Roof sheet fixing.
Remove roofing and turn each sheet over.
Stagger the sheathing in a brick pattern for extra strength.
The first raw of fixings at eave is located at 2 5 cm from the edge of the roof support osb or purlin.
Start laying sheets over the gutter with 6 cm overhang maximum.
Whether it s a corrugated roof made from bitumen or a flat sheet roof made from plastic our fixings are compatible with many types of roof sheet.
You will have to paint the roof but is cheaper than buying new roofing.
The general advice for fixing is 4 5 screws across the sheets purlin we advise using 1 screw on the overlap of the next sheet.
We recommend the use of our self drilling tek screws with 5 16 hexagon heads and 19mm sealing washers for fixing your roof.
After cleaning the debris and reframing the roof lay down a base sheathing.
Lay sheets in the opposite direction to the prevailing winds.
As with all of the fixing screws provided you can use a colour cap to hide the stainless steel head.
What was previously a valley in the corrugations will now be a ridge and the nail hole will be in the correct place.
If fixing screws are left in the valleys your roof will leak in hundreds of places.
You ll will find everything from nail fixings to glazing bars jointing strips and edging strips.
Up signs indicate the direction of the ridge to lay the sheets correctly.
Eight foot 1 2 inch thick plywood is standard sheathing material.
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.
These should be long enough to get a secure fixing into your purlins.
