Tim H Posted May 5, 2007 Report Share Posted May 5, 2007 This is the first roof of this type that I have encountered. The 'butterfly' roof over the main structure drains onto a flat roof that covers an addition. There are some problems that are obvious, but I found no signs of leaks in the attic. The flat roof has extensive alligatoring, but I do not think that it is a built-up asphalt roof,but maybe a rolled roof that has been patched with asphalt. I think that the 'butterfly' roof is a modified bitumen, but I am really unsure. It is stretched like a trampoline over the valleys (not bonded with the decking), and has signs of ponding, along with some questionable flashing. When the client (pre-listing), can find a reputable roofer with flat/low pitch expertise, they are going to have it evaluated and repaired (or replaced). Any comments as to materials or improper design/installation would be appreciated.
