How Long Does Spray Foam Roofing Last?

Spray foam roofing is a material that is sprayed as a liquid and then converts into a foamy texture to create a solid layer across an existing roof. Spray Polyurethane Foam is created by combining isocyanate (A) and polyol (B) with ample heat and pressure. It is applied directly with a specialized spray. These roofing systems are the best solution to improve energy efficiency and provide interior comfort.

Spray foam roofs are growing in popularity because of their durability and sustainability. They are one of the best roofing solutions that can last longer. But how long will your spray foam roof last? How is it sustainable? And how do you maintain a spray foam roof to make it last longer?

How Long Does Spray Foam Roofing Last?

With proper maintenance and recoating, spray foam roofing may last a very long time. Consider 30 years at the minimum and 50 at the maximum if the roof has been cared for properly. The roof's overall lifespan is also determined by its exposure to different factors like weather conditions. It is advised to perform roof maintenance inspections twice a year. 

Factors Impacting the Cost of a Commercial Spray Foam Roofing

The average spray foam roofing cost usually starts at $8 per square foot, including the basic materials and labor. This price may vary depending on several variables, including the difficulty of installation, the required R-value for your roof, the desired warranty length and thickness, any additional coverings you might want to add, etc.

Several other factors which are responsible to impact the cost includes: 

  • The Roof Size
  • The Number of Penetration
  • Percentage of Wet Insulation in Your Roof
  • Contractors Experience
  • R-value of the Roof
  • Amount of Preparations Required
  • Roof Access to the workers

Recommended Thickness and Warranty Length of Spray Foam Roofing

A material's insulation and resistance to heat flow are measured by its R-value. To increase insulation and cut down on energy bills, the R-value of your commercial roofing should be high. However, it is essential to recognize that thicker foam installations sometimes mean a higher R-value. 

Therefore, roofing professionals usually recommend a 10-year warranty with 20 miles of coating installed on the roof. Timely inspections should keep the damage to a minimum. However, due to weather and other factors, your roof may still get down to 7-8 miles of the coating after nearly a decade of wear and tear. 

How Is a Spray Foam Roof Sustainable?

Spray foam roofs are sustainable because they are long-lasting and significantly reduce energy costs. The high R-value of spray foam and the reflective and light-colored coatings that are applied on top of the foam primarily ensure the sustainability of spray foam roofs.

Another contributing factor is that the foam is used above the roof deck rather than on it, significantly reducing thermal bridging. If your commercial roofing is adequately maintained over the years and is checked for damages by a roofing contractor, you won't need to replace your roof for at least another 30 years.

Spray Foam Roofing Maintenance

Maintaining and properly caring for your roof will significantly benefit its durability and help you save more on energy bills for extended periods. Here are a few ways you can maintain your spray foam roof:

1. Regular Roof Inspections

Having a roofing contractor examine your commercial roof once a year is sufficient. But it's important to remember that inspections are necessary to increase your roof's lifespan.

2. Carefully Inspect Damages on the Roof

Inspect a roof on your own to properly look for roof damage. You may want to pay close attention to splits, cracks, and tiny holes on the foam's surface, as they may result in significant damage from exposure to UV rays. Also, flashings, ribs, drains, and roof edges must be examined. Hiring a roofing contractor to inspect your commercial roof thoroughly is best.

3. Keep Your Roof Clean

Clean your roof to keep it in good shape. You can handle most of the cleaning, including clearing tree branches and other debris. However, your roof should be cleaned after a storm and inspected for damages by professionals.

4. Examine the Roof Texture

Your commercial roof should have the texture of an orange peel. Look for any discolorations or changes in the surface of your roof during the inspection. If the texture of your roof is similar to scrambled eggs or popcorn, you should be concerned. In this case, take immediate action toward roof maintenance.
