Confirm the authority for the address. A state label or an IRC section by itself does not establish the requirement for a particular roof. Check the adopted edition, amendments, effective date, permit scope, and local building official’s interpretation. Collected handouts retain their issuer’s wording and may be superseded.
Collected handouts are government-issued references selected from the ClaimXperts document collection. Newer official sources replace outdated adoption sheets where available. External sources maintain their own access rules and may require an account.
Make the reference useful
Connect the requirement to the work.
Use these prompts to build a job-specific code file.
Decking & substrate
Photograph the deck, measure board width and gaps, and identify deterioration. Match the proposed product’s current installation instructions to the substrate. Explain which condition requires the proposed repair or overlay.
Drip edge, flashing & crickets
Identify the edge or penetration location, dimensions, and existing condition. Read the adopted flashing provisions and state modifications, then pair them with the installation detail for the actual roofing product.
Underlayment & ice barriers
Record roof slope and location, then verify the applicable wind criteria, ice-barrier trigger, product type, and approved installation method. A rule tied to a coastal wind region or local ice conditions should not be applied to every roof in the state.
Ventilation
Record attic area, existing intake and exhaust, and each product’s net free ventilation area. Check the adopted code’s ventilation ratio and all conditions for any permitted exception before selecting a calculation.
Wind, impact & fire ratings
Keep the property’s design criteria and the proposed product classification with the file. Wind resistance, impact resistance, and fire classification are different ratings; use the required test or classification for each.
Roof repair, replacement & recovery
Document existing roof layers, affected area, deck condition, and the proposed work. Verify local repair thresholds, recover restrictions, and inspection stages before relying on a full-roof or tear-off requirement.
