Product Description
The Tile Roofing Institute (TRI) is the premier resource for technical information on the proper design andinstallation of concrete and clay roof tile systems. The Tile Roofing Institute in partnership with the
Western States Roofing Contractors Association (WSRCA) assembled a task group in 1991 to develop an
installation manual that would provide a representation of proper installation practices, industry standards,
and code requirements. These recommendations have provided successful installations of roof tile which
have endured the test of time.
