San Miguel panels are a synthetic replica of the clay tiles that come in sections approx. 1 meter by 1 meter, easily cut to shape and held down on metal support beneath with metal "U" clips and fastner. They are sold in most ferreterias, soltel, materialas ixtapa etc. Rapid installation and more likely durable in the event of an earthquake. I mounted my awnings that face the bay with a second metal support on top to hopefully hold it down in the event of hurricane winds.
