Again for the sake of simplicity we ll be building a truss for a gable roof. Use of manufactured roof trusses can dramatically cut labor costs when framing a gable roof compared to building rafters. The bottom chord which is the bottom of the framed truss. The best way to assemble the trusses is to lay each rafter and bottom chord on the ground in the desired shape.

Even if you don t know how to build a truss any diyer with confidence can construct a simple roof truss for a shed. Then there is the top chord or rafters that are angled to make the roof pitch. Attach the truss to the frame every 2 feet securing them with 3 inch deck screws. Determine your shed roof pitch.

This will be the rafters length. The trusses you require may depend upon the shed s length. Take two rafters and connect the peak at the plumbed corner you created. Now assembly of your roof trusses can finally begin.

See gusset construction below. Trusses can be constructed with smaller sized lumber than rafters and often their cost is not significantly higher than normal rafters. Do this by nailing the triangular gusses to the rafters. Toe nail them into the top plate to secure them and then make sure they are braced laterally using blocking or long purlins.

Trusses are commonly used to provide support for roofs bridges and other expansive structures. To put together a simple wooden truss you ll fasten a number of pre cut beams into a chosen configuration inside a sturdy triangular frame which will help distribute the weight of the structure more evenly.
