What is IRC (International Residential Code)?
Roofing Glossary · Codes & Ratings
Definition
The model building code developed by the International Code Council (ICC) that sets minimum standards for one- and two-family residential construction in the United States. Most states adopt the IRC as the basis for their state residential building code. Roofing chapters in the IRC specify requirements for materials, installation methods, ventilation, ice barrier (ice-and-water shield), and structural loading.
