The ashgrid spacer system is an ideal component for the over roofing or over cladding of any building where the existing roofing or cladding has become unsightly beyond repair or an improvement in.

Overcladding asbestos roof.

This is a cost effective approach with an aesthetically pleasing and watertight result. By overcladding a roof additional weight will be added to the structure. This is especially true when it comes to asbestos cement roof coverings. However many asbestos roofs are built with concrete portals meaning the roof is supported by a small number of concrete arches.

Once fixed into place any of our roofing sheets whether that s box profile corrugated or tile effect roofing sheets can be fixed into position. When overcladding an asbestos cement roof it will also be necessary in most cases to include a layer of insulation to meet current day building regulations. The benefits of asbestos overcladding. The overcladding process also reduces the costly disposal of the existing asbestos roof sheeting that must be sent to licensed landfill.

This would then require an engineer to carry out structural calculations to ensure that the structure is capable of holding the additional weight. The overcladding of an asbestos roof is a cost effective roof refurbishment process that minimises the disruption at site. The overclad process involves fixing a quatro bar mini zed rail or steel grid tight bar through your existing roof into the purlins below. This means the new roof cannot get enough stability on top of the old one a common risk of over cladding.

At roofclad we strongly recommend not going down this route and replacing the roof instead. The first stage is to fix a framework to hold the metal sheets in place directly to the purlins underneath the asbestos cement roof sheets.
