Has anyone come across the term "crazing" when referring to a rubber roof? I have a rubber roof on my 1999 Damon Challenger and I wondered what it was. Even money suggests it is not good !
I have often referred to the deterioration of the top layer of material on EPDM as crazing. Shortly after it will start sluffing off exposing the black layer. It is perfectly normal for EPDM to do so as it ages. It does not necessarily mean there is a problem, simply the aging of the material. In this case the roof is 14 years old. EPDM has a normal service life of 20 years but many have extended it by recoating with a compatible material.
