According to many studies and actual cases, the expected lifespan of Roman clay tiles is generally between 50 and 100 years, or even longer. This lifespan far exceeds that of many other roofing materials, such as asphalt tiles and metal tiles.

High-quality clay tiles can withstand a static weight of about 150-200 kilograms per square meter when laid reasonably. This load-bearing capacity is mainly used to resist natural loads such as snow accumulation and falling branches.
