Metal roofing in Bellingham: installed once, warranted for life
Every asphalt roof in Bellingham 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
Bellingham 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 Bellingham
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 Bellingham
Our Bellingham office is at 2219 Rimland Dr, and we hold 50 completed installations in the city since 1998, with photographed work here and in nearby Everson. Bellingham is Salish Sea country, and that settles the material question before anything else: salt air attacks steel roofing at every cut edge, scratch and fastener hole, while aluminum has no iron in it to oxidize. Our Guardian warranty carries no salt-air exclusion — a Fairhaven or Chuckanut Drive roof gets the same lifetime coverage as one inland.

What Bellingham homeowners say
★★★★“Overall a positive experience with Interlock Metal Roofing (PNW) Inc.'s Metal Shakes in Bellingham, WA — workmanship and materials look solid and we're very happy so far, but it's still early to fully recommend a lifetime‑warrantied roof after such a short time and very little rain. Bellingham's coastal, wet climate (roughly 36 in. annual precipitation) and persistent humidity encourage moss growth and prolonged moisture exposure on roofs, so a full evaluation after a typical wet season is recommended.”
★★★★★“Overall I’m happy with the look and quality of the Metal Shingles installed by Interlock Metal Roofing (PNW) Inc. in Bellingham, WA, though the contracted installation crew’s poor follow-through required a partial redo — the Interlock rep’s attic inspection and insistence on correcting the work restored my confidence. Bellingham’s wet maritime climate and coastal moisture promote moss growth and demand durable, low‑maintenance metal shingles, so the corrected installation matters for long‑term performance.”
★★★★“Interlock Metal Roofing (PNW) Inc. — Bellingham, WA Metal Shakes: Better crew–client communication (including an Interlock team member on-site as translator), more tarps, and a magnetic nail-collector would prevent asphalt dust and debris in the yard. I believe it will be a good roof.”
★★★★★“Interlock Metal Roofing (PNW) Inc. — Bellingham, WA Metal Shakes: The salesperson was great; they were fantastic.”

Common questions in Bellingham
Who installs metal roofing in Bellingham, WA?
Interlock Metal Roofing – Washington installs lifetime interlocking aluminum roofing in Bellingham, 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 Bellingham 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 Bellingham estimate.
