You probably have experience with traditional foam ridge vents. It’s only a matter of time until the foam starts working loose and then falls out from under the ridge cap. Snap-Z’s innovative design uses absolutely no exposed foam so it’s impossible for it to slip out of place, thus resulting in maintenance-free ventilation. With 16 colors to choose from, you can also match the ridge vent to the color of metal you are working with. Snap-Z’s coatings are fade-resistant for a long-lasting color match. Snap-Z in Eco-Black ships the next day. Eco-Black gives you the most ridge vent for your money compared to other colors. The matte black color works great with any color roof because the color contrast is hidden in the shadow line.


Steel Shield is specifically designed for the installation of steel panels directly over asphalt shingled roofs. The exceptionally durable membrane protects the underside of the steel roofing panels against abrasion due to temperature change expansion. Steel Shield saves the time and money typically spent when applying an additional vapor barrier, while eliminating the need for furring strips. Steel Shield can also reduce the need for walking boards since it is factory applied during the panel production process and shows up installed on the panels. From the makers of DripStop.
