This sun room roof had definitely seen better days, in spite of multiple attempts over the years to patch it up. When replacement became necessary, the homeowner’s wishlist included energy efficiency in the room below as well as getting the new roof approved for the Maryland Historic Tax Credit. He received MHT approval for our quote, and we moved forward! Beginning with removal of water-damaged wood, we then installed insulation between the joists, where there had been none previously. Then new plywood decking and white aluminum flashings went on, followed by white TPO roof membrane. Finally, we placed a few protective EPDM ‘walking pads’ on the new surface, for the homeowner to step out on the roof area safely on occasion.
