We are in the process of building a new home in CA and are looking at several roofing alternatives. The house was designed for composite shingles, so we are limited to about 650 lbs per square without re-engineering the structure. What do you think of the Slate 2.0 product which has more exposure and a synthetic backing? Any thoughts about the smooth lighter weight slate that is 3/16 inches to 1/4 inches which is in the 600 to 700 lb per square weight range? Thanks for your reply.

A 3/16 to 1/4 inch slate has been the standard thickness for slate roofing in the United States for 150 years. It is an excellent way to construct a roof and will last a long time. We routinely do restoration work on roofs built in the 1880s with this thickness of slates (from Vermont quarries mostly, but also from Pennsylvania, New York and Virginia quarries).
