The Average Cost of SPF Roofing Systems

The price of a spray foam roof ranges from $5 to $8 per square foot. These statistics primarily depend on the complexity and size of the roof structure as well as the thickness of the foam.

There are more aspects to take into account, including location, the roof substrate’s condition, the top coating material, warranty, etc.

It’s important to note that SPF systems have been shown to drastically lower a building’s energy costs, resulting in a significantly quicker return on investment.

Pros of SPF Roofing Systems

Energy Efficient

Easy Installation

Renewable and Sustainable

During its lifetime, SPF roofs produce minimal to no waste. The SPF roof is typically put on top of the original roof with little to no stripping of the previous roof, avoiding the need for costly roof tear-offs.

An SPF system also adds a protective coating to your entire roof.

According to Ken Byler, spray foam roofs also make use of environmentally friendly materials:

  • Low in the Emission of Volatile Organic Compounds
  • Zero Ozone Depleting Potential
  • Ultra-low Global Warming Potential
  • Free from Chlorofluorocarbons

Waterproof and Seamless

In conventional roofing systems, penetrations and seams are the main places where leaks occur; spray foam reduces this vulnerability.

Spray foam fills seams, gaps, and cracks in the roof because it is applied as a liquid.

The contractor can level out the roof and lessen the possibility of ponding water by applying polyurethane foam. 

Cons of a Foam Roof

Limited Application Window

SPF can only be applied to the roof surface during certain temperatures. You can’t install an SPF roof when there is frost, ice, visible dampness, or surface moisture on the existing roof.

Overspray Potential

The potential of overspray onto nearby cars and other surfaces exists since the SPF roof system is installed by a spray application.

Even though there is no health risk from this, the surrounding property is at risk.

Contractor Experience

“Not every SPF contractor is the same,” Byler wants to remind readers.

“Working with SPF calls for extensive product knowledge and the usage of high-end application tools and methods. Those who are thinking about installing a spray foam system should do their research to select a qualified SPF roofing contractor,” he added.

Ken Byler also states that the Spray Polyurethane Foam Alliance (SPFA) has a certification program with multiple levels that contractors need to pass.
