Seamless Gutter Installation—Blue Moon Keeps Portland Homes Dry

Custom‑cut on site, leak‑proof for decades, and color‑matched to your trim in a single afternoon.

Why Upgrade Your Gutters?

A properly installed roof does more than keep water out. It:

Protect the Foundation

Direct rainwater away from basements and crawl spaces, avoiding costly structural repairs.

Stop Rot & Mold

Dry fascia and siding last longer and keep indoor air healthier.

Prevent Landscape Washout

Controlled drainage saves mulch, plants, and hard‑scape.

Boost Curb Appeal

Fresh, straight runs and baked‑on finishes sharpen roof lines and resale value.

Gutter Guard & Leaf Protection Upgrades

Keep fir needles and maple leaves out with micro‑mesh guards rated for 200″/hr of rainfall. Guards can be added during install at a reduced labor cost.

Financing & Seasonal Promotions

Zero‑interest for 6 months on projects over $1,000 (OAC). Book installs between November–February for off‑season discounts up to 10 %.

Our Five‑Step Installation Process

On‑Site Measurement & Flow Audit

Laser level determines pitch; we size downspouts for Oregon rainfall maps.

Custom Roll‑Forming

Seamless troughs extruded from a single aluminum coil at your curb—no joints between corners.

Secure Hidden Hangers

Screw‑anchored every 24″ into rafter tails for maximum pull‑out resistance.

Downspout & Drainage Setup

Fasten downspouts with two straps per story; option to tie into French drains or rain barrels.

Cleanup & Water Test

Hose test confirms proper slope; we haul away old gutters and metal scraps.

Typical home: 3–6 hours start to finish.

FAQ

Is 5″ or 6″ better for my roof?

Steep or large roofs benefit from 6″ troughs with 3×4″ downspouts; most standard pitches work with 5″ gutters.

Will new gutters damage my shingles?

No. Hidden hangers attach to fascia, not the roof deck—shingle warranties remain intact.

How much do seamless gutters cost?

Aluminum 5″ systems run $9–$12 per linear foot installed; copper is $25 + per foot. A 200‑ft home averages $1,800–$2,400 in aluminum.

Do you remove old gutters?

Yes, tear‑off and disposal are included. We recycle aluminum and steel whenever possible.

Can I add guards later?

Absolutely, though adding them during initial installation saves labor and ensures perfect fit.
