RoofAuthority.org - National Roofing Reference Partner
The National Roofing Reference Network spans 26 state and specialty member sites organized under a single national hub, covering roofing licensing requirements, climate-specific installation standards, permitting frameworks, and contractor qualification criteria across the United States. This page describes the structure of that network, the scope of each member resource, and the regulatory landscape that governs roofing work at the state level. Navigating roofing services, codes, and contractor standards requires jurisdiction-specific knowledge — a uniform national summary is insufficient for decisions that vary as significantly as Florida's hurricane strapping requirements differ from Alaska's snow load calculations.
Definition and scope
The National Roofing Reference Network is a hub-and-spoke reference system connecting a national authority site to 26 state-level and specialty member sites. Each member site documents the roofing regulatory environment, contractor licensing structure, permitting requirements, and climate-driven installation standards for its respective jurisdiction.
Roofing as a regulated trade falls under a patchwork of state contractor licensing boards, local building departments, and model building codes — primarily the International Building Code (IBC) and International Residential Code (IRC) as published by the International Code Council (ICC), adopted in whole or in part by most US states. The Occupational Safety and Health Administration (OSHA) sets federal safety standards for roofing workers under 29 CFR Part 1926, Subpart Q, which governs fall protection for workers on surfaces 6 feet or more above a lower level.
The for this network provides entry-level orientation to the full member directory and site structure.
Roofing system types addressed across the network include:
- Steep-slope systems — asphalt shingles, wood shakes, clay and concrete tile, slate, and metal panels installed at pitches of 3:12 or greater
- Low-slope systems — built-up roofing (BUR), modified bitumen, thermoplastic polyolefin (TPO), ethylene propylene diene monomer (EPDM), and spray polyurethane foam (SPF)
- Metal roofing — standing seam, exposed fastener, and structural metal panel systems applicable across slope categories
- Green and specialty systems — vegetative roofs, photovoltaic-integrated assemblies, and cool-roof configurations subject to ENERGY STAR and Title 24 performance requirements in states like California
The distinction between steep-slope and low-slope systems is not cosmetic — each category triggers different code provisions, installer certification pathways, and material performance standards.
How it works
Each member site in the network functions as a jurisdiction-specific reference for contractors, property owners, researchers, and building professionals operating in that state. Sites document contractor licensing boards, required insurance thresholds, examination requirements, continuing education mandates, and the specific edition of the building code adopted by that state.
The section of this network maps how federal, state, and local authority is distributed across roofing work — from OSHA's worker safety jurisdiction to state licensing board authority over contractor qualification.
Florida Roof Authority covers one of the most demanding roofing regulatory environments in the country, including the Florida Building Code's hurricane provisions, which require wind uplift resistance ratings developed after Hurricane Andrew in 1992 caused an estimated $27 billion in insured losses (NOAA National Centers for Environmental Information).
California Roof Authority documents the state's Title 24 cool-roof mandates, CSLB (Contractors State License Board) Class C-39 roofing contractor requirements, and wildland-urban interface (WUI) fire-rated assembly requirements that apply to approximately 2 million properties in high-hazard fire zones (California Department of Forestry and Fire Protection, FRAP).
Texas Roof Authority addresses the notable absence of a statewide roofing contractor license in Texas, where licensing authority rests entirely with municipalities, and documents hail damage claim protocols relevant to the state's position as the highest-volume roofing insurance claim state by frequency.
New York Roof Authority covers the New York City Department of Buildings permitting framework, the NYC Energy Conservation Code's roofing provisions, and the state-level contractor registration requirements that differ by borough and county.
Georgia Roof Authority references the Georgia State Licensing Board for Residential and General Contractors and documents the distinction between licensed and subcontracted work on commercial versus residential roofing projects.
North Carolina Roof Authority addresses the North Carolina Licensing Board for General Contractors, the wind-driven rain provisions of the NC Residential Code applicable to coastal zones, and insurance-related disclosure requirements for storm damage contractors.
