EPDM Rubber Roofing SystemsResidential & Commercial Low-Slope Roofing

Flat roof additions, detached garages, and sunrooms represent a unique architectural challenge. Shingles require gravity to shed water. When shingles are laid on slopes less than 2:12, rain sits on the overlaps, capillary action pulls water backward, and freezing snow melt creates leaks. The right solution is a seamless, single-ply membrane system, and EPDM (Ethylene Propylene Diene Monomer) is a proven standard.

EPDM is a synthetic rubber compound that retains its flexibility in freezing temperatures, resists UV damage, and does not crack or tear under normal thermal expansion. EPDM systems are sensitive to installation errors: if seams are not primed properly or sheets are stretched during laydown, seams can pull apart over time. We apply a structural solvent-based primer to all seams before sealing them with double-sided seam tape. Installed in accordance with applicable manufacturer specifications, project requirements, and local building codes.

Every low-slope roof is different. Insulation and cover-board options are selected based on the existing roof assembly, drainage needs, project specifications, applicable energy requirements, manufacturer specifications, and local building codes. Where ponding is a concern, tapered insulation can be designed to direct water toward drains and gutters.
