The Building Department page states that "The City of Ladue has adopted the following codes", listing the "2021 International Residential Code for One and Two Family Dwellings" with the other 2021 International Codes, and refers readers to the Code of Ordinances for the municipal amendments. The adopting section and the amendment list were not read, so this listing does not state whether they change Chapter 9, Roof Assemblies.

The Building Department's published answers state: "Roof repair or exterior repair from minor storm damage does not require a permit." They add that remodels of the exterior require a building permit, and that owners unsure whether a permit is needed should call the Building Department at 314-997-6308.
