The short answer
Plain clay tiles, with thatch in the village's past. The character assessment lists plain tiles and thatch together and says tile replaced thatch over time. Many roofs are steep, small-tiled and double-lapped, which makes them durable but demanding to repair neatly.
Walk along Church Street with the assessment in mind and the layers of the village appear. Timber frames, rubblestone and brick walls carry roofs of plain tile, and in a few places the memory of thatch survives in the steepness of the slope.
Q1.1Why are plain tiles laid in so many overlapping layers?
A plain tile is small and flat, so rain cannot be shed by one layer alone. Each course overlaps the two below it, which means water passes over at least two thicknesses before it reaches the batten. That double lap is what makes a plain-tiled roof so watertight and so heavy, and it is why repairs mean lifting the tiles above the fault to reach the one beneath.
Q1.2Are the old tiles kept when a roof is stripped?
Sound ones can. We lift the tiles with care, sort them, discard any that are cracked, laminated or loose at the nib, and re-lay the best on the slope that faces the street. New hand-made tiles make up the numbers. Laying them again on fresh battens and underlay preserves the appearance of the roof, and where that does the job it avoids the cost of buying a whole new covering.
Q1.3Does a steep pitch make a roof harder to repair?
It does. Access needs scaffold with a proper working platform, and the tiles have to be handled on a steep slope without sliding. We plan the scaffold at the survey. Our pitched roofing page describes how a full re-cover is organised from start to finish.
Beneath the tiles, the underlay and battens matter just as much as the covering. A roof laid before breathable membranes were common may have no underlay at all, and that is worth correcting whenever the tiles come off. Cold roof spaces also need ventilation at the eaves and ridge, so we check that nothing, from insulation to old paint, has blocked the airflow that keeps the timbers dry.
