That's interesting, Pop. Here in Tuscon the majority of roofs are flat (no snow) and I've never seen the EDPM product advertised or in use. (It's possible I haven't been paying attention.)
The flat roofs here are constructed two ways:
1. Gravel over asphalt - a VERY poor roof, that needs re-coating often and is prone to leaks.
2. Built up rolled roofing material, often the same material I think as shingles, but in wide sheets, or, a "composition" sheeting. This must be coated with the elastomeric paint, but then it is highly reflective and lasts almost indefinitely. The seams are all sealed and wind will not blow sections of it off like shingles. It is also relatively impervious to hail, although I'm sure big enough hail would cause damage.
People outside of Arizona generally don't know what I'm talking about when I speak of a built-up, composition roof like ours.
