How many nails should I use per ONDULINE sheet?

Approximately 20 fasteners, nails or screws, must be fixed per sheet depending on the roof pitch. It is important to use Onduline fasteners as they are specifically designed, developed and manufactured to suit the roofing application requirements with ONDULINE sheets. Please consult Onduline Fixing Guide. Onduline Warranty is applicable when ONDULINE has been installed in full respect of Onduline's installation instructions and if the system is installed with Onduline accessories and fasteners.
