Plain clay tiles on Patching's older houses
A roof over a 17th-century frame is repaired with that frame in mind, because the old timber is the part you cannot easily replace.
Patching's village buildings include several timber-framed houses from the 17th century, some of them later cased in brick. Under a roof like that, the frame is the oldest part of the house and the part that suffers most when water gets in unseen. Arun's conservation area statement names brick, flint, plain clay tiles and natural slate as the principal materials, so a repair here normally means matching small plain tiles, set in overlapping rows and hung on battens, the narrow timber strips fixed across the rafters. Our first task is to find where the water is really entering, because a ceiling stain in an old house is rarely directly beneath the fault.
At a glance
- Several 17th-century timber-framed houses survive in the village
- Plain clay tiles are among the principal materials
- Eaves, valleys and old junctions fail first

1.1 Where old tile roofs let go
Plain tiles hang from small projecting nibs, and on a roof that has stood for generations the nails or pegs that steady them corrode and the battens soften. We look at the eaves first, where the lowest courses take the most water running down the slope, then at the valleys, the inside corners where two slopes join and both share a single run-off channel. Old roofs with later extensions have extra junctions, and each is a place where a flashing, the lead strip bridging roof and wall, may have lifted. From the loft we look for daylight, dark staining on the timbers and any damp on the plate the rafters sit on.

1.2 Repair, patch or re-tile
A few cracked tiles on a single slope amount to a repair, and that is the advice you get. If the battens are sound we lift the tiles, keep every good one and replace the failed ones with tiles of the right size and colour. If the fixings have gone across the whole roof, a patch buys little and a re-tile on new battens and underlay, the water-shedding sheet laid beneath the tiles, is the better course. Whichever applies, photographs of your roof travel with the quote, so you can see the reason for the work. We take the waste away and leave the garden as we found it.
Where a house has been cased in brick, the tiling often stops at a verge, the sloping outer edge of a gabled slope, bedded in mortar beside the old walling. A loose verge lets rain into the wall head, so we check it, then fix it back to stay put in a gale. Our pitched roofing page covers tile and slate roofs, and our roof replacement page covers a full re-tile.
How we survey an old Patching tile roof
- Ground check We scan the slopes and chimney for slipped, cracked or missing tiles.
- Close look We examine eaves, valleys and each wall junction up close.
- Loft We trace staining on the timbers back to its entry point.
- Photographs Your own roof is photographed, then the written quote follows.
