For sheer lifespan, clay and concrete tile, metal, and slate lead the field. A tile roof can last fifty years or more, quality metal roofs run forty to seventy years, and slate can last even longer. Asphalt shingle, the most common choice, lasts more like fifteen to thirty years. The catch: on tile and slate, the waterproof underlayment underneath usually wears out before the tile does, so the roof needs attention long before the surface fails.
Tile is the classic California long-life roof. Clay and concrete tiles shrug off sun and hold up for decades, which is why so many older LA homes still wear their original tile. Metal is the other standout, since a good standing-seam metal roof resists sun, wind, and embers and can outlast the owner. Slate is the longest-lived of all, though its weight and cost make it rare. Each of these is a bigger upfront spend than shingle, but spread over their life, the cost per year is low.
The part people miss is that the tile or slate on top is not the whole roof. Beneath it sits the underlayment, the felt layer that actually keeps water out, and that layer ages faster than the tile. So a fifty-year tile roof often needs a reroof of the underlayment partway through, with the same tile lifted and reset. Our tile roof repair and metal roofing pages cover those systems.
| Material | Typical life |
|---|---|
| Slate | 75+ years |
| Clay or concrete tile | 50+ years |
| Metal (standing seam) | 40 to 70 years |
| Asphalt shingle | 15 to 30 years |
| Underlayment (under tile) | 20 to 40 years |
Our page on how long a roof lasts goes deeper on these ranges.
If you plan to stay in the home a long time, a tile or metal roof spreads its cost over many years and rarely needs replacing on your watch. If budget is tight or you may move sooner, quality shingle does the job for less. Whatever you pick, keeping up with the underlayment and small repairs is what actually gets you the full lifespan, which is where regular roof maintenance and a periodic roof inspection earn their keep.
