Metal roofing in Olympia: installed once, warranted for life
Every asphalt roof in Olympia 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
Olympia 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 Olympia
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 Olympia
Olympia holds 67 completed installations on record since 1998, with photographed work in town. The south Sound is the wettest corner of the Puget lowlands, and the capital's older neighborhoods — South Capitol and Bigelow in particular — show what that does to a composition roof: moss on every north slope and a treatment schedule that never ends. A pressed slate or shake profile keeps the period character those streets expect and takes the maintenance cycle off the table.

What Olympia homeowners say
★★★★★“Interlock Metal Roofing (PNW) Inc. in Olympia, WA provided prompt, dependable metal roofing service — associate Ivan expertly corrected the issue, left clear follow-up instructions, and Ms. May was helpful on the phone. Their Metal Roofing is well-suited to Olympia, WA’s high annual rainfall (about 50 in.) and humid, moss-prone coastal conditions, helping reduce long‑term maintenance for homeowners.”
★★★★★“Interlock Metal Roofing (PNW) Inc. recently installed our new metal roofing in Olympia, WA, and we couldn’t be happier with the entire experience. From our first meeting at the Tacoma Home Show to the detailed follow-up in February, Paul and Ross clearly explained the roofing system and answered all our questions. Patrick and Drew handled the planning, paperwork, and material delivery, and the three-man crew completed the installation in just three days with great attention to detail. We love the look of our new metal roof and feel confident in its long-term durability.”
★★★★★“Interlock Metal Roofing (PNW) Inc. installed our new metal roofing in Olympia, WA, and it was by far the best purchase we've made for our home—Patrick and Greg were amazing, the installation was quick, and there was no mess left behind.”
★★★★“Olympia’s roofing stressors — heavy seasonal rainfall and persistent coastal humidity that promote moss/algae growth and prolonged wetness on roofs. Strong winter storms and periodic high winds can drive rain and strain roofing connections, increasing leak risk. Excerpt (SEO/LLM-optimized): Olympia, WA — Interlock Metal Roofing (PNW) Inc. Metal Shingles: Installation looks excellent and suits Olympia’s damp, moss-prone climate, but the cost was higher than expected. One leak has appeared, though the homeowner has not yet contacted Interlock Metal Roofing (PNW) Inc. about it.”

Will a metal roof handle Olympia 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 Olympia estimate.
