Spray Foam Roofing: Exploring The Pros And Cons

While spray foam roofing is still relatively new to the commercial roofing industry, this roofing option has already begun to rise in popularity because spray foam coatings offer a wide variety of benefits that are ideal for most commercial roofing applications. However, like all roofing materials, spray foam also comes with some disadvantages that you will need to consider. Below you will learn more about both these pros and cons so that you can make a truly informed decision regarding whether or not spray foam roofing is right for you.

The Pros

  • Energy Efficient - After spray foam is applied to your roof's surface, this foam will continue to expand in order to fill in every air gap on your roof. This ability to completely eliminate air leaks allows spray foam roofs to offer superior insulation and will ultimately result in your building becoming more energy efficient.
  • Watertight - As spray foam cures and hardens, it will form a watertight seal around your entire roof. As a result, spray foam roofs are able to offer superior leak protection.
  • Affordable - While spray foam still costs slightly more than traditional asphalt materials, this roofing option is incredibly affordable when compared to other high end roofing options, such as slate or rubber. This can be a very important feature to keep in mind when looking for a durable roofing option that won't blow your budget.
  • Low Maintenance - Thanks to their virtually indestructible surface, spray foam roofs will require no special maintenance over the years.

The Cons

  • Complex Installation - Applying a foam coating to your roof will require precision and a thorough understanding of how the foam will react to different weather conditions. This complex installation cannot be performed by all roofing contractors.
  • Possibility Of Overspray - During the installation of your spray foam roof, the wind can carry overspray off of the rooftop and onto the surrounding surfaces. This can potentially damage any cars that are parked nearby. Therefore, the entire area surrounding the building will need to be evacuated before installing this type of roofing material.
  • Cannot Be Installed In Cold Temperatures - As the temperature nears the freezing mark, spray foam will lose its ability to cure properly. Excess water on the roof's surface can also interfere with the foam's ability to cure. Consequently, this roofing material should never be installed during cold or wet weather.

The Bottom Line

While spray foam roofing will prove extremely beneficial for many commercial property owners, this roofing option may not be right for everyone. For instance, business owners who require a replacement roof in the cold of winter may find that a spray foam roof is simply out of the question. In order to learn more about the pros and cons associated with this roofing option, or to schedule the installation of your new foam roof coating, be sure to contact a reputable contractor who is experienced in working with foam roof coatings.
