What are the lawsuits against Owens Corning for their shingles?

Lawsuits against Owens Corning for their shingles have primarily involved older organic mat shingles from the 1980s and 1990s that experienced premature failure, cracking, and excessive granule loss. The most notable class action lawsuits were filed in the late 1990s and early 2000s regarding Owens Corning Organic shingles that were made with organic felt mat rather than modern fiberglass mat, which were prone to cracking, blistering, and leaking well before their warranty period. These lawsuits alleged that Owens Corning knew about defects but continued selling the product and inadequately honored warranty claims. Owens Corning settled several class action suits, offering cash settlements and replacement shingles to affected homeowners. In 2012, Owens Corning exited bankruptcy restructuring from earlier asbestos litigation unrelated to shingles. More recently, there have been smaller warranty claim disputes but no major nationwide class action like the organic shingle era. Modern Owens Corning Duration and Oakridge shingles made with fiberglass mats have not had major class action lawsuits. Owens Corning currently offers limited lifetime warranties and has a warranty claims process. Homeowners with older organic shingles from the 1990s who experience cracking should check if they qualify for any remaining settlement programs, though most have expired. Current fiberglass Duration shingles are considered reliable and not subject to major lawsuits.
