CertainTeed roof shingles might be defective and deteriorate prematurely.

Investigation and pending class action lawsuit against CertainTeed Corporation alleging that CertainTeed markets and sells shingles which were defectively designed and manufactured such that they prematurely and unreasonably deteriorate by blistering, crumbling, curling, cracking, pitting, balding, and leaking.

CertainTeed manufactures roof shingles. The investion has led to a series of class action lawsuits filed on behalf of individuals and entities that have owned, own, or acquired homes, on which CertainTeed shingles are or have been installed. The class action lawsuit allege that CertainTeed has knowingly and intentionally concealed the fact that its products were and are defective by representing, advertising and warranting that their shingles would be durable and free from manufacturing defects. CertainTeed's shingle warranty claims to guarantee that its asphalt shingles will be free from manufacturing defects for a specified length of time for each brand, ranging from 20 years to lifetime.

Despite its warranty, CertainTeed has failed and continues to fail to repair or replace defective shingles or to correct the manufacturing defects in the CertainTeed shingles. Further, the installation of defective CertainTeed shingles results in damage to the underlying roof structure as well as the necessity to replace the shingles prematurely. The allegations against CertainTeed include breach of express warranty, breach of implied warranty, negligence, violations of consumer protection laws, breach of contract, fraudulent misrepresentation, negligent misrepresentation, unjust enrichment and strict liability. CertainTeed, a Delaware corporation, is a manufacturer of building materials including roofing, siding, insulation, windows and patio doors, fence, decking, railing, foundations and pipe.
