The Pros and Cons of Spray Polyurethane Foam for Commercial Building Roofs 

The Pros and Cons of Spray Polyurethane Foam for Commercial Building Roofs

If someone told you that you could start saving at least $200 a year, just by adding extra insulation to your home or business, would you do it?

Over 90% of single-family homes in the United States are not insulated correctly, leading to extra heating and cooling costs each month.

Proper home insulation keeps the heat from leaving buildings during the colder months of the year and helps to keep the heat out during the warmer months. Drafts wafting through due to inadequate insulation in the walls or attic can lower your comfort level.

Spray polyurethane foam is one of the quickest and easiest ways to address an insulation issue on your roof. Continue reading to find out why you should be using it in all your commercial buildings.

What Is Spray Polyurethane Foam?

Spray polyurethane foam, or SPF, has been used for over 50 years in commercial and residential buildings. It is durable in many climates, including hot and humid, making it a choice for areas where other forms of insulation may not work as well.

The foam seals walls, floors, ceiling cavities, and anywhere else that needs airflow prevention. This includes light fixtures and space where doors and windows connect to the wall.

One of the most useful functions of SPF is its ability to fill in cracks and gaps as well as keeping its shape. It also can act as an acoustic insulator by absorbing sounds.


While SPF can cost twice as much as other options such as fiberglass or cellulose, it often pays back the cost in energy savings. The time saved for installation also cuts down on labor.

The durability of using SPF with your roofing also may outweigh the price, as it can last upwards of 50 years if maintained.


The need to renew a resource can have both pros and cons. In the instance of spray polyurethane foam, the downside of needing to renew is small, as it may be twenty years before it needs updating. The initial application goes on thick, but re-applications are 1/3 to 1/2 as thick, leading to a lower cost.

A positive side of renewing your SPF is not needing to tear out and completely replace your insulation system. The re-application goes directly over the older foam, and the process is faster than your initial service.

Commercial roofing companies all over the country, like the one you can see here, offer inspection and re-application of your SPF.

Ease Of Use

SPF used in a commercial building can be applied in places other insulation material cannot. Since it only needs sprayed and not cut, such as when you use rolls or foam board, it can get into the hard-to-reach places.

A spray polyurethane foam system is the fastest way to complete your insulation project. Once you make sure that all the proper building materials are up to date, it takes only one step to spray the foam, then allow it to expand and dry.

SPF is not limited to building maintenance but is also used on motor vehicles, boats, trailers, containers, and any other building project where insulation is needed.
