Metal roofing in Redmond: installed once, warranted for life
Every asphalt roof in Redmond 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 and UL 2218 Class 4 impact rating — 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 Washington homes
Redmond homeowners choose from shingle, cedar shake, slate and standing seam profiles pressed in aluminum — the character Pacific Northwest architecture expects, in Alunar®-coated colors warranted for 30 years. Aluminum cannot rust the way steel does: there is no iron in the panel, which decides the roof in Salish Sea and Strait of Juan de Fuca salt air and matters again through a long Puget Sound wet season. "Class A Fire Rated Available." Full product specifications live with the manufacturer: Interlock aluminum roofing systems.
Choosing a roofing contractor in Redmond
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 Washington under contractor licence #INTERMR75406, carried on every crew along with general liability and workers' compensation. Interlock Metal Roofing (PNW) Inc. is the authorized installer of the Interlock® Lifetime Roofing System in Washington; the licence number is verifiable with the Washington State Department of Labor & Industries.
Roofing in Redmond
Redmond holds 83 completed installations on record since 1998, and the most recent — job WAEV25002, finished in January 2026 — is documented in twelve gallery photographs: a black aluminum slate roof on an Eastside ranch home with a complex hip roof and skylights. Eastside housing stock is largely 1970s–1990s subdivisions now working through their second or third asphalt roof, and the Sammamish Valley's tree cover keeps north slopes damp well into summer.

Common questions in Redmond
Who installs metal roofing in Redmond, WA?
Interlock Metal Roofing – Washington installs lifetime interlocking aluminum roofing in Redmond, Washington — metal shingle, slate, cedar shake and standing seam profiles with concealed fasteners, a warranted 120 mph wind rating, and the Guardian lifetime limited warranty, transferable once.

Will a metal roof handle Redmond rain and moss?
Yes — aluminum gives moss nothing to root into. It 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 Puget Sound 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 Redmond estimate.
