Gutter Installation in Montana

Local know-how

Gutters and gutter guards in Montana

Montana’s snow and wind require strong gutter attachment. Heavy-duty seamless gutters with close hanger spacing are recommended, and snow guards on metal roofs protect gutters from sliding snow.

Growing towns like Bozeman see many new homes, while many older homes in Billings need their original gutters replaced.

Popular upgrades include heavier-gauge seamless gutters, closely spaced hidden hangers, and downspouts routed so meltwater does not freeze on walkways and driveways.

Key facts: gutters in Montana

• Typical cost: HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally; local prices vary.
• Do gutter installers need to register in Montana? Construction contractors with employees need a Department of Labor and Industry registration; those without employees can use an independent contractor exemption certificate.
• How much snow does Billings get? Roughly 57 inches a year on average, with about 14.3 inches of total precipitation under the 1991–2020 normals.
• Common choice: seamless aluminum K-style gutters in 5- or 6-inch sizes; 6-inch with 3x4-inch downspouts for large roofs and heavy rain.
• How to get connected: call the number on this page and you are connected with an independent local installer who serves your ZIP code. The call is free and there is no obligation.

Dry, cold and snowy

Billings averages about 14.3 inches of precipitation and roughly 57 inches of snow a year under NOAA’s 1991–2020 normals. Western Montana valleys such as Missoula and Kalispell are wetter in winter, and mountain towns get far more snow. Most of the state’s precipitation comes as spring rain and winter snow; summers are dry, with thunderstorms. In Montana, gutters are tested mostly by snow, ice and meltwater.

Chinooks and freeze-thaw

East of the Rockies, chinook winds can raise temperatures dramatically in hours, melting snow on roofs that then refreezes when the cold returns. Those swings create ice dams and ice-filled gutters. Insulation, ventilation and ice and water shield at the eaves address the cause; heavier-gauge gutters with hidden hangers at close spacing hold up better. See ice dams and gutters and snow load and gutters.

Metal roofs and snow guards

Metal roofs are common in Montana and shed snow suddenly. Snow guards hold snow so it melts gradually, and gutters are set so sliding snow clears them. See snow guards explained and gutters for metal roofs.

Hail and wind

Eastern and central Montana see hailstorms in late spring and summer, and strong winds across the plains. Heavier-gauge aluminum resists dents; hidden hangers, strapped downspouts and guards that fasten down keep gutters on the house. See hail-damaged gutters and gutters and high winds.

Wildfire embers

Western Montana and many forested communities face wildfire risk. Embers can ignite dry needles in gutters. Metal gutters, metal guards and keeping roofs and gutters clear reduce that risk. See gutters and wildfire embers.

Log homes and cabins

Log homes and cabins are common in Montana. Gutters keep roof water off log walls and away from the bottom courses, which are most prone to rot; wide overhangs alone do not protect the base. See gutters for log homes and cabins.

Montana contractor registration

Montana’s Department of Labor and Industry requires construction contractors with employees to hold a construction contractor registration, while contractors without employees can work under an independent contractor exemption certificate. The department offers online searches for both. Registration is tied to workers’ compensation and is not a skills license, so ask any installer for insurance and a written contract, and check local business licenses where required.

Costs and choices

HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally. In Montana, heavier gauge and close hanger spacing for snow and ice, snow guards on metal roofs, metal guards in wildfire areas and drainage that works in freezing weather are the main choices. See our cost guide.

Choosing an installer in Montana

Check the company’s registration or exemption certificate with the Department of Labor and Industry, ask for a certificate of insurance sent directly by the insurer and get a written contract that lists gutter size and gauge, hanger type and spacing, downspout size and discharge points, and how fascia repairs will be priced. Ask how the gutters will be protected from sliding snow and ice. See how to choose a gutter contractor.

Spring runoff and basements

When snow on roofs and yards melts while the ground is still frozen, meltwater cannot soak in and runs toward the lowest point, often a basement wall or window well. Downspouts that carry water well away from the house matter most at that time of year. Extensions removed in summer should be back in place by fall, and buried lines should be checked before the thaw. See downspouts and your foundation.

Ranches, shops and outbuildings

Across Montana, homes often share the property with shops, barns, garages and equipment sheds. Gutters on outbuildings keep water away from doors, concrete aprons and stored equipment, and they reduce ice at entrances in winter. Doing the house and outbuildings in one visit usually costs less than separate jobs. See gutters for garages, sheds and outbuildings.
