IKO Commercial Roofing Systems
Commercial Flat Roof Materials Built for Alberta Conditions
A strong commercial flat roof depends on the full system, not just the surface layer. Coastal Craft Roofing installs IKO commercial roofing materials selected around your building’s drainage, insulation needs, roof deck, and long-term performance goals.
Depending on the project, your commercial flat roofing system may include modified bitumen membranes, built-up roofing components, polyiso insulation, vapour barriers, cover boards, and waterproofing details around drains, curbs, seams, edges, and rooftop penetrations. The goal is simple: build a roof assembly that manages water properly, protects the building, and performs through Edmonton’s freeze-thaw cycles, snow load, and seasonal weather changes.
Modified Bitumen Membranes
Durable membrane options for commercial flat and low-slope roofing applications.
Polyiso Insulation
Roof insulation designed to improve thermal performance and support the full roof assembly.
Vapour Barriers & Cover Boards
System layers that help manage moisture movement, durability, and long-term membrane performance.
Waterproofing Details
Protection around drains, edges, seams, curbs, and rooftop penetrations where flat roofs commonly fail.
