How Can A Spray Foam Roof Cut Your Energy Bills?

When it comes to choosing a roofing system for your commercial building there are lots of factors to consider, including roofing materials, projected lifespan, and initial installation cost. However, one of the biggest considerations should be how your new roof will impact your energy costs over time.

According to, heating, ventilation, and air conditioning account for 35% of a building’s total energy use. That means an energy-efficient roof could spell significant savings in both the short and long-term.

One commercial roofing system that has proven to be particularly energy-efficient is spray foam roofing (SPF). Let’s take a look at the factors that make SPF roofing an excellent choice for lowering your building’s energy bills.

Superior Insulation Properties

With an R-Value of 6.2-6.5, SPF roofing provides superior insulating properties, acting as an airtight barrier that prevents outside air from penetrating the structure and inside air from escaping through the roof.

If you aren’t familiar, R-value is a term used to measure the ability of a material to resist the transfer of heat. The higher the R-value, the more resistant the material is to heat transfer.

According to, “Polyurethane foams have one of the highest insulating R-values per inch of all the available products on the market today.”

The high R-value of SPF roofing means significant cost savings on both heating and cooling costs. In many cases, building owners are able to recoup the installation cost of their SPF roofing in 10 years or less from energy savings alone.

Some have recouped their costs much more quickly. For example, Energy studies performed by Texas A&M University on their own roofs, “show the energy cost reductions obtained by applying SPF to more than 8 million square feet of roofing paid for the cost of the retrofit in a little over three years.”

White Reflective Surface

In addition to its superior insulating abilities, SPF roofs are also considered cool roofs, featuring a white, reflective top coat that reflects UV rays and keeps roofs up to 50 degrees cooler, for savings of up to 35% on building cooling costs.

This white, reflective barrier, made up of silicone and embedded granules, is sprayed over the insulating foam as the final step in the SPF roof installation process. This additional layer protects the roof from sun damage, excess heat, weather, and impact.

Less Strain on Your HVAC System

The superior reflective and insulating powers of SPF roofing mean less strain on your building’s HVAC system. By preventing excess heat or cold from penetrating your building, an SPF roof will help the system run more efficiently and prolong its life. You’ll also reduce your costs for HVAC repairs and maintenance over time.

Longer Lifespan of Your Roofing System

When properly maintained, an SPF roofing system can last over 50 years. That’s a substantial cost benefit when compared with many commercial roofing systems with useful lives of just two decades.

In addition, maintenance costs for SPF roofing are minimal. The roofing system should be inspected by a professional roofing service contractor twice per year, typically in the spring and fall.

SPF roofing can easily be refreshed and repaired with additional layers of SPF foam or a re-application of the white, reflective topcoat. That means worry-free protection that prevents leaks, keeps your building more comfortable, and provides substantial savings over the long haul.

By providing an effective, airtight barrier from outside air, reflecting UV rays and excess heat, reducing the load on your HVAC system, and providing a long lifespan of leak-free protection, your SPF roof could more than pay for itself with years of faithful service.
