Ondura sheets and tiles are showing up on roofs everywhere. And for good reasons. Ondura gives a roof the attractive look of more expensive tile, but without the weight and costly installation. Ondura can be applied directly over even surfaces like asphalt shingles or over uneven surfaces by first installing nailing strips. In a re-roof application, that saves you the bother and expense of having to tear off an old roof. And that makes re-roofing easier, faster, and cheaper.
Ondura sheets and tiles are made of a tough organic fiber core that's totally impregnated with asphalt, one of nature's best preservatives.
