When you see that a contractor has a license, you automatically know that they know the latest best practices for roof installation, repair, and maintenance including all relevant permitting rules. There are no state roofing license requirements for roofing contractors in Georgia as they are considered an Exempt Specialty Contractor by the  State Licensing Board. However, Regal Roofing is HAAG Engineering certified, so you can be sure you are working with a qualified and experience roofing company.
