Abstract
Experimental roofs of single-ply ethylene-propylene-diene monomer (EPDM) and sprayed-in-place polyurethane (PUF) were installed during 1979 & 80 at Ft. Benning, GA and Ft. Lewis, WA. This research documents the long term results of a field test program to evaluate the effects of aging/weathering on the EPDM & PUF materials and the repairability of the surfaces. An EPDM membrane provides a satisfactory, watertight roof. Aging is directly related to the local climate. ACurrent 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 reapir each type of roof system installed. Specifications for PUF roofing should be examined to include urethane/Hypalon coating. Additionally, studies should be done to evaluate the ability of newly applied foam to bond to that which is already in place, and to determine how long the bond can be expected to last.
