FOR IMMEDIATE RELEASE
SANDOWN, N.H. – Merrimack Valley Roofing and Gutters LLC is continuing to build manufacturer training and product knowledge across multiple major roofing brands, including GAF, CertainTeed, Owens Corning, Carlisle, Elevate, TAMKO, and other roofing-system manufacturers.
Manufacturer training helps contractors understand product-specific installation requirements, warranty rules, roof-system components, and the details that can affect long-term performance. For homeowners, that training can lead to clearer recommendations and better comparisons between material options.
Recent documentation reviewed for the company includes a TAMKO Pro Gold certificate recognizing Merrimack Valley Roofing and Gutters LLC as a TAMKO Pro Gold Certified Roofing Contractor since June 8, 2026. The certificate lists Pro ID 180416 and notes that the certification is subject to annual recertification.
The company has also documented CertainTeed Roofing Education progress, including Barry James passing the Shingle Technology Test through the Shingle Quality Specialist Program on June 8, 2026, with a 92.5% score, later documenting a June 12, 2026 result of 38 out of 40, or 95%, completing the CertainTeed Master Craftsman Roofing Contractor – SAM 17th Edition result on June 8, 2026, with a score of 33 out of 35, or 94.3%, and earning the CertainTeed Modified Bitumen Master Craftsman Credential on June 9, 2026, with a score of 68 out of 84, or 81%. CertainTeed's test feedback noted that the related certificates or fulfillment packages would be mailed separately.
"The right roof depends on the home, the slope, the ventilation, the budget, and the weather exposure," said Barry James. "Knowing multiple manufacturers helps us explain the options instead of forcing every homeowner into the same product."
Merrimack Valley Roofing provides inspections, repair, replacement, gutter work, storm-damage documentation, and roof-system planning for homeowners and property owners in the Merrimack Valley, southern New Hampshire, and northeastern Massachusetts.
