Manufacturer Certification Programs: GAF, CertainTeed & Owens Corning

What GAF Master Elite, CertainTeed SELECT ShingleMaster, and Owens Corning Preferred Contractor certifications actually offer new roofing businesses.

Why Manufacturer Certification Matters

Unlike solar's NABCEP or home inspection's ASHI/InterNACHI, roofing doesn't have one single dominant national certifying body — instead, the major shingle manufacturers each run their own contractor certification programs, which matter commercially because they unlock enhanced, transferable warranties that homeowners genuinely value and that you can use as a differentiator against uncertified competitors.

GAF Master Elite

GAF, one of the largest roofing manufacturers in North America, runs the Master Elite certification — limited to a relatively small percentage of roofing contractors nationally, with requirements around licensing, insurance, and a track record. Master Elite contractors can offer GAF's strongest warranty tiers, which is a genuine sales advantage when a customer is comparing bids.

CertainTeed SELECT ShingleMaster

CertainTeed's SELECT ShingleMaster program similarly recognizes contractors meeting volume, training, and reputation requirements, unlocking enhanced warranty options on CertainTeed products.

Owens Corning Preferred and Platinum Contractor

Owens Corning runs a tiered program (Preferred and Platinum Contractor levels), with the Platinum tier reserved for a smaller group of contractors meeting higher training and performance standards, similarly unlocking stronger warranty terms on Owens Corning products.

Is It Worth Pursuing as a New Business?

These programs typically require a track record (time in business, completed job volume) that a genuinely new roofing company won't have yet, so they're usually a year-one-or-later goal rather than a day-one requirement. None of them replace your state's contractor licensing requirement — they're a commercial and marketing credential layered on top of being properly licensed and insured, not a substitute for either.
