Spray Foam Roofing Pros and Cons: Is It Worth It?

There are many roofing coats you can get for your commercial building today, but not all of them will provide your existing roof with the resistance it needs against water or other agents.

One of the most popular materials out there is spray polyurethane foam roofing, commonly known as SPF roofing. It’s known for having excellent insulation and waterproofing qualities, making it great for those who want a tight and healthy roofing system for many years to come.

Spray foam roofing comes with several benefits in the roofing industry. However, it also has some disadvantages you may want to consider before installing it on your property. In this blog, we’ll cover everything about the foam roof system and how it can benefit you.

What Is Spray Foam Roofing (Spray Polyurethane Foam)?

Spray Foam Roofing

Also called “SPF Roofing,” spray foam roofing is a material composed of three parts:

  • Spray polyurethane foam
  • Ceramic granules
  • Silicone coating (Top coat and base coat)

How Is It Achieved?

The SPF roofing system is achieved by combining and heating two chemicals (isocyanate and polyol). Once they’re heated, the foam will increase in size by at least 30x, allowing the contractors to customize the foam to all roofing systems. These are excellent choices for those who have flat roofs.

Spray Foam Roofing Pros and Cons

What Are the Advantages of Spray Foam Roofing?

A spray foam roof can provide several benefits to your existing roof. The primary benefit is that it could potentially help you save on energy costs. According to research, spray foam roofs have the highest R-value, which is the factor used to measure the ability of an insulating material to resist heat.

Your SPF roof can provide excellent thermal, moisture, and air barriers, achieving better insulation. Moreover, the silicone layer installed on top of the spray foam roof will help with UV rays.

Another excellent thing about this roofing material is that it’s considerably easy to maintain by a professional. If you take care of your spray foam roofs, you can expect them to last over 50 years! Overall, when properly maintained, this protective coating has waterproofing qualities, so you don’t have to worry about leaks.

Finally, foam roofing doesn’t create as much waste as others since it doesn’t produce as many volatile organic compounds as other options.

What Are the Disadvantages of Spray Foam Roofing?

Keep in mind the following factors if you plan on installing foam roofing on your flat roof:

First, foam roofing provides only a small window for installation; this limited installation window means that it can only be installed during particular weather conditions, so you must hire a professional that knows the perfect time to install this on your entire roof.

On the other hand, if you don’t work with reputable contractors, you risk overspraying, which can damage surrounding cars or other surfaces. Finally, whether you’re having problems with your roof or not, you must inspect and do regular maintenance to it, specifically twice a year.

All of these problems can be solved by hiring a reputable contractor.
