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. Covina Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Covina.
TPO is our most-installed flat roof membrane. White reflective surface reduces cooling costs, hot-air welded seams create a watertight bond stronger than the membrane itself, and manufacturer warranties run 15-20 years. We install 60-mil and 80-mil TPO, fully adhered or mechanically attached over polyiso insulation.
Our Flat Roofing Process
Free Evaluation
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.
System Recommendation
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.
Expert Flat Roof Crew
Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.
Warranty & Drainage Test
Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.

Why Choose Covina Roofing & Maintenance for Flat Roofing?
Core Sampling & Testing
Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.
Manufacturer Warranties
15-20 year manufacturer warranties on new flat roof installations. Coating systems warrantied for 10-15 years. All backed by certified installation.
Drainage Solutions
We solve ponding water with tapered insulation systems. Minimum quarter-inch per foot slope to drains or edges. Ponding is the number one flat roof killer. We eliminate it.
Electronic Leak Detection
We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.
