What is manufacturer certification?

Training, a track record and ongoing obligations. Trade press lists product training, past installs, fees, crew time and recertification. A column by a metal-roofing maker's representative adds that some programs run credit checks, and that project specifications requiring certification "limit the bidding pool," which it calls good or bad depending on your perspective.

What the homeowner usually sees is the warranty. Many programs tie their longest warranties to installation by a certified contractor, which is a real selling point if you can explain exactly what it covers. Read your program's current terms before you advertise a warranty length, because the maker's terms, not your sales sheet, decide what a customer can claim.

Usually not in your business name. Google's guidelines say that if you sell another brand's products or services, "use only the name of the business, excluding the name of the brand being sold." The exception is narrow: an "authorized and fully dedicated seller of the branded product or service" may use the brand name.

A roofing company that installs one maker's shingles among others isn't a fully dedicated seller, so adding that maker's name to your profile name breaks the rule. Google also says your name "should reflect your business's real-world name." Put the certification in your profile description, photos and website instead, where it informs without renaming you. Our Google Business Profile page covers the rest of the profile rules.

Roofing and HVAC, mostly. Our count of the sources ChatGPT linked about named contractors found manufacturer, certification or trade-body sources in 892 of 1,500 roofing answers and 411 of 1,500 HVAC answers, but only 64 of 1,500 plumbing and 27 of 1,500 electrical answers (what ChatGPT checks).

So the value of a manufacturer listing depends on your trade. A link shows what an answer pointed to, not why. For roofing and HVAC contractors, a current locator listing with your exact business name is one of the records an answer may find. For electricians, your state license record matters far more.

Say exactly what you hold, keep it current, and let customers check it. Name the program tier you actually have, link to your listing in the maker's locator, and take the badge down if your status lapses. A lapsed badge on your website or truck is a claim that's no longer true.

Three more habits help. Use the logo only as the program's terms allow. Don't imply the manufacturer recommends you over other certified contractors unless it does. And keep the business name in the locator identical to the one on your site and profile, so the records connect. In our view, badges that can be verified, like a license number or a Google Verified check, carry more weight than ones that can't.
