A company that is confident in their work will always be willing to offer a warranty on their work. This can also be a good indication that they are not using quality roofing materials. All roofing companies should be willing to offer a warranty, but not all roofing companies offer warranties. Ask your roofing company if they offer warranty on their work. If they do not offer a warranty, it is a good sign that they may not be the right company to hire. Our roofing company offers one of the longest warranties in the state of Georgia. We have a lifetime, no leak guarantee.
