Three quotes for the same roof sit on the kitchen table. One letterhead carries a GAF Master Elite logo. Another has an Owens Corning Platinum Preferred seal. The third shows no badge at all. The question worth asking is what each badge demanded of the company, and what it lets that company put in writing for you.
How GAF screens a Master Elite roofer
GAF runs three contractor levels: Certified, Certified Plus and Master Elite. Home Team Construction, a roofer in Mastic, laid out what GAF digs into in a June 2026 post: proper state licensing, at least $1 million in general liability coverage, workers’ compensation, a look at credit ratings, liens and unresolved financial disputes, and Better Business Bureau standing. Master Elite asks more. Home Team says a company needs at least seven years in business just to be considered, then has to keep customer satisfaction high, take annual training and renew the status every year.
Ask how exclusive the program is and Long Island companies give different numbers. Safeguard Roofing, announcing its own Master Elite status from Bohemia in April 2021, said only 2 percent of roofing contractors had reached it. Home Team puts the share at 2 to 3 percent of roofers in North America. Roofing Contractor magazine, covering GAF’s award for top Master Elite firms in April 2024, said winners are picked from contractors that “must first demonstrate proper licensing (in states that require it),” so the licensing standard itself comes from government, not from GAF.
Owens Corning’s Platinum Preferred tier
Owens Corning’s contractor network has a Preferred tier and a Platinum Preferred tier above it. The plainest account of what the tiers are for sits in the company’s own warranty documents, both dated August 2026. Its Preferred Protection warranty must be installed by a Platinum or Preferred contractor and registered by that contractor within 60 days, and its workmanship period runs 10 years. Its Platinum Protection warranty requires a Platinum Preferred contractor, the same 60-day registration, and covers workmanship on a single-family detached home during the first 25 years.
Owens Corning’s contractor pages that we could read did not list the entry criteria for Platinum, so this guide does not repeat the ones circulating on contractor sites.
CertainTeed’s ShingleMaster ladder
CertainTeed starts with a test that an individual roofer has to pass. Its Master Craftsman page says a roofer earns that credential by passing the Master Craftsman Roofing Contractor test after studying the company’s Shingle Applicator’s Manual. The same page says Master Craftsman is required before a company can join ShingleMaster, ShingleMaster PRO or ShingleMaster PREMIER.
What a badge lets the roofer register
The badge earns its keep when the contract names a warranty. GAF’s Golden Pledge, with 25 years of workmanship coverage, is limited to Master Elite contractors, while Certified roofers can offer System Plus, according to Home Team. Owens Corning’s Platinum Protection excludes faulty installation by anyone other than a Platinum Preferred contractor. Home Team also points out that a roofer with no GAF credential can still buy and install GAF shingles. The same shingle can go on your house with the enhanced coverage or without it.
The full comparison of each tier’s material and labor terms is in the asphalt shingle roof guide, and the roof warranty guide covers registration, transfers at sale and the common reasons claims get denied.
A manufacturer badge is not a county license
None of these programs gives anyone permission to work on your house. In Nassau and in Suffolk, home improvement contractors are licensed by the county, and that record is separate from anything GAF, Owens Corning or CertainTeed keeps. A manufacturer program is a sales and warranty relationship between the shingle maker and the roofer. The county license is the one tied to your rights as a homeowner.
Those rights are spelled out on our county pages. The Nassau license guide covers the county’s restitution fund, which can pay a homeowner who wins a judgment against a licensed contractor and does not help with unlicensed ones. The Suffolk license guide covers the county lookup, which shows complaints and violations as well as whether a license exists. Pick the one that matches the job address, then hold the number on the contract up against the county record. Our contractor checks page explains how the license line on each directory card is verified, and why a card shows no number when the match is uncertain.
Confirming a badge before you sign
Home Team says you can check a contractor’s GAF certification on GAF’s website by entering the business name. Search the exact company name on the contract. A sister company or a former partner may be the one holding the badge. For an Owens Corning or CertainTeed claim, ask the roofer which tier it holds today and look the company up on that manufacturer’s own site instead of trusting a logo on a flyer. Then ask the roofer two questions in writing: which warranty will you register on this job, and will you send me the registration confirmation? Keep that confirmation with the contract and the county license number.
