Long Term Field Test Results of Experimental EPDM and PUF Roofing

Abstract

Experimental roofs of single-ply ethylene-propylene -diene monomer (EPDM) and sprayed-in-place polyurethane foam (PUF) were installed during 1979 and 1980 at Fort Benning, GA and Fort Lewis, WA. This research documents the long term results of a field test program to evaluate the effects of aging/ weathering on the EPDM and PUF materials and the repairability of the surfaces. An EPDM membrane provides a satisfactory, watertight roof. Aging is directly related to the local climate. Current repair techniques for EPDM are satisfactory when proper materials and procedures are used. PUF roofs should give satisfactory service if repairs are properly made and the surface is periodically recoated as the original coating wears away. It is recommended that authorized roofing personnel be used or that installation personnel be trained by the roofing manufacturer to maintain and repair each type of roof system installed. Specifications for PUF roofing should be expanded to include urethane/Hypalon coating. (js)
