Flat TPO Roofing - Redmond, Washington

New Roof on Historic 1906 Chelsea Apartments in Redmond

Historic Chelsea Apartments

In July 2018, Three Tree Roofing was awarded a contract to re-roof the Historic Chelsea Apartments with modern TPO. We installed a 100% waterproof, chemically resistant thermo-plastic membrane that has become the leading choice for low-pitched and flat roofs in Washington State. This roofing was a challenging and rewarding project that included limited access, multiple existing layers, carpentry repairs, and a great deal of custom stucco work. We also didn’t want to disturb the residents by traveling inside the building. We held an on-site safety meeting with our crew leader and constructed an external stair tower and garbage shoot.

This historic building, constructed in 1906, had several roofs added over the years. When we removed the old roofing and completed the carpentry repairs, we installed a .60 Mil TPO membrane. The roofing turned out great, and most residents didn’t even know we were there. Clean-up, done each day, included a magnet sweep to pick up any nails and metal debris that might have fallen during the removal process. The project time frame was 14 business days.

Our clients rely on us to provide the highest quality commercial and residential roofing solutions for their roofing projects.

History of Chelsea Apartments

In 1906, regionally famous architect Irving Harlan Thomas designed the 100-room Historic Chelsea Apartments in a fusion of English Renaissance & Italian Baroque styles. As a destination for tourists, conveniently located along the Kinnear Park trolley route, it had one of the first high-speed elevators, a modern steam-heating system, and an elaborate roof garden with a wooden pergola, palm trees, and arbors. Irving Harlan Thomas is also credited with designing the Seattle Chamber of Commerce, the Pike Place Corner Building, and various buildings at the University of Washington.
