The short answer
Published guides put clay tiles at around 40 to 60 years, with Marley citing a BRE minimum of 60 years, and concrete tiles at 30 to 50 years, with Marley expecting around 60. These are typical ranges, not promises. On many roofs the battens, underlay and fixings wear out before the tiles do, so the support often sets the working life.
What the published guides say about clay and concrete
Lifespan figures for tiles come from several places, and they disagree with each other. The disagreement is informative, because it shows how much rests on the individual roof rather than on the product.
For clay, MyBuilder's slate roof guide (updated August 2026) says clay tiles need replacing after 40 to 60 years. Marley, a tile manufacturer, writes that the BRE gave clay tiles a minimum life expectancy of 60 years under its Green Guide profiling in 2008. CORC, a roofing contractors' trade body, says well-maintained clay can last 100 years or more. Old handmade roofs hung with wooden pegs have outlived that figure by centuries, which is why the Building Conservation Directory (2008) treats 60 years as a poor guide for historic buildings.
For concrete, MyBuilder says tiles typically need replacing after 30 to 50 years. Marley puts its own concrete tiles at around 60 years in service, then adds that the figure is no guarantee or warranty. CORC says 50 years or more. Reading the three together, concrete tiles often last 30 to 60 years, and the gap between them comes down to exposure, workmanship and upkeep.
Treat every number here as a typical range for a well-fitted roof. A manufacturer warranty is a separate matter and is not a prediction of how long your roof will last.
Why the parts under the tiles often fail first
A tile is a hard slab, fired or cast, with very little in it to wear out. What sits beneath is softer and far more exposed to damp.
Battens are the thin timber laths running across the rafters, and every tile hangs from one. Old ones rot where water has tracked in, or split around nail holes. Underlay is the sheet stretched over the rafters beneath the battens, there to catch whatever gets past the tiles. Bitumen felt on an older roof turns brittle, tears at its overlaps and droops between the rafters. Fixings are the nails and clips that pin each tile to its batten, and nails corrode while clips loosen.
This is why a covering may look fine from the lawn while the timber carrying it has little life left. Slipped tiles, lifting tiles and damp marks on loft timbers are frequently the first outward clues. Our page on why roof tiles slip goes into the common faults in more detail.
Signs a tiled roof is nearing the end
Begin outside on the ground, and borrow a pair of binoculars if you can. A dip along the ridge or between rafters, tiles that have dropped out of line, flaking or crumbling faces on concrete tiles, and a thick coat of moss that holds water are all worth noting down.
Next, carry a torch into the loft, and keep your weight on the boards rather than the ceiling below. Daylight showing through the covering, dark staining on timbers, damp insulation and underlay hanging in folds each point to trouble. A musty smell after rain suggests moisture is arriving somewhere.
None of this proves the roof needs replacing. One wet corner might trace back to a single failed flashing. The pattern is what counts: a fault in one place suggests a repair, whereas the same fault in many places suggests the whole roof is tiring.
Repair, partial strip or full re-roof?
Our habit is to quote only the work that settles the problem in front of us, and no more. Where battens and underlay are sound and a handful of tiles have failed, a repair is sensible and a re-roof would be money wasted. Where battens are going across a whole slope, new tiles pinned to tired timber will not last, and stripping that slope is the better route.
Re-covering also has a Building Regulations side. The Planning Portal sets two tests: under 25 per cent of the total building envelope and under 50 per cent of the roof affected. Cross either line and Building Regulations approval is needed, and extra insulation may be asked for too. At survey we say whereabouts your roof sits against those limits, and if the job turns out to be notifiable, the Building Regulations notification is something we deal with.
The survey gives you pictures from your own slopes and loft, and our quote is delivered in writing. Workmanship is covered by our 10-year guarantee in writing. To see what moves a price in either direction, read our tiled roof repair costs guide.
Getting more years from the roof you have
Most of the gain comes from small, regular checks. Keep the gutters flowing so water cannot back up beneath the lowest course of tiles, which is where leaf litter and moss tend to push it. Clear the valleys and the roof edges at the same time, because blocked channels spill sideways onto the underlay. Replace a slipped or cracked tile promptly, before water reaches the battens. Look at ridge and hip fixings after a storm, and have moss lifted off gently, since pressure washing can damage delicate tiles.
Pitch plays a part as well. A tile set at less than its minimum pitch lets wind-driven rain creep under the laps, and the roof ages quickly as a result. Our pages on how to measure roof pitch and the most economical roof pitch show how pitch and covering fit together. For the wider picture on this type of roof, see our pitched roofing hub.
Torn between mending and renewing? Send a few phone photographs of the loft timbers and the slope, and say when the last work was done. That tells us plenty before a ladder goes up, and it shapes what we look for on the day.
