40 year old BUR (Built Up Roof) Gravel roof is leaking and ponding water.
The BUR is fully bonded to the timber sarking and cannot be removed.
We installed a tapered timber frame and new plywood 15mm thick substrate and a 3 layer torchon membrane system with Green Mineral cap sheet and roof top breather vents.
