Founded in 1976, This NH Roofing Firm Carries GAF Master Elite and Carlisle Sure-Seal Credentials
Sandown, United States – June 13, 2026 / Merrimack Valley Roofing /
Merrimack Valley Roofing and Gutters, a Sandown, New Hampshire-based roofing contractor founded in 1976, has announced the continuation of its GAF Master Elite status and Carlisle Sure-Seal EPDM certification as active, current credentials — reinforcing the firm’s standing as a qualified resource for commercial property managers, builders, and developers across the region. The announcement draws attention to the company’s 48 years of uninterrupted industry experience and its multi-system roofing capabilities at a time when commercial building owners in Southern New Hampshire, Northeast Massachusetts, and Southern Maine are navigating complex roofing decisions.
Credentials Built Over Decades of Commercial Work
Merrimack Valley Roofing and Gutters has operated as a commercial roofing contractor since 1976, building its technical qualifications through consistent field performance rather than short-term credentialing efforts. The firm currently holds GAF Master Elite status, a designation that GAF, one of North America’s largest roofing manufacturers, extends only to contractors who meet specific training, insurance, and quality standards. Fewer than two percent of roofing contractors in the United States qualify for this status at any given time, according to GAF’s published criteria.
Alongside that designation, Merrimack Valley Roofing and Gutters maintains active Carlisle Sure-Seal EPDM certification, which qualifies the company to install and warranty Carlisle’s rubber roofing membrane systems on commercial structures. As a certified EPDM roofing contractor, the firm is positioned to deliver manufacturer-backed installation work that meets the documentation and workmanship requirements commercial property owners and developers frequently require for long-term asset protection.
The company also holds a BBB A+ accreditation, reflecting its record of client service and business conduct over its operating history.
Commercial Roofing Systems Across Multiple Product Lines
Merrimack Valley Roofing and Gutters offers a range of roofing systems designed to address varied commercial building types and owner requirements. The firm installs EPDM, TPO, metal, and slate roofing systems, giving commercial clients access to both low-slope membrane solutions and steep-slope applications under a single contractor relationship.
TPO roofing systems have become a commonly specified choice for commercial flat and low-slope roofs due to their heat-reflective properties and weldable seam construction. Merrimack Valley Roofing and Gutters brings that same level of technical competency to TPO work, applying the installation standards expected by building owners and project managers overseeing new construction and re-roofing scopes alike.
Metal and slate systems round out the company’s commercial offerings, extending its reach to historic structures, high-end developments, and buildings where long-term durability and material character are primary considerations.
Service Area Covers Key Commercial Markets in the Northeast
The firm serves commercial property owners, general contractors, builders, and developers operating across Southern New Hampshire, Northeast Massachusetts, and Southern Maine. This three-state footprint positions Merrimack Valley Roofing and Gutters to support regional development activity and ongoing maintenance programs in markets that include both established commercial corridors and growing suburban and mixed-use projects.
As a provider of commercial roofing in New Hampshire with a physical presence in Sandown, the company operates from a central location that supports timely response across its service geography. The combination of manufacturer certifications and field experience spanning nearly five decades represents a documented track record that project stakeholders can evaluate against the requirements of their specific building programs.
