How Long Does a Roof Last? (And Signs You Need a New One)
Short answer: a concrete tile roof typically lasts 50 years or more, clay tiles and natural slate can last much longer, and an EPDM rubber flat roof lasts 20 to 30 years or more. In practice, though, the tiles often outlast what's underneath them. The felt, battens and mortar usually fail first, and that's what most re-roofs are really about.
How long each type of roof lasts
- Concrete tiles: typically 50 years or more
- Clay tiles: typically 60 years or more
- Natural slate: often 80 to 100 years or more
- EPDM rubber flat roof: 20 to 30 years or more
- Old-style felt flat roof: 10 to 15 years
- Mortar ridges and verges: usually need attention every 15 to 25 years
Why roofs fail before the tiles do
Many Doncaster houses still have their original bitumen felt under the tiles. Over the decades it goes brittle and tears, especially at the bottom of the roof, so any water that gets past the tiles goes straight into the loft instead of the gutter. Battens rot, nails rust, and tiles start to slip. Mortar on ridges and verges cracks and washes out. At that point, replacing the tiles one at a time doesn't fix the real problem.
Signs you need a new roof
- Tiles slipping in more than one place, and coming back every winter
- Daylight or torn, brittle felt visible in the loft
- Damp patches, stains or drips in the loft after rain
- A dipping or sagging roofline
- Ridge tiles loose or mortar falling out along the whole ridge
- You're paying for repairs most years
Repair or replace?
If the problem is in one area and the felt and battens are sound, a repair is the right answer. If you're seeing several of the signs above, a new roof is usually cheaper in the long run. Most re-roofs we do in Doncaster cost £6,000 to £9,000 including VAT, and come with our 10-year guarantee.

Frequently asked questions
How long does a concrete tile roof last in the UK?
Concrete tiles themselves typically last 50 years or more. The felt and battens underneath often need replacing before the tiles wear out.
How do I know if my roof needs replacing?
Look for slipped tiles in several places, torn or brittle felt in the loft, damp after rain, a sagging roofline, or repairs every year. If you're not sure, we'll inspect it for free and tell you honestly.
Can you just replace the felt?
Not on its own. To replace the felt the tiles and battens have to come off, so it's normally done as part of a re-roof, often reusing sound tiles where they're suitable.
