QUESTION:How long do clay roofing tiles last?
ANSWER: They really don’t know.
Clay roofing tiles date back to Neolithic China. And since many ancient structures with clay roofing tiles still exist today, it is difficult to come up with an accurate expiration date or shelf-life.
The rule-of-thumb is that clay roofing tiles cost about three times as much as asphalt shingles and can be expected to outlast the building it protects.
