Osb for shed roof thickness.

I m halfway though sheeting the roof of my shipping container shop and already need to redo some of it. Currently we space rafters 16 oc and use 7 16 osb with h clips. This manufactured wood product is composed of small wood chips that are arranged in layers and glued together. Watch this now to learn how to avoid this same pr.

Thicknesses range from 5 16 to 3 4 inch and the proper one to use. Osb roof decking thickness 7 16 1 2 or 5 8. Typical types of wood used for roof sheathing are oriented strand board known as osb and plywood the most popular being osb. The osb thickness will be based on the rafter spacing.

Good enough for houses good enough for a shed. For the curious 7 16 osb has a span rating of 24 16 and with supports every 24 inches is good for a roof live load of 40 psf pounds per square foot with a 10 psf dead load.

For heavier loads a 40 20 rated panel 19 32 or 5 8 will support a 130 psf live load and 48 24 rated panels 23 32 or are good to175 psf. Sheets of 7 16 inch thick with no edge support can be used in an area where the snow load is 30 pounds per square foot. 7 16 will be fine for 16 on center and 5 8 for 24 on center rafters.

Osb is sold in 4 by 8 foot panels and the standard panel thickness for osb sheathing. The thickness required by josh s circumstances are good for roof snow loads of up to 70 psf again spanning 24. Osb comes in 4 by 8 foot sheets as does plywood but the manufacturing process allows the production of longer and wider ones. I m contemplating upgrading to 1 2 or even 5 8 osb though to reduce roof sag hopefully to nil.