Pennsylvania Roof Authority covers the Home Improvement Consumer Protection Act (HICPA), which requires contractor registration with the Pennsylvania Attorney General's office for residential projects exceeding $500, and the state's adoption status of IBC/IRC editions.
Ohio Roof Authority documents Ohio's contractor licensing structure, which is administered at the municipal level in cities including Columbus, Cleveland, and Cincinnati, and addresses Ohio Building Code (OBC) provisions governing roofing assemblies on commercial structures.
Common scenarios
Roofing reference needs cluster around identifiable situations:
- Post-storm damage assessment — property owners and adjusters in states like Texas, Florida, and Colorado seek code-minimum repair standards and licensed contractor verification procedures
- Permit application — contractors and owners need jurisdiction-specific information on which roofing projects require a permit (most jurisdictions require permits for full replacements and new construction; repair thresholds vary)
- Contractor verification — licensing board lookup procedures, bond requirements, and insurance minimums differ by state
- Code compliance — architects and builders need the specific IBC or IRC edition in force in a jurisdiction, along with any local amendments
Illinois Roof Authority covers roofing contractor licensing administered through the Illinois Department of Financial and Professional Regulation and the requirements that apply to Cook County and the City of Chicago, which maintains its own building code independent of the statewide IRC adoption.
Washington Roof Authority documents the Washington State Department of Labor & Industries' contractor registration system and the state's energy code provisions requiring minimum R-49 attic insulation in Climate Zone 5, the zone covering most of western Washington (Washington State Energy Code, WAC 51-11C).
Michigan Roof Authority addresses Michigan's Bureau of Construction Codes, contractor licensing through the Department of Licensing and Regulatory Affairs (LARA), and ice-dam prevention requirements driven by the state's position in Climate Zone 5-6 under ASHRAE 90.1.
Tennessee Roof Authority covers the Tennessee Board for Licensing Contractors, the financial threshold requiring licensure (projects over $25,000 require a state contractor license), and the state's adoption of the International Residential Code with Tennessee-specific amendments.
Decision boundaries
The network's member sites serve different decision contexts depending on the user's role and geography. Selecting the appropriate state resource is the first decision boundary; within each state resource, the relevant distinction is between residential and commercial roofing work, which often triggers separate licensing tracks, code chapters, and permitting workflows.
Arizona Roof Authority is the reference for the ROC (Registrar of Contractors) licensing structure in Arizona, which classifies roofing under CR-8 (residential) and C-17 (commercial) license classifications, and for the reflective roofing requirements in the Phoenix metro area under the Maricopa County heat island mitigation framework.
Colorado Roof Authority documents the roofing-specific provisions of Colorado's Consumer Protection Act as they apply to storm-chaser contractor solicitation, and addresses the hail-frequency data that makes Colorado the third-highest state for hail damage claims in the US (Insurance Information Institute, III.org).
Maryland Roof Authority addresses the Maryland Home Improvement Commission (MHIC) licensing requirements, mandatory contractor bonding of $20,000 per MHIC statutory requirements (Md. Code, Bus. Reg. § 8-301), and the state's adoption of the 2021 IRC.
Massachusetts Roof Authority covers the Massachusetts State Board of Building Regulations and Standards, the Construction Supervisor License (CSL) requirement for residential roofing, and the state's stringent stretch energy code provisions that impose higher insulation values than base IRC requirements.
Virginia Roof Authority references the Virginia Department of Professional and Occupational Regulation (DPOR), Class A/B/C contractor licensing tiers, and the Virginia Uniform Statewide Building Code (USBC) that governs both residential and commercial roofing assemblies.
Roofing Standards Reference provides cross-jurisdictional documentation of material performance standards, including ASTM International standards for shingle testing (ASTM D3161, D7158) and FM Global and UL listings relevant to commercial low-slope systems.
