New Hampshire Roofing Firm Marks 48 Years with GAF Master Elite and Carlisle EPDM Credentials

Merrimack Valley Roofing and Gutters, a Sandown, New Hampshire-based roofing contractor in operation since 1976, has reaffirmed its GAF Master Elite status and Carlisle Sure-Seal EPDM certification, highlighting nearly five decades of experience in the commercial roofing industry. The company serves commercial property managers, builders, and developers across Southern New Hampshire, Northeast Massachusetts, and Southern Maine, offering a range of roofing systems including EPDM, TPO, metal, and slate.

The GAF Master Elite designation is held by fewer than two percent of roofing contractors in the United States, according to GAF’s published criteria. To qualify, contractors must meet stringent training, insurance, and quality standards. Similarly, the Carlisle Sure-Seal EPDM certification allows the company to install and warranty Carlisle’s rubber roofing membrane systems, providing manufacturer-backed assurance for commercial clients. The firm also maintains an A+ accreditation with the Better Business Bureau.

With 48 years of uninterrupted industry experience, Merrimack Valley Roofing and Gutters positions itself as a resource for complex commercial roofing decisions. The company’s multi-system capabilities include TPO roofing systems, which are valued for their heat-reflective properties and weldable seam construction, as well as metal and slate roofing for historic or high-end developments. This breadth of offerings enables the firm to address both low-slope membrane solutions and steep-slope applications under a single contract.

The company’s service area covers key commercial markets in the Northeast, including established corridors and growing suburban and mixed-use projects. Operating from a central location at 496 Main Street in Sandown, the firm supports timely response across its three-state footprint. For property owners and developers evaluating roofing contractors, the combination of manufacturer certifications and long-term field experience provides a documented track record.

As a family-owned business, Merrimack Valley Roofing and Gutters has built its technical qualifications through consistent field performance rather than short-term credentialing. The company’s credentials, including GAF Master Elite status and Carlisle Sure-Seal EPDM certification, are active and current, reinforcing its standing as a qualified resource in the region.
