Oregon asks more of a roof than almost anywhere in America — and asks differently depending on where you live. West of the Cascades, forty-plus inches of winter rain feed the moss that shortens the life of asphalt and cedar. On the coast, salt air corrodes steel at every cut edge. In the Columbia Gorge, sustained wind works loose anything that isn't mechanically locked down. Interlock's four-way interlocking aluminum answers all four climates with one system — no rust, nothing for moss to root into, wind uplift documented to 177.5 psf — and we've been installing it for Oregon homeowners from our Portland office since 1997.

I love my Interlock roof! No more climbing up to clean it, and no more gritty debris falling into my garden after a few years. It looks fantastic and performs exactly as it should. The installers were excellent—knowledgeable, detail-oriented, and personable. Ivan is a gem! He handled a small flashing addition efficiently and cleaned the entire roof with a blower in no time. After almost ten years, it's still the only roof I would choose.

We’ve had our roof for about 7 years and have been very pleased with it. Recently, I scheduled gutter cleaning which was complicated by a run of wet weather which makes the roof very slippery.
