(For use with the Ondura Corrugated Asphalt Roofing System. Ondura Ridge Tiles are used for finishing the roofing project at the peaks and hips.) Attractive and affordable, the Ondura Corrugated Asphalt Roofing System is ideal for a variety of applications, including residential, commercial and agricultural jobs . . . as well as for re-roofing and DIY projects. Also, Ondura is recognized by the EPA as an Environmentally Preferable Product, making it the "greenest" roofing material on the market. And it comes backed by the industry's only Lifetime Limited Warranty! Ondura's very construction makes it different, and makes it a superior roofing and siding material at the same time. Its corrugated design enables it to be both lightweight and strong, while its total asphalt impregnation means it outlasts most other roofing (including metal). Ondura is easy to cut and install, even over existing roofing, like metal or asphalt shingles. It can also be applied over solid decking or open purlins (sheets only; non-residential structures). In a re-roofing application, you're spared the bother and expense of having to tear off and dispose of an old roof. And that makes re-roofing easier, faster, and cheaper. That's why Ondura is quickly becoming one of the most popular re-roofing materials ever. Ondura is the perfect problem solver, sealing out leaks, holding down costs, and recycling buildings with new, handsome roofing and siding. Available in 8 attractive colors, in a unique appearance that complements both contemporary and traditional style homes.
