ONDULINE Sheets Installation

Start fixing sheets at the opposite to prevailing winds end of the roof.
Begin every second raw with a sheet cut in half vertically.
Fix 20 nails or screws per sheet to have a long lasting and guaranteed roof. Nail or screw every corrugation on eaves, overlaps and ridges.
