What is a 5V roof?

Monday, October 4, 2021

“5V” is the shortened name for a 5V-crimp metal roof. It is the traditional profile for a metal roof, named for the five inverted V’s running down the length of each panel, two at each end and one in the middle.

    Most 5V-crimp roof panels produced in the last 30 years are made of Galvalume®, which is a steel core with a combination zinc and aluminum coating, and they are secured with screws to the roof deck. An example is shown at the top of the page. Older roofs are galvanized steel secured with nails, like in the photo below.
