When shopping for a roofing contractor, you'll see terms like 'GAF Master Elite,' 'Owens Corning Preferred,' or 'CertainTeed SELECT.' These certifications sound impressive, but what do they actually mean for you as a homeowner? Let's break it down.
What Are Manufacturer Certifications?
Major shingle manufacturers like GAF, Owens Corning, and CertainTeed offer certification programs that recognize contractors who meet certain standards. These programs typically require:
- Proper licensing and insurance
- Training on the manufacturer's products
- Demonstrated installation competence
- Good business standing and reputation
- Minimum volume or experience requirements
Certified contractors gain access to enhanced warranty programs and marketing support. Homeowners gain confidence in installation quality.

Why Certifications Matter
Enhanced Warranties
This is the primary practical benefit. Standard shingle warranties cover only manufacturing defects—not installation problems. Enhanced warranties through certified installers add workmanship coverage, meaning if the roof fails due to installation issues, the warranty still applies.
A 50-year shingle warranty means nothing if improper installation causes failure in year 5. Certified installer warranties protect against this.
Installation Quality
Training requirements ensure contractors know proper techniques for the specific products they're installing. Different shingles have different requirements—fastener patterns, alignment, accessory products. Certified contractors are trained on these specifics.
Accountability
Manufacturers maintain oversight of certified contractors. Poor performance can result in losing certification. This creates incentive for contractors to maintain quality—their certification status is valuable.
Certification Doesn't Guarantee Excellence
Certifications are valuable but not sufficient alone. They indicate minimum standards, not maximum quality. A certified contractor who meets only minimum requirements may not be your best choice.
Still evaluate:
- Local reputation and reviews
- Years of experience in your area
- Communication and professionalism
- Detailed written proposals
- References you can verify
Certification plus strong local reputation is the combination to seek.
Questions to Ask About Certification
- Are you certified with the manufacturer of the shingles you're proposing?
- What specific warranty coverage does your certification provide?
- How long have you maintained this certification?
- Can I see documentation of your certification status?
Legitimate contractors are happy to answer these questions and show proof of certification.
