Roof sheet fixing.

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.

After cleaning the debris and reframing the roof lay down a base sheathing.

Eight foot 1 2 inch thick plywood is standard sheathing material. As with all of the fixing screws provided you can use a colour cap to hide the stainless steel head.
