Chapter one
Clay tile roofs in a brickmaking village
Ringmer's brickfields supplied bricks and tiles for Stanmer House and the Glynde Place stables, so judging the age of a clay roof comes first.
Clay tile was made in this parish for centuries. The Sussex Industrial Archaeology Society records the parish as lying on gault clay, greensand and weald clay, thought to have been a pottery-making centre since the Norman Conquest, and its brickfields supplied bricks and tiles for Stanmer House and for the Glynde Place stables. None of that tells you what is on any one roof, but it explains why we judge the whole covering before we touch a single tile.
At a glance
- Marley reports a 60-year minimum for clay tile
- MyBuilder says clay tiles need replacing after 40 to 60 years
- Old peg-tile roofs cannot be judged by that figure alone

1.1 How old is the roof, really?
Published lifespans give a starting point and not a verdict. Marley reports a Building Research Establishment finding that roof tiles last at least 60 years, while MyBuilder says clay tiles need replacing after 40 to 60 years. For old peg-tile roofs, an article in the Building Conservation Directory calls that 60 a poor yardstick, since hand-made tiles vary a good deal from one to the next. So we do not read age off a table. We lift a few tiles, look at the underside for flaking, check the nibs, the small lugs that hook each tile over its batten, and test whether the nails still grip. Sound clay on tired fixings is a different job from clay that is failing across the slope.

1.2 Repair, re-fix or re-roof
Colour and texture matter as much as size. A new tile of the right dimensions but the wrong shade stands out for years, because clay weathers slowly, so we compare tiles in daylight on site before anything is ordered. Where the tiles are good, the answer is often to strip the slope, renew the battens and underlay, and lay the same tiles back, topping up with matching ones. Where tiles are flaking everywhere, a patch only delays the bill. Trouble gathered at one valley or one chimney tends to mean a repair; trouble on every slope tends to mean a new roof. We name the option we recommend and explain it with photographs taken on your own roof. Our roof repairs page sets out what a repair covers, and our roof replacement page covers a full re-cover. Tiles that come off a good roof are sorted by size and condition, so the best go back on the visible slopes and the rest are kept as spares for later repairs.
