EPDM is a synthetic rubber membrane used on low-slope roofs. Existing EPDM roofs can often be identified by their dark rubber surface and system-specific seams and flashing details.
Where This System Fits
EPDM is used on commercial and other low-slope roofs. Whether it is the right choice for a new project depends on design, drainage, system specification and owner priorities.
What We Evaluate Before Installation
We evaluate membrane condition, seams, patches, flashing, penetrations, substrate, insulation, drainage and signs of trapped moisture.
Installation Details Matter
The material name alone does not determine performance. Edges, transitions, penetrations, flashings, drainage and substrate conditions must be compatible with the selected system and installed as a complete assembly.
Repair or Replacement
A localized defect may be repairable when the surrounding system is in serviceable condition and compatible repair materials are available. Widespread deterioration, repeated leaks or substrate problems may justify replacement.
Important Considerations
EPDM repair materials and procedures differ from thermoplastic membranes such as TPO and PVC. Correct system identification matters before repair.
