Louisiana Roofing Legislation, Codes, and Guidelines

State Statutes and Building Codes

In Louisiana, building codes are established at the state level to ensure consistent safety and construction standards. Roofing and re-roofing projects must comply with the versions of the International Building Code (IBC) and International Residential Code (IRC) adopted and promulgated by the Louisiana State Uniform Construction Code Council (LSUCCC). Specifically, for one- and two-family dwellings, roofing work must comply with Chapters 8 and 9 of the International Residential Code. For all other buildings, compliance with Chapter 15 of the International Building Code is required. Recent legislation, including Act 239 (effective August 1, 2025), mandates that all municipalities and parishes that issue construction permits must also issue permits for and conduct inspections of all roof construction and re-roofing projects in accordance with these state-adopted codes.

Primary State Agencies

The primary agency responsible for setting and maintaining these construction standards is the Louisiana State Uniform Construction Code Council (LSUCCC). Additionally, the Louisiana State Licensing Board for Contractors (LSLBC) oversees the licensing requirements for contractors. As of January 1, 2026, under Act 422, any person performing, bidding on, or advertising for residential roofing work on a residential structure with a project value of $7,500 or more must hold a specific Residential Roofing or Residential Construction license issued by the LSLBC.
