Service Carried Out By Roofclad


Roofclad were instructed to remove the existing asbestos cement roof sheets and rooflights, then to replace them with a new double skin, insulated system.

Client Problems


The asbestos cement roofs on units 2-9 at Station Lane were in a poor state of repair. The client wanted the units to all be fully updated and to be more appealing to potential tenants. As well as being more appealing the client wanted the roofs to be free from asbestos.



Roofclad Systems set about the task by having a triple handrail scaffold erected to all exposed roof edges in accordance with the Working at Height Regulations. In addition to this, a scaffold access tower to eaves level with fixed ladder access was also erected. A plain safe/debris netting system was put in place below the roof, in accordance with the recommendations of EN1263-2. All connections were knotted round primary truss members, temporary support ropes or other suitable anchorages.

Work commenced on the roofs unit by unit with the safe removal of all existing asbestos cement sheeting and plasterboard lining, together with all GRP rooflights. Roofclad Systems installed a double skin, insulated roof to give a U value of 0.18w/M2K. The system consists of a 0.7mm thick profiled white faced liner, fixed to the existing purlins using self-drilling screws. Our operatives then secured lightweight galvanised steel ribbed support bars using carbon steel self-drilling screws. The metal liner was overlaid with 240mm glassfibre insulation. An external 0.7mm thick, 34mm deep profile, galvanised steel embossed plastisol coated sheet was secured using nylon headed self-drilling stainless steel fasteners and stitchers.

Incorporated into the roof area were 10%, site assembled double skin rooflights to comply with HSE recommendations of non-fragile rooflights. This consisted of 2.4Kg Class 1 inner skin with a 1.8Kg Class 3 outer skin.

In addition to the roof works, approximately 265 lm of gutter replacement work was carried out. A 0.7mm ‘Trimeline’ style gutter was supplied and fixed to the eaves complete with stop-ends and outlets. To complete the project, 110mm rainwater downpipes including brackets, shoes and fixings were supplied and fixed.
