How to Strengthen Garage Trusses

What You'll Need
3-inch galvanized wood screws
1/4 -inch plywood
Tape measure
Power screwdriver
Wood glue

Garage trusses are not as sturdy as trusses found in homes. Mass amounts of snow as well as years of being exposed to the cold and heat can cause garage trusses to weaken. The wood will expand and contract with the weather. You can strengthen garage trusses easily and this article will show you how.

Step 1 – Measuring

Examine the garage trusses you wish to strengthen. Measure the length and width of the area. If there is damage; add a foot to the measurement. This extra length spans beyond the damage to stabilize and strengthen the truss as the extra wood is installed horizontally along the truss.

Step 2 – Cutting

Transfer the measurements to the sheet of plywood. You will want to make two pieces for each of the garage trusses you want to strengthen.

Step 3 – Strengthen the Garage Trusses

Apply wood glue to each piece of plywood you cut and then sandwich them on the garage trusses. Clamp them in place. If any of the garage trusses are cracked then center the plywood over the crack. Begin installing the screws every foot along the perimeter and on the ends. Avoid putting screws near cracks.
