Slate Roofing Projects by Chubb Roofing Contractors
Branscombe Village Hall
Chubb Roofing Contractors were asked to provide a new roof covering in natural slate to the main premises and high performance membrane to all flat roof areas.
Once stripped of all asbestos sheeting, the roof structure was adapted to suit a slate covering. This was done by securing a system of steel supports and plates to the 5 x `A' frames and introducing cut 3x2 rafters fixed to the current purlin system. The new structure was covered with Marley TX breathable membrane. 2x1 treated battens were fixed in place using galvanised nails and set to a gauge of 200mm. The roof was then covered with 5OOmm x 250mm natural Brazilian green/grey slate with slate and a half at the verges. The slates were fixed using 38mm copper nails. All asbestos sheeting was removed from site under controlled conditions with the necessary Environmental Agency licence. The roof was crowned using grey ridge tiles incorporated with a ventilated dry ridge system.
The flat roof areas were stripped of their bitumen coverings and all chipboard decking removed. Insulation was fitted to the customers specification and 18mm Sterling board were fixed to the original ceiling joists. Rhepanol FK single ply membrane was stuck to the decking using adhesive and all flashing details fitted at the perimeter edges and upstands. Lead flashing were fixed into a cut chase at the abutment and sealed using lead sealant.
The original timber fascia boards were removed and replaced with white PVCu Mega board with all joins and corners. All rainwater goods were replaced including downpipes with a plastic deep flow rainwater system.
Chubb Roofing Contractors were extremely pleased to win this contract as the tender process involved competing against five other roofing companies.
