Wind Resisting Roofing

About

Technology Florida International University (FIU) is seeking companies interested in commercializing a High-Wind Resistant Concrete Roofing. This system reduces hurricane-induced damage, property losses and insurance costs, and enhances occupant safety, while being aesthetically attractive, and similar to the existing tile roof systems. The system’s structural and economic feasibility, constructability, and performance have been validated through detailed experimental investigations. Details of the investigations are available upon request. Hurricane-induced damage and property losses are due in large part to failure of roofs and water intrusion. To improve roof strength and performance, this system uses concrete panels reinforced by high-performance fiber-reinforced polymer (FRP) meshes. The system eliminates commonly used roof components and subassemblies such as wooden trusses, sheathing, underlayment, and shingles or tiles, which are most vulnerable in high winds. The new system replicates the shape and color of commonly used barrel tiles or other shapes, thus preserving the aesthetics of traditional roofing. Additional features are unimpeded and spacious attic space and increased interior volume underneath the roof. The system’s estimated cost is comparable to the cost of conventional roofing systems.
