History of the Screw, Metal Roof, and Adhesive
Humans have been connecting material using adhesives for thousands of years. Modern roofing companies are now using this tried-and-true technique to attach roofs with concealed fastener systems. The benefits of using adhesives for metal roofing are many, including the elimination of screw holes, reduced installation time, elimination of oil-canning and dimpling and more.

Adhesive begins to replace fasteners in different markets.
Early 20th Century
Commercial metal roofing projects begin popping up.
Metal roofing takes a setback due to leaks created by expansion and contraction of metal and roof vulnerability to screw holes.
Adhesives are used for weight efficiency, sonic vibration damping and aerodynamic smoothness. Also, used on satellites for space conditions.
Adhesives were introduced to alleviate the welding points and bonding was added into the production line for automotive development.
Adhesives are utilized to enclose framing for large outer areas, supporting the metal structure—making the train 25% lighter.
50 million cars, trucks and specialty vehicles and boats worldwide use structural adhesive bonding as established joining method.
