NH Roofer Retains GAF Master Elite and Carlisle EPDM Status After 48 Years

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 credentials. The firm's 48 years of uninterrupted industry experience and multi-system roofing capabilities are highlighted at a time when commercial building owners in Southern New Hampshire, Northeast Massachusetts, and Southern Maine face complex roofing decisions.

Merrimack Valley Roofing and Gutters has operated as a commercial roofing contractor since 1976, building technical qualifications through consistent field performance. The firm holds GAF Master Elite status, a designation extended to fewer than two percent of U.S. roofing contractors, according to GAF. Alongside that, it maintains active Carlisle Sure-Seal EPDM certification, qualifying the company to install and warranty Carlisle's rubber roofing membrane systems. The company also holds a BBB A+ accreditation.

The firm installs EPDM, TPO, metal, and slate roofing systems, addressing varied commercial building types. TPO roofing systems have become a commonly specified choice for commercial flat roofs due to heat-reflective properties and weldable seam construction. Metal and slate systems extend the company's reach to historic structures and high-end developments.

Serving Southern New Hampshire, Northeast Massachusetts, and Southern Maine, the company operates from Sandown, supporting timely response across its service geography. The combination of manufacturer certifications and nearly five decades of field experience provides a documented track record for project stakeholders.
