Products Available for New Hampshire Homes

GutterDome (GD45 & GD67)

Available in two sizes to fit virtually any gutter system. GD45 is a 40-mesh gutter guard (fits 4" – 5" gutters, actual width 6-1/8") designed for standard-width gutters in residential applications. GD67 is a 40-mesh gutter guard (fits 6" – 7" gutters, actual width 7-1/2") built for larger gutters in both commercial and residential applications. Both are constructed from the highest quality military-grade 6063 extruded aluminum, tempered to T5 strength, with surgical-grade stainless-steel wire mesh and a corrosion-proof anodized finish. Backed by our 30-Year Lifetime Limited Warranty.

GutterDome Magma (GD45M, GD67M & GD45AM)

Magma is our enhanced mesh gutter guard for high-flow, high-performance gutter protection. The GD45M is a 20-mesh gutter guard (fits 4" – 5" gutters, actual width 6-1/8") engineered for inside miters, simulated miters, and high-water-flow areas. The GD67M extends Magma's superior water-shedding design to larger gutters (fits 6" – 7" gutters, actual width 7-1/2") for both commercial and residential applications. The GD45AM is the same plain-weave #20 Magma mesh carried on the Adjustable profile, which installs above a 6/12 pitch where a guard cannot be tucked under the roofing material. Plain weave 20-mesh stainless-steel is the recommended choice for cold-weather and snow regions — especially above doorways or when paired with an aftermarket integrated heat-trace cable to melt ice and snow. Built from the same military-grade 6063 aluminum with an automatically transferable 30-Year Lifetime Limited Warranty.

GutterDome Adjustable (GD45A)

This innovative 40-mesh gutter guard fits 4" – 5" gutters with an actual width of 5-1/8". It installs where you can't tuck under roofing material — ideal for steeper roof pitches above a 6/12 pitch — and works in combination with our private labeled Clynch Channel fastening system. Compatible with shingle, metal, tile, and cedar shake roofs. Military-grade 6063 extruded aluminum with a clear anodized finish.

GutterDome uPVC (GD45P)

Our multi-patented dome design in an innovative white uPVC frame. A T304 stainless-steel plain-weave #30 mesh (900 holes per square inch, 595 microns) keeps out leaves and debris, while the corrosion-proof, UV-resistant uPVC withstands weathering year-round. Thermally efficient, self-extinguishing, lightweight, and low maintenance — sealed with a 20-year grey silicone sealant and covered by a 20-Year Lifetime Limited Warranty. Fits standard 4" – 5" gutters.

Why New Hampshire Gutters Clog: Market, Weather and Trees

New Hampshire is northern New England's manufacturing state — the Granite State, with roughly 1,700 manufacturers employing over 67,000 people, and no sales tax and no broad-base income tax. It is small enough to be the tenth-least populous state and distinctive enough to hold the first primary in the presidential cycle. About 49.1% of Hillsborough County's owner-occupied homes were built before 1980 (47.8% statewide) — the youngest housing stock in its group, on a $421,100 median home value.

New Hampshire averages 41.95 inches of precipitation a year and about 165 nights at or below freezing, with 67.7 inches of snow and a heating load of 6,980 degree days. That is the highest freeze-day count and the heaviest heating load in its group on only 42 inches of precipitation — a deep-winter market where ice, freeze-thaw and snow load come before leaf volume. Figures are Concord normals.

The canopy supplies the rest. The hemlock–hardwood–pine forest is the most widespread habitat in the state, covering almost half of New Hampshire south of the White Mountains, and eastern white pine leads growing-stock volume, followed by red maple, northern red oak and eastern hemlock. The 2023 pest report mapped spongy moth defoliation on 72,000 acres of red and white oak. White pine needles and cones lead, with red maple, red oak and beech leaves in autumn, plus frass and litter in outbreak years.

"I love GutterDome because absolutely no leaves get in! Other gutter guards' mesh was too fine not allowing water flow through and they paled in comparison."

What Gutter Cleaning Costs in New Hampshire

Professional gutter cleaning runs $225 to $500 per visit nationally, based on published 2026 industry cost surveys, and most homes need it twice a year - roughly $450 to $1,000 every year, for as long as you own the home. Rates vary by market, roof height, roofline access and how much debris has built up, so confirm the local number with a cleaning company in New Hampshire. The figure worth comparing is that recurring annual total against a one-time installation - see where GutterDome installs.

What Gutter Guards Cost in New Hampshire

GutterDome's ultra-premium gutter guards are installed at a national average of $22 to $32 per linear foot. The average American home carries ~150' of rain gutter. The range is wide on purpose — roofline size and shape, access, and the profile you choose all move the final installed price, so the honest number is your own roofline, measured.

What changes from market to market is not the product — it is local installer competition and market demographics. In New Hampshire, installed pricing typically runs 10% to 20% above or below the national average, and the three factors below are what move it.

Roofline size and shape. A single-story ranch with long straight runs prices differently than a cut-up two-story with dormers and multiple pitches — more linear feet, more cuts, more labor.
Gutter size and height. Older homes with 5-inch gutters and steep pitches take longer to fit than newer builds with 6-inch gutters at walkable heights. Two-story access adds labor time on every run.
Debris load. New Hampshire is one of the most forested states in the country — heavy maple, oak, birch, and beech leaf drop plus white and red pine and hemlock needles year-round — over winters that run about 44 inches of snow on the Seacoast and far more in the White Mountains. Homes under that kind of load benefit most from the ultra-premium micro-mesh profiles, which is a model choice as much as a price one.

If your gutters are sagging, pulling away from the fascia or leaking at the seams, they need gutter repair or gutter replacement before any guard goes on. Most of that work is fixable in place — loose hangers, open seams, a run that has lost its pitch — and replacement is the answer only when the metal itself has failed along its length. Not every Authorized Dealer offers the same services, so check with your local Authorized Dealer about gutter repair and replacement before the guard work is scheduled.

Because homes differ in size, design and construction, the honest number is your own roofline — measured accurately, not estimated. Each and every GutterDome quote is free and based on an in-home assessment of your actual rain gutter system and specific requirements.
