What is a significant reason clay tile roofing is not suitable for the west coast?

Clay tile roofing is not considered suitable for the West Coast primarily because of its increased risk during earthquakes. The West Coast is seismically active, with frequent earthquakes that can pose a risk to various construction materials. Clay tiles, while durable, can be quite heavy and rigid, making them susceptible to cracking or breaking under the stress of seismic movement. This characteristic makes clay tile roofs less desirable in areas where earthquakes are a common concern, as the potential for significant damage can lead to increased repair costs and safety hazards.

Other factors such as maintenance costs, aesthetic appeal, and climate compatibility may play a role in roofing choices, but the unique seismic challenges of the West Coast highlight the critical concern with the structural integrity and performance of clay tiles during seismic events.
