Chapter one
Hung tile and weatherboard on refaced frames
A timber frame refaced in a later century has more joins between wall and roof than it was first built with.
Some of Rusper's humbler timber-framed buildings were refaced at a later date in brick, hanging tile or weatherboarding, as the Horsham District Council appraisal records. The refacing hides the frame, but it also hands the roof extra edges to seal, and those edges are where we start. Hanging tiles are small clay tiles hooked over battens on a wall, each held by a nib along its top edge. They overlap like a roof, so they shed rain the same way, yet they snap if stepped on and a slipped one is easy to miss from the lane. Where a tiled wall rises above a lower roof, a lead flashing, a folded strip cut into the wall and laid over the roof tiles, closes the gap. Once that strip lifts or splits, rainwater runs down behind the wall and turns up as a brown mark on a bedroom ceiling or a stair wall, a room away from the fault.
At a glance
- Refaced frames add wall-to-roof junctions
- Hanging tiles hook over battens on the wall
- Lifted lead often stains a ceiling elsewhere
1.1 Weatherboard and the abutment
Weatherboarding makes a different kind of junction. The boards overlap one another, and the roof covering has to finish against them without leaving a pocket for water to sit in. On a survey we check the boards for open joints, then look at how the roof tiles tuck in beside them and whether the soakers, the small bent pieces of lead that sit between courses of tiles, are still in place. We also walk the gable ends. A verge, the edge of a roof where it stops at a gable wall, takes the worst of a gale, and a verge bedded in mortar alone can work loose over the years while looking sound from the road.
1.2 What the repair involves
Most of this is repair rather than renewal. We lift the affected hanging tiles, replace any with broken nibs using matching tiles, renew the lead where it has failed and dress it into a cut joint in the brickwork, not a bead of sealant. Photographs of each stage on your own wall are taken before the tiles go back, so you can see what was behind them. The wider roof is covered on our pitched roofing page. If the ceiling stain has been there for some time, we also check the timbers behind the wall for softness, because damp that has run unseen for several winters can reach a wall plate before anyone notices.
Following water behind wall tiles
- Look inside We begin under the roof, where a stain or a damp timber shows how far the water has travelled.
- Test the lead The flashing where the wall tiles meet the roof is checked for lift, splits and open ends.
- Lift tiles A handful of hanging tiles come off so we can see the battens and the back of the wall.
- Photograph, then quote What we found goes into photographs, with a written quote for the smallest fix that holds.
