Tile roofs can provide a home or business with added curb appeal and, if properly installed and maintained, tile roofs can provide storm water protection for many years. The Tile Roof Institute (http://tileroofing.org/about-tri/) was organized in the ’70’s to provide information about properly installing and repairing tile roofing materials.
In the normally dry climate of the southwest desert, many roofing contractors do not use metal flashing materials at walls or around roof penetrations, opting instead to use mortar for flashing materials. Mortar flashing requires routine periodic maintenance because it is not always properly installed, and it can crack or spall. Property owners should request their roofs to be inspected by qualified personnel on an annual basis, with repairs made as necessary to prevent storm water from migrating under the tiles.
