Spray on Roofing: The Ultimate Guide To Spray Foam Pros And Cons

Are you looking for a commercial roofing material for your new business or home? Perhaps you’ve considered spray on roofing? Look no further than spray foam for your best option.

Spray Foam Roofing become a go-to for many businesses due to the fact that it’s sustainable, energy-efficient, and super easy to install and maintain.

Even the best things in life don’t come without their cons, however. It can be hard to find a contractor to do it and when you do there is only a small window of opportunity to install this roofing. The contractor could also overspray and get it on the cars below.

If you’re juggling the idea of this roof type in your head, check out this guide on spray foam roofing pros and cons to help you make your decision.

1. The Pros

Most people like to hear good news before they hear the bad, so we’re going to go over the pros of foam roofing before we go into the cons. The main thing you need to know is that it’s easy to install, energy-efficient, easy to maintain, and it’s waterproof!

Easy to install

The roof is installed by spraying liquid foam over the roof that already exists on your building. The foam expands and conforms to your roof. It doesn’t matter what size roof you have, what shape, or the type of material that it’s made of because the foam will work with it.

This easy installation coupled with not needing expensive materials and tools cut down the price of this roof type by a large margin.

Energy Efficient

Spray roofing is equipped with a barrier against moisture, thermal heat, and air. This means that it creates great insulation for your building so your heat and AC don’t have to work as hard to heat and cool it.

Not only will you be saving money on installation costs but you’ll see positive results on your power bill as well.

Maintenance is Easy

After your foam spray roof is installed it takes very little work on your part to keep it going strong for 50 years or more. If something does happen to it such as a tear all you have to do is have someone come out to fill the gap.

Literally, spray the gap closed and done. Unlike many other roof types, there is no need to rip anything up to make repairs.

Waterproof and Seamless

The main reasons why many roofs leak is because there isn’t a seamless application. Tricky rainwater can still work its way into your building through it and cause water damage.

The foam is installed as a liquid so it can sort of bleed into cracks that exist on your current roof to create a seamless, waterproof seal. The contractor can also level the foam down so water doesn’t pool on the roof and create water damage.

When water does gather on the roof it’s easy to clean and dry it. This amazing moisture control is what makes it resistant to mold and mildew that has the habit of growing on other roof types.


During the summer your roof will shrink and expand depending on what the temperature is like outside. Unlike many other roof types, the foam will move with the roof so there are no risks of cracks forming due to stress.

On top of being waterproof, foam roofs are also wind-resistant. You won’t have to worry about it getting damaged if you live in an area that’s prone to hurricane weather.

2. The Cons

Again, nothing is 100% perfect. Everything in life has some sort of con even if it seems like a perfect solution. The main things you need to worry about with spray foam roofs are small installation windows, overspray, maintenance, and repairs.

Small Installation Window

Spray roofs can only be applied in specific weather conditions. This makes for a small window of installation opportunity. For example, if it rained the night before you made installation plans you can forget it.
There can be no visual moisture on the roof when the spray is applied or it won’t stick. Same goes if things got icy the night before. It can be frustrating trying to find the perfect time to apply the roof depending on the weather conditions where your business is located.


When you’re working with a spray substance of any kind and you’re outside the wind has the tendency to carry it away. If this happens neighboring buildings and cars could be affected.

It won’t cause a health risk to anyone in the area but someone may be a little cross with you if your contractor gets bits of foam roof on their car.

Ensure you hire a professional like American Foam Experts to get the job done.
