ON AN EXISTING PROJECT, IS IT NECESSARY TO REMOVE THE OLD ROOF PRIOR TO THE INSTALLATION OF A NEW EPDM ROOFING SYSTEM?
Even though most exiting roofing materials are totally removed in most applications, an old and existing roof may be left in place once the manufacturer’s substrate preparations are followed. The existing roof and roof deck should, however, be inspected prior to re-roofing to ensure compatibility and structural integrity.
