When you search for a roofing contractor, you will see a lot of claims. Family owned. Years of experience. Five-star reviews. Most of those claims are hard to verify on their own. The CertainTeed Premier Installer credential is different. It is the highest certification a roofing company can earn from CertainTeed, one of North America’s most trusted roofing manufacturers. And Marios is the first and only company in Massachusetts and Rhode Island to hold it. Here is what that means for you and your home.

What Is the CertainTeed Premier Installer Credential?

CertainTeed created a tiered credential system so homeowners have a clear way to evaluate roofing companies. The tiers run from Master to Pro to Premier. Premier is the top level. It is the highest credential a roofing company can earn from CertainTeed, and only a small number of contractors across the country hold it.

The credential is not based on sales numbers or how much product a company buys. It is earned by meeting a strict set of requirements covering installation knowledge, crew training, business standards, and customer satisfaction. Once earned, it must be maintained through ongoing compliance. You can see how Marios stacks up on our industry certifications page.

You can learn more about the full requirements directly on the CertainTeed credential program page.

What Does It Take to Earn Premier Status?

The requirements to become a CertainTeed Premier Installer go well beyond what most homeowners would expect from a standard contractor license. Here is what a company must demonstrate.

Years in business. The company must have a verified operating history as a roofing contractor. New companies and storm-chasing operations cannot qualify.

Trained crew. A majority of the shingle installation crew, plus all supervisors, must hold active CertainTeed technical credentials. This includes passing hands-on training and knowledge assessments.

Business standards. The company owner must pass CertainTeed’s business responsibility exam, and the company must follow CertainTeed’s code of ethics covering customer service, installation quality, and legal compliance.

Insurance. Current general liability and workers’ compensation coverage is required, with proof provided. This protects homeowners if an accident happens on their property.

Customer satisfaction. A strong customer rating must be maintained. There is no buying your way through a bad track record.

These are verified standards, not self-reported claims. That is the whole point of the credential.

What Homeowners Get From Working With a Premier Installer

Choosing a CertainTeed Premier Installer is not just about the name. It has real, practical benefits for you as a homeowner.

Stronger warranty coverage. Only a CertainTeed Premier Installer can offer you CertainTeed’s highest warranty tier, the SureStart PLUS warranty. This covers both materials and labor without proration for an extended term, including tear-off and disposal costs if you ever need to file a claim. It is also transferable to a new owner within the first 15 years, which adds real value if you sell your home. A contractor without Premier status cannot offer this level of coverage, even if they use CertainTeed products. The warranty is tied to the installer, not just the shingles. If you are thinking about the cost of a new roof in Massachusetts, the warranty tier you receive is a big part of understanding the long-term value of what you are paying for.

You can review the full details of the SureStart PLUS coverage on the CertainTeed warranty page.

Installation to manufacturer standards. CertainTeed’s installation requirements go further than local building codes. A Premier Installer follows those standards because the credential depends on it. For Massachusetts and Rhode Island homeowners, that means correct ice and water shield coverage, proper ventilation, and flashing that holds up through New England winters. These details separate a roof that performs well for decades from one that starts showing problems in just a few years.

Accountability after the job is done. When you hire a contractor without a verified credential, your options if something goes wrong are limited to whatever is in your contract. A CertainTeed Premier Installer works inside a framework that CertainTeed actively enforces. If the standards are not met, the credential is pulled. That accountability structure changes the incentives in your favor. Learn more about our roofing services and what we include in every project.

How to Choose Between Certified Roofing Contractors

When you are figuring out how to choose a roofing contractor in Massachusetts or Rhode Island, the certification tier is a smart first filter. But two companies can both hold Premier status and still differ in ways that matter.

After confirming the credential, ask these questions. How long has the contractor been working in your specific area? Local knowledge of permit requirements, roof configurations, and regional weather matters here. Can they provide references from completed projects near you? Is the estimate written out in detail, including product lines, warranty tiers, and a full scope of work?

The NRCA recommends getting at least two to three estimates before committing, and making sure each estimate covers the same scope so you are comparing apples to apples. A significantly lower price from a contractor with equivalent credentials is worth looking into before signing. For a deeper look at the full vetting process, read our guide on how to pick the right roofing contractor.

If a contractor does not list any manufacturer credential, ask directly. Ask what warranty they can offer on materials and labor. Ask whether they pull permits. A contractor who cannot provide current insurance, does not pull permits, or cannot offer an extended manufacturer warranty is carrying more risk for you than one who can.

Why Marios Holds This Certification

Marios earned the CertainTeed Premier Installer credential because the installation standard it requires reflects the way we have worked since 2005. We do not cut corners on ventilation, ice and water shield coverage, or flashing details, because those are the things that determine whether a roof actually holds up through a New England winter.

We also hold the CertainTeed SidingMaster Premier credential for siding, making Marios the first and only company in Massachusetts and Rhode Island to hold both Premier certifications across roofing and siding. Every homeowner we work with gets the strongest warranty coverage CertainTeed offers, installed by a crew that meets the full credential requirements to deliver it.
