The church of St Saviour, with its red tile roof, shows how long clay can last when it is kept in order. A clay-tiled house nearby can do the same with regular care.
Q2.1How long does clay tile last?
Estimates vary. Marley quotes a BRE-determined minimum of 60 years, MyBuilder says clay tiles need replacing after 40 to 60 years, and a 2008 article in the Building Conservation Directory notes that some peg-tiled roofs have lasted for centuries, so 60 years is no ceiling. Workmanship, exposure and upkeep decide where one roof falls.
Q2.2When is a repair the wrong answer?
When the tiles themselves have given up. A tile that flakes, splits along its length or turns soft is finished, and patching around it only moves the leak. Also, if the battens are rotten across a whole slope, new tiles on old timber is false economy. Either way a re-cover gives better value, and the survey report spells that out.
Q2.3Can I keep my old tiles?
Where they are sound, yes. We strip a slope, sort the good tiles, replace the battens and underlay, then re-lay with the reclaimed tiles mixed with matching new ones. The weathered colour that makes a roof look settled stays with the house. Where tile has to be bought in, we choose it for its fit with the old ones, not for its price.
The written quote that comes after the survey covers the work your roof needs, not a guess at it.
