Roofing in Mercer Island: what to plan for

Why Puget Sound roofs keep getting replaced

A long wet season, shade from the firs and 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, a Tudor, a Victorian or a mid-century home 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 winter wind

On Puget Sound, Hood Canal, the islands and the Strait, salt air corrodes steel fasteners and coated-steel roofing; aluminum cannot rust. Winter storms hit shoreline roofs hardest; Interlock panels lock on four sides with the fasteners concealed, and wind resistance is warranted to 120 mph installed to manufacturer specification.

We plan, price and install every roof ourselves, under Washington State Contractor Registration #INTERMR75406.
