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. Dorset Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Dorset.
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 OH UV exposure. It's the toughest flat roof membrane for everyday abuse.
Our Flat Roofing Process
Membrane Assessment
Before recommending repair, coating, or replacement, we inspect the entire flat roof system. Membrane condition, insulation integrity, and drainage patterns all factor into our recommendation.
Detailed Proposal
Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.
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.
