Question about Plastic Roofing Products:
Do you have any information on an Owens Corning plastic roof shingle? It’s not made anymore and I didn’t know why it got pulled off the market.
Reply:
Plastic roofing shingles, tiles, slates, or "wood" shingles are manufactured using polymer-based or composite materials that may offer improved impact resistance (such as resistance to hail damage). Polymer-based or plastic roofing products are generally about the same weight as laminated asphalt roof shingles, therefore lighter than cement-based shingles, clay roof tiles, or slate roofs.
 Owens Corning, to address your question, produces a number of plastic roof products: roof vents, banding material, foam insulation, and plastic roof cement. But their site [web search 05/20/2010] did not turn up plastic roof shingles nor information about the discontinued Owens Corning plastic shingles that you cite.
However in 2002 Handy Magazine reported that Owens Corning was distributing Mira Vista, a composite shingle made of fiberglass, ground clay, and slate. That product was subject of a Mira Vista class action lawsuit settled in 2007. Mira Vista image at above left - Birka White.
Here is a quick list of common roofing plastic and synethetic materials. Our roofing inspection, diagnosis, repair and installation articles listed at left and below provide roof inspection, roof leak or problem diagnosis, roof installation, and roof repair information as well as details about the factors that affect the life of any roof. We include roof warranty and claim information and links to roofing product sources.
A number of companies produce plastic or recycled plastic roof coverings in a variety of styles that look a lot like clay tile roofs, cedar shingles, slate roofs, wood roofing, and even asphalt shingle roofs. Here are some examples:
- Authentic Roof", developed in Canada by Crowe Roofing Products in about 1992 was one of the first plastic roof products that used thermoplastic olefin/rubber and was sold in panels of seven or eight-wood-shake sections. The company currently produces slate-like roofing polymer-based "plastic" roofing products.
- Eco-Shake, Re-New Wood, is a vinyl and wood fiber product sold in a form resembling wood roofing shakes.
- Flex-Shake, U.S. Century, uses recycled rubber tires and crushed slate to produce slate-like roofing shingles.
- Mira Vista, Owens Corning, a composite shingle made of fiberglass, ground clay, and slate, 2002, subject of litigation and settlement, reported below.

Many of these plastic roofing product producers call plastic roofing a "green" product - giving plastic roofing materials credit for using recycling, and some products are reported to be made entirely of recycled plastics. Molded polymer roofing products offer an increased impact-resistance over some other roofing materials, making them a possible candidate for areas where hail damage to roofs is a concern. Also see HAIL DAMAGED SHINGLES.
- Corrugated fiberglass roof panels are a fiber-reinforced plastic roofing product whose origin may be traced to the Owens Corning Corporation in the 1960's when O.C. developed fiber-reinforced plastic underground storage tanks. We illustrate and discuss corrugated fiberglass roofing at CORRUGATED ROOFING.
Owens Corning Mira Vista Plastic Roof Shingle Class Action Lawsuit & Settlement
According to Birka-White, a law firm who handled the case, a roofing product case settled by The Birka-White Law Offices in 2007 involved Owens Corning "MiraVista" shakes manufactured by Owens Corning, Molded FiberGlass Companies and Molded FiberGlass Companies West between 1996 and 2002.
MiraVista was manufactured largely from fiberglass resin and inorganic fillers. The case was prosecuted in the United States Bankruptcy Court, District of Delaware, Case No. 00-3837. On January 23, 2007, the Court granted final approval of the settlement which consists of $11 million dollars plus optional replacement MiraVista shakes.

http://www.owenscorning.com Owens Corning is credited as the inventor of fiberglass when Owens Illinois [O-I] researcher Dale Kleist and his colleague John Thomas stumbled onto and then realized the significance of producing glass fibers in 1932. O-I formed a joint venture with the Corning Glass Works in 1935, leading to the formation of Owens Corning Corporation in 1938. More on Owens Corning's history is at
