TWS are able to offer clients a system that now has an insulation and waterproof system in it. The lifetime of the product is 25 years and it also comes with BBA certification.
An example of a roof that TWS did is one that was 97 square metres wide. The old roof was removed as repairs were required underneath. The rafters were replaced with plywood and new PVC facia and soffit was put in place. The gutters and downpipes also had to be repaired. Once this was complete they were all insulated on the internal area and in order to prevent condensation build up a vent tray system was installed.
It took TWS five days in total to complete the work and now the owner is guaranteed a longer life in the new roof because of the system used.
