ONDURA Corrugated Asphalt Roofing Panels

ONDURA is a North American line of lightweight corrugated bitumen roofing panels sold by Onduline North America. Current products use bitumen sheet reinforced with cellulosic fibers and thermosetting resin, with inorganic pigments for color.

Onduline markets the ONDURA Premium Series for auxiliary and outdoor structures such as sheds, garages, agricultural buildings, workshops, and similar projects. Before specifying it for an occupied home, confirm the exact product’s code approval, fire classification, wind design, deck, slope, snow-load, and local installation requirements.

Company History and Ownership

Onduline began making corrugated cellulose-and-bitumen roofing in France in 1944. The company established North American production in Fredericksburg, Virginia, during the 1970s. Onduline now operates in more than 100 countries.

Onduline has been part of Kingspan Group since September 2022. Onduline North America remains based at 4900 Ondura Drive in Fredericksburg.

Current Product Line

The current North American technical library lists ONDURA Premium 9, Premium 10, Premium Half Sheet, and Edge profiles. Sizes, usable coverage, weight, fastener count, colors, and support requirements differ by profile.

For example, the Premium 10 technical data sheet lists a panel 79 inches long and 38 inches wide with 10 corrugations. It weighs about 14.4 pounds and provides about 17.7 square feet of net coverage after the specified overlap. Listed colors are red, green, brown, and black.

Do not use dimensions or coverage figures from a different ONDURA profile. Calculate with net coverage, not the panel’s gross area, and add the manufacturer’s allowance for cuts and waste.

Slope, Deck, and Support Requirements

Follow the profile-specific data sheet and installation guide. The Premium 10 sheet, for example, permits a 2:12 slope on decking only with additional waterproofing and larger laps. It permits 3:12 on decking without those added requirements and 4:12 on purlins at the stated maximum spacing. Other profiles may differ.

Snow load, roof geometry, occupancy, local code, and panel profile determine whether decking or purlins are suitable. The manufacturer recommends decking in heavy-snow areas. Have a qualified designer or building official confirm structural and code requirements for the project.

Installation

Installers can cut and fasten ONDURA panels with common tools, but layout and detailing matter. The current installation guide covers overlap, fastener placement, support, ridges, valleys, eaves, wall connections, and safety.

Use the fastener type, length, washer, quantity, and placement specified for the selected profile. Incorrect nailing, insufficient support, short laps, damaged panels, or missing flashing can cause leaks and may affect warranty coverage.

Roof work presents a fall hazard. Secure ladders, use required fall protection, wear eye protection, and avoid work during high winds, storms, or slippery conditions. Do not walk on wet, dusty, frosty, or oily panels.

Advantages

• Low panel weight: Lightweight sheets can simplify handling on suitable small structures.
• Common tools: The panels can be cut with a hand or circular saw and fastened with the approved nails or screws.
• Roof-over options: Some projects can install ONDURA over existing roofing when the current guide, substrate condition, structure, and local code permit it.
• Recycled fiber content: Onduline reports recycled cellulosic content in its bitumen sheets. Ask for current product-specific environmental data if that affects the purchase.

Tradeoffs

• Limited applications: A product intended for an auxiliary building may not meet the requirements for a house or other occupied structure.
• Profile-specific detailing: Coverage, supports, laps, and fasteners cannot be mixed across products.
• Color and weathering: Confirm available colors and the current finish warranty. Ordinary fading, surface damage, and maintenance may have separate terms or exclusions.
• Local approvals: Verify fire, wind, structural, and building-code acceptance for the exact location and assembly.

Environmental Claims

An archived U.S. Environmental Protection Agency procurement listing identified an earlier Ondura product as recovered-cellulose roofing material. EPA does not endorse individual products, so that historical listing is not a current “Environmentally Preferred Product” certification.

Compare current recycled-content data, service life, maintenance, transport, and end-of-life options for the exact product. A broad environmental label cannot replace product-specific documentation.

Warranty

Warranty terms depend on the product and purchase date. Obtain the current ONDURA warranty from Onduline North America or the seller before purchase. Retain the receipt, product labels, installation records, and photographs.

Current company literature says product registration can help preserve purchase information but is not necessary to file a future claim. Follow the installation guide, since mistakes can affect coverage. Confirm the term, prorating, finish coverage, labor, removal, replacement material, transfer rules, and exclusions in writing.
