Removing & replacing your Onduline roof

Yes as the roof structure is by its nature set out ready to accept new replacement Onduline sheets, just check  the roof structure for any deterioration and make good as required then fix new Onduline roofing in accordance with the fixing instructions.

Also consider any repairs or roofing improvements to the supporting structure such as providing a decked roof on the existing purlins. You might also look at changing your existing Onduline roofing type or colour and incorporate additional insulation; our technical sales department will be pleased to assist you with your project.

Never assume a roof will accept your weight, so always work from suitable platforms, establishing a safe method of roof access allowing you to safely lift and remove the sheets from the roof. This can often requires harnesses and fall-arrest lanyards to be worn.

You must establish an effective means of keeping people and work colleagues from the below the area you are working, this might also require areas to be secured by safety netting below the working area. Organise a safe method of removing the old sheets from the roof to a storage area; or disposal skip.

Avoid storing materials on the roof; or on scaffolding platforms, waste materials must never be thrown from the roof, they should be removed by hoists; or similar approved methods.

No, evidence is found of adverse eco toxicity. Low ecological toxicity is therefore estimated. There is no known adverse effect to the environment because of its usage or application. Onduline is a classified a green product as it is manufactured using 50% recycled materials in the production of the sheets.

If the sheets are being disposed of at local refuse recycling centres consideration should be given to their efficient handling. We therefore recommend sheets are cut nominally into 500 mm strips to ease handling and ensure they do not cause problems with refuse compaction machinery.

When removing nails from Onduline sheets use a board laid across the adjoining sheet corrugations, this forms a stable leverage point when removing fixings with a claw hammer or crow bar.

Onduline is manufactured from 50% recycled cellulose fibre material, it is produced in modern environmentally efficient manufacturing plants which utilise industry leading technology to both recycle production energy and eliminate both airborne and water pollution.

Onduline contains no asbestos and presents no known health risk in handling, fixing or in service. It forms inert waste which can be safely disposed of in landfill and will decompose naturally to its constituent elements without presenting any known hazardous contamination risk.
