Seattle, renowned for its diverse architecture and distinct weather patterns, poses unique challenges and opportunities for flat roofing systems. In this insightful blog post, we delve into essential considerations for homeowners in the Seattle area, ensuring informed decisions for lasting roof integrity.


Understanding Flat Roofs

Seattle’s climate, marked by wet winters and dry summers, demands roofing solutions capable of enduring persistent moisture and occasional heavy rainfall. Flat roofs, with their minimal slope, require meticulous installation and maintenance to prevent water pooling and leaks. Installing PolyISO over living space without ceiling insulation is crucial to regulate interior temperatures and enhance energy efficiency.
