King, WA
King County is our home market — the Seattle office is at 5608 17th Ave NW, and 394 completed installations are on record in Seattle alone since 1998, with another 83 in Redmond, 51 in Bellevue and 24 in Kirkland. The county spans two very different roofing problems. West of I-5, the story is the wet season: Craftsman bungalows in Ballard and Wallingford, mid-century homes in Bellevue and Kirkland, all growing moss on the north slope every winter because asphalt granules and cedar fibers hold water for eight months. East and south, the foothills take over — North Bend, Snoqualmie, Enumclaw and Black Diamond carry real wet snow. Interlocked aluminum handles both: nothing for moss to root into, and panels that shed snow with no exposed fasteners for freeze–thaw to work loose.

We needed a small repair on our roof and Ivan came quickly. The repair was done quickly. Ivan explained everything he’d done and answered other questions professionally. Great customer service; we would highly recommend this company. We love our roof!

— Leon G., Oak Harbor, WA
We are very happy with our new roof. The crew that replaced the roof were hardworking and efficient, and the finished product looks great!

Local roofing factors: Ilwaco’s coastal marine climate brings high rainfall and persistent moisture that promote moss/algae growth, while coastal winds and salt spray can accelerate corrosion and material wear. Interlock Metal Roofing (PNW) Inc. — Ilwaco, WA: Outstanding Metal Shingles with a top-notch install crew and excellent product quality; communication between Angela and Igor could be improved, but overall a highly recommended choice for Ilwaco’s wet, moss-prone coastal conditions.

I have a cream and dark brown Tudor 2 story home and bought the slate profile in Tudor Brown. Many Tudor homes in my neighborhood also had tile concrete roofs that are 46 years old and near end of life. All have replaced with shingles, just doesn't look right and I think cheapens the look of the home. I payed way more than I planned but it was worth it. The roof is stunning! The crew here in Vancouver WA led by Tony with Caliss, Rueben and one other young man were the hardest working, most particular skilled craftsmen I could have hoped for. Very Happy!
