If you are considering putting up a new roof or simply need to have major repairs done on your existing roof, you may want to think of DIY  roof truss. Roof trusses are one of the popular roofing alternatives in the market. Unlike traditional roof frames, roof trusses are more economical to construct. Engineered roof trusses are designed by computer software which take into account the amount of material, span and pitch of the truss. Engineered roof trusses are made from high quality materials which are isolated from air and other contaminants. Moreover, one saves on labor as the time involved in installing the truss structure is much less than installing traditional frames. Roof trusses also have several advantages over the other options such as durability and economy.

Generally, roof trusses are pre-fabricated structures which are manufactured in closed-off factory environments. However, one can build their own truss system. However, to do so, you will need adequate knowledge of what goes into building truss structures. Moreover, you will need to get the proper permits to get the job done. Completed roof trusses will also need the right certification as will be explained further on.

When building DIY roof truss. start by choosing the appropriate design for the structure you have in mind. You can get truss designs from truss manufacturers. One can get the standard truss design or have one custom built if necessary. When choosing custom designs, you may need an understanding of what goes into the design and engineering of trusses. You may choose to add a few structural enhancements to the design. Before adding any structural enhancements, you should check with your local permit office.

When building some roof trusses, you may need to consider the engineering calculations such as the required wind load calculations. Most roof truss manufacturers will provide this for your design when ordering the design. Your Local Building Authority will need this proof as well as the appropriate certification that the structure you are building is structurally sound. Unless you have a very small building and expect very little loads imposed on its roof, you will need to provide the necessary engineering calculations.

Making structural roof trusses from your workshop at home may be somewhat difficult. It requires one to have the necessary joinery skills as well as the appropriate tools to handle heavy lumbers. Moreover, you will also need a large enough space to manipulate them. You will also need the skills to be able to work these timbers to form tight joints. However, conventionally nailed trusses are much easier to work with.

The typical DIY roof truss is comprised of four parts. These are the upper cords, popularly referred to as rafters. These form the peak of the truss system. The lower cords form the horizontal bottom which ties the upper cords together. Another important part is the vertical brace which runs from the top edge of the lower cord to the underside of the peak. This part is also referred to as the king post. Gussets i.e. plywood plates are normally used to attach the joints.

The basic tools required for DIY roof truss include a tape measure, disc sander, belt sander, combination saw, 16” Beam saw as well as ratchet straps. You may also need a reciprocating saw, chainsaw mortiser as well as a Hole Hog.

The first step to building DIY roof trusses is to assemble all the trusses together. To do this, you will need a large, flat space to lie the timbers flat on the ground. The ratchet straps will then be used to tighten the timbers together. Care should be taken to ensure that the tightening is done according to the labeling as well as the manufacturer’s building instructions. If the shoulder is too long, gaps may appear. As such, you may need to use culprits on the back of the joints to prevent this.

Roof trusses are normally placed 2” off center in most residential and commercial buildings that have gable roofs. As the third step, you will need to mark two inches off the center on the sidings for this purpose.

The trusses will then need to be raised upside down and then turned over with the long brace placed in position. The truss is then secured to the top plate by toe-nailing and staked securely in place.

The next step is securing the main trusses to the vertical bracing of the building’s back wall. The horizontal brace is then used to fasten the trusses together. Afterwards, you will need to install a ridge beam to connect the smaller trusses to the main roof. To attach the ridge beam to the main roof, you will need to use the rafters.

When making DIY roof trusses. it is necessary to cut the timbers to the appropriate angles as well as nail and screw them together. When cutting the timbers to the appropriate angles, you will need to use the angle finder. With an arm on each side of the peak of the truss triangle, you need to read the angle from the center of the finder and divide it by 2. The angle found through this process is the angle required for the cord end cuts.

While doing so, it is important to ensure that, in all the appropriate areas, they are all identical. Failure to do so could leave you with a very expensive mistake. Common mistakes include a roof that may not fit the building or one which has wavy lines for the roof plane.

The LABC certification is required for most building specifications. Garages, in some cases may not need such LABC approval. For instance, if your garage requires a truss system with a low pitch and a narrow span, then you may not need the approval.

However, if you intend to build attic trusses or any other that has storage area in the roof, then you will certainly need the LABC approval. Simple buildings such as sun rooms may only need simple straight forward trusses as the solution.
