Scottpat Posted November 28, 2007 Report Share Posted November 28, 2007 I found this yesterday. Roof was replaced about 14 months ago, it looks like a 10+ year old roof. About 75% of the shingles had marks on them and many looked like they were mashed or stepped on when they were hot. I have never seen this before.

Les Posted November 28, 2007 Report Share Posted November 28, 2007 Scott, have not seen that exact scenario, however it looks like it is a heat issue. What is the orientation of roof surface and what substrate? Did the house have a fire? A smoldering fire can soften and allow shingle to flatten or "melt" like that.

hausdok Posted November 28, 2007 Report Share Posted November 28, 2007 Hi, I've seen those. They're a 3-tab shingle that's made to simulate the look of an architectural grade cover without the cost of an architectural-grade cover. When one sees it from the ground and doesn't look at it closely, one thinks, "OK, there's at least a 25-year service life on that cover," then you look closer and realize that it's just another 20-year 3-tab. Instead of the extra tabs being laminated in place, they're molded into the surface. Put one of those on in hot weather, and I imagine that those fake tabs - which are just thickened asphalt - will squash all to hell when you walk on them. I've found them less than 10 years old where they were so worn at the edges that the fiberglass matting was showing through and the fake tabs were almost worn away from the weather.

Scottpat Posted November 28, 2007 Author Report Share Posted November 28, 2007 That is exactly what it is Mike! I thought it was an architectural-grade shingle until I got up on it. Anyone know who makes this type of shingle? Quote Link to comment Share on other sites More sharing options...
