SlateTec installation – Genuine Slate, Less Weight! Beauty and longevity of a slate roof, but not the extra weight! The SlateTec slate roof system is an innovative lightweight approach to installing a genuine slate roof. Using their very rugged interlayment, a SlateTec roof uses far less slate overlap than in a traditional installation.

Cedar shake replacements and asphalt re-roofing solution. The SlateTec system will reduce roof weight roughly 40% because it requires less slate — the key to its cost effectiveness. The reduction of roof weight (less than six pounds per square foot) also lowers structural costs, contributing further to the system’s high value. You can upgrade to slate without the concern normally associated with a slate roof’s structural support requirements.
