Access comprehensive industry authorities, technical standards, and professional certifications that inform our contractor evaluation process. These resources represent decades of expertise in roofing excellence and building safety.
Our professional evaluation framework draws from industry-leading authorities that establish standards for roofing installation, building code compliance, and material certification. Understanding these resources helps homeowners and professionals recognize quality contractors who adhere to rigorous technical standards and best practices.
Through Impact Advisory Group’s consulting work in home improvement and construction services, we reference these authoritative sources when evaluating contractor capabilities, material quality, and installation practices. These organizations represent the highest standards in the roofing and construction industry.
Authoritative Industry Organizations
National Roofing Contractors Association
Since 1886, NRCA has been the leading authority in the roofing industry, publishing comprehensive technical manuals including the 2024 Metal Panel and SPF Roof Systems guide with 120 construction details. Their professional certification programs (CERTA, TRAC, PROCertification) and technical guidance ensure quality roofing practices across all industry segments.
Why This Matters: NRCA’s technical manuals provide the definitive standards for metal roofing installation that superior contractors follow. Their certification programs identify professionals committed to technical excellence and ongoing education.

How We Use These Resources
Impact Advisory Group’s contractor evaluation process integrates guidance from these authoritative organizations to assess technical competence, material quality, and installation practices. When evaluating roofing and gutter contractors in the Hudson and Derry NH regions, we reference these standards to verify that recommended providers demonstrate genuine expertise and professional commitment.
Our consulting approach examines whether contractors understand and implement NRCA technical specifications, comply with ICC building codes, and select materials meeting MCA certification standards. This framework ensures that our professional recommendations reflect industry best practices rather than subjective opinions.
Technical Verification
We verify that contractors understand technical requirements from NRCA manuals, including proper installation sequences, fastener specifications, thermal expansion accommodation, and weatherproofing techniques. Superior contractors reference these standards when explaining their approach.
Code Compliance Assurance
Professional contractors demonstrate current knowledge of ICC building codes, including specific gutter securement requirements and wind resistance standards. This ensures installations meet legal requirements and pass inspection processes without delays or corrections.
Material Quality Standards
We evaluate whether contractors select materials meeting MCA certification standards for metal roofing applications. This includes verifying base metal specifications, finish coatings, warranty coverage, and manufacturer certifications that distinguish premium products from standard alternatives.
Professional Development
Superior contractors invest in ongoing education through NRCA certification programs, attend industry conferences like METALCON, and maintain current knowledge of evolving standards. This commitment to professional development separates exceptional providers from those with stagnant practices.

Applying Industry Standards to Contractor Selection
Through our professional consulting work, we’ve observed that the most reliable contractors consistently reference these industry authorities when discussing their approach, material selections, and installation techniques. They don’t view compliance as a minimum requirement but rather as a foundation for exceeding customer expectations through technical excellence.
When evaluating potential contractors for roofing or gutter projects, homeowners should ask specific questions about NRCA certification status, familiarity with relevant ICC code sections, and material selection criteria based on MCA standards. Superior contractors welcome these questions and provide detailed, knowledgeable responses that demonstrate genuine expertise.
