Seamless Gutters—Custom‑Formed by Blue Moon for Leak‑Free Portland Homes

One continuous run, zero joints to fail, installed in hours and warranted for years.

Why Seamless Beats Sectional

No Leaky Joints

Fewer seams mean fewer drip points and far less maintenance.

Exact Fit & Pitch

Each trough is roll‑formed on site to match your fascia—no bulky overlaps.

Stronger, Straighter Lines

Hidden hanger screws every two feet resist Pacific Northwest wind and snow loads.

Cleaner Curb Appeal

Baked‑on enamel (or raw copper) keeps color uniform and edges crisp.

Color Palette & Finishes

Choose from 30+ Kynar® enamel hues—Matte Black to Pacific Slate—or go timeless with raw copper that patinas to verdigris. We bring full‑size color chips so you can see tones against your siding before deciding.

Cost & Financing

Seamless aluminum systems run $9–$12 per linear foot installed; copper starts around $25/ft. Zero‑interest financing for six months on projects over $1,000 (OAC).

Seamless troughs extruded from a single coil, cut to length, and notched precisely at corners.

Hidden Hanger Installation

Screw‑anchored into rafter tails every 24″; downspouts strapped twice per story.

FAQ

How long do seamless gutters last?

Aluminum averages 20–25 years; copper can exceed 50 years with minimal upkeep.

Will new gutters match my existing downspouts?

Yes. We color‑match or replace downspouts for a uniform look and performance.

Do you install gutter guards at the same time?

Absolutely, and adding them during installation saves on labor.

Will installation damage my roof or siding?

No. Hangers anchor to fascia boards, not roof decking; siding is protected with ladder standoffs.

Can you run seamless gutters around a bay window?

Yes—our machine bends to the exact angle for continuous flow with no splice.
