[Greenbuilding] experience with Enviroshake?

[Keith Winston]

I don't have experience with Enviroshakes, so I don't know if it's a 
faulty product. But often roofing fails for a reason: wrong 
preparation/underlayment, wrong nailing, installed too tight, etc. The 
most likely thing that I can imagine might curl corners would be 
excessive heat and/or trapped moisture, which would tend to point 
towards faulty preparation.

Warmly, Keith
