rlskfoster Posted October 21, 2006 Report Share Posted October 21, 2006 This was my first flat residential roof. Iv'e seen roll roofing on low slope applications and that is what this looked like to me,however, I have been reading and now I wonder if this is a modified bitumen. The roof had a crown that sloped to each side and the seams ran in the direction of the slope. Past leaks in the home but all appeared to be currently dry. Any thoughts on this. My client is aware of my limited knowledge on a flat roof and I told him I would do some research on the subject. I really thought I had taken more pictures.

Bill Kibbel Posted October 21, 2006 Report Share Posted October 21, 2006 It looks like mod bit. If you press your thumbnail into the edge of rolled, and then mod bit, you'll never have to ask again. Consider a publication about low slope roofing from the National Roofing Contractors Assoc. Many manufacturers (and expert witnesses) refer to NRCA specs. Local chapters of HI orgs should have covered mod bit by the mid-80s. I find many HIs (and installers) not familiar with this stuff. Might be time for the continuing ed. committees to revisit low slope roofs. ps. Bad, bad & bad parapet. Link to comment Share on other sites More sharing options...
homnspector Posted October 21, 2006 Report Share Posted October 21, 2006 Looks like torch down to me, and a crappy roofing job. All of the roll roofing I have seen is 36 inches with about 6 inches of overlap. That looks wider than 30 or 32 inches. Link to comment Share on other sites More sharing options...
kurt Posted October 21, 2006 Report Share Posted October 21, 2006 Granulated Mod Bit; can't get rolled to do what they're getting this stuff to do. Lots wrong.... 1) No termination bar/mechanical fastener @ the parapet; the stuff will peel & further destroy the (already crappy) parapet. 2) No kants in the corners & roof/wall junctions. 3) Flashing is all screwed up. 4) I'd bet a tooth the eave edge detail is wrong; they always are. I'm sure there's more, but that's a decent start. Go here. http://www.gaf.com/General/ProductsNew. ... %20Details Look @ all the flashing details for mod bit. Once you see how it's supposed to be done, it's real common sense stuff. Of course, don't expect to ever see it done right. I've looked @ approx. 6000 mod bit roofing systems, & I've never seen one, not even one, that had every detail right. A couple were pretty close, though...

Jim Katen Posted October 21, 2006 Report Share Posted October 21, 2006 I agree with everyone else. That's mod bit. It's a very poor job. The parapet in particular is a mess. The good part is that it's fixable - if you can find a roofer who knows what he's doing. - Jim Katen, Oregon Link to comment Share on other sites More sharing options...
rlskfoster Posted October 21, 2006 Author Report Share Posted October 21, 2006 Man you guys kill me! I worried that the pictures I had wouldn't give you enough to make any judgement or observations. I am going to go back this weekend (vacant) and really look this thing over. Client was pretty certain he was gonna need some roof work. Another reason why this place is the best. Thanks Ya'll, Buster Link to comment Share on other sites More sharing options...
Steven Hockstein Posted October 21, 2006 Report Share Posted October 21, 2006 For those that want to really know how low pitched roofing systems are supposed to be specified and installed there is a program offered in Denver. I went to it about 10 years ago and it was very useful. Additionally, I got to see Denver! http://www.jm.com/roofing_systems/2360.htm Check out the online training info as well. The introduction to commercial roofing systems provides a good basic lesson on the different systems with photos. http://www.jm.com/roofing_systems/2375.htm Link to comment Share on other sites More sharing options...
