A well-insulated home is a benefit to your property and your family. Spray foam insulation creates an environment that is warm and comfortable, but how can you tell when an area is worth insulating and when it isn’t?

Knowing where to add insulation to your home can be difficult, after all, insulation is a big investment and some areas of a property will benefit more from insulation than others. 

If you’ve recently installed an extension with a flat roof or have areas in your home with a flat roof that have never been insulated, then you may be wondering whether bothering to insulate those areas is going to make a difference. 

To help you decide whether flat roof insulation spray foam is the best option for your home or not, we’ve put together a list of the top pros and cons. Read on to see what spray foam insulation on your flat roof has to offer and what it doesn’t…

Spray foam on the underside of a flat roof will also reduce the number of hot and cold spots, leading to a much more regulated temperature overall

The Pros of Flat Roof Spray Foam Insulation 

As warm air rises, insulating the roof of your home to prevent the heat escaping is always going to offer a great range of positives. Here are five of the biggest pros of flat roof spray foam insulation:

Energy Efficient 

Spray foam roof insulation can help to increase your energy efficiency rating, reduce the cost of your energy bills, and help the environment by lowering your property’s energy use. 

As more heat will stay inside your home for longer, you won’t need to turn your heating up as high or turn it on for as long. 

Temperature Control

Insulation keeps a home warmer in the winter and cooler in the summer, improving the comfort of your property all year. 

Spray foam on the underside of a flat roof will also reduce the number of hot and cold spots, leading to a much more regulated temperature overall.

A bit of peace and quiet is more than just pleasant, it’s actually a benefit to your health. Spray foam insulation on your flat roof will dampen any exterior sound, so your rooms will be quieter and more peaceful than they were before insulation was installed

Water Protection

Roof leaks and condensation can cause serious damage to the structure of a property and the interior of a home, but with spray foam insulation, the risk of water damage is reduced. 

Both closed and open cell spray foam can help with water protection, although closed cell goes one step further and offers water deflection properties. 

Structural Reinforcement

As well deflecting water, closed cell spray foam can also help to reinforce the structure of your home. The strong insulation material is impact-resistant and forms a very strong bond with the materials that it’s applied to.  

Sound Dampening

A bit of peace and quiet is more than just pleasant, it’s actually a benefit to your health. Spray foam insulation on your flat roof will dampen any exterior sound, so your rooms will be quieter and more peaceful than they were before insulation was installed.

Professional installation is a must with spray foam insulation as the product needs to be handled carefully during installation and installed correctly in order for it to be as effective as possible

The Cons of Flat Roof Spray Foam Insulation 

When insulating your flat roof with spray foam insulation, there are a number of negatives that it’s essential to consider. Here are three of the main cons of flat roof spray foam insulation:

Cost

Spray foam is a premium insulation material, which means that the cost can be more than some of the alternatives on the market. 

Whilst this can be a con initially, the effectiveness of spray foam as a leading insulation material certainly provides a great reason for the additional cost. 

Professional Installation

Professional installation is a must with spray foam insulation as the product needs to be handled carefully during installation and installed correctly in order for it to be as effective as possible. 

With strict safety procedures needing to be followed, installing spray foam as a DIY job can be risky

Best Suited to Creating a Cold Roof

Spray foam insulation for a flat roof is much better suited to creating a cold roof, not a hot roof. 

The difference here is that a cold roof has insulation inside, so the roof remains cold and a hot roof has insulation on the outside, so the roof is warmer.
