ASBESTOS ROOF OVERCLADDING
NOTE: This page is for information only.
As building surveyors, we do not supply or install overcladding systems.
The Process
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 first stage is to fix a framework to hold the metal sheets in place, directly to the purlins underneath the asbestos cement roof sheets.
The insulation is then installed into the framework (often an ashgrid system, so named after the original manufacturer, Ash & Lacy Construction) and the metal weather sheet is the fixed to a bar that acts in the same way as a purlin, to support the new roof sheets.
The end result will look just like a new roof, but without the asbestos disposal costs.
Budget around £100-120 per square metre.
Asbestos Roof Overcladding Cost
We often hear of contractors suggesting that they can overclad an asbestos roof for around the £40 per sq metre mark.
In every instance where we have tendered an overcladding project though, the quotes that come in are invariably in the £100-£120 region.
The reason for this is because when we specify overcladding projects, we take everything into account.
There are often costs that are hidden – usually concerning the stringent health and safety regulations that apply to this type of work, for example, internal or sacrificial safety netting.
Please note, whilst we can help manage your overcladding project, we do not install systems ourselves. This work requires specialist contractors.
