The short answer
Wiltshire Council's community history describes most houses in the village and surrounding villages as rubble stone with a tile or slate roof, with stone-tiled roofs on the Manor House in West Yatton Lane. Newer homes add concrete and clay tiles, so the work ranges from slate repairs to stone tile refixing.
Yatton Keynell lies about four miles north-west of Chippenham, on the southern tongue of the Cotswolds. The building stock reflects that edge position: Cotswold stone traditions, but with tile and slate alongside the stone tiles.
Q1.1How does a tile or slate roof on rubble walls age?
Both coverings last a long time while the fixings behind them hold, and many of the faults we are called to are really fixing faults rather than covering faults. The trouble tends to be nails that rust through, battens that soften, and lead flashings at chimneys that crack. On a slate roof, a slate slides when its nail fails. On a tiled roof, tiles crack or lift where frost has got behind them, and ridge tiles loosen when old bedding crumbles. Our slate roofing page covers the slate side in more depth.
Q1.2What sets the stone-tiled roofs apart?
A stone-tiled roof is far heavier than slate or tile, and it is laid in diminishing courses. Cotswold District Council's stone slate guidance gives about 1000 kg per 10 square metres. The roof structure is built for that load, so changing to a lighter material alters how the frame behaves, while laying stone on timbers designed for slate risks overloading them. Either way, we check the timbers first.
Q1.3What do we look at on a first visit?
We look at the ridge line, the verges, the valleys and the chimney flashings, then the underside from inside the loft if we can reach it. Daylight through the covering, stained rafters and softened battens tell us more than the surface does, and we note each one down with a photograph so you can see exactly what we saw.
Our aim is the minimum work that genuinely stops the leak. Where a section of covering is beyond saving, we replace that section in a matching material and leave the rest of the roof alone.
