If you have a 10 ft 3 0 m wide shed your roof will be 10 ft 3 0 m wide and 5 ft 1 5 m tall. The truss members will all be equal in both length and end angle measurements. Rip some osb into strips 12in wide and 8ft long. Make that pitch 12 7 a drop of 7 inches per foot from the connection to the wall.

Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape. See table 2 to get dimensions g and h. This barn comes with supports for a basic loft so all you are left to do is attach the loft floor. 4 truss members and 6 gusset plates.

The example i will use for showing you how to build your own gambrel shed trusses will be a 10 foot wide shed. You want to try and use angles that are as close to 45 as you can get for both ease of construction and good strength. Reverse that for the bottom angle. Depending on the size of the roof and the pitch of the roof these angles will change.

A gambrel or barn style roof is simply a gable roof with a change in slope partway up the roof. Cut off as little of each end as possible to make the angles.
