About

Clow Roofing & Siding Co is a commercial roofing and exterior contractor serving the Portland, OR metro area, delivering roofing solutions across the full range of flat and low-slope systems that Pacific Northwest facility managers rely on. Operating in one of the most weather-demanding markets in the country, Portland-area commercial properties face persistent moisture load, freeze-thaw cycling, and moss accumulation — challenges that demand roofing contractors with deep familiarity with membrane performance and waterproofing best practices. Clow Roofing & Siding Co addresses these needs with expertise spanning EPDM, TPO, modified bitumen, built-up roofing, metal roofing, and protective coatings — the systems most commonly specified for office buildings, retail centers, industrial facilities, warehouses, multifamily properties, and mixed-use developments throughout the region. For facility managers and property managers overseeing commercial assets in Portland, a contractor that understands both roofing membranes and exterior cladding systems offers meaningful operational value: a single point of accountability for building envelope performance, streamlined vendor management, and consistent workmanship across roof and wall assemblies. Portland's commercial real estate stock — from aging warehouse conversions in the Central Eastside to newer mixed-use developments along the waterfront — presents a wide variety of existing roof conditions, and a contractor experienced across multiple system types is better positioned to assess, repair, or replace whatever system is already in place. Facility managers evaluating Clow Roofing & Siding Co for their Portland-area properties are encouraged to request a detailed scope of services, system-specific references, and current licensing and insurance documentation to confirm fit for their portfolio requirements.
