Can You Raise Ceiling in Garage? Yes, Here’s How

Many people do mistakes when increasing garage ceiling height. You can easily raise the ceiling from 6′ to 8′ or 8′ to 10′ feet without removing the roof.

You’ll have to work with trusses to raise the garage ceiling. You can’t modify the trusses because they are built structural elements. But you can change the trusses to bigger in size so that you can increase the ceilings in the garage.

Working with trusses is not easy at all. It requires a lot of engineering work. It can be dangerous sometimes if you don’t do it properly.

So, you must be careful and safe with every calculation and step. It won’t be much difficult if you follow the right steps and have the right tools for it.

How to Raise the Ceiling in Garage

You need some tools to complete all the steps.

  • Woodcutting machine
  • Safety Glasses
  • Gloves
  • Headphones (for ear safety)
  • AutoCAD for calculations (you can do manually too)
  • Measuring Tape

Step 1. Find the space above

In the first step, you will have to calculate how much space you have left above the lower chord so that you can know how much higher you can increase the ceiling.

You will have to do calculations right because after that you will remove lower chords and will place new beefier scissors trusses. If you do any mistake in calculations, then the whole roof can collapse.

Take out your measuring tape and write down all the calculations which you will get from above the lower chord. And, from wall-to-wall distance to place new beefier scissors trusses to raise the height.

After that, you will have to find out the strength of those tope trusses.

Step 2. Finding out the strength of top chord trusses

This is the most important step because your whole roof depends on it. So, you can’t do any mistake about it. Now in this step, you will have to find out the strength of top chord trusses.

With the maximum snow and wind load in the area and find out what are the safety factors of these trusses. You can all do these easily by designing new trusses models in CAD.

Step 3. Design a new trusses

Now after taking out the strength of old trusses. First design a model for new beefier scissor trusses. You can easily design new trusses with the help of CAD.

CAD will give you a more accurate design and size of new trusses to make sure the lift fits perfectly. You can also design mock cars in CAD. So that you can have a better look that what it will look like after completion.

Calculate every single dimension and every single angle in the CAD. And the strength of every wood to for taking out a safety factor.

Step 4. Taking out a safety factor

This step is very important because safety is always first. The good thing about the model is that we make everything ready even before starting the process. And the model helps a lot during every process.

So, after all the calculations and making the model, now calculate the safety factor in the model. Make sure that our safety factor is just as good as it was in the original design.

You can easily calculate the safety factor in CAD too. Now after calculating the safety factors, you can now start to make new trusses for the top chord.

Step 5. Now make new beefier scissor trusses

Now in this step, take a woodcutting machine and start making trusses. Cut the wood into beefier scissor trusses which you place at the top chord trusses.

But remember that, you will have to cut the trusses into the exact dimensions and sizes which you calculated in the model. You can’t do mistakes on it otherwise it won’t fit in. And then fix it on the top chord.

Step 6. Fix the new trusses

Fixing garage trusses

Now we are almost on the last few steps. In this step, you will have to fix the new beefier scissors trusses into the top chord. You will fix them in a cross that’s why it is called scissors trusses.

After fixing the new trusses, apply some load to them. So that you can make sure that the new trusses are strong enough to hold the roof. After fixing the new trusses, now you will have to remove the lower trusses.

Step 7. Removing the lower chord

In this step, you will remove the lower chord (lower trusses). Because new beefier scissors trusses have been fixed on the place of it.

So, we don’t need them now. After removing them you will easily raise the ceiling from 8’ to 10’ or even more space in your garage height.

There are even some more methods, some of them like raising a garage roof by jacking up. In this method, a hydraulic lift is used for raising the garage ceiling joist but for that, your garage should be well structured and strong.

There is another method in which you can raise the actual garage. You can extend the walls by raising the garage ceiling joist adding more footers to the floor.

These all methods are much time consuming and too much expensive so you should not go for these types of methods at all. Of course, you can raise the garage ceiling by placing new trusses at the top chord point by replacing old trusses.
