Industry research by the U.S. Department of Energy (DOE) shows that U.S. buildings demand over 40 quadrillion BTUs of energy per year.

Commercial buildings account for more than 40% of total energy use, a massive draw on the overall energy demands of both energy production and business owners’ pocketbooks. (Source) A standard scale for measuring energy efficiency is the Leadership in Energy and Environmental Design (LEED) Green Building Rating System from the U.S. Green Building Council.

LEED Ratings for commercial buildings is typically divided into two categories: LEED-NC (New Construction) and LEED-EB (Existing Buildings). According to the U.S. Green Building Council, “LEED New Construction credits roofs with a SRI [Solar Reflectance Index] value greater than or equal to 78 for low-slope roofs, and 29 for steep-slope roofs, covering at least 75% of the roof area.  A lower SRI is allowed if more than 75% of the roof is covered, using a weighted formula.” (Source) The SRI (Solar Reflectance Index) is calculated off the slope of a roof and the total weight of roofing material. Translation: the slope of a roof affects how much energy is conducted into a building’s interior space from the roof.

So, how do cool roofing solutions factor into a building’s LEED Rating? The weight and density of a cool roofing solution, whether it be SPF (Spray Polyurethane Foam), metal roofing, or single-ply, can directly affect the SRI (Solar Reflectance Index) of a building’s energy retention and efficiency. In other words, the type of cool roofing solution has a direct affect on a commercial building’s energy efficiency (and energy costs!).

The independent Cool Roofing Rating Council and ENERGY STAR have taken great steps to provide accurate and helpful information for business owners considering different cool roofing solutions. Our R&A Contracting team takes great pride in studying and comparing each cool roofing solution for the best match to your commercial roofing needs. We are certified distributors of Lapolla Industries’ FOAM-LOK SPF cool roofing solution, a product which the U.S. Green Building Council offers LEED reward points for installation.

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.”
