If wondering why you should build roof trusses, you should ask an expert about the proper support of the roof and its weight. Trusses are used to stabilize and support the walls, especially in large buildings that have more than 1 or 2 stories. Roof trusses are usually triangular and can be easily installed. Another advantage is that they are quite practical and they can be joined with numerous different materials. Installing roof trusses for your garage roof is not hard, especially if you follow certain tips and hints.

Step 1 – Cutting the Timbers

The first thing you need to do is cut the timber panels to the size of the garage roof. Measure the span of the roof or check with the building plan and project. Before buying the timber panels, you should also consider the weight they will be supporting, because that will help you determine their thickness. In most cases, you will need to buy 2x8 inches timber panels and then cut them to size if needed.

Step 2 – Secure the Timber Panels Together

Use the connector plates to secure the timber panels, creating a triangle – since roof trusses are supposed to be triangular in shape. Use the screws to secure the panels together in that shape.

Step 3 – Add the Brace

Use a brace to dissect the triangle center. If you need to have sturdy trusses that will support a load, you should use additional supports from the bottom and up to the top of the trusses. This way the roof trusses will be able to bear much bigger loads easily.

Step 4 – Secure the Trusses

The next thing you need to do is secure the roof trusses to the frame. Make sure that you leave the proper overhang. If you are not sure what is the appropriate overhang, you should check the size of the garage roof and the roof pitch. You can also consult with an architect or mechanic who can advise you on the measurements.

Step 5 – Attaching the Trusses

Use the deck screws to attach the trusses to the roof frame. Most professionals would suggest you to brace the roof trusses, checking for plump, since the most reliable – and final – support will be the sheathing.

Extra Tips

  • Never start with any constructing project without checking the building and local code. You need to ensure safety before building anything new to your house and garage. The building project and the code will also give you an idea on the size of the timber you should buy.
  • In some cases, the building codes do not allow you to complete any building projects without the participation of a professional or a mechanic. Roof trusses can be critical to the stability and integrity of the garage and any construction. Roof trusses will hold the majority of the roof weight and will ensure the stability of your garage.
