Metal roofing in Portland: installed once, warranted for life
Every asphalt roof in Portland is on a 15–20 year replacement clock. An Interlock aluminum system ends it: one installation, four-way interlocked panels with concealed fasteners, a warranted 120 mph wind rating installed to manufacturer specification and UL 2218 Class 4 impact rating verified via Intertek — and the Guardian lifetime limited warranty, which covers you for as long as you own the home and transfers once to the next owner.
Metal shingles & aluminum roofing profiles for Oregon homes
Portland homeowners choose from shingle, cedar shake, slate and standing seam profiles pressed in aluminum — the character Northwest architecture expects, in Alunar®-coated colors warranted for 30 years. Aluminum can't rust the way steel can, which matters in coastal salt air and through a long Northwest wet season. "Class A Fire Rated Available." Full product specifications live with the manufacturer: Interlock aluminum roofing systems.
Choosing a roofing contractor in Portland
Ask every contractor the same five questions: how panels attach (clips, single tabs, or four-sided interlock), whether fasteners are exposed, what the coating actually is, whether the warranty is manufacturer-backed and transferable, and how many metal roofs — specifically metal — the crew installed last year. Our answers are on this page and in writing at your estimate. Licensed and insured in Oregon (Oregon — CCB #130826).
Roofing in Portland
Portland is our home market — the office is at 1355 NW Everett St, and 374 completed Portland installations are on record in our job book since 1998. The photo set on this page runs from Deep Charcoal slate on the eastside to standing seam in the hills, all documented Portland addresses. On older Portland housing stock we check attic ventilation at every estimate; moss and a long wet season, not snow, are what retire most asphalt roofs here.

What Portland homeowners say
“Awesome! Professional crew from start to finish! Thank you Victor, Daniel, Anna, and Patrick! We love the results and the lifetime warranty!”
“Our new metal roof looks really nice, and our attic has been repaired and now has proper venting. The only unexpected issue is kind of cute. Baby crows like using it as a slide, but the noise is minimal. Rain sounds nice and soothing on it. Even hail isn’t too loud. To me, it’s nice to know the moment it starts raining now. Our 2 roof installers were kind and professional. We didn’t get the warning calls we needed in order to know when they would show up, so that needs improvement, whether it should come from them or the office. They finished the whole job in less time than expected even though there were additional repairs that needed to take place. We only got one section of gutter replaced and they matched it so well to our existing gutters that I don’t think anyone would be able to tell the difference. The mess outside was cleaned up very well. I think the only debris I found were small and fell out of plants weeks after they left. My plants were all unharmed too! The mess in the attic was pretty bad, so it would be worth it to add attic cleanup to your scope. Patrick, who we created the plan with was very knowledgeable and readily available to answer all of our questions. He was nice and showed no signs of annoyance with our fairly constant need for additional info. Other than the few minimal issues mentioned, it was an easy process, efficient, and we’re happy with the results.”
“We’ve had our roof for about 7 years and have been very pleased with it. Recently, I scheduled gutter cleaning which was complicated by a run of wet weather which makes the roof very slippery.”

Common questions in Portland
Who installs metal roofing in Portland, OR?

Will a metal roof handle Portland rain and moss?
Aluminum sheds moss and algae instead of feeding them the way asphalt granules and cedar do, and every panel locks to its neighbors on all four sides with no exposed fasteners for a long wet season to work through. An Interlock roof ends that cleaning cycle: no granules to hold growth, no zinc strips to maintain, and we check attic ventilation and roof drainage at every Portland estimate.
Are you licensed and insured in Oregon?
Licensed and insured in Oregon (Oregon — CCB #130826).
Why do Portland roofs grow moss on one side only?
The north slope gets least sun, so it stays damp longest through a 58-inch rain year. Moss roots between asphalt granules, holds water against the mat, and lifts each tab as it grows — which is why an asphalt roof usually fails on one aspect first. Smooth interlocked aluminum gives it nothing to root into.
Can you roof over the second layer of asphalt already on my house?
Sometimes, after inspection and where local code permits. Older Portland houses often carry two layers already, and whether the deck can take another covering is a question we answer by looking at it, not by quoting a policy.
