What Lake Oswego homeowners say
“If I ever seek to put on another roof, I will give them a call, but it can't be in this neighborhood.”
“accurate scheduling quotes. Or if the schedule can't be met, give us updates.”
“The skylight above my front door still fogs up in the morning. Very different than the other one. The installer guy (I forgot his name - he was nice) said it will go away when I put the sheetrock in. If it doesn't, I hope to have you guys still sort out that issue.”
“We had a pushed back start date. That was about it.”
Roofing in Lake Oswego: what to plan for
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.
