Commercial Roof Systems
System choices are shaped by the existing assembly, drainage, insulation, attachment, code needs, rooftop traffic, and ownership goals.

TPO 60 MilSixty-mil TPO is the dependable everyday single-ply for Seattle low-slope roofs, welding into watertight seams and reflecting heat at a thickness that balances durability and cost for most commercial buildings.
TPO 80 MilEighty-mil TPO adds thickness for high-traffic or harsh-exposure roofs, giving Seattle buildings extra puncture resistance and a longer service life where rooftop activity or equipment puts heavier demands on the membrane.
KEE Roof SystemsKEE membranes deliver PVC-grade chemical and weld strength while staying flexible in our cool, damp air, a durable single-ply for Seattle restaurants and plants exposed to grease or aggressive rooftop emissions.
EPDM WhiteReflective white EPDM keeps rubber's flexibility while cutting rooftop heat, a useful option for Seattle buildings that want cool-roof benefits during our limited summer sun without sacrificing the membrane's freeze-thaw resilience.
Fleeceback TPOFleeceback TPO bonds a fabric backing to the membrane for added puncture resistance and adhesion, a robust single-ply for Seattle roofs with foot traffic or irregular substrates that benefit from a fully adhered system.
Built Up AsphaltBuilt-up asphalt layers multiple plies into a heavy, redundant membrane, and on older downtown Seattle roofs we evaluate whether the existing gravel-surfaced system can be repaired, recoated, or is ready for replacement.
Modified Bitumen SBSSBS modified bitumen adds rubber polymers for cold-weather flexibility, so it stays workable and crack-resistant in Seattle's cool climate, making it well suited to roofs that see temperature swings and foot traffic.
PVC Roof SystemsPVC's hot-air-welded seams form a monolithic, chemical-resistant membrane that handles grease and ponding, a reliable single-ply for Seattle restaurants and industrial roofs where our frequent rain lingers on flat decks.
EPDM BlackBlack EPDM is a proven rubber single-ply that handles freeze-thaw and resists weathering, making it a sound, economical choice for Eastside and higher-elevation Seattle-area roofs where reflectivity matters less than durability.
Modified Bitumen APPAPP modified bitumen uses a plastic-modified asphalt that torches down into a tough, UV-tolerant surface, a dependable multi-ply option for Seattle roofs needing redundancy and proven performance through long, wet winters.
Spray Polyurethane FoamSpray polyurethane foam delivers a seamless, insulating membrane in one application, ideal for irregular Seattle roofs, though it must be installed during a dry, low-humidity window our damp climate rarely offers.
Silicone Roof CoatingSilicone coatings excel where water ponds because they resist standing moisture far better than most products, restoring and extending sound Seattle membranes while sealing seams against the region's persistent rain.
