Gutter Installation in Wisconsin

Local know-how

Gutters and gutter guards in Wisconsin

Wisconsin winters bring heavy snow and ice. Seamless gutters with hidden hangers and oversized downspouts are standard.

Madison and Green Bay neighborhoods have mature trees, making guards popular. Summer storms test downspout capacity.

In Madison, Green Bay and Appleton, heavy-duty seamless gutters with hidden hangers stand up to snow, and guards keep leaves out before winter.

Snow from 30 to more than 150 inches

According to the Wisconsin State Climatology Office, the statewide average snowfall is slightly more than 56 inches a season, ranging from about 30 inches in the southern counties to more than 150 inches in the lake-effect snow belt just south of Lake Superior. Milwaukee averages about 34.6 inches of precipitation and about 48.7 inches of snow a year under the 1991–2020 normals. Summers bring thunderstorms and heavy rain, with June typically the wettest month in Milwaukee.

That means Wisconsin gutters spend months under snow and ice, then handle snowmelt and summer downpours. See snow load and gutters.

Ice dams and older homes

Milwaukee bungalows and Polish flats, Madison’s older neighborhoods and homes across the state have steep roofs and limited attic insulation. Ice dams pull gutters loose and back water under shingles. Hidden hangers about every 2 feet into rafter tails, heavier-gauge gutters and attic air sealing help. Some older homes still have built-in box gutters that leak into walls when linings fail. See ice dams and gutters and box gutters on old homes.

Downspout disconnection in Milwaukee

In Milwaukee’s combined sewer area, MMSD’s rules require disconnection of downspouts at residential properties of four units or less where it can meet the city’s plumbing code and MMSD criteria. The city’s Downspout Disconnection Program explains how: the downspout is cut above the standpipe, an elbow and extension send water onto a lawn or garden, and the standpipe is capped. See disconnecting downspouts.

Basements and clay soils

Most Wisconsin homes have basements, and clay-rich soils drain slowly. Roof water at the foundation is a common cause of wet basements, especially when snowmelt and spring rain arrive together and extensions are buried by snow. See wet basement? check your gutters first.

Northwoods cabins and the lakeshore

Cabins and homes in the Northwoods and along Lake Superior and Lake Michigan face heavy snow and sit under pines and hardwoods. Metal roofs shed snow that can tear gutters off; snow guards, strong hangers and fine-mesh metal guards help. See gutters for log homes and cabins.

Madison, the Fox Valley and the Driftless

Madison’s older neighborhoods around the isthmus have early 20th-century homes with steep roofs and mature trees, while the hilly Driftless Area in southwestern Wisconsin has homes on slopes where roof water should be piped away from foundations. Green Bay and the Fox Valley see colder winters and plenty of snow. Across the state, planning for snow load and spring melt comes first. See underground downspout drainage.

Wisconsin contractor rules

Wisconsin requires a Dwelling Contractor credential, with a qualifier who has completed approved training, for businesses doing work on one- and two-family homes that requires a building permit. Gutter-only work often does not need a permit, but roofing and some exterior projects do, and municipalities may have their own rules. Ask the installer about credentials and permits, proof of insurance and a written contract.

Costs and choices

HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally. In Wisconsin, prioritize close hanger spacing, heavier gauge, snow-friendly guards and downspouts that meet disconnection rules and keep water away from basements. Late summer and early fall are the best time to schedule replacement. See our cost guide.

Heat cables and problem spots

On north-facing eaves, valley corners and over entries, ice builds fastest. Heat cables in gutters and downspouts can keep a drainage path open on these problem spots, used together with attic air sealing, which addresses the cause. Check cables each fall before snow. See heat cables for gutters.
