Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Port Gamble Roofing & Maintenance has the training and equipment to handle all of it across Port Gamble.
Our Commercial Roofing Process
Building Inspection
We inspect the entire commercial roof: membrane condition, seam integrity, flashing details, penetration seals, drain function, and insulation condition. Core samples reveal moisture levels in the existing system. You receive a detailed written report.
Detailed Proposal
Your proposal includes material specifications, installation method, warranty terms, project timeline, and total cost. We itemize everything and explain why we're recommending the specific system for your building.
Commercial Installation
Our commercial crew installs per manufacturer specifications and NRCA guidelines. Hot-air welded TPO seams tested with a probe at every joint. Flashing details custom-fabricated for your building's penetrations. Insulation installed to achieve minimum R-value per code.
Warranty Activation
Final roof inspection with photo documentation. Warranty paperwork provided. We recommend an annual maintenance plan to catch issues early and maintain warranty compliance.

About Our Port Gamble Commercial Roofing Services
Ponding water is the number one cause of commercial roof failure. Water that doesn't drain within 48 hours degrades the membrane and insulation underneath. Port Gamble Roofing & Maintenance installs tapered insulation systems that create positive drainage to scuppers, drains, or roof edges, minimum quarter-inch per foot slope.
We offer annual and semi-annual maintenance contracts for Port Gamble building owners. Regular inspection catches small problems before they become expensive emergencies. Seam checks, flashing inspection, drain clearing, and minor repairs, all documented with photos in a maintenance report.
