Classic Metal Roofing

Tuff-Rib / Classic Rib Metal Roofing

Our most popular panel, Tuff-Rib / Progressive Metal Roofing Panel is a great choice for both residential and commercial purposes. It is the most economical panel we carry. Tuff-Rib is also known under other names including MasterRib, Panel-Loc Plus and GrandRib 3. Available with a 40 year paint warranty, Tuff-Rib is a long lasting economical metal roofing or siding product that comes in many Energy Star approved energy efficient colors.

Lasting Strength

Tuff-Rib is an extremely durable metal roofing alternative to other materials, starting from the metal to the baked on paint finish. We start with quality high tensile steel, coat it with a tough Galvalume® zinc-aluminum coating, pre-treat it with primer, coat it with a baked-on enamel 40 year warranted siliconized polyester paint system, then roll-form it to your specified lengths.

Because we cut Tuff-Rib panel lengths to the half-inch, you will save money on materials due to less waste, and time when you go to install them. A full line of trim and accessories is also available.

Watertight Design

Whatever you are using it for, Tuff-Rib performs. The trapezoidal ribs feature a built-in water siphon channel, which means that when extreme blowing rains try to get between the laps they are promptly siphoned down the panel. Just one more way that Tuff-Rib is superior to other systems.

Evident Beauty

Tuff-Rib is available in a variety of colors to match any home. Whether your home’s walls are vinyl siding, brick, or almost any other material, we have a color that will compliment it.

The Economical Choice

Tuff-Rib is not only beautiful; it is also our most economical metal roofing panel.
Whatever your project type, Tuff-Rib can fit the bill.
