Big Green: White TPO vs EPDM and paint

[Dean Sherwin]

Are you looking for a cost study or a study of reflective performance?

The comparative cost is going to depend on the labor rates at the 
location in question.
In general, anything that has to be re-done every few years is not 
going to be as efficient, as regards cost and resources.  High labor 
rates will exacerbate this.
More roofing-experienced people correct me, but I do not think we yet 
know the comparitive longevity of  TPO, which is fairly new as a 
popular roof, as compared to EPDM .  Given the underlying polymer 
technology my gut feeling is still that it is not going to be as long lasting.
