Step By Step Procedure

Step 1

Firstly, check whether there is any damage to your beams. Check it thoroughly for any types of termite infestation. If you don’t know what a termite infestation looks like, do not fret.

See if there’s any mold forming in the beams. Again, see whether the wood seems swollen or whether the wood is buckling. While you are at this process, check for water damage in the woods also.

If your woods are infested by termite, you are better off replacing the whole beams. Termite infestation gets worse with each passing moment.

However, if the beams are not termite-infested, you can easily repair them.

Step 2

After you’ve checked the condition of your beams, you need to buy some timbers. Take the measurements of your trusses. You will need the same number of beams as the trusses of your garage roof.

Double-check to be sure about the measurements. After that, get 2×6-inch lumbers with lengths matching the beams.

After you have purchased the beams, you should start with the construction process.

You have to start by laying out woods under all the beams individually. Then you should lift up on the eaves side.

After you’ve done so, you have to drive a 6-inch nail below the beam. The nails will hold the beam temporarily. You should follow the exact procedure on the other end of the beam. 

You can take some help here. Get a friend or family member to hold on to one side of a beam. After that, work on the other side.

Attach the beam to the sagging beam. For that, you will need 4-inch screws. Drill them in the beam.

You should follow this for each and every beam of your garage. As the beams are being fixed, now the roof should be lifted gradually.

Step 4

In this step, you should buy a number of timbers. Make sure that their length is equal to the distance between your garage floor to your beams.

Secure these timbers under the beams. Try to put at least four of these timbers. Doing this step will ensure the longevity of your garage roof. 

Tips To Follow

  • Make sure whether your beams are termite-infested or not. If you are not sure about it, seek professional help.
