What’s a building?

That may seem like a question for Captain Obvious, but not just anyone can build a stable, weather-insulated building. It’s important to know the fundamentals of building physics in terms of the structural demands of four or more walls, a foundation, and a roof. As material quality improved over time, from caves to rocks to wood and then metal, we’ve seen the evolution of building structure grow from thatch huts to the Empire State Building.

Let’s talk about walls. kenya dating sites free gives a great overview of the layer order for a building wall:

  • a rain control layer
  • an air control layer
  • a vapor control layer
  • a thermal control layer

No rain layer, your building interior has no chance of staying safe from wind and energy loss. Of course, Captain Obvious would also tell you rain brings water damage. What isn’t as obvious is that air can also bring moisture damage, like condensation and mold spores. Vapor can also bring water damage at a more microscopic level, albeit still potentially hazardous.

Even if you eliminate the effects of rain, air, and vapor, you still have to face the threat of thermal conduction or energy reduction. Temperature fluctuations, heat transfer, and UV exposure can alter a building’s environment stability. With all four types of layers intact, you can create a solid barrier against any energy loss.

That still leaves the roof. Andre’ O. Desjarlais of ORNL shares, “It is estimated that energy losses through roofs in the U.S. are increased by 70% because of the loss of insulation’s thermal resistance due to moisture contamination.” (ORNL) Spray Polyurethane Foam, or SPF as it’s often called, bonds with commercial roofing substrates to add a thermal control layer. This serves as the first line of defense for the roof against the heat transfer, UV conduction, and temperature changes throughout the seasons.

SPF applied inside the walls and over the roofing surface maximizes your building’s thermal control layer. We couldn’t be more impressed by how well SPF roofing has performed. Our R&A Contracting team is St. Louis’ expert in SPF commercial roofing. If you’d like to learn more, contact a member of our team today.

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.”
