CentiMark is one of the largest commercial roofing contractors in North America. If you are a homeowner in Winston-Salem, Greensboro, High Point, Kernersville, Clemmons, Rural Hall, King, or anywhere else in the NC Triad researching roofing companies, this article explains what CentiMark actually does, where it fits in the market, and why a locally certified residential specialist is usually the right match for a home.
CentiMark was founded in 1968 by Edward B. Dunlap and is headquartered in Canonsburg, Pennsylvania. The company built its reputation in the commercial and industrial roofing sector, and today operates more than 100 office locations with more than 650 roofing crews across the United States and Canada. Its Canadian subsidiary operates as CentiMark LTD, and its flooring division, QuestMark, was established in 2006.
The company’s primary market is large commercial and industrial buildings. Its core services include flat and low-slope roof installation, roof repair, emergency response, preventative maintenance programs, and portfolio management for clients who own or manage multiple properties.
The roof systems CentiMark installs include:
These are almost entirely commercial and industrial products. CentiMark’s profile, its crew structure, and its warranty products are all designed around building owners and facilities managers, not residential homeowners.
CentiMark’s Single Source Warranty is cited by nearly every source that covers the company, but the explanation usually stops at “covers both workmanship and materials.” That description is accurate, but it skips the reasoning behind why it matters.
Most roofing projects involve two separate warranties: one from the manufacturer covering the material itself, and one from the contractor covering the quality of the installation. When a leak appears, the two warranty holders each have an incentive to blame the other. The manufacturer points to poor installation; the contractor points to a defective product. A building owner is caught between them, often bearing legal and logistical costs during the dispute.
The Single Source Warranty eliminates that gap by placing responsibility for both elements under one entity. If a problem develops, there is one phone call and one party responsible for the resolution. For a facilities manager overseeing a complex roof with dozens of penetrations, mechanical equipment curbs, and multiple subcontractors, that consolidation carries real value.
However, there are dimensions of any warranty that the summary phrase does not address, and a facilities manager should ask directly:
That last question matters because CentiMark holds GAF Chairman’s Circle status, the highest recognition tier in GAF’s contractor program. GAF recognition implies meaningful installation volume of GAF products. CentiMark also presents itself as a system-agnostic contractor offering TPO, EPDM, SPF, and metal. Those two facts are not automatically contradictory, but they do create a question worth asking: when CentiMark recommends a GAF product over a competing system, is that recommendation driven by performance data, or does the manufacturer relationship influence it?
The right approach for any buyer in that situation is to ask the contractor for a written comparison of the recommended system against at least one alternative, and to evaluate whether the reasoning is performance-based or relationship-based.

One detail that appears in historical accounts of CentiMark is the company’s pivot to EPDM in the late 1970s. At the time, the oil crisis degraded the quality of asphalt and increased its cost significantly, making the traditional built-up roofing systems less viable. CentiMark responded by shifting its focus to EPDM as a cost-effective and durable alternative.
Most accounts treat this as background history. It is actually a relevant decision-quality indicator.
A contractor that has historically changed its primary material recommendation when macroeconomic conditions shift the performance-to-cost ratio of an incumbent product is signaling something about how it approaches material selection generally. It is not dogmatically attached to one product. It responds to evidence. For a facilities manager evaluating CentiMark today, the relevant question is what the modern equivalent of that 1970s condition looks like. Supply chain disruptions, energy efficiency mandates, and changes in membrane manufacturing could all shift which system delivers the best long-term value. A contractor with a documented history of pivoting when evidence warrants it is worth evaluating differently than one with no such history.
CentiMark’s scale, warranty structure, and National Accounts Program are designed around commercial real estate and facilities management. They are not designed around a homeowner in roofing in Kernersville replacing a twenty-year-old shingle roof, or a family in Clemmons dealing with storm damage and an insurance claim.
Residential roofing requires a different kind of expertise and a different kind of accountability. The right contractor for a Triad homeowner:

With more than 60 combined years of roofing experience, CertainTeed PREMIER ShingleMaster certification, and more than 350 five-star Google reviews, Smithrock is built specifically for the kind of project CentiMark is not designed to handle.
The CertainTeed ShingleMaster certification is not a marketing badge. It reflects verified training standards and unlocks access to CertainTeed’s strongest warranty products, including coverage that protects homeowners against both material failure and installation defects.

For a homeowner comparing roofing contractors, the most useful questions are simple: Is this contractor certified by the manufacturer whose product they are installing? Do they have verifiable reviews from neighbors in my community? Can they explain their warranty in plain language? Those questions lead to the right answer faster than any national ranking. If you are still weighing your options, our article on choosing a roofing contractor in Winston-Salem walks through the key evaluation criteria in detail.
CentiMark is a well-regarded, large-scale commercial roofing contractor. Its Single Source Warranty addresses a real structural problem in commercial roofing. Its EPDM pivot history reflects sound institutional decision-making. Its GAF relationship is worth understanding before accepting a product recommendation.
None of that changes the fact that CentiMark’s entire business model is built around commercial facilities, not homes. If you own a home in the NC Triad and you are looking for a roofing contractor you can trust, the right fit is a locally certified specialist with a track record in your community. For homeowners who want to understand how to identify the right fit, the article on finding a professional roofing company near me outlines five practical trust steps worth reviewing. Smithrock Roofing is exactly that.
CentiMark’s core business is commercial roofing. While the company may take on some residential work in certain markets, its systems, warranties, and operational model are designed around large commercial facilities. Homeowners looking for a contractor who specializes in residential roofing will find a better fit with a locally certified company focused on that work.
CertainTeed’s ShingleMaster certification requires contractors to meet verified training and installation standards set by the manufacturer. It is not a self-reported badge. Contractors who hold this certification are eligible to offer CertainTeed’s strongest warranty products, which cover both material defects and installation errors. For a homeowner, that means meaningful protection backed by the manufacturer, not just the contractor’s word.
A Single Source Warranty is a commercial roofing warranty structure where one party, typically the roofing contractor, accepts responsibility for both the materials and the labor. It eliminates the common problem where material manufacturers and installation contractors each point to the other when something goes wrong. CentiMark offers this warranty structure, and it is one of the reasons the company is well regarded in the commercial sector.
The most reliable starting point is manufacturer certification. Find out whether the contractor is certified by the manufacturer whose products they plan to install on your home. From there, look for verifiable reviews from homeowners in your specific community, and ask the contractor to explain their warranty in plain language. A contractor who can answer those questions clearly is one worth trusting.
Homeowners in Winston-Salem and Greensboro deserve a roofing contractor who understands local weather patterns, knows the neighborhoods, and stands behind their work with manufacturer-backed warranties and a verifiable local reputation. Smithrock Roofing was built for exactly that, not as a national commercial operation, but as a CertainTeed PREMIER ShingleMaster-certified team with more than 60 combined years of experience and hundreds of five-star reviews from neighbors across the Triad.
