The roof truss system is one of the most crucial parts to home construction. Aside from personal preference the style of the truss must be designed to properly support the roof of the home. The very first step for building roof trusses is to prepare a design layout that can be sketched by a professional architect or can also be done by using a software that is specifically meant to design a roof truss. If you re looking for a complete guide for roof trusses then you ve come to the right place.

The same thing is true for the bridge of the truss. These steel joints are needed to support the overall truss. Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. The number of pieces is determined by the number of trusses to hang.

These 2 by 4s will be placed between the trusses at the wall plates where the trusses attach to the top of the walls. You can use the links below to navigate throughout the guide.

As well running an attic air duct system can be very difficult if the roof trusses were not designed for that application. Then flip it over and press it firmly into place over a joint between two truss beams.

The last space will be slightly under 24 inches. Cut several 2 by 4s to 22 5 inches long. Make another line 1 inches in from that. The second step in building a roof truss is to prepare the materials needed.
