Chapter 1: Can the old peg tiles on a listed building in Farnham be repaired instead of replaced?
What we find
Peg tiles are fixed with a small wooden peg through a hole at the top of each tile, hooked over a batten (the narrow timber lath that carries the tiles). Over time the pegs rot or split, and the tile slides down. In the old centre you also find tiles whose faces frost has flaked away in thin layers, and ridge tiles that have worked loose from their bed. The timber structure beneath may be centuries old and sensitive to damp.
Because the town once produced its own tiles, the roofs here contain tiles of varied age and colour, patched in over the centuries. That patchwork is part of the look, and it is why a rushed full re-cover in modern tile spoils a roof that a careful repair would have kept. From the ground, the signs are gaps in the courses, tiles tilted outward and green staining under the eaves.
What we fix
Repair is normally the right route, and for a listed building it is often the only one the council will accept. We take off only the failed area, keep each sound tile, and fix replacements with new oak pegs or modern stainless fixings behind the scenes, depending on the building. Missing tiles are made up with reclaimed or hand-made plain tiles chosen to match the colour and camber. The ridge is reset on a bed that suits the age of the building.
Before we start, you get photographs and a written scope that you can show to the council's conservation officer, who should agree the plan if the building is listed. That keeps consent simple and avoids a stop-work order halfway through. For general options, see our pitched roofing page.
