Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, Onslow Roofing & Maintenance handles flat roofing in Onslow with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.

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 IA UV exposure. It's the toughest flat roof membrane for everyday abuse.

Our Flat Roofing Process

1

Membrane Assessment

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.

2

Your Options

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.

3

Membrane Installation

Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.

4

Final Inspection

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.

Flat Roofing FAQ

TPO is more energy-efficient (reflective white) and has stronger seam welds. EPDM is proven over 50+ years and typically costs less. Both are solid choices. We recommend TPO for energy savings and EPDM for budget-conscious projects.

Yes. Semi-annual inspections checking seams, flashings, drains, and membrane condition prevent small issues from becoming expensive repairs. Drain clearing is especially important. Clogged drains cause ponding that damages the membrane.

A roof coating is a liquid-applied membrane, usually silicone or acrylic. That extends the life of an existing flat roof by 10-15 years. It works when the existing membrane and insulation are in reasonable shape. We core sample and moisture test to determine if your roof qualifies.
