I would prefer to use the Chateau's.
Maine Winters seem to not cause problems with them
Thanks for the response. That's what we'll do.
Here in the northern Adirondacks of upstate NY, local roofers say the fiberglass composition shingles, no matter how heavy, don't hold up to the ice, and the freeze-thaw cycles of later winter and early spring, as well as the all organic ones. I guess that is why all the yards are stocking almost nothing but the IKO lines.
