The Benefits of Insulating Your Garage Ceiling

Insulation plays an important role in cooling or heating your garage. While it is a common practice to insulate your garage walls and doors alone, neglecting the ceiling can reduce the effectiveness of your cooling or heating systems.

Is there a living space right above your garage? Do you have a roof that traps heat? If so, it may be time to consider adding spray foam insulation to your garage ceiling.

Insulating your garage ceiling provides many benefits, such as:

  • •  Keeping the heat out
  • •  Additional sound barrier
  • •  Increases the value of your home
  • •  Improves the lifespan of your roof

You might ask yourself, is insulating my garage ceiling ideal for me? Let’s take a look at some benefits of insulating your garage ceiling.


Insulation helps to keep the heat out


Garages are often the largest non-insulated space in most houses. As it is important to insulate your garage door, it is crucial to fix your garage ceiling and keep it in check. If you have living space above your garage, the heat will channel through the garage ceiling into the floor above. This can easily increase the whole temperature by several degrees in the summer. This also contributes to a higher air conditioning bill, particularly if you have a portable air conditioner—and no one wants that! Closed-cell spray foam has an R-value of up to 6, which helps keep the heat out.


Insulation serves as a good sound barrier


Whether you are using your garage for parking cars, workout, or making music, insulating your ceiling helps reduce noise. A household win for everyone!


Insulation can increase the value of your home


Having your home well-insulated can be the difference between a potential buyer purchasing your home or your neighbor’s home. It’s one less step for a new homeowner to have to do and helps maintain the property while increasing its value—something buyers look for in a property!


Insulation improves the life of the roof and floor above it


Serious temperature changes can shrink or expand the wood and drywall in your house. This can cause your home to have door gaps in the winter, making it nearly impossible to open doors in the summer. Insulation can help reduce those noticeable seasonal changes throughout your home.


Having looked at the benefits of insulating your garage ceiling, let’s walk through the spray foam insulation process.

Steps to Insulate Your Garage Ceiling


While there are quite a few DIY videos showing how you should insulate your garage ceiling, we suggest you call a professional to install your garage spray foam insulation. This will give it a perfect finish. Let’s break down how we tackle garage ceiling insulation:

Remove everything from inside the garage

The first thing we’ll need to do is to remove everything from your garage to avoid getting it on your valuables because insulation can get messy sometimes.

Find all electrical boxes

We must get electrical boxes that can heat up without a fire hazard. There should be enough space around all wiring as well as some electrical parts.

Install insulation against walls

A common DIY mistake is using too much spray foam, which results in insulation gaps. It is important not to allow space or gaps between insulations. We apply the right amount of spray foam for each space.

Replace ceiling panels

This is the last step of insulating a garage ceiling. Adding insulation to a garage ceiling is an important task in every home.
