Are temperature limitations associated with the installation of EPDM roofing system?
In accordance with ASTM standard D 746, EPDM membrane has a brittleness temperature of -49 F. While the membrane will remain flexible and pliable in extremely cold temperatures, adhesives, flashings and tapes should be kept at room temperature (hot boxes are usually used on the rooftop to rotate adhesive cans and rolls of flashing). Although roofing contractors may select not to work in sub-freezing temperatures due to safety concerns, many EPDM installations have taken place in temps below 20 F.
