How to Build Wooden Roof Trusses. You may refer to a truss as the rafter, but it's basically the skeleton of the roof, carrying the weight of the frame and supporting the walls of the building. Trusses are very important to preventing the walls from bending or flexing, more so important for buildings and homes with more than two stories. The building trusses are usually connected together with galvanized metal plates and connected together in a triangle shape. Most of the time, for smaller buildings and houses, trusses are made of timber because it's reliable and easy to work with, but it's not uncommon for trusses to be made of aluminum, steel, or another material.

Most of the time what material the trusses will be made of will depend on the budget of the project. If you're making your own truss, you need to make sure that you lay out everything before you get started. You want to make sure that you have all the right tools, materials, and equipment, and you need to make sure that you know what you're doing.

Purchase the highest quality timber that you can for the top chords (two pieces of timber that determine the roof's pitch) and the outer segments of the bottom cords (bottom pieces of the truss that form the bottom of the triangle) of the trusses. These will support the most weight, causing the most stress on the wood.

Check to make sure that the lumber is straight when you look from one end to the other. If the lumber is curved, you want to make sure to put the curve facing downward, so that when the weight is put on the truss, the curve is flattened out.
