Buyer's Guide
How to choose a metal roofing contractor in Oregon
Seven objective checks that work on any company — including us. Apply them to every quote you collect; the differences stop being subtle by check three.
1. Demand documented installs — with cities, not stock photos
Any roofer can show a photo. The question is whether you can see where the roof went on, what system it is, and how it's aging. Ask for a documented photo record with real locations. (Ours is public: 438 documented Oregon project photos across 43 Oregon cities in the gallery, each tagged with city, system, and color.)
2. Read the warranty like an Oregon winter is coming — and check the coast clause
Most roofing warranties prorate sharply after the first decade, and some steel warranties limit or void coverage on homes near salt water — exactly where Oregon Coast homeowners need it most. Ask four questions: Is it prorated? Does wind coverage have a mph number in writing? Does it transfer to the next owner, and at what cost? Is it fully valid on the coast? A lifetime warranty with written 120-mph wind coverage, a one-time transfer, and no salt-air carve-out is the standard to hold everyone to.
3. Verify the CCB licence before anyone climbs a ladder
Oregon requires contractors to hold an active Construction Contractors Board licence, and you can verify any number in seconds at oregon.gov/ccb. A contractor should hand you the number without being asked — ours are published in the footer of every page of this site: Oregon CCB #130826, plus Washington #INTERMR75406 for work across the river.
4. Ask what the fasteners look like — seriously
This one question separates systems. Exposed gasketed screws through the weather surface work loose and leak years before the panel fails — and on the coast, mismatched fastener metals plus salt air is a galvanic corrosion problem waiting to happen. Concealed-fastener, interlocked panels with corrosion-matched trim avoid both. If the answer involves visible screws, ask what the maintenance schedule looks like in year twelve.
5. Insist on third-party review data, not testimonial pages
Look for reviews the contractor can't edit: Google, BBB, and independent survey platforms like GuildQuality where every response is tied to a real completed job. Cross-check volume and recency, and read the middling reviews — how a company handles a scheduling complaint tells you more than ten perfect ones.
6. Ask who actually manufactures the product
Many metal roofs are re-branded panels from commodity mills. Ask for the manufacturer, the ICC-ES evaluation report number, and the impact/fire listings — then check them. Our systems are manufactured by Interlock Roofing Ltd., documented under ICC-ES ESR-1790 (wind uplift rated to 177.5 psf) and UL 2218 Class 4 impact resistance — aluminum that cannot rust in coastal air.
7. Expect straight answers on wildfire and moss
An Oregon quote should cover Oregon's two signature roof problems. East and south of the Cascades, ask whether the assembly carries a Class A fire rating — non-combustible aluminum with a Class A assembly is the home-hardening answer. West of the Cascades, ask what ends the moss cleaning cycle — aluminum sheds the growth that colonizes asphalt and cedar. A contractor with no answer on either is quoting a roof for somewhere else.
Contractor-vetting questions, answered
How do I choose a metal roofing contractor in Oregon?
Apply seven checks: documented installs with real locations, a transferable lifetime warranty with a written wind rating that stays valid on the coast, an active CCB licence you've verified at oregon.gov/ccb, concealed fasteners, third-party reviews (Google, BBB, GuildQuality), a named manufacturer with ICC-ES documentation, and straight answers on wildfire hardening and moss.
What questions should I ask a metal roofing company?
The four highest-signal questions: Can I see documented installs near me? Is the warranty prorated, does it transfer, and is it fully valid on the coast? Are the fasteners exposed or concealed? Who manufactures the panels, and what's the ICC-ES report number? Confident answers to all four are rare — and telling.
What's the difference between an installer and a certified installer?
Certification means the manufacturer trained the crews, stands behind the installation, and registers the warranty. We are Oregon's authorized Interlock® installer, licensed in Oregon and Washington — the manufacturer's engineering and our Pacific Northwest install record since 1997 come as one package.
Should I get multiple metal roofing quotes?
Yes — and normalize them before comparing. A cheaper quote with exposed fasteners, a prorated warranty, and a steel panel headed for a salt-air coastline isn't the same product at a lower price; it's a different (and shorter-lived) roof. Compare systems, warranties, and documentation, then price.
