Sky owner wants to replace aging cedar but keep its character.
Natural cedar shakes
Real cedar suits many mountain homes and is available fire-treated. It needs more care over its life than the alternatives, which is why many owners weigh it against synthetic shake.
Metal
Metal roofing sheds snow readily and lasts a long time. It costs more than asphalt and changes the look of a home, so it is worth seeing examples before deciding.
We also install seamless 5-inch and 6-inch K-style gutters, made on our own gutter machine, and LP siding and Evolved Stone.
Commercial Roofing and Winter Roof Care
For apartment complexes and other commercial buildings, we install, repair and replace TPO, EPDM, PVC, metal and asphalt roofing, flat or sloped. Near Big Sky, we roofed Summit & Sky Apartments in Gallatin Gateway with asphalt shingles and a TPO roof.
- Roof maintenance: inspections and maintenance plans that catch problems early, including pre-winter work to clear debris and keep drainage flowing.
- Commercial rooftop snow and ice dam removal: for commercial properties, we also remove rooftop snow and ice dams during the winter.
Removing an ice dam treats the symptom; clear drainage and a sound roof are what keep meltwater moving. We will tell you which your building needs.

FAQs About Roofing in Big Sky, MT
Answers to the questions Big Sky homeowners and property managers ask us most.
No. We serve Big Sky from our Bozeman headquarters, about an hour away, and we also have an office in Wilsall. Inspections and estimates in Big Sky are free.
Yes. One example is a log-and-stone mountain home roofed with Malarkey Legacy shingles in Weathered Wood. Nearby, we roofed Summit & Sky Apartments in Gallatin Gateway.
It depends on the roof’s age, the extent of the damage and how the rest of the roof is holding up. A leak or storm damage on an otherwise sound roof can often be repaired; widespread wear usually means a repair only buys time. A free inspection tells you which applies to your roof.
Yes. Synthetic shake from DaVinci or Brava keeps the look of cedar with far less maintenance; DaVinci roofs last 40 to 50 years. Metal changes the look but sheds snow readily and lasts a long time. We also install new natural cedar, including fire-treated shakes.
For commercial properties, yes: we offer rooftop snow removal and ice dam removal. For homes, our maintenance service focuses on prevention, such as clearing debris and keeping drainage flowing before winter.
Not on its own. Ice dams form when snow melts on the roof and refreezes at the colder edge, so a new roof does not stop the cause. What a sound roof and clear drainage do is give meltwater a way off the roof and protect the home if an ice dam forms.
Yes. Asphalt shingle roof systems typically carry a Class A fire rating, the highest rating, and natural cedar shakes are available fire-treated. If your Big Sky home sits in or near forest, ask us about Class A rated options at your inspection.
Size, pitch, material and access matter most. Metal and premium synthetic products cost more than asphalt shingles, and larger, steeper or more complex mountain homes cost more to roof. A free inspection gives you an exact price, or our instant roof quote gives you an estimate in minutes.
Yes. We inspect the damage and work with your insurance company through the claim, so you are not left to manage it alone. Call us at (406) 578-2107 or contact us online.
Most residential roofs are replaced in one to three days, and up to five days for more complex projects. In Big Sky most replacements are scheduled between late spring and fall, when roofs are clear of snow, so booking early in the year gives you the best choice of dates.
