Gutter Installation in New Hampshire

Gutters and gutter guards in New Hampshire

New Hampshire’s Seacoast, Monadnock and Upper Valley regions all see heavy snow and ice. Strong seamless gutters with hidden hangers are the standard recommendation.

Forested lots mean plenty of leaves and pine needles, making guards a common addition. Older homes in Portsmouth and Keene often need replacement of aging gutters.

Along the Seacoast in Portsmouth and Hampton, salt air and nor’easters call for corrosion-resistant fasteners, while inland homes in Keene and Lebanon deal with deep snow.

Key facts: gutters in New Hampshire

• Typical cost: HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally; local prices vary.
• Do gutter installers need a license in New Hampshire? No statewide license exists. Ask for insurance, references and a written contract.
• Should lake-house gutters drain into the lake? It is better to send roof water to a vegetated area or swale, where it can soak in and be filtered, rather than straight into the water.
• 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.

Rain and snow

Concord averages about 42 inches of precipitation and nearly 68 inches of snow a year under the 1991–2020 normals, and the Lakes Region, White Mountains and North Country get much more snow. Nor’easters, summer thunderstorms and spring rain on melting snow all test gutters. See downspout size and placement.

Ice dams and snow

Cold winters with thaws bring ice dams to many older homes. Ice dams come from heat loss through the roof, not from gutters, but ice can pull gutters loose. Insulation, ventilation and ice and water shield at the eaves address the cause; heavier gauge and close hanger spacing keep gutters on. On metal roofs, snow guards hold snow in place. See ice dams and gutters, snow load and gutters and snow guards explained.

Old homes and mill towns

New Hampshire has many colonial homes, farmhouses and 19th-century houses in mill towns, often with wood or built-in gutters. Homes built before 1978 may have lead paint on trim and fascia, which affects how old paint is disturbed during gutter work. See gutters on historic homes and fascia repair before new gutters.

Basements and ledge

Many homes have basements, and shallow ledge and rocky soils mean water does not always soak in. Downspouts that dump at the foundation are a common cause of wet basements. Carry water away onto ground that slopes away, or to a dry well where soils allow. See downspouts and your foundation and underground downspout drainage.

The Seacoast

Portsmouth, Rye, Hampton and the Seacoast face salt air and nor’easters. Heavier-gauge aluminum or copper with stainless or compatible fasteners lasts longer near the water. See gutters near the coast.

Trees

Maples, oaks, birches and white pines surround most homes. Pine needles slip through coarse screens; fine-mesh metal guards keep them out better. Ask whether a guard sheds snow or traps it. See gutter guards for pine needles vs. leaves.

No statewide license

New Hampshire does not license general or home improvement contractors statewide, so checking the installer is up to you. Ask for proof of insurance sent directly by the insurer, local references and a written contract. New Hampshire law gives contractors a notice-and-repair process for construction defect claims, so keep the contract and correspondence. Towns may require permits for some work.

Costs and choices

HomeGuide puts seamless aluminum gutters at about $6 to $12 per linear foot installed nationally. In New Hampshire, heavier gauge and close hanger spacing for snow and ice, guards that shed snow, snow guards on metal roofs and drainage away from basements are the main choices. See our cost guide.

Choosing an installer in New Hampshire

Ask for a certificate of insurance, references from recent jobs and 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. On older homes, ask how the installer will handle painted trim that may contain lead. Avoid large up-front payments. See how to choose a gutter contractor and how to compare gutter quotes.

Lake homes and seasonal camps

Around Lake Winnipesaukee, Sunapee and the many smaller lakes, seasonal homes sit empty for much of the winter. Gutters there need to cope without regular checks: heavier gauge, close hanger spacing, guards that shed snow and extensions that carry water away from foundations and toward vegetated areas rather than straight into the lake. Plan a check before closing in the fall and after the spring thaw.

Rural wells and septic

Many New Hampshire homes have private wells and septic systems. Downspouts should not discharge onto a septic leach field or toward a shallow wellhead. Planning discharge points before installation avoids problems later. See gutters and landscaping.
