The team did a great job installing gutters on our new shop. I think the work took a little longer than they might have expected and even though it was getting dark, they stayed to finish and cleaned up the job site like pros. I will certainly use them again.

Answers To Your Questions (FAQ's)

We offer complete gutter services in Oregon, including seamless gutter and downspout installation, high-quality gutter guard installation, and reliable gutter repair for both homes and businesses.

Yes, we provide free, no-obligation quotes. Simply request a quote online or call us, and we can often provide same-day estimates.

Yes. American Gutter Service is fully licensed, bonded, and insured in the state of Oregon (CCB# 110122). This protects you from liability during the project and ensures all work meets Oregon building code requirements.

Seamless gutters are custom-formed from a single continuous piece of aluminum or copper, cut to the exact dimensions of your roofline on-site. Unlike sectional gutters made of joined pieces, seamless gutters have far fewer seams, which drastically reduces the risk of leaks and improves both durability and curb appeal. They are the preferred choice for Oregon homes due to our heavy annual rainfall.

No. When installed correctly by a professional gutter contractor, replacing or repairing your gutters will not void or affect your existing roof warranty. Our technicians are trained to work carefully around rooflines, shingles, and flashing to ensure zero damage during installation.

Seamless gutter installation in Oregon typically costs between $8 and $15 per linear foot for aluminum, and $25 to $40 per linear foot for copper. The final price depends on your home’s linear footage, number of stories, material choice, and any add-ons like gutter guards. Contact us for a free estimate tailored to your property.

Most residential seamless gutter installations are completed in a single day, typically within 4 to 8 hours depending on your home’s size and roof complexity. Larger commercial projects may require 2 to 3 days. We confirm the exact timeline during your free on-site estimate.

Yes. American Gutter Service handles both residential and commercial gutter projects throughout the Portland metropolitan area. We work with property managers, real estate firms, and business owners to install, repair, and maintain gutter systems on multi-unit buildings, warehouses, retail spaces, and office complexes.

American Gutter Service provides complete gutter solutions in Oregon, including seamless gutter installation, downspout installation, professional gutter guard installation, and reliable gutter repair for both residential homes and commercial buildings. We serve the Portland metro area and Columbia County with free, no-obligation estimates.

For most Oregon homes, 5-inch aluminum seamless gutters offer the best balance of durability, cost-effectiveness, and resistance to our heavy Pacific Northwest rainfall. Homes with large roof areas or steep pitches may benefit from 6-inch gutters for higher water volume capacity. Copper gutters are a premium option offering 50+ years of lifespan and distinctive appearance.

While we do not currently offer financing, our competitive pricing and free estimates make quality gutter installation accessible to most homeowners.

If your gutters show isolated issues like a single leak, loose bracket, or minor sagging, a targeted repair is usually the most cost-effective solution. However, if you’re seeing widespread rust, multiple cracks, gutters pulling away from the fascia board, or persistent water pooling near your foundation, a full replacement will save you money long-term.

Most residential homes in Oregon use 5-inch K-style seamless gutters, which handle standard rainfall volume effectively. Homes with large roof areas, steep pitches, or heavy tree coverage may need 6-inch gutters for increased water capacity. During your free estimate, our technicians will assess your roofline and recommend the right size for optimal drainage.

Yes. While seamless gutters cost more upfront than sectional gutters, they are significantly more durable, require less maintenance, and are far less prone to leaks. For Oregon homes that deal with constant rain from fall through spring, the reduced risk of water damage and lower long-term maintenance costs make seamless gutters a smart investment.
