Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Mckenna Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Mckenna.
Our Flat Roofing Process
Flat Roof Inspection
Our inspector checks every detail: ponding areas, seam separations, flashing failures, clogged drains, UV degradation, and blistering. Core samples test insulation moisture content. You get photos and an honest assessment.
Detailed Proposal
Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.
Professional Installation
Our flat roof crew installs per manufacturer specifications and NRCA guidelines. TPO seams hot-air welded and probe-tested. Modified bitumen torch-applied in two plies. EPDM fully adhered with proper lap adhesive. Tapered insulation installed to create positive drainage.
Completion & Warranty
After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

About Our Mckenna Flat Roofing Services
Modified bitumen is our recommendation for residential flat roofs and high-traffic commercial applications. Two-ply torch-applied SBS system with a granulated cap sheet handles foot traffic, thermal cycling, and WA UV exposure. It's the toughest flat roof membrane for everyday abuse.
Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
