Flat and low-slope roofs need a membrane system matched to the building, budget, and how the roof will be used. SwiftBuild installs all four major systems — here's how they compare.
Rubber membrane roofing — cost-effective, proven, and easy to repair.
⬜Reflective, energy-efficient single-ply membrane with heat-welded seams.
💧Liquid-applied, fully seamless membrane — ideal for complex roof details.
🔥Multi-ply asphalt-based system, torch-applied or self-adhered.
🏢Flat roofing scaled for commercial buildings and multi-family properties.
🏙️Flat roof systems sized for Brooklyn and Queens brownstones and rowhouses.
The membrane is only as good as the installation underneath it.
Every flat roof system has its own seam, fastening, and flashing requirements — we follow them exactly.
