What You'll Need

Building carport roof trusses is just the same as building roof trusses for any other outbuilding. The process does require attention to detail and a high degree of accuracy, but it is something that somebody with DIY skills should be able to manage. There are various tools and materials required, but you should be able to find everything you need at your local hardware store.

The trusses are one of the most important parts of any roof, as they support the weight of it. They are also used to stabilize walls in some larger buildings. However, since a carport is an open garage with corner pillars supporting the roof instead of walls, this is not an issue. Trusses themselves are triangular in shape and can be joined together using metal or wooden gussets.

Step 1-Taking Measurements

The first thing to do is take accurate measurements of all of the relevant dimensions. To begin with, you will need to measure the roof to make sure you will have adequately large trusses. You should then decide how steep the roof is going to be. If you are going to have one side of the roof steeper than the other, dimensions can get a little more complicated. Take all of the measurements and use your marker pen to put marks on the wood that you need to cut. Also, consider that there may be local building regulations which can make a difference to your construction.

Step 2-Cutting the Wood

To continue, you need to cut the timber to the size relevant to the span of the roof. The rafters will need to have plumb cuts in the ends so that they fit together with the bottom section. You will also need to cut the gussets. These are small triangular pieces of wood or metal which are placed over the connecting parts of the rafters. In total, you will need to have a lower chord spanning the width of the building, two braces and two upper chords as well as the plywood gussets.

Step 3-Putting it all Together

Assemble the trusses on the ground. This is not a complicated process if everything has been cut correctly. Everything should fit together and then you can start gluing things in place. Use strong wood glue to glue the rafters and chords together. However, glue by itself is not enough. You then need to apply the gussets onto the joints and then use hammer and nails to attach them firmly in place. You do not have to wait for the glue to dry before doing this.

Step 4-Putting it in Place

You will need at least one other person to help you put the trusses in place. The number of trusses that you need depends on the size of the carport roof. You will probably only need two or three, but if for any reason the building is longer than normal, you may need an extra one.
