Products Available for Seattle 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 integrated heat trace cable to melt ice and snow. Built from the same military-grade 6063 aluminum with a 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 Seattle Gutters Clog: Market, Weather and Trees

Seattle is the tech-and-trade capital of the Pacific Northwest: seven Fortune 500 companies are headquartered in the city — Amazon, Starbucks, Expeditors International, Nordstrom, Weyerhaeuser, Expedia Group and Zillow — with Costco, Microsoft and Paccar in the surrounding Puget Sound cities. Trade is the other pillar, with the Port of Seattle the eighth-largest U.S. port by container capacity. About 51% of King County's owner-occupied homes were built before 1980.

Seattle averages 39.34 inches of precipitation a year and about 25.2 nights at or below freezing, with 6.3 inches of snow and a heating load of 4,376 degree days. The Pacific Northwest failure mode is wet, matted conifer litter and overflowing gutters, not ice.

The canopy supplies the rest. Western Washington's old forests are dominated by western hemlock, one of the most shade-tolerant species in the region, growing with its much larger associates Douglas-fir, Sitka spruce and western redcedar, with red alder abundant at lower elevations and bigleaf maple through the lowlands. Conifers shed year-round with the heaviest cast in autumn and after windstorms; maple and alder flush in autumn.

What Gutter Guards Cost in Seattle, WA

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 Seattle, 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. Seattle's long October-through-May wet season and conifer canopy of Douglas fir, western red cedar, and hemlock shed needles and cones that mat down, while bigleaf maple and alder drive a heavy fall leaf load. 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.

Because homes differ, the honest number is your own roofline — measured, not estimated. Every GutterDome quote is free and based on an in-home assessment of your actual gutter run.

High Fire Hazard Areas in Seattle, WA

Seattle’s own hazard plan says a city wildfire is unlikely — it has no large wildlands close in — and the real exposure sits in the forested watersheds, which Seattle Public Utilities and City Light protect with their own wildland crews.

States across the West are adopting wildland-urban interface codes that require roof gutters to be noncombustible and to have a means of keeping leaves and debris from collecting in them. GutterDome's 6063 extruded aluminum frame and T304 stainless-steel micro-mesh are noncombustible, and they keep the debris out. Read about gutter guards for high fire zones →

Rainwater Harvesting in Seattle, Washington

RainWise — run by King County and Seattle Public Utilities — covers up to 100 percent of the cost of cisterns and rain gardens in eligible basins, with an average rebate near $4,740. Larger buildings are explicitly encouraged: the bigger the roof, the bigger the rebate.

GutterDome products offer superior first stage filtration for rainwater harvesting systems, making your secondary filters last longer and perform more efficiently. A 1,000-square-foot roof sheds roughly 600 gallons from a single inch of rain, so the cleaner that first pass runs, the more of it you can actually use.
