Shingle manufacturers offer long-term warranties ranging from 25 to 50 years, or even a lifetime. Roofing contractors, in most cases, recommend which shingle manufacturer to use and then the builder/property owner makes the decision primarily based on the product’s esthetics and the warranty information provided. Unfortunately, many building owners are confused or misled by the warranty details given, and assume the roof will last the term indicated on the package or the years as stated by the contractor. However, the warranty is generally not properly explained or fully disclosed, and it is based on manufacturing defects, not wear-life.
