Composite Asphalt Shingles / Flat TPO Roofing - Seattle, Washington

New Composite Shingle/Flat TPO Roof for Seattle Church

Composition Low-slope Shingles and TPO Commercial Roof

This commercial roofing project required a combination of composition low-slope shingles with a TPO membrane roof system. This is the best choice for this roof because it will stand up to winds better than other types of roofs. The old roof was leaking and caused wood damage to the walls. Our carpenters repaired all of the damaged wood during the tear off. Having journeyman carpenters on staff is a huge benefit because it keeps our jobs on schedule, saves you money in labor costs, and guarantees that everything gets done right the first time.

As a Certified CertainTeed Roof Installer and Certified Weatherbond Roof Installer, Three Tree Roofing is proud to have the opportunity to install both the CertainTeed Integrity Roof System and the Weatherbond Membrane Roof System on this beautiful Seattle church. The combination of CertainTeed composition low-slope shingles and a Weatherbond TPO membrane roof system is a handsome, long-lasting and energy-efficient roof.

Our clients rely on us to provide the highest quality commercial and residential roofing solutions for their roofing projects. If you have any questions about commercial buildings or residential buildings, feel free to contact us for your new roof or give us a call at 206-312-7663 (ROOF)!
