[MassHistPres] does anyone know about EcoStar roofing?

[McClure, Veronica]

I am sending this query on behalf of a friend:
 
We need to replace the asphalt shingles on our roof and are wondering about EcoStar synthetic slate. We've heard it's supposed to be a 50-year roof and appropriate on a Queen Anne Victorian -- and probably expensive.
 
Has anyone used EcoStar or other synthetic slate?  Comments, suggestions?
 
Here's the EcoStar site:  http://www.ecostar.carlisle.com/index.html

Many thanks,

Veronica McClure
