Can SPF roofing withstand hail?

Baseball-sized hail stones - St. Louis 2015

The Midwest region and St. Louis are known for getting pounded with hail from Memorial Day to Labor Day. Even if a twister or two is not in tow, a hailstorm can inflict devastating damage on a commercial roof. Some business owners wonder if SPF is rough and tough enough to withstand the impact of hailstones. Can Spray Polyurethane Foam really protect a roofing substrate during a hailstorm?

Those were the types of questions asked by the Performance Base Studies Research Group (PBSRG) at Arizona State University. The PBSRG conducted a controlled test of elastomeric-coated SPF roof systems with a two-fold purpose:

  1. Determine the “relative performance of [the] different SPF roof system products by applying “information theory” based by laboratory tests, by testing the existing in-field installations, and by quantifying the past performance;
  2. Identify whether a properly installed SPF roof system is a viable option to reduce the risk of future hail damage.” (NRCA)

The test results provided exact confirmation of what our SPF experts have believed for years: SPF roofing not only stands up well to the beating of hail, but SPF roof systems are actually some of the best, if not the best, commercial roofing systems at resisting the effect of hail. According to the PBSRG study, polyurethane-coated SPF roofing systems generated the highest hail resistance of all elastomeric-coated SPF roofing systems.

We’ve seen SPF roof systems perform phenomenally well through hail storms compared to other commercial roof systems and have the pictures to prove it. Hail stones the size of baseballs can pound a metal roof and create cavernous openings when the impact sheers away entire panels. The same storm created only isolated surface punctures in SPF roof systems that were quickly and easily repaired.

Our experience at R&A Contracting with SPF roofing further shows that SPF roof systems are less costly to repair after hail damage compared to any other commercial roof system. SPF roofing is also the most wind-resistant form of commercial roofing due to its monolithic bonding installation. There’s no question: SPF roof systems are the most durable commercial roof systems.

I’d be an idiot if I did not take this opportunity to communicate to you how much we appreciate the way in which you conduct business and take care of our facility. In my experience you, and your team, are at the top of the list of all the roofing companies I’ve dealt with over the years. Thank you!

Eric and crew were really nice to have around. They were courteous, careful and caused little if any disruption. Their work looks good too! To be honest… a good experience with a product that I initially had misgivings about. I’m a convert because of Bubba, Sam and Eric. Thank you.

“I want to thank the crew at R&A for a job well done on our very leaky roof at the shop. It is certainly nice to have the drips and rivers gone from the shop when it is raining. I also wanted you to know how much we appreciated that the guys were able to stay out of our way and allowed us to do business as usual without any problems or interruptions. The roof looks great and the clean-up after the job made it so we couldn’t even tell you’d been here. Thanks for doing what you do so well!”

Jay Moore, President of Safe Way Tire and Auto Center

“My wife and I were on vacation when water pipes burst in our house. We got a hold of Craig and the R&A crew was able to start evacuating the water immediately. The best part was that they were able to start work before we even returned home. It was a very fast turnaround considering the extensive amount of water damage.”

“Craig and Mike came out in a timely fashion when we needed the work done. They did a reliable and quality job.”

Jerry from SLR Properties

“Craig helped us out tremendously with the insurance process. Timely and very professional.”

Lindell from Greater Missouri Builders (GMB)

“We purchased a house and there was some damage to the roof. Very impressed with the thoroughness of Mike’s inspection. Very comfortable with their explanation of what needed to be fixed. Most impressive was the way they protected our landscaping. Really liked the way they treated me as a valued customer, even though it was only a small project.”

Ross from Troy, MO

“I use R&A Contracting when my commercial roofs receive storm damage. They work on our behalf through every step of the insurance claim process. They perform all of the work and complete the insurance process, making our roofs better than they were before the storm.”

Director of Facilities for a large Property Management Company

“The team at R & A Contracting responded immediately when notified of our water disaster. They removed water-damaged materials and property quickly and restored our home even before the final settlement from our insurance company. They minimized how long our family had to live in a hotel and got us back to normal as fast as possible.”
