On saturday i collected a couple of 18mm sheets of plywood.
How thick plywood for shed roof.
It is about 2 to 3 millimeters thick and is generally used indoors since it looks more decorative than thicker plywood boards.
For rafters spaced 20 or more inches apart 1 2 or 5 8 inch plywood is recommended.
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.
Use it indoors or outdoors but avoid using for framing permanent structures such as a shed or a home.
What thickness of plywood for shed roof.
For heavy load rated areas 3 4 inch thick plywood is recommended regardless of rafter spacing.
That s considered to be the minimum.
8d ring shank nails should be used instead.
It will support roof.
Keep in mind that the load of the roof still plays a role in the plywood thickness.
Most builders use 15 32.
Never attach roof sheathing with staples.
Since this is my first attempt at carpentry i was unaware of just how heavy and awkward it would be to manouver these sheets though i soon found out.
The typical thickness range for sheathing is 3 8 to 3 4 inch.
The most common rafter spacing is 24 inches and 5 8 inch plywood is recommended for that.
Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame.
The work is in building it collecting the material etc so i take the view that the extra cost is small compared to the work effort.
Unlike with plywood siding the plywood sheet to be used for sheathing should be at least 3 8 inch thick.
Due to requiring extra tools for cutting the sheets to size the roofing job for the shed hasn t been completed.
Thicknesses of 1 2 to 5 8 inch are common with rafters spaced at 24 centers.
If you want the shed to be waterproof its roof must be constructed just like any other roof a plywood decking covered with shingles or with composite or metal roofing.

When this is the case experts recommend a 5 8 inch thick sheet.
5 ply is a versatile type of plywood that is about 4 millimeters thick.
Plywood thicknesses for roofs start at 3 8 in areas with light load requirements on rafters at 16 centers.
