How to Repair Rotting Garage Trusses
The garage roof may sag and become unsafe, if the garage trusses rot. You can repair them easily, at a low cost. If there are only small sections of trusses rotten, then it is easier to remove these sections, add new sections, reinforcing the trusses with new boards. Here are simple steps:
Step 1: Examine the Trusses
Check the old trusses. If these have only small portions with rot, you can repair using the boards. If the old trusses are too bad, theses may require placing new trusses, or complete restoration of roof.
Step 2: Cutting the Boards
Cut the new boards with width equal to the width of old trusses, and to lengths matching with the exposed parts of the beam.
Step 3: Fixing the Boards
Fix the boards to the old trusses, first at the eaves, and then move towards the peak. Make the roofline straight when fixing the boards. You can make use of a hydraulic jack to lift the trusses up.
Step 4: Reinforcing the Trusses
Fix cross members on the roofline, in the center between opposite trusses, for a strong reinforcement.
