EPDM Roofing
Done Right Since 1952
EPDM (ethylene propylene diene monomer) is a single-ply rubber roofing membrane that's been proving itself on commercial flat roofs for over 50 years. It's tough, flexible in cold temperatures, UV-stable, and economical. For the right application — particularly high-foot-traffic commercial buildings, budget-conscious projects, and cold-weather applications — EPDM remains the right answer. Keith Roofing has been installing EPDM since it became commercially available in the 1970s, and we're certified installers for Carlisle SynTec Sure-Seal, Firestone RubberGard, and Johns Manville EPDM systems.
EPDM differs from TPO in several important ways: EPDM is black rubber (though white EPDM is available at premium cost), uses glued or tape-seamed joints rather than heat-welded, and has substantially longer real-world track record (50+ years vs. TPO's 25+ years). For buildings where these attributes matter — rooftop equipment with foot traffic, cold-climate applications (EPDM remains flexible in cold where TPO can stiffen), or buildings where long-proven material is preferred — EPDM is a solid choice.
Our EPDM work covers commercial new installation, full replacement of aging BUR or mod-bit systems, re-cover installation over existing sound roofs, repair and patch work for existing EPDM systems, and coordination with property managers on multi-building portfolios.
