I think it's interesting looking at it from the other end - as a homeowner, I can tell you that roofing is an expensive proposition.
If this can be competitive with traditional roofing and have a longer life expectancy, I'd buy in a heartbeat.
It has the potential to displace thousands of tons of asphalt shingles per year with the equivalent of recyclable glass, which is pretty fantastic. The embodied energy of production for the tar hydrocarbons in current roofing materials are pretty nasty, and they don't just disappear when they wear out.
