Once the trusses are constructed lift them into place and set them onto the top plates of the exterior walls just as you would a beam or joist. Again for the sake of simplicity we ll be building a truss for a gable roof. The good thing about roof trusses is that they are simple to construct. A gable roof is your typical two sided roof that meets at a point in the middle.

Brace the trusses in place and check for plump prior to securing the frame. This will be the rafters length. The overhang will depend on the size of the building or house and the pitch of the roof. Attach the truss to the frame every 2 feet securing them with 3 inch deck screws.

Take two rafters and connect the peak at the plumbed corner you created. Then there is the top chord or rafters that are angled to make the roof pitch. Sheathing added on top of the trusses will provide final support to the roof trusses. Do this by nailing the triangular gusses to the rafters.

There are three parts to the roof truss that you have to know. Finally there are the gussets that hold the framed truss together. The longer your shed is the more roof trusses you will have to make. Trusses are commonly used to provide support for roofs bridges and other expansive structures.

The best way to assemble the trusses is to lay each rafter and bottom chord on the ground in the desired shape. Use of manufactured roof trusses can dramatically cut labor costs when framing a gable roof compared to building rafters. 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. Begin by determining the measurements of the roof s slope.

The trusses you require may depend upon the shed s length.
