How To Construct Roof Trusses

Begin by determining the measurements of the roof s slope.

How to construct roof trusses.

The overhang will depend on the size of the building or house and the pitch of the roof. Brace the trusses in place and check for plump prior to securing the frame. Even if you don t know how to build a truss any diyer with confidence can construct a simple roof truss for a shed. A gable roof is your typical two sided roof that meets at a point in the middle.

Then there is the top chord or rafters that are angled to make the roof pitch. The longer your shed is the more roof trusses you will have to make. The best way to assemble the trusses is to lay each rafter and bottom chord on the ground in the desired shape. 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.

This will be the rafters length. Again for the sake of simplicity we ll be building a truss for a gable roof. Toe nail them into the top plate to secure them and then make sure they are braced laterally using blocking or long purlins. Take two rafters and connect the peak at the plumbed corner you created.

The trusses you require may depend upon the shed s length. See gusset construction below. 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. Determine your shed roof pitch.

Trusses are commonly used to provide support for roofs bridges and other expansive structures. Use of manufactured roof trusses can dramatically cut labor costs when framing a gable roof compared to building rafters. There are three parts to the roof truss that you have to know. Do this by nailing the triangular gusses to the rafters.

The bottom chord which is the bottom of the framed truss. Now assembly of your roof trusses can finally begin. Attach the truss to the frame every 2 feet securing them with 3 inch deck screws. Install the roof trusses.

Finally there are the gussets that hold the framed truss together.
