What is a cool roof solution? - R&A Contracting

Is your building’s roof a “cool” roof? What does having a “cool” roof even mean?

July is just around the corner and it’s heating up across the Lou. A busy business owner doesn’t have time to dip their toes in the local pool. There’s work to be done, clients to meet, and money to be made while dipping in and out of AC-chilled interiors. You grab the mail on the way into the office and open your energy bill for the month. Wowza! You’re paying the equivalent of a small car loan to keep your office building cool each month. How do you keep your building cool without paying a small fortune?

You need a cool roofing solution for your commercial building. We call it a solution for a reason: paying too much for your AC is a problem that needs a solution. So, what is a cool roofing solution?

Virtually any commercial roof can be converted into a cool roof by applying a reflective coating. ENERGY-STAR defines a cool roof (or reflective roof) as having 65+% reflectivity and 50+% of emissivity after three years of aging. (ENERGY STAR) While the reflectivity rating is important, the emissivity rating may be even more important.

What does emissivity mean? A material, like metal, tar, and even SPF, has a special rate that it emits the radiance of the sun’s UV rays. If you leave a metal shovel out in the sun, the wooden handle may be a little warm to the touch but the metal part of the shovel may be much hotter, even burning your hand if you touch it. That’s because the wood naturally emits (releases) more of the sun’s radiance while the metal retains the radiance.

Let’s take that concept and apply it to commercial roofing. If you have an all-metal panel roof, your building is far more susceptible to letting the metal panels conduct the sun’s radiation into your building’s interior. This is because the metal has a low emissivity rating, which means that metal holds onto heat longer than most other materials.

Adding a covering of Spraying Polyurethane Foam (SPF) onto your existing roof surface creates a natural barrier against the sun’s radiation. This means your building is less likely to retain and conduct the sun’s heat into your attic and office space. By adding an acrylic-based reflective coating on top of your new SPF roof, you have increased reflectivity and emissivity to keep your building cool through the blazing days of summer.

If you’d like to learn more about installing a cool roof solution, we’d love to answer your next question.

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.”

Will from Dardenne Prairie, MO

“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.”
