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.
