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. Gresham Roofing & Maintenance has the training and equipment to handle all of it across Gresham.
Our Commercial Roofing Process
Free Assessment
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Project 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.
Expert Crew
Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.
Warranty & Maintenance
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 Gresham Commercial Roofing Services
TPO is our most-installed commercial membrane in Gresham. White reflective surface for energy efficiency, hot-air welded seams that are stronger than the membrane itself, and 15-20 year manufacturer warranties. We install 60-mil and 80-mil systems, fully adhered or mechanically attached, over polyiso insulation.
