Gutter Installation in Idaho

Local know-how

Gutters and gutter guards in Idaho

Idaho’s fast growth, especially in the Treasure Valley, means many newer homes that came with minimal gutters. Snowmelt and spring rain make full seamless systems a worthwhile upgrade.

In northern Idaho and mountain areas, heavy snow calls for strong hangers and sometimes roof snow guards. Conifers drop needles, so micro-mesh guards are popular.

Pocatello, Idaho Falls and eastern Idaho see cold winters and snow, so heavier-gauge gutters and close hanger spacing are common recommendations there.

Two very different climates

Boise averages about 11.5 inches of precipitation and about 18 inches of snow a year under NOAA’s 1991–2020 normals, with most precipitation from late fall through spring and very dry summers. North Idaho, around Coeur d’Alene and Sandpoint, and mountain towns such as McCall, Ketchum and Driggs, are much wetter and snowier. Gutters in the Treasure Valley mostly handle winter rain and snowmelt; in the north and the mountains, snow load and ice dams dominate.

Snow load and ice dams

Heavy snow and freeze-thaw cycles bring ice dams to homes with limited attic insulation, and ice and sliding snow can pull gutters loose. Insulation, ventilation and ice and water shield at the eaves address the cause; heavier gauge and hidden hangers at close spacing keep gutters on. On metal roofs, snow guards hold snow so it melts gradually. See ice dams and gutters, snow load and gutters and snow guards explained.

Pines and firs

Ponderosa pines, Douglas firs and other conifers surround many Idaho homes. Needles slip through coarse screens; fine-mesh metal guards keep them out better. Cottonwoods along the Boise River and other streams add fluff and seeds in spring. See gutter guards for pine needles vs. leaves.

Wildfire embers

Much of Idaho is fire country, and homes near the foothills and forests face ember exposure. Dry needles in gutters can ignite. Metal gutters, metal guards and keeping roofs and gutters clear reduce that risk. See gutters and wildfire embers.

Foothills, slopes and basements

Homes in the Boise foothills, Eagle and other hillside areas often have basements and retaining walls. Carry roof water to the downhill side and release it where it will not undercut walls or flow toward neighbors. Buried lines must drain so they do not freeze. See underground downspout drainage.

Fast growth

The Treasure Valley is among the fastest-growing areas in the country, and many new homes have builder-grade 5-inch gutters and few downspouts on large roofs with valleys. Adding downspouts or upgrading to 6-inch gutters fixes most overflow at inside corners. See roof valleys and gutter overflow.

Idaho contractor registration

Idaho requires contractors to register with the Idaho Contractors Board for projects over $2,000, including labor and materials. Registration requires proof of general liability insurance and workers’ compensation or an exemption, but it is not a skills license. Ask for the registration number and verify it, along with insurance and a written contract.

Costs and choices

HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally. In Idaho, heavier gauge and close hanger spacing for snow, fine-mesh metal guards under conifers, snow guards on metal roofs and drainage plans for sloped lots are the main choices. See our cost guide.

Choosing an installer in Idaho

Before you sign, verify the company’s Idaho Contractors Board registration, 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 whether proposed guards will shed snow in winter and how gutters will be protected from sliding snow. See how to choose a gutter contractor.

Spring runoff and basements

In late winter and spring, snow on roofs and yards melts while the ground below is still frozen, so meltwater cannot soak in. It runs toward the lowest point, often a basement wall or window well. Downspouts that carry water well away from the house matter most at exactly that time of year. Extensions that are removed for mowing in summer should be back in place by fall, and buried lines should be checked for ice or blockages before the thaw. Window wells near downspouts should have covers or drains. See wet basement? check gutters first and downspouts and your foundation.
