SlateTec & Vermont Slate.

SlateTec Lightweight Slate Roof

The SlateTec lightweight slate roof system is an innovative approach to installing a genuine slate roof. The secret to the patented SlateTec design is that we employ a very rugged interlayment on the roof deck that allows a 40% reduction in slate tile overlap. Therefore, a SlateTec roof uses far less slate than in a traditional installation. Along with the reduction in roof weight, the system uses 35-40% less slate. The reduction of roof weight (less than six pounds per square foot) also lowers structural costs, contributing further to the system’s high value.

The SlateTec system features genuine Greenstone Slate® in all the colors and grades of Vermont slate.
