What is the difference between a material warranty and a Workmanship Warranty Coverage on a new roof?

Workmanship Warranty Coverage is the guarantee we provide on the quality of our installation (the labor), typically covering leaks caused by human error for a period of 5-25 years. The Material Warranty comes from the shingle manufacturer and covers defects in the product itself. You need both to be fully protected, and our system covers both aspects comprehensively.
