Statistics show that the built-up roofs are a shrinking sector of the market nationally, but for many contractors, their built-up business is booming. Two large commercial contractors who saw a big boost in revenue from built-up applications in the past year are Advanced Roofing Inc., headquartered in Fort Lauderdale, Fla., and Empire Roofing, headquartered in the Dallas-Fort Worth area. The owners of these two hot companies in hot climates believe built-up roofs might be the longest lasting, most dependable roofs out there. Even as they kept a wary eye on asphalt fumes and the safety concerns that come with hot kettles, the folks at Empire and Advanced believe that BUR has a place in the future and for many buildings, BUR can be the right application for the job.
