Warranties, Materials, and Contractors

Different grades of materials can be used for roofing projects. The grade of material helps determine the expected life of the roof. Be sure you have the product you specify.

Check to see that the contractor is familiar with the product the contractor is installing and that the contractor is reputable. If you have a question about a contractor, you can check with the National Roofing Contractors Association for more information.

Some products have a warranty that covers the workmanship of the materials used. The contractor may specify a warranty for installation of the roofing system. Get this information before the job is started.
