Independent testing at the University of Southern California has shown that clay and concrete tile roofing systems, when installed according to building code standards, exceed current seismic load requirements for building materials. Although earthquakes are not preventable or predictable, homeowners can lessen their impact through emergency planning and proper building design.Earthquake Testing
Tile is the only roofing product in the world to have been tested for seismic loading. Recently complete seismic testing, proves that roof tile could, in fact, withstand forces two to three times those generated by the 1994 Northridge, CA earthquake.
