inspectorwill Posted June 11, 2011 Report Share Posted June 11, 2011 At first glance from a distance, this roof appeared to be a really aged thermoplastic type material. Upon closer look, it appeared to be more like a troweled tar that had been painted. The patterns around the plumbing and furnace vent along with the seams approximately 4' apart are the confused me. Thousands of roof inspections and never seen anything like it. Please check out the pics and any information is always appreciated.

Richard Moore Posted June 11, 2011 Report Share Posted June 11, 2011 Those seams look more like 3' apart to me, which would be in line with your common, basic mod-bit torch-down roof. That's what that appears to be (see photo). The white color is probably some low-end reflective coating that was applied some time after the fact.

inspectorwill Posted June 11, 2011 Author Report Share Posted June 11, 2011 Thanks Richard, You are right the spacing is 3' apart. I agree with the MB opinion but what threw me off is the surface is completely smooth. What looks like seams the length of the roof and lines around the flashings are not actually seams. They are completely smooth like an outline from a removed material. Where the paint was peeling, I probed the material and it was tar like about an 1/8" thick. Not like MB that is usually resistant to probing and has differential at the seams. Also, all the MB I know of is coated with granules. Thanks again for your input.

hausdok Posted June 11, 2011 Report Share Posted June 11, 2011 Hi, It looks like someone applied a really thick layer of some type of acrylic or urethane roof coating over a modbit or built-up roof and that the protective plastic layer is now failing. Time for a tear off, deck evaluation and repair and a new cover. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
