Kraft’s roofing installation crews are trained and certified to stringent manufacturer’s standards. That’s vitally important in this industry. Roofs installed by uncertified roofers can void the manufacturer’s warranty. A new roof is a big investment, typically involving thousands of your hard-earned dollars and lasting 25, 30, 40 years or more. As with any big investment, knowing in advance what your warranty covers could save you thousands if problems arise with your roof. Basically, there are two types of coverage that you should ask your contractor about: coverage against material defects and coverage against workmanship errors. Almost all roofing products come with a warranty against material defects, although your exact coverage will vary depending on the brand. It is important to remember that coverage against material defects is provided by the manufacturer, so you should select a brand from a manufacturer who is financially strong and therefore more likely to be in business for as long as you own your roof, which could be several decades!
