How to prevent wind lift on your roof

Wind Lift Commercial Roof - R&A Contracting St. Louis

Is your roof capable of withstanding pre-tornado winds?

Thunderstorms in the summer and ice storms in the winter make St. Louis a tumultuous place for roofing to survive. Regular winds across St. Louis can often gust up to 50 m.ph., more than enough wind power to even cause wind lift of flat roofs in extreme situations. Here are some good examples of what wind lift can do to a roof.

Local county and state requirements vary for roofing systems, especially when comparing areas at risk for higher wind damage, as in the prime hurricane targets of Gulf Coast and Florida. Thankfully, St. Louis doesn’t experience hurricanes, but Midwest storm systems and the occasional twister or two are enough to put roofs at risk all across our city. You want to give your roof a fighting chance against high winds.

How to prevent wind lift for roofing systems

The best way to protect your roof against wind lift is to strap it down to your building structure. We do not recommend toe-nailing your roof members to your supporting walls. Use corrosion-resistant metal connectors, such as structural straps, to fasten your roof members to load-bearing walls.

Loss of roof sheathing is one of the biggest roofing weaknesses that can be exposed with wind lift. An exposed area of roof sheathing can lead to substantial water and wind damage inside your building or home. Start by using plywood at least 5/8″ for your roofing deck. If you’re installing flat roof panels, use the appropriate style of roofing fasteners, be it nails or screws, to secure your panels. Do not use staples to install roofing panels.

Check your attic for truss bracing. If there’s no evidence of truss bracing, install 2″ x 4″ boards the length of your attic space diagonally across trusses. Use high-grade screws to securely fasten the support boards to your trusses. You want a network of strategic brace boards that will hold your trusses together under the pressure of high winds.

If your roof is vulnerable to wind damage, our R&A Contracting team can help you reinforce and secure your roof before the next winds hit home. We help business owners across St. Louis find peace of mind knowing a solid, reliable roof is over your head at all times.

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.”
