Timber boarded roofs remain one of the easiest roofing systems to erect. A typical timber boarded roof construction comprises of a truss system with falls accommodating battens to which 25mm timber block board is nailed. The boards are but jointed and timber fillets are inserted in the corners where the board meets the brick or timber up-stand. Once the timber board is down, the system has to be waterproofed using a nail able underlay fixed to the board with clout nails and washers. This in turn will receive a torch on membrane 4mm thick applied to the bitumen primed underlay surface.

This system accommodates the increased movement experienced on timber boarded roofs. The underlay will take up approximately 90% of the movement and the waterproofing membrane will accommodate the rest. This system is quick and easy to complete but never the less requires proven expertise to master correctly. The waterproofing contractor must take into account all health and safety measures when working with timber and the gas torch.
