Deckert, Annie From: Ruprecht, Bob Sent: Monday, July 25, 2011 3:26 PM To: Deckert, Annie Cc: Ruprecht, Bob Subject: 716-720 Main St. Annie, I visited the Arts Alliance and Auto parts store(716 and 720 Main St) on July 13, 2011 to look at some roof problems and the potential repairs. The rubber membrane roof on both buildings is in very poor condition. The insulation board under the rubber membrane of the flat roofed Art building appears to be completely saturated with water. There have been multiple patches placed on the existing membrane and it is very difficult to see which of the patches are failing. The only sure fix would be to take the existing membrane off completely to the decking, re-insulate and apply a new membrane that would extend partially up the parapet walls. More patching could possibly slow the leaks but would need to be done soon as to not fight the cold and snow. The rounded, barn style roof of the parts store also has a rubber membrane roof with multiple leaks that are difficult to follow. The membrane has shrunk substantially away from the side walls and would be very difficult to repair. A new membrane on this roof would also be recommended. I also looked at the inside roof framing members. It is a hand framed type construction and some of the frame members are fractured. I believe this is a more serious issue as a substantial snow load could cause a partial collapse. The roof has a substantial sag and I would recommend a structural engineer to design a repair. At minimum the snow should be removed on a regular basis to minimize the risk of a collapse. Feel free to contact me with any questions you may have. Bob R.
