For years, the roof tile industry has been asked to develop an
industry-based installation manual that would provide
recommendations for installing concrete and clay roof tile in
moderate climate regions of North America.
During the past two years, members of the Roof Tile Institute
(RTI) (formerly the National Tile Roofing Manufacturers
Association) have worked with the Western States Roofing
Contractors Association (WSRCA) to assemble such a manual, which
provides best installation practices, industry standards and
available code requirements.
The 73-page manual contains detailed recommendations and
drawings that address every aspect of roof systems used with tile
products. The recommendations are meant for areas with moderate
climates that may experience occasional winter storms and heavy
rain. In locations where the January mean temperature is 30 F (-1
C) or less or where ice damming occurs, RTI and WSRCA suggest
roofing professionals refer to the organizations' Concrete and
Clay Tile Roof Design Criteria Manual for Cold and Snow
Regions. (Copies may be ordered on RTI's Web site,
