Types & Gauges

Metal roofing systems are often categorized by two defining characteristics: the gauge of the metal and the method (type) in which the panels connect to the roofing structure.


The American Iron and Steel Institute defines gauge quite simply – the thickness of sheet steel.

The lower the number associated with the gauge, the thicker the steel is, meaning a 26-gauge sheet is thicker and heavier than a 29-gauge sheet.

Weather Tite offers roofing materials that are 26-gauge and 29-gauge, the most common choices for residential roofing, light commerical use, as well as, agricultural applications.. Other gauges are available on special request.


Exposed Fastener

An exposed fastener metal roofing system uses panels that overlap and connect using self-drilling fasteners that connect directly to the roofing structure. They come in agricultural, commercial and residential profiles. Exposed fastener systems allow for easy installation and simple removal of a single panel if something were to happen to require a replacement. Weather Tite offers several panels of this type.

Standing Seam

A standing seam metal roofing system also uses panels that overlap and connect, but they are fastened to the roofing structure through a series of clips and fasteners that are hidden underneath. Standing seam systems represent the latest technology in commercial and residential metal roofing, allowing the panels to expand and contract based on weather and environmental changes. Weather Tite offers a variety of panels of this type.
