Commercial Roofing
Westerly Ventures provides comprehensive commercial roofing services for offices, retail centers, warehouses, restaurants, and industrial facilities across Western Washington. We specialize in flat and low-slope roofing systems designed to handle the heavy rainfall and weather extremes of the Pacific Northwest.
Our commercial roofing solutions include TPO (thermoplastic polyolefin), EPDM (ethylene propylene diene monomer), modified bitumen, and built-up roofing systems. We help property managers and building owners select the right system based on building use, budget, energy efficiency goals, and expected lifespan.
We also offer commercial roof coatings and restoration services that can extend the life of an existing roof by 10-15 years at a fraction of replacement cost. Our preventive maintenance programs include scheduled inspections, drain clearing, seam checks, and minor repairs to prevent costly emergencies.
