Metal Roofing in Beaverton, OR: 2026 Costs & How to Hire
Metal is having a moment in Beaverton for a practical reason: moss. Composition shingles in this climate hold moisture on the north slope, grow a mat of moss, and give up years early, while a properly detailed standing seam roof sheds water and stays clean far longer. It also costs two to three times as much, so the decision deserves real numbers. Here is what metal roofing and comp replacement cost in Beaverton in 2026, and how to verify a contractor under Oregon rules.

CCB registration is the first check, not the last
Oregon requires every construction contractor, roofers included, to be registered with the Construction Contractors Board, with a bond and liability insurance on file. Search the CCB number on the state site to confirm active status, the bond amount, insurance and complaint history before the estimate visit. Then require a certificate of insurance emailed directly by the agency naming you as certificate holder and showing workers compensation if the company has employees. Ask specifically whether the metal work is done by in-house sheet metal crews or subcontracted — standing seam is a fabrication trade, and the answer tells you who will honor the workmanship warranty in five years.
Standing seam versus exposed fastener versus comp
Standing seam hides its fasteners under concealed clips, allows for thermal movement and is the system worth buying if you plan to stay; expect 40 to 60 years. Exposed-fastener panels cost far less but rely on thousands of gasketed screws that need retorquing over time, and they look like what they are on a residential roof. Metal shingle and stone-coated steel sit in between. Compare all of it against a quality architectural composition replacement, which is the right call for many houses. Ask for panel gauge — 24 gauge is the residential standard for standing seam — the coating system, the seam type and profile, and the panel and finish warranties separately from the workmanship warranty.
Rain detailing, moss and ventilation
In this climate the details fail before the field does. Ask how valleys, sidewall and headwall flashings, chimney crickets and skylight curbs are formed and whether they are fabricated on site. Ask about a high-temperature ice-and-water underlayment under metal and a synthetic layer over the whole deck, plus how they isolate dissimilar metals so galvanic corrosion does not eat the flashings. Overhanging Douglas fir means debris and moss pressure, so plan gutter guards and a zinc strip or scheduled cleaning either way, and expect the roofer to talk about trimming branches. Ventilation still matters under metal — confirm net free vent area with real soffit intake, not just a ridge product.
Permits and what belongs in writing
Roof replacement requires a permit through the City of Beaverton Building Division, or Washington County for unincorporated addresses, and the registered contractor pulls it and schedules inspection. A fair estimate names the panel system, gauge, profile and finish, underlayment specification, flashing fabrication details, tear-off and layer count, deck replacement pricing per sheet, ventilation plan, gutter work, cleanup, and both the material and workmanship warranties in years. Payment should track progress rather than sit in a large deposit, and the last payment belongs after the inspection closes.

Common questions
How much does a metal roof cost in Beaverton?
In 2026, a standing seam metal roof runs about $24,000 to $44,000 on an 1,800 square foot roof, exposed-fastener panels $12,000 to $22,000, and a comparable architectural composition replacement $11,000 to $19,500.
Do roofers need a license in Oregon?
Yes. Roofing contractors must be registered with the Oregon Construction Contractors Board, which requires a bond and liability insurance. Check the CCB number online for active status and complaint history before you sign.
Is metal worth it over composition in this climate?
It can be if you plan to stay. Metal sheds water and resists the moss that shortens shingle life on shaded north slopes, and a standing seam roof lasts 40 to 60 years versus roughly 20 to 25 for composition here. The trade-off is two to three times the upfront cost.
What gauge and system should I ask for?
For residential standing seam, 24 gauge steel with a concealed-clip system and a quality coating is the common specification. Ask for the panel profile, coating, seam type, and the material warranty stated separately from the workmanship warranty.
