Seamless aluminum gutter installation in the Greater Seattle area runs $9 to $16 per linear foot installed — about $1,350 to $2,100 for a typical single-story home and $2,000 to $3,600 for a two-story. Seamless aluminum is the standard choice on Pacific Northwest homes because it has no mid-run joints to leak and lasts 25 to 30 years.

Aluminum Gutter Installation FAQ
How much does aluminum gutter installation cost in the Greater Seattle area?
Seamless aluminum gutters run $9 to $14 per linear foot installed for 5-inch and $11 to $16 per linear foot for 6-inch. A typical single-story home (about 150 linear feet) lands at $1,350 to $2,100, and a two-story home (220 to 260 feet) runs $2,000 to $3,600.
Why choose seamless aluminum over sectional gutters?
Seamless aluminum is cut to length on-site, so there are no mid-run joints to leak. That matters in the Pacific Northwest, where sectional joints become a 5-to-7-year repair clock under 36+ inches of annual rain. Seamless aluminum lasts 25 to 30 years; sectional runs 12 to 18.
Should I get 5-inch or 6-inch gutters for the Pacific Northwest?
For homes under heavy tree canopy or with steep roof pitches, 6-inch K-style is worth the small upcharge — it moves 40 percent more water and clogs less. On simpler roofs with light tree exposure, 5-inch is fine.
How long does aluminum gutter installation take?
Most single-story homes are completed in one day. Larger two-story homes with complex rooflines or extensive downspout runs may take a second day.
Do aluminum gutters come with a warranty?
Yes. The Roofing Titan backs seamless aluminum installations with a workmanship warranty on top of the manufacturer's finish warranty on the aluminum coil stock.

Seamless Aluminum Gutter Installation FAQ
Why choose seamless aluminum gutters over sectional ones?
Seamless aluminum gutters are fabricated in one continuous piece on-site. Unlike sectional gutters sold at hardware stores, they have no joints or seams along the length of your home. This eliminates the weak points where leaks, rust, and debris clogs usually start.
Do I need 5-inch or 6-inch gutters for my home?
For most homes in the King County area, we recommend 6-inch oversized gutters. Washington's heavy rainfall requires the extra capacity to handle large volumes of water quickly, preventing overflow that can damage your siding and foundation.
Will my new aluminum gutters rust or peel?
No. Aluminum is naturally rust-resistant. Additionally, our seamless gutters come with a baked-on enamel finish available in multiple colors. This industrial coating is designed to resist chipping, peeling, and fading for decades.
How do you attach the gutters to the house?
We use heavy-duty hidden hangers screwed directly into the fascia board every 24 inches. This is far stronger than the old "spike and ferrule" method (nails), ensuring your gutters won't pull away from the house during heavy snow or ice loads.
How long does the Seamless Aluminum Gutter installation process take?
Because we manufacture the gutters right in your driveway using our mobile machine, most residential seamless aluminum gutter installations are completed in just one day. We remove your old gutters and haul them away as part of the service.
TRANSPARENCY. TRUST. TITAN.
