I just wanted to share our experience of Onduline roofing and National Stables. (forewarned is forearmed)
National Stables erected a set of stables for us with an Onduline roof in 2001.
The roof stated leaking at around 7-8 years after it was installed. After 10 years the roof gradually started sagging along the whole length of the stables to a point that it has resulted in pooling of water in the sheets and more leaking. The sheets are stained black underneath and rotten.
They are attached straight onto the purlins, nothing underneath. After reviewing the manufactures fitting instructions and checking the measurements it looks like National Stables may not have followed them correctly. Our roof looks exactly the same as the 2nd and 3rd picture on this web page: http://www.stablerepair.co.uk/roof-problems/4574850634
On checking the Onduline warranty, it is guaranteed to remain weather proof for 15 years but only fully covered for the first 5. After that point their liability limited to a pro-rata replacement value. If they are confident that their product will last why is it only fully covered for 5 years? According to National Stables this product has an expected life span of only 15 years! http://www.onduline.co.uk/PDF/Onduli... General.pdf
Other people we have spoken to have said that they have had bad experiences with Onduline sheets also and one person described them as cardboard impregnated with bitumen.
My advice would be to avoid Onduline sheets.
