All Saints, Graveney

All Saints, Graveney is a Grade I listed Church with the earliest fabric dating from the Norman period. The church is constructed of Ragstone and flint walling, with window surrounds formed of Caen stone.

The challenge

Serious defects were identified to the north and south aisle roofs, with the asphalt roof covering showing evidence of cracking and movement, an indication that it had reached the end of its useful life.

Our solution

The timber substrate and ceiling joists underneath the asphalt appeared to be rotting as a result of water ingress and ‘sweating’ due to the impermeable asphalt causing moisture to build up and rot the structural timbers underneath. In addition, the asphalt could not be properly flashed into the parapet walling resulting in considerable water ingress causing damage to the walling plaster internally.

The results

The PCC obtained a grant from the HLF and a generous grant from the Friends of Kent Churches to enable works to repair and recover both the north and south aisle roofs. Clague prepared a specification and schedule of works for the repair of the structural timbers including the recovering of the aisle roof in zinc, rather than lead. This was agreed due to the isolated location of the church and the previous record of theft from the church. The works included strengthening the existing beams with new sections of steel to ensure the existing timbers could remain in-situ whilst sections of rotten timbers were removed with new sections of oak carefully scarfed in.
