Old frames beside the river Eden
Around Edenbridge the oldest houses stand on timber frames, so the first question on such a roof is what that frame is doing.
Edenbridge sits on the river Eden, close to the Surrey border. Hasted's history of Kent, written in 1797, says the river is formed from streams rising near Oxted and Lingfield, runs through the village and carries on east to meet the Medway at Penshurst. It also describes the surrounding farmhouses as old-fashioned timber buildings, standing singly and widely spread over stiff, moist clay, among broad hedgerows full of spreading oaks. Hamlets named Marsh Green, Stanford's End, Marlpit Hill and Medhurst Row lay nearby.
How do you judge a roof on an old timber frame?
We start from inside the loft, looking at the rafters, the sloping timbers that carry the covering, and at the wall plate, the timber bedded along the wall head where the rafters rest. A frame several centuries old has moved and settled, so a ridge that dips slightly may be perfectly sound. What worries us is recent movement: a slope that has sagged since the last repair, joints that have opened, or timber that is dark and soft beneath a valley, the trough where two slopes run into each other and carry water between them.
