Hail belt

Yes — a permit is required to replace a roof in Duluth, MN, issued by City of Duluth, Minnesota - Construction Services & Inspections. Duluth issues permits through its online ePlace system. The basic process (per the city's own "Basic Permit Process" page) runs: research zoning/setbacks and permit type, submit the application through ePlace, a Permit Coordinator checks completeness and routes it for review, a Plans Examiner reviews for code compliance, then an invoice is issued through ePlace; once paid, the Permit Coordinator issues the permit with stamped plans and inspection cards, and inspections are scheduled as work proceeds by calling the assigned inspector. Starting work before the permit is issued doubles the permit fee and may trigger enforcement. Duluth, Minnesota sits in one of the country's most hail-prone regions.

Roofing permits & building code in Duluth

Roofing permit and contractor-licensing rules in Duluth are set locally by City of Duluth, Minnesota - Construction Services & Inspections. Minnesota requires a state Residential Roofer (RR) license from the Department of Labor and Industry to contract residential roofing work — roofing is expressly excluded from the single-special-skill exemption other trades can use, and the only relief is an affirmative Certificate of Exemption for small operators — and the Minnesota State Building Code applies statewide, so a city cannot adopt different roofing-code provisions, only its own permit administration and fees — always confirm the current requirements with the authority before starting work.

Photos of ice/water barrier and/or underlayment may be taken but are not required to be posted for the final inspection." Elsewhere, the same handout notes that for new construction "Roof sheathing and roofing may be installed before the framing inspection." Inspections generally must be requested a minimum of 24 hours (one business day) in advance by calling the inspector listed on the issued permit; inspectors are reachable 7am-3pm, Monday-Friday, per the city's "Inspection Information" page.
