The team that installed were amazing and did amazing work. They cleaned up everything in a timely manner. One feedback I would have is giving more updates on when the project was slated to be started.”

See this roof 6 photos · Deep Charcoal Shake“Interlock was great. The roof is beautiful and the crew was great to work with. Everyone we met with was kind, skilled and knowledgeable. Mike and Damon even helped us work with insurance some due to a tree falling on our house. Interlock made the overwhelming task of getting a full new roof a little less overwhelming, and we appreciate them so much for that.”

I couldn't be happier. This Aluminum roof will never need to be replaced and it makes my simple home look like a million dollar home. It's stunning. I chose black slate and it is so beautiful.”

Why Oregon roofs keep getting replaced
Months of rain, moss on the shady side and hot summer sun work on asphalt shingles every year: moss lifts the tabs, granules wash into the gutters and edges curl. Cedar shakes take on water and split. An Interlock roof has no granules to lose and nothing for moss to root into, and its panels lock to each other on all four sides.
The look of slate or cedar, without the weight
Interlock's Slate, Cedar Shingle and Shake profiles keep the look on a Craftsman bungalow, a foursquare, a Victorian or a farmhouse at roughly 0.4 to 0.7 lb per square foot, a fraction of natural slate. In a historic district, check with your local historic landmarks commission first; we bring samples and product documents to that conversation.
Built for salt air and wind
On the coast, salt air corrodes steel fasteners and coated-steel roofing; aluminum cannot rust. On the coast and in the Gorge, wind works at loose edges; Interlock panels lock on four sides with the fasteners concealed, and wind resistance is warranted to 120 mph installed to manufacturer specification.
One installer, since 1997
We plan, price and install every roof ourselves, under Oregon CCB License #130826. The manufacturer's Guardian Lifetime Limited Material Warranty comes with it, and our team works from Portland.
