All roof decking may also be available in aluminum or stainless steel please call ahead for availability.
Sheathing should be a minimum of 19 32 inch thick.
That s considered to be the minimum.
In this case plywood should be a minimum of 3 8 inch thick.
Flexural strength can be assumed to be 33ksi unless a new single ply system is contemplated that requires a higher pull out strength.
This minimum will only work if the rafters are set 16 inches apart at most and if the roof doesn t have too much load.
The thickness of plywood used for roof decking depends on the roof slope the spacing of rafters and the weight of other material to be put over the decking as well as the design load the.
In that case a pullout test device can confirm adequacy.
Ans steel is a stocking distributor of steel roof decking in the sizes listed below.
Never attach roof sheathing with staples.
My cabin trusses will be 24 oc and i will use either 1 2 or 5 8 osb sheathing and a standing seam metal roof.
Roof will be fully vented.

Can someone direct me to blogs or q a titles that address roof sheathing thickness.
Post frames generally lack structural sheathing so the roof and wall panels must span between the supporting trusses or purlins.
Because 22 24 or 26 gauge sheeting is thicker and will therefore remain more structurally sound over a longer span than a 29 gauge the building needs fewer supports which saves your customers money.
A roof that lays practically flat will have a much heavier load than a steeper roof that allows rain snow and ice to roll right off.
However you may need to consider bolstering the plywood thickness for a roof that has a higher load.
Thickness of a steel roof deck can be determined at a roof hatch where the edge of the deck may be available for measurement with a micrometer.
Unlike with plywood siding the plywood sheet to be used for sheathing should be at least 3 8 inch thick.
Standard roof sheathing which consists of 4 by 8 sheets of plywood or oriented strand board or osb is 1 2 inch thick and attaches directly to the roof rafters or the roof trusses.
