We recently completed this project in Maryland! This Marriott Courtyard had an old EPDM membrane that was out of warranty and needed to be replaced. We removed the ballasted (literally a lot of pebbles!) EPDM and installed a mechanically fastened TPO system. In one of the areas we also had to rebuild the 9′ parapet walls due to the walls being previously built incorrectly. This job presented some challenges with unusual custom flashings built into the walls – but nothing the “beards” couldn’t handle!
