It’s always a good idea to learn more about the warranty coverage included with your new roofing system. A good roofing warranty, after all, can add an extra layer of protection to your investment. And in cases where issues arise with the new system due to material defects or poor installation, you have greater peace of mind knowing its repair, or even its replacement, will be covered. But roof warranty coverage varies by manufacturer, so you’ll want to hire a roofing company that represents trusted industry names, such as GAF.
