Common Questions About Contractor Certifications

GAF Master Elite® is GAF’s highest contractor certification level, held by fewer than 2% of roofing contractors in North America. Earning and maintaining Master Elite status requires passing GAF’s training and quality standards, remaining properly licensed and insured, and demonstrating a commitment to ongoing education. Master Elite contractors can offer GAF’s Golden Pledge® Warranty — a 25-year labor and materials warranty that standard GAF contractors cannot provide.

Yes — for two important reasons. First, many manufacturer warranty programs are only available through certified contractors. If your roof is installed by an uncertified contractor, you may only receive a standard material warranty, not the enhanced coverage that certified installation unlocks. Second, certified contractors are required to install to manufacturer specifications, which affects long-term performance, warranty eligibility, and code compliance. Certification is the manufacturer’s way of verifying that the contractor actually meets their standard.

CertainTeed ShingleMaster™ is CertainTeed’s highest residential roofing contractor credential. Earning ShingleMaster status requires passing CertainTeed’s SELECT ShingleMaster™ exam, meeting experience and insurance requirements, and maintaining the credential annually. ShingleMaster contractors can offer CertainTeed’s SureStart Plus™ warranty — an extended labor and materials warranty that covers the full replacement cost of both shingles and workmanship on qualifying installations. Mr. GoodRoof has held ShingleMaster status since 2018.

Improper skylight installation is one of the most common causes of roof leaks. VELUX certification requires completing VELUX’s professional installation training and meeting their installation standards. When a VELUX skylight is installed by a VELUX Certified Installer, it qualifies for VELUX’s No Leak Promise — a 10-year installation warranty on both labor and materials. Without a certified installer, that labor warranty is not available, and improper installation can also void the product warranty.

Each manufacturer maintains a public contractor directory. You can verify GAF Master Elite® status at gaf.com, CertainTeed ShingleMaster™ status at certainteed.com, and Malarkey Certified Premium Contractor status at malarkeyroofsource.com. BBB ratings are publicly searchable at bbb.org. Mr. GoodRoof’s GAF profile, BBB listing, and certification status are all linked on this page.
