The existing roof system consisted of a ballasted EPDM membrane that was shrinking and tearing.  The rock ballast and the top layer of EPDM membrane was removed.  A layer of insulation was added and a new Duro-Last Roof System installed.  The existing skylight curbs were too low to the roof line to allow for proper flashing.  Our scope of work included raising the curbs and then flashing the curbs with prefabricated Duro-Last curb flashings.
