Abstract

See full text

A slate and tile roofing system includes a base layer of compliant roofing material and a series of tile fasteners fixed along a top portion of the roofing material. A series of weather barrier strips is attached to the series of fasteners and fixed to the roofing material. A series of slate tiles is semi-permanently mounted over the weather barriers to form a prefabricated tile roofing subassembly. The subassembly expedites and facilitates the installation of slate and tile roofs without the need for highly specialized labor.
