Timber-framed houses and the roofs that sit on them
A roof on an oak frame has to move with the house, so repairs need to be light, matched and free to flex.
Shore House and Beckett's House on Tinhead Road, and Whites Farm on Inmead, are all timber-framed buildings of the late 16th century or about 1600. Their roofs sit on frames that have been settling for four hundred years. An oak frame is not rigid, and nor are the infill panels between its timbers. The whole structure shifts slightly with moisture, season and age, and any roof repair has to allow for that instead of fighting it.
The point where roof meets wall is the joint to watch. Rafters, or the heavier principal timbers, rest on a horizontal beam along the head of the wall. If rain has been running down that wall for years, the beam suffers first: it softens, it spreads, and the roof above it drops by a fraction. The lowest course of the covering then sits at the wrong angle, and the gutter, if there is one, no longer catches what comes off it. We look for that sag by sighting along the eaves line, then probe the timber with a blade to see how far the softness goes.
On a much-altered building like Shore House, the roof may have been raised, lowered, extended or opened up for later rooms, and each alteration left its own seam. The honest approach to such a house is to treat it as a collection of small roofs, mend each by its own rules, and keep a record of what was found.
Repairs follow three habits. Replace timber only where it has failed. Use lime, not cement, wherever mortar touches the frame or its infill, so the building can dry out. Keep the covering light and open to air. Our pitched roofing page explains the wider range of work on sloping roofs.
Any change to a listed timber-framed house goes to Wiltshire Council for consent before work begins. Careful recording of the old timbers is part of making that case.
