EPDM ROOFS

EPDM (ethylene propylene diene monomer) is essentially a synthetic rubber membrane roof that initially provides an economical roofing solution to building owners. These systems have a service life of 15 years and, as with single-ply, offers only one layer of protection. Reduction in service life can be caused by several issues: ponding water and its effects on the laps and seams are detrimental to the system; EPDM roofs, depending on age, are also prone to shrinkage; in some cases there can be shrinkage as much as 2% over the life of the roof which equates to movement in feet instead of inches; and this movement allows the laps and seams to become a source of water infiltration.

Thermo Manufacturing can provide a long-term, sustainable solution for difficult roofing conditions. The links below cover our standard recommended systems for EPDM roofs.

If actual project conditions are such as to be outside the scope of the normal waterproofing practices that are referenced in the documents below, steps should be taken to ensure the restoration remains in compliance with nationally recognized waterproofing practices such as those found in the National Roofing Contractors Association Manual. If the system is applied according to our published specification and guideline, and after successfully passing a final inspection, and then accepted by Thermo Manufacturing Systems, LLC, the system would qualify for the specified warranty.
