Measure the opening of the section of roof to be shingled cut the plywood to size and nail to roof rafters. Up signs indicate the direction of the ridge to lay the sheets correctly. After cleaning the debris and reframing the roof lay down a base sheathing. What was previously a valley in the corrugations will now be a ridge and the nail hole will be in the correct place.

These should be long enough to get a secure fixing into your purlins. Stagger the sheathing in a brick pattern for extra strength. The main fixings are used to transfer all the loads acting on the cladding back to the supporting structure and to form a watertight seal. The first raw of fixings at eave is located at 2 5 cm from the edge of the roof support osb or purlin.
