About 35% of electricity in the U.S. is consumed by commercial buildings. If you want to reduce your building\’s energy efficiency and experience some other important benefits, you might want to install spray polyurethane foam (SPF) roofing.

While there are many types of roofing that you can install on a commercial building, you should consider SPF roofing if you\’re making an installation or replacement. This foam roofing is a unique type of roofing that is unlike other materials.

If you want to learn more about this option, keep reading. In this guide, we\’ll explain the pros and cons of SPF for commercial roofing.

What Is Spray Polyurethane Foam Roofing?

Spray polyurethane foam (SPF) roofing is a type of roofing that is often used for commercial roofs. SPF roofing has been used since the beginning of the 1960s and continues to be a good choice for commercial buildings for a variety of different reasons.

With SPF roofing, this foam material will be added to an existing roof to create a solid layer. This makes SPF roofing a great option to consider when updating an existing roof.

The installation of SPF roofing is quick and easy. You\’ll be able to update your current roof with very little effort while adding extra durability to it.

Making the choice to install SPF roofing isn\’t one to take lightly, however. It\’s important to consider both the advantages and disadvantages of this type of roofing before choosing to install it.

Benefits of SPF Roofing

There are a variety of advantages to spray polyurethane foam roofing compared to other options. Here are some of the main advantages that you should keep in mind.

Easy to Install

Installing SPF Roofing is an easy process that won\’t interrupt business operations at all.

During the process, a liquid coating will be applied to your building\’s roof with the help of a hose. This coating expands into foam and can work well for all roofs and roof shapes.

Professionals installing SPF roofing can work very quickly, getting the coating installed efficiently.

Energy Efficient

One of the greatest advantages of SPF roofing is that it serves as a great way to improve energy efficiency in your building. It offers great insulation and can help your commercial building maintain the perfect indoor air temperature.

SPF roofing has excellent thermal resistance, so it can help to improve your electricity bills by reducing energy transfer.

Easy to Maintain

SPF roofing is also easy to maintain, and if you do it right, your roof can last for 50 years or more.

It\’s best to inspect SPF roofs every other year to ensure that there isn\’t any damage and that the silicone layer hasn\’t worn down too much. To maintain the roof, it may be necessary to add more silicone coating as time goes by.

Great Durability and Resistance

SPF roofs offer great durability and provide significant UV protection and wind resistance.

This makes SPF roofs a great choice for buildings that are in high-wind areas. SPF roofing has a wind-up lift rating of about 160 pounds per square inch.

The roof\’s UV resistance is also impressive and can help to further improve its durability.

Environmentally Friendly

A major advantage of spray foam roofs is that they are environmentally friendly and sustainable.

When reinstalling a roof, spray foam insulation can easily be added on top without needing to dispose of the original roof. This helps to reduce waste and will be better for the environment overall.


Many building owners opt for SPF roofs because they\’re seamless and leak-resistant. SPF roofs have closed-cell properties which help to prevent leaks and eliminate vulnerabilities.

When SPF is applied to a roof it is done so as a liquid, so it will fully fill cracks and gaps. Compared to other low-slope roofing systems, SPF roofing has a distinct advantage and will do much better at preventing leaks.

Drawbacks to SPF Roofing

While there are a lot of positives to installing SPF roofing, there are drawbacks as well. Here are some of the main negatives of SPF roofing that you should consider.

Specific Installation Requirements

When installing SPF roofing, you\’ll need to do it in a very specific time frame.

The temperature needs to be more than about 55 degrees Fahrenheit in order to install SPF roofing successfully. Weather conditions will also need to be acceptable. There can\’t be rain, ice, frost, or any moisture during installation.

Because of these requirements, finding the right time to install the roofing can be difficult, especially in states such as Wisconsin.

Overspray Potential

Overspray can also cause issues when installing SPF roofing as well. If there\’s a lot of wind on the day of installation, the spray foam could be carried elsewhere, such as to the surrounding property.

It\’s important to take complete care when installing SPF roofing so that the risk will be minimal. Make sure you understand the benefits of hiring a professional roofer. Consider hiring professionals to work on your roof when installing SPF roofing to avoid overspray issues.

Deciding Whether You Should Install SPF Roofing

If you need to update or install a roof in your commercial building, consider choosing SPF roofing.

SPF roofing is an energy-efficient roofing option that is both easy to install and easy to maintain. It\’s also very leak-resistant, so this makes it a great choice if you want to keep your commercial building as dry as possible.
