Roofing Glossary · Codes & Ratings
Definition
A geographic classification system that defines the design wind speeds for which structures in an area must be built. The International Building Code recognizes four wind zones (I-IV), with Zone IV covering the highest wind speeds in coastal and hurricane-prone regions. Roofing materials, fastener patterns, and installation methods must be specified for the applicable wind zone. ASCE 7 design wind maps guide code requirements.
