Metal roofing in Sequim: installed once, warranted for life
Every asphalt roof in Sequim 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
Sequim 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 Sequim
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 Sequim
Sequim is an unusual case: it sits in the Olympic rain shadow, the driest place west of the Cascades, and directly on the Strait of Juan de Fuca. So the moss argument that dominates Puget Sound matters less here, and the salt-air argument matters more — open-water exposure with none of the rainfall that would rinse it off. Our documented Sequim work is a 2019 installation photographed across six gallery images. Aluminum cannot rust; that is the whole case on this coastline.

What Sequim homeowners say
★★★★“Interlock Metal Roofing (PNW) Inc — Sequim, WA: On a Metal Shingles install I immediately caught crew miscommunication that omitted ventilation sheathing on a vaulted ceiling and then misapplied it elsewhere, averting moisture and ventilation failures; correct ventilation is especially important in Sequim’s rain‑shadow climate (≈16 in/yr) while coastal humidity/fog can still drive condensation under roofs, so precise specs and crew understanding are critical for long‑term metal shingle performance.”
★★★★★“Seemingly pleased with the product and the crew—Interlock Metal Roofing (PNW) Inc. installed Metal Shingles in Sequim, WA; the crew did great work and kept to the schedule, but splitting resources with another project (some days a full crew, other days only a couple of guys) limited their ability to focus on one job at a time, affecting pacing and continuity. In Sequim’s relatively dry rain‑shadow climate yet exposed to coastal moisture and occasional wind—conditions that make proper fastening and corrosion resistance important for metal shingles—this solid workmanship still delivered a satisfactory result.”
★★★★★“Thorough, itemized estimate with triple‑checked measurements to prevent last‑minute costs from inaccurate field dimensions — Interlock Metal Roofing (PNW) Inc. recommends precise measuring and premium Metal Shingles for Sequim, WA, where the Olympic rain‑shadow yields low annual rainfall (~16 in.) yet marine coastal moisture and salt‑air exposure can accelerate corrosion and require careful material/installation planning to avoid costly rework.”
★★★★★“Sequim, WA Metal Shingles — Interlock Metal Roofing (PNW) Inc.: Sequim sits in the Olympic rain shadow with only about 16 inches of annual precipitation, yet it still gets concentrated fall/winter storms and coastal moisture that can carry salt and raise corrosion risk for roofs. Specify corrosion-resistant coatings, stainless or sealed fasteners, and roof details that shed debris and limit shaded, moss-prone spots; Metal Shingles from Interlock Metal Roofing (PNW) Inc. installed to those standards perform best in Sequim, WA.”

Will a metal roof handle Sequim 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 Sequim estimate.
