My contractor is offering a one-year warranty on my asphalt shingle roof system-is that the industry standard?
A. Before answering the question, a clarification needs to be made about the different warranties you will come across during your roofing project. First, there will be the asphalt shingle manufacturer’s warranty. In general, this warranty covers defects in the manufacture of the shingle. The period of coverage can range from 20 years to a lifetime. Please read NRCA’s consumer advisory bulletin addressing roofing warranties for more information. Once the project is complete, be sure the contractor provides you with a certificate for your records. Second, the roofing contractor will provide you with a warranty on his workmanship. Typically, this will cover installation and related issues. The warranty should contain what items are covered and what will void them. Many contractors offer one year or two years of coverage; however, there is no industry standard.
