Ondura® sheets and tiles are being seen on roofs everywhere. Ondura® gives your roof the attractive look of more expensive tile, but without the weight and costly installation. It has a distinct appearance that looks great on traditional as well as contemporary homes.
Ondura® sheets and tiles install easily. The easy-to-follow Installation Guide takes you step-by-step through the process, from estimating materials to handling hips, valleys, and flashing. Ondura® sheets and tiles are lightweight and do not have sharp edges, making them easy to handle, even for one person! Ondura® can be easily cut and no special tools are required.
Ondura® sheets and tiles are made of a tough organic fiber core that is totally impregnated with asphalt, one of nature’s best preservatives. Because it is made this way, colorful Ondura® comes with a Lifetime Limited Warranty, one of the strongest warranties in the roofing industry. It guarantees that Ondura® will replace any sheet that is found defective in workmanship or materials for as long as you own the structure where Ondura® has been installed.
Ondura® vs. Shingles in Residential Applications
Selecting a new roofing system is not easy; there are many options available and, like most other building products, each roofing system has its pros and cons. Shingles remain one of the most popular roofing products, though they have a variety of drawbacks. High-grade shingles are expensive and are vulnerable to a number of types of weather damage. They can blow off in high wind, curl or bake from underneath in high heat, and they can allow melting ice to seep below to the underdecking and other materials. They offer very little thermal protection, meaning they can transfer heat to and from your home. Shingles also add considerable weight to the roof ranging from 210-360 pounds or more per 100 square feet. Also, if installed improperly, an unattractive “zipper” pattern can appear.

Ondura® vs. Metal in Residential Applications
Metal is regarded as one of the most durable types of roofing, yet it has numerous weaknesses. Metal is traditionally an expensive roofing choice. Not only are the materials pricey, but professional installation and maintenance also add to the cost. Metal is susceptible to rust and corrosion, and metal roofs can be noisy during rain as well as during expansion and contraction. It is inclined to have aesthetic problems such as “oil canning”, where irregular waviness or dimples occur in flat areas of the panel (often due to expansion and contraction). Lastly, metal extraction, refining, transport, and production are energy intensive.
- Costs less than painted metal roofing panels and is often less expensive than unpainted galvanized metal roofing.
- Is simple to install with common tools.
- Will never rust or corrode.
- Is quieter than metal, as it dulls the sound of rain, wind, and hail.
- Has a distinct appearance that is not affected by expansion or contraction.
- Is an environmentally preferable product made from 50% recycled materials.
- Comes backed by a Lifetime Limited Warranty (while some metal roofing carries no warranty).
