How Your Metal Roof Install Works
Three steps. No surprises.
Free Roof Assessment
We measure the roof, check the decking, and talk through panel profiles and colors. Most assessments take under an hour.
Written Estimate
Line-item pricing with the exact panel system, gauge, underlayment, and trim called out. Warranty terms in writing.
Professional Installation
Most residential metal roofs go on in two to four days. Panels cut to length on site, flashed and sealed for wind-driven rain.
Metal Systems We Install
Standing Seam
Concealed-fastener panels, the premium system for Northwest rain. No exposed screws to loosen and leak over time.
Exposed Fastener Panels
Cost-effective ribbed panels for homes, shops, and outbuildings. Properly gasketed and torqued to spec.
Re-Roof to Metal
Tear-off of the old asphalt and a clean transition to metal, including underlayment rated for metal systems.
Flashing & Trim
Ridge caps, valleys, sidewall and chimney trim custom-bent. Metal roofs live or die at the details, so that is where we spend the time.
Snow & Rain Management
Snow guards, high-capacity gutters, and drainage planning for roofs that shed water fast.
Metal Roof Repairs
Fastener replacement, sealant renewal, panel swaps, and leak repair on existing metal roofs.

Frequently Asked Questions
How much does a metal roof cost compared to asphalt shingles?
Roughly two to three times the upfront cost of architectural shingles, with two to three times the lifespan and far less maintenance. Over the life of the home the totals get close, and metal usually wins if you plan to stay put.
How long does a metal roof last in Western Washington?
40 to 70 years for a properly installed system. Moss also has a much harder time getting established on metal, which matters here more than almost anywhere.
Is a metal roof noisy in the rain?
Not on a residential install. Over solid decking and underlayment, a metal roof is about as loud as asphalt shingles. The loud-rain reputation comes from open-frame barns and patio covers.
Can you install metal over my existing shingles?
We recommend a full tear-off. It lets us inspect and repair the decking and keeps the manufacturer warranty clean. Installing over old shingles hides problems that get expensive later.
Do you charge for the inspection or estimate?
No. Both are free. You get a photo report and a written estimate whether you hire us or not.
Do you warranty metal roof installations?
Yes. Written workmanship warranty on the installation, plus the manufacturer's panel and finish warranties, commonly 40 years on the paint system.
