Clay roofing has been around for a very long time. It’s still a very common roofing material, and this is much in part, due to the longevity of a clay roof. Clay has high thermal capacity. What this means is that it can store and absorb heat energy well. This will serve to save you money on heating and cooling.
Clay does not take damage from heavy rain, hail or other severe weather conditions as easily as other types of roofing materials will. It is also a protection from fire.
If you have decided to switch from a different, lighter roofing material to clay, you do need to make sure that you are prepared to pay extra for the installation. This is because your framing might not be built to handle the extra weight that would be involved. It is important that you have the roofing company you hire ascertain if you need to strengthen the existing structure before installing a heavy, clay roof.
