Depending on the roof design and the roof rafter spacing.

Roof framing rafter spacing.

Ridge board shall be at least 1 inch 25 mm nominal thickness and not less in depth than the cut end of the rafter. L 720 l 600 l 480 l 360 l 240 l 180. The pitch and span of your roof will dictate how long of a rafter you ll need use maximum span calculator to help you find your rafter size. At all valleys and hips there shall be a valley or hip rafter not less than 2 inch 51 mm nominal thickness and not less in depth than the cut end of the rafter.

Common spacing for trusses on this type of building is often between 2 and 4 feet but trusses built with advanced designs may allow spacing as great as 8 or 12 feet. If your project had a rafter length of 8 or less a safe and strong method is to use 2x8 framed 16 on center. 3 stud construction standard utility. Visit the roof framing page for more information on cutting roof rafters and visit the roof pitch calculator for determining rafter lengths based on rise and run.

2x4 2x6 2x8 2x10 2x12. Anything beyond that you are looking at using 2x6s for most sheds. As a general rule roofs that have a high human occupancy rate should be framed with rafters every 16 structures such as sheds or barns can be frames with rafters every 24 again make sure to consult local codes.

Rafter tie or collar tie spacing intervals connection specifications building codes such as the icc s 2012 international building code section 2308 10 roof and ceiling framing typically specify that where rafter ties are used they are required at intervals ranging from 12 to 24 o c.

Double the hill and valley width since this is the amount that the panel will overlap the one next to it on each side. So if the pitch of your roof is 7 12 place one stair gauge on the vertical part of the framing square the tongue at the 7 inches 18 cm mark and place one stair gauge on the horizontal part of the framing square the body at the 12 inches 30 cm mark. So the space between rafters can be greater without reducing the maximum span. Subtract that number from the width of the panel and then divide by 2 to come up with the spacing for the rafters.
