Companies that produce roof shingles typically recall them because problems such as cracking and lifting occur, and the number of these reports increases over time. Defective raw materials or an error during the manufacturing process usually causes these shingle problems.
Reports of roof flaws have often involved asphalt shingles, but premature deterioration has also affected concrete shingles. Consumers who purchased faulty roof shingles have some recourse through class-action lawsuits, although any money recovered may be for the price of the shingles only and not for the cost of the roof installation. Companies that have faced class-action lawsuits because of defective roof shingles include CertainTeed, GAF, Owens Corning and PABCO.
