Custom Commercial & Industrial Roofing Solutions

Every commercial facility has unique demands—and your roof should be built to match. Pacific West Roofing delivers custom commercial and industrial roofing solutions backed by over 45 years of experience. Whether you’re replacing a flat roof in Lake Oswego, upgrading ventilation in a warehouse in Tigard, need metal roof systems for a warehouse in Tigard, or require ongoing roof maintenance for a retail property in Beaverton, we manage your project from start to finish.

From assessment and planning to certified installation, we handle the entire process to protect your building and maximize long-term value

Commercial / Industrial Roofing & Ventilation Systems

We start every commercial roofing project with a deep understanding of your building’s structure, HVAC systems, and internal operations. This ensures the right fit between your roof, its insulation and membrane, and the performance of your ventilation system.

We coordinate directly with facility managers and HVAC contractors for seamless execution. Our ventilation installations are ideal for manufacturing centers, warehouses, retail properties, churches, schools, and other high-occupancy buildings.

Commercial / Industrial Roof Replacement

If your commercial building’s roof is past its prime—or if the original roof system no longer supports your current operations—it’s time for an upgrade.

Our certified installers work around your schedule to complete full commercial roof replacements with minimal disruption. We help businesses in Beaverton, West Linn, and Oregon City modernize their roofs for improved insulation, moisture protection, and fire safety.

Commercial / Industrial Roof Inspection, Maintenance & Repair

Our team provides ongoing maintenance, scheduled inspections, and emergency commercial roof repair across the Portland Metro area. These services extend roof life, reduce liability, and lower your long-term cost of ownership.

Without annual inspections, even small issues—like ponding or membrane punctures—can lead to major water intrusion or insulation failure. We help building owners avoid downtime and code violations.

Types of Commercial & Industrial Roofing

We specialize in roofing systems that outperform in the Pacific Northwest climate:

3-ply cold-process modified bitumen roofing
Single-ply PVC membrane systems (Versico, Duro-Last)
Standing seam metal roof systems
Roof coating

Pacific West Roofing is a Taylor Metal Preferred Installer, trusted for premium metal roof replacements and installations across commercial buildings in Tualatin, South Salem, and Happy Valley.
