If you live in Illinois, you need to know the applicable building regulations before beginning home projects like roof repairs and replacements. These building codes tell you the proper procedures for getting permits and other acceptable practices to follow during your projects. Ensure you’re prepared for your next endeavor with these insights into the state’s regulations and building codes.

What Regulations Cover Illinois Building Projects?

Currently, Illinois has no statewide building codes, though it will require statewide codes beginning on January 1, 2025. Until then, those completing building projects in the state must look to their city, village or county codes for guidance. Some codes apply regardless of local regulations. These include:

  • International Residential Code
  • International Building Code
  • Illinois Energy Conservation Code
  • Illinois Plumbing Code
  • Illinois Accessibility Code
  • Fire prevention and safety rules

When local governments lack building codes, those completing projects must comply with the Illinois Residential Building Code Act.

Like other building regulations, roofing regulations in Illinois depend on local laws. Some regulations include protection against wind and fire to ensure contractors use materials and practices that keep your home safe from inclement weather and minimize fire hazards. Regulations can also cover details like the roofing materials contractors may use and the methods employed during installation.

Do You Need Permits and Licensing in Illinois?

Like building codes, permits depend on local regulations. Before starting a building or repair project, check with your local Building Department to learn your permitting requirements. Most significant changes to a home require permits, including things like roof replacements. Often, you must fill out a permit application and submit it with a permit fee and project schematics for approval. Permit costs vary, but roofing permits in Illinois are often cheaper than those for other building projects.

Illinois law also requires roofing contractors to hold licenses for the work they perform. They must have roofing licenses to do any roofing or waterproofing work.

What Types of Roofing Work Require Code Compliance?

Building codes may vary by the city, meaning you should research local building codes or work with an experienced contractor who knows the regulations. Illinois building codes for roof replacements and repairs often cover work like:

  • Truss work
  • Shingle layers
  • Sheathing
  • Decking
  • Flashing
  • Venting
  • Ice and water shields
  • Inspections

Building codes often require contractors to perform roofing tasks according to the manufacturer’s instructions. Codes may require that repairs or replacements are the same or better quality than the original work. Many local building codes in Illinois say houses cannot have more than two layers of shingles. Certain codes require that contractors install particular roof elements like flashing, ice and water shields, and vents in specific spots.
