Justin Dorminey Joins GB Sales Team

GB Sales would like to welcome Justin Dorminey to our sales team. Justin will be responsible for growing our portfolio of product sales, including Polyglass, Hunter Panels, and USG Securock in Alabama and North Florida. We are excited to have Justin on board.

With over a decade of experience in the commercial roofing industry, Justin had the unique opportunity to work on both the manufacturer and distributor sides of the business. Along the way, he gained invaluable knowledge, built strong industry relationships, and developed a well-rounded understanding of the roofing world from multiple angles. Justin enjoys the day-to-day problem-solving the industry requires and deeply understands commercial roofing systems.

Originally from Tallahassee, Florida, Justin is a proud graduate of Florida State University, where he earned his bachelor’s degree. He confesses to still be a “die-hard Seminoles fan” even when it’s not easy. Ourside of work, Justin enjoys spending time with his wife, Katelynn, and their two daughters, Charlotte and Claire. When offered the chance, you can also find him on the golf course – chasing birdies and enjoying the game.

WHERE THE ROOFING MATERIALS ARE BEING USED

Project Spotlight

This commercial roofing project on the Ochsner Health System “Super Clinic” in Metairie, LA has been featured on many roofing professional platforms (like RoofingContractor.com).
 
Carriere-Stumm from New Orleans, LA was the Polyglass certified installer on this project. The facility is a three-story, 185,0000-square-foot “super-clinic” occupying the old vacant Sears building at Clearview Mall. Roofing included installing a cover board layer over a Polytherm ISO hot-mopped system laid on the concrete roof deck. They completed the installation with a dual torch-applied system with Polyflex Smooth as the base layer and Polyflex G FR as a fire-retardant cap layer.
