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. West Portsmouth Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout West Portsmouth.
PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in West Portsmouth, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.
Our Flat Roofing Process
Flat Roof Inspection
We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.
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.
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.
Final Inspection
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.
