Canonical: https://cmac-new-concept.vercel.app/about Last updated: 2026-08-24 Veteran-owned. Five states. One standard. ## What to know. CMAC Roofing and Sheet Metal LLC is a veteran-owned and operated construction and remodeling company founded by Christian Viveiros. What started as a roofing company has grown into a full exterior and restoration contractor working across five states, but the operating principle has not changed: earn the customer’s trust, use only quality materials, and deliver workmanship that holds up after everyone has gone home. The company motto is “Integrity Truly Matters.” In this trade that is not a slogan you get to say for free. Roofing and storm restoration attract operators who show up after a hailstorm, oversell a claim, cut the installation, and are gone before the first leak. CMAC is built the opposite way — around local offices with local crews and named estimators who are still reachable in three years. ## What we do CMAC runs five divisions: roofing, gutters, garage doors, restoration, and exteriors. That range exists because the exterior of a building is one system. Hail that damages a roof usually damages the gutters, the garage door, the siding, and the window screens in the same event, and a homeowner should not have to project-manage four contractors and four insurance line items to put it right. - Roofing — repairs, full replacement, new construction, custom homes, specialty tile and slate systems, commercial low-slope systems, and multi-family portfolios - Gutters — seamless installation, repairs, guards, maintenance programs, and high-volume commercial drainage - Garage doors — residential and commercial installation, openers, and repair, backed by five major manufacturers - Restoration — 24/7 water mitigation, fire and smoke damage, resurfacing, floor care and odor control, and trauma and biohazard cleanup - Exteriors — siding, replacement windows, decks, and exterior painting ## Certifications and standing CMAC is a GAF Master Elite® certified contractor — a status held by a small percentage of roofing contractors in North America, which requires documented licensing, insurance, and a sustained record of quality installations. CMAC has also been named a GAF President’s Club award winner, holds an A+ rating with the Better Business Bureau, and is a member of the National Roofing Contractors Association. Our GAF contractor ID is 1131347. On the multi-family side, CMAC is a member of the Apartment Association of Greater Dallas and the Fort Worth Apartment Association. ## Where we work CMAC serves Texas, Oklahoma, Arkansas, Tennessee, and Georgia. It publishes office addresses and local contact information for Dallas–Fort Worth, Houston, Austin, Oklahoma City, and Nashville. Arkansas and Georgia inquiries route through the regional line; CMAC does not publish a walk-in office in either state. ## Living Life Unlocked “Living Life Unlocked” is how CMAC describes what the work is actually for: creating opportunities, building lasting relationships, and delivering peace of mind through dependable service and quality workmanship. A roof is a large, disruptive, expensive purchase that most people make once or twice in their lives. Doing it right means the customer stops thinking about it — which is the whole point. ## Credentials and professional standing ## Contact a CMAC market - **Dallas–Fort Worth, TX** — CMAC is headquartered in Haslet and publishes this office as its Dallas–Fort Worth contact point.

CMAC Roofing and Sheet Metal LLC is a veteran-owned and operated construction and remodeling company founded by Christian Viveiros. We handle roofing, gutters, garage doors, restoration, and exterior work for residential, commercial, and multi-family properties. We are a GAF Master Elite® certified contractor and a GAF President’s Club award winner. ### What states does CMAC serve? Five: Texas, Oklahoma, Arkansas, Tennessee, and Georgia. CMAC publishes office addresses and local contact information for Dallas–Fort Worth (Haslet), Houston (Rosenberg), Austin (Georgetown), Oklahoma City, and Nashville. Arkansas and Georgia inquiries route through the regional line; no walk-in office is published in either state. ### What are CMAC’s core principles? Earn the customer’s trust, use only quality materials, and deliver exceptional workmanship. The company operates under the motto “Integrity Truly Matters,” and the practical version of that is simple: document what we find honestly, quote what the job actually requires, and stand behind the work after the crew leaves. ### What does GAF Master Elite® mean? GAF awards Master Elite® status to a small fraction of roofing contractors in North America. It requires proof of proper licensing, adequate insurance, and a sustained record of quality installations and customer satisfaction. Practically, it means CMAC can offer enhanced GAF system warranties that non-certified contractors cannot, and that GAF has independently vetted the company. CMAC is also a GAF President’s Club award winner. ### How much does a new roof cost? There is no honest answer to that question without seeing the roof. Price is driven by measured square footage, the pitch and complexity of the roof, how many layers have to come off, how much decking has turned out to be rotten, the material system you choose, and whether the work is going through an insurance claim or being paid out of pocket. That is why CMAC inspects and measures before quoting rather than publishing a per-square number that would be wrong for most homes. The inspection and the written estimate are both free. ### Do you charge for an inspection or an estimate? No. The inspection, the damage documentation including drone photography, and the written estimate are all free and carry no obligation. If the roof does not need work, we will tell you that. ### Do you offer financing? Financing options vary by market and by project. Ask your estimator during the inspection and they will walk you through what is currently available for your job. CMAC does not publish standing financing terms online because they change. ### Will CMAC work with my insurance company? CMAC can document visible damage, provide a contractor report, and attend the carrier’s inspection to explain the proposed repair scope. CMAC is a contractor, not a public adjuster or law firm, and does not interpret policy coverage or represent a policyholder in a coverage dispute. ## Start with a free inspection. Tell CMAC what is happening at the property. We will inspect the condition and put the recommended scope in writing.
