**A tile roof lasts 50 years or more: the National Association of Home Builders puts clay and concrete tile roofs at over 50 years, and the Tile Roofing Industry Alliance says 50 to 100 years or more.** That figure describes the tiles. The underlayment beneath them, which keeps water out of the house, wears out sooner and decides when the roof needs real work. To have the underlayment and tiles on your roof checked, call NEMA Roofing at [866-631-3366](tel:866-631-3366).

## Clay tile roof lifespan vs concrete: how long does each last?

Neither source splits the two: both place clay and concrete tile in the longest-lasting group of roof coverings, alongside slate. They age differently, though, and that matters for how the roof looks and what upkeep it asks for.

|  | Clay tile | Concrete tile |
| --- | --- | --- |
| How it is made | Fired clay; glazed or matte ceramic finish | Cement, sand and pigment, molded |
| Surface over time | The industry group calls glazed or matte clay essentially maintenance-free | May show efflorescence, a white chalky bloom that is temporary and does not harm the tile; color may soften after long exposure |
| Main risk to the tile | Cracking from impact or foot traffic | Cracking from impact or foot traffic |
| Replacement pieces years later | Match by profile and color | Some concrete profiles are no longer made, which can make matching hard |

The Department of Defense roofing criteria (UFC 3-110-03) prefer clay and standard concrete tile and say to avoid lightweight concrete tile unless structure or appearance requires it, which is a useful hint if you are choosing a product for the longest service.

## Why the underlayment sets the real timeline

Tiles shed water; they are not a sealed surface. Wind-driven rain and water that finds its way past flashing get under them, and the Tile Roofing Industry Alliance’s installation manual calls the underlayment “critical to the success of the roof system” for that reason. The California Building Code specifies which underlayment types go under tile and requires two layers on pitches between 2.5 and 4 in 12.

When that layer wears out, the tiles do not have to go with it. The usual job takes the tiles up, puts down new underlayment and relays the same tiles. In the City of Los Angeles this scope is an Express Permit item, and LADBS exempts it from the cool-roof requirement. Two things can turn it into a full replacement:

- **Tiles that cannot be matched.** Broken pieces need replacements that interlock and seat with the old ones. If the profile is discontinued, the industry group lists harvesting tiles from a less visible roof plane or a full replacement as the options.
- **Code thresholds.** In some jurisdictions, replacing more than a set share of a roof brings the whole roof under current code.

## How long do tile roofs last in Southern California?

The same tile ages differently a few miles inland. NOAA’s 1991-2020 climate normals count about 115 days a year at or above 90 degrees at the Woodland Hills (Pierce College) station, against about 5 in Santa Barbara and about 2 in Oxnard. Heat matters less to the tile than to what lies under it: the underlayment and sealants take the heat and UV, and the industry group notes that intense heat, moisture or UV can damage roof components beyond the tile. On hot inland roofs, ask about a high-temperature underlayment, which the Defense criteria call for under tile in the extreme south and southwest of the country.

On the coast, the metal parts are the weak link. The building code requires corrosion-resistant tile fasteners and flashing; the Defense criteria go further, with stainless steel or copper fasteners and copper, lead or stainless flashing. Near salt air, the fastener and flashing metal is worth asking about on any quote.

## What shortens a tile roof’s life?

- **Broken tiles left in place.** A crack across the face exposes the underlayment to water and sun; the industry group says to replace broken tiles as soon as possible.
- **Foot traffic.** Most manufacturers do not warrant breakage from walking on the roof. Solar, HVAC and painting crews should step only on the supported lower edge of each tile or work from plywood.
- **Weak flashing** at walls, chimneys, skylights and valleys; the installation manual names water getting past flashing as one of the main causes of problems on tile roofs.
- **Debris in valleys and tile channels** that dams water and pushes it sideways under the tiles.
- **Low pitch without double underlayment**, which leaves one layer doing the work the code assigns to two.

Our guide to [common tile roof problems and how to fix them](https://nemaroofing.com/tile-roofing/common-tile-roof-problems-and-how-to-fix-them/) covers the repairs for each.

## Signs a tile roof is near the end of its life

- Leaks or ceiling stains after rain even though the tiles look intact, which points to the underlayment.
- Brittle, torn or crumbling underlayment visible at the eaves or around a lifted tile.
- Many slipped or cracked tiles in several areas rather than one damaged spot.
- Rust on flashing or fasteners, or sealant-only patches from earlier repairs.
- A discontinued tile profile, so repairs keep leaving mismatched patches.

An inspection sorts these into repair now, re-underlay and reset, or replace. The [tile roof inspection guide](https://nemaroofing.com/roof-inspection/santa-barbara-tile-roof-inspection-guide/) shows what an inspector checks, and if you are still choosing a material, compare [tile against shingles](https://nemaroofing.com/tile-roofing/tile-roof-vs-shingle-roof-which-is-better/).
