The System

Developed by Stanley Ward of Stewartstown, Pennsylvania, the Slate Savers system was over 20 years in the making. The system is now patented.

Presented with the problem of repairing a slate roof in a manner which would virtually renew the life of the roof without having to replace the original slate,
Mr. Ward began experimenting with various adhesives, caulks, and chemicals
to find just the right formula that could provide a permanent repair solution
without compromising the beauty or integrity of the original roof.

Field tested for over ten years, the final product, a breathable, weatherproof polymer caulk that is able to expand and contract with the changing seasons, is
only part of an entire system designed to extend the life of slate roofs for another 40 to 60 years.  The system adds a level of structural integrity to the slate roof which permits debris removal or individual tile replacement with little effect or damage to other tiles.
