How Long Does A Tile Roof Last?
QUICK ANSWER
Tile roofs last 50 years or more, with clay tiles often exceeding 100 years and concrete tiles 50 to 70 years. The tiles themselves outlast the underlayment beneath them, which needs replacement every 20 to 30 years even if the tiles are fine.
Tile roofs are among the longest-lasting roofing options available. Clay and concrete tiles handle heat, sun, and weather better than almost any other material. The tradeoff is heavy weight, which means the framing has to support them, and the fact that the waterproof underlayment beneath the tiles fails long before the tiles themselves. Here is what to actually expect from a tile roof.
How long do clay tiles last specifically?
Clay roof tiles routinely last 75 to 100 years, and many historic clay tile roofs in Europe and the American Southwest are well over a century old and still functional. The fired clay material is essentially terra cotta and resists UV, heat, fire, and weather better than nearly any roofing option. Spanish tile, Mission tile, and barrel tile are all clay variants. The only common failure mode is cracking from impact (a fallen branch, hail) or freeze-thaw cycles in cold climates, which is why clay is most common in warm regions.
How long do concrete tiles last?
Concrete tiles last 50 to 70 years on average, less than clay but still much longer than asphalt or wood. Concrete is heavier than clay and slightly less weather-resistant, with some color fade over time as the surface coating wears. Concrete tile is more common than clay in new construction because it costs less and offers more design options. In hot southwestern climates, concrete tiles can last 50 years easily. In freeze-thaw climates, expect closer to 40 years before tile damage starts.
Why does the underlayment fail before the tiles?
Beneath every tile roof is a layer of waterproof underlayment, usually felt paper or a synthetic membrane, that actually keeps water out of the house. The tiles shed the bulk of the rain but small amounts of water get past them every storm. The underlayment catches that water. Felt underlayment lasts about 20 to 30 years. Synthetic underlayment lasts 50 years or more. When the underlayment fails, water leaks into the house even though the tiles still look perfect. A re-roof on tile usually means removing and replacing the underlayment while reusing the original tiles.
Do tile roofs need maintenance to last that long?
Tile roofs need less maintenance than most options but not zero. Inspect annually for cracked or slipped tiles and replace any broken ones immediately to prevent water from reaching the underlayment. Keep gutters clean and trim back overhanging branches that could fall on the tiles. Avoid walking on tiles whenever possible since foot traffic cracks them, especially older clay tiles. A professional roof inspection every five years catches the issues a homeowner cannot see from the ground, and is well worth the small cost.
Tile roofs are essentially permanent if the tiles themselves stay intact. Clay lasts 75 to 100 years and concrete 50 to 70. Plan to replace the underlayment beneath the tiles every 20 to 30 years for felt and 50 years for synthetic. With annual inspections, the original tiles often outlast the house they were installed on.
