A well-maintained tile roof can last anywhere from 40 to over 100 years, with its exact lifespan depending on the material and level of care. Proper maintenance, which includes keeping the roof clean, free of debris, and performing routine repairs for any cracked tiles, is crucial for longevity. The lifespan varies significantly by tile type:

• Clay, terracotta, and slate tiles are highly durable and can last over 100 years.

• Concrete tiles typically last from 30 to 100 years.

• Metal tile roofs generally last between 40 and 70 years.

• Composite tile roofs have a lifespan of 20 to 50 years.

Be aware that maintenance for a tile roof can sometimes be more expensive than for an asphalt roof.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

A roof can collapse from a leak if the leak is left unattended long enough. A collapse will happen when the structural components of your roof become saturated with water over time. The roof deck or rafters can slowly weaken until they can no longer support the weight of your roof.

Tile and shingle roofs both have their pros and cons. In general, tile roofs are a larger upfront investment. In some cases, they can cost twice as much as shingles, but they last much longer and generally hold their value better than shingle roofs. Shingle roofs, on the other hand, are budget-friendly and quicker to install.
