Merrimack Valley Roofing and Gutters, a Sandown, New Hampshire-based roofing contractor established in 1976, has announced the continuation of its GAF Master Elite status and Carlisle Sure-Seal EPDM certification. These active credentials reinforce the firm's standing as a qualified resource for commercial property managers, builders, and developers across the region, drawing attention to its 48 years of uninterrupted industry experience and multi-system roofing capabilities.
The announcement comes at a time when commercial building owners in Southern New Hampshire, Northeast Massachusetts, and Southern Maine face complex roofing decisions. As a contractor with nearly five decades in the field, Merrimack Valley Roofing and Gutters holds GAF Master Elite status, a designation that GAF, one of North America's largest roofing manufacturers, extends to fewer than two percent of roofing contractors in the United States. This status requires meeting specific training, insurance, and quality standards, ensuring that clients receive manufacturer-backed installation work.
In addition to the GAF credential, the firm maintains active Carlisle Sure-Seal EPDM certification, qualifying it to install and warranty Carlisle's rubber roofing membrane systems on commercial structures. This certification positions the company to deliver 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.
Merrimack Valley Roofing and Gutters offers a range of roofing systems, including EPDM, TPO, metal, and slate. TPO roofing systems, known for their heat-reflective properties and weldable seam construction, have become a common choice for commercial flat and low-slope roofs. The firm applies rigorous installation standards to TPO work, serving clients overseeing new construction and re-roofing projects. Metal and slate systems extend its reach to historic structures, high-end developments, and buildings where durability and material character are primary considerations.
The firm serves commercial property owners, general contractors, builders, and developers across Southern New Hampshire, Northeast Massachusetts, and Southern Maine. This three-state footprint supports regional development activity and ongoing maintenance programs in established commercial corridors and growing suburban and mixed-use projects. As a provider of commercial roofing in New Hampshire, the company operates from a central location in Sandown, enabling timely response across its service area.
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. For commercial clients facing complex roofing decisions, the firm's credentials and longevity may offer reassurance that their roofing investments are backed by proven expertise and manufacturer support.
