How thick should the roof deck be?
When installing Onduline roof sheets on a roof pitch less than 10 degrees, it is important to ensure you use a full deck. The minimum deck thickness should be 18mm.
It is preferable to use an 18mm deck, as this ensures that the fixings do not penetrate the underside of the roof area. If your board is thinner than this, then you will need to add additional battens. It is better to put the battens on the inside of the roof area, as this means the roof sheet is still fully supported by the roof deck.
