Modified Bitumen Roof System
U-Haul of Brockton had a tired EPDM roof system that was incorrectly installed by a national roofing contractor. Because the national roofing contractor issues their own warranties, they also write their own specifications, which, among other things, didn’t call for perimeter fastening. The result was that the membrane pulled away from the perimeter walls throughout the entire roof system, stretching and opening up the EPDM membrane along the way. This movement also created several wrinkles in the field of the roof, which created more points of weakness.
