[MassHistPres] Enviroshake composite roofing

[Colleen Chapin]

 While the Enviroshake product is advertised to be long lasting, it doesn't
truly replicate the appearance of a traditional wood shingle roof in this
area. Typically, a wood shingle roof would have a nominal exposure of
4"-5", be less than 1/2" thick at the butt and taper to zero at the tapered
end.  With a quick scan of the Enviroshake website, I see that their
product is installed with a reveal of 9" to weather. It's 1/2" thick at the
butt and an 1/8" at the tapered end. It also appears to mimic the rough
surface of an undressed shingle (i.e. smooth faced sawn wood shingle). With
such a difference in exposure, it might also create some challenges with
how the roof lays out with things like dormers or roof/wall intersections.
These are details that may be worth the Commission's consideration.
