MPdesign Posted November 8, 2012 Report Share Posted November 8, 2012 This appears to be layers of roofing felt with most of the roll overlapped except for the last 8" of the sheet. Then it is cool coat mopped. If anyone has any actual data on what this type of roof actually is, please let me know. I have seen thousands of roofs and the above is a pretty good description of what it really is.... Believe it or not - they have a warranty on it.

hausdok Posted November 8, 2012 Report Share Posted November 8, 2012 It's glass mat. I see it all the time. It's supposed to be used to isolate a single-ply membrane from stuff underneath but some roofers mop it to create a really cheap single-ply roof. Around here they never lap it that much - usually no more than about ten inches. According to Jorve Roofing, a big roofing company here, those last about 5 to 8 years before they're toast.

MPdesign Posted November 8, 2012 Author Report Share Posted November 8, 2012 I owe you a coke. Thanks! They have a 15 year warranty. There is no way it will last that long. Okay - hold on a minute. I am looking up glass mat to learn more about it and I see what is called glass mat boards. Please confirm that you are not talking about boards (I'm sure you aren't - but just rechecking). This is roll roofing- about the thickness of felt. Thanks! Link to comment Share on other sites More sharing options...
hausdok Posted November 8, 2012 Report Share Posted November 8, 2012 Yep, It's a glass reinforced asphaltic paper that's designed to be used as underlayment. Some roofers have been putting it down like a torchdown but without the heat and with asphalt cement. Mop coat, roll it in, finish covering the roof and then mop a layer of asphalt over the top and call it a day. Cheap roof made with materials not designed for that purpose. Another word for it -- jackleg. ONE TEAM - ONE FIGHT!!! Mike Link to comment Share on other sites More sharing options...
