These prefabricated units reduce labor costs and make assembly both quick and easy. Rafter boards are fastened to the ridge board at the peak and the top plate where they join the wall. So to compare apples for apples let s leave that bearing support in there and let me design trusses over the same area. When a truss is installed on top of the walls it builds the roof slope and ceiling at the same time as one structural piece.

On the other hand members of frames are jointed rigidly at. Truss roofs are heavily reinforced so they are more durable. Just as there are many types of roofs with many roof parts there are many different types of roof trusses this extensive article explains through a series of custom truss diagrams the different truss configurations you can use for various roofs.

You will have to have a bearing wall or beam in the middle of this area to support the floor system and roof beam if you choose to stick frame the roof. They are made prior to installation by making triangular forms reinforced by several other planks of wood.

The truss is built within our manufacturing facility and then fitted directly on the job site. In truss joints are of pin joint type and the members are free to rotate about the pin.
