Three Tree Roofing installed a 12,000 sq. ft. roof on an apartment home in Burien, Washington. We removed multiple layers of built up roofing and repaired any damaged plywood, framing and fascia. We then installed new WeatherBond Gray .60 Mil TPO roofing, added venting and custom edge flashings. The Ambaum Apartments' timeline was 2-3 weeks.
