ICC-ES AC75

Full Name

ICC-ES AC75 – Acceptance Criteria for Membrane Roof-covering Systems

Scope

ICC-ES AC75 outlines the requirements and evaluation methods for membrane roof-covering systems used in low-slope and steep-slope applications. The scope includes:
  • Materials: it specifies the acceptable materials for membrane roof coverings, including thermoplastic, thermoset, and modified bitumen membranes, as well as their reinforcement and surfacing materials.
  • Performance requirements: it defines the performance criteria for membrane roof coverings, such as resistance to weathering, wind uplift, fire, hail, and puncture. It also addresses requirements for watertightness, dimensional stability, and compatibility with other roofing components.
  • Testing procedures: it details the standardized testing methods for evaluating the performance of membrane roof coverings under various conditions, including laboratory and field tests.
  • Installation requirements: it provides guidelines for the proper installation of membrane roof coverings to ensure their long-term performance and durability.
  • Evaluation and certification: it outlines the process for evaluating and certifying membrane roof-covering systems to ensure they meet the acceptance criteria.
ICC-ES AC75 is crucial for manufacturers to demonstrate that their membrane roof-covering systems comply with the required safety and performance standards. It also provides valuable information to designers, builders, and building owners for selecting and installing suitable roof coverings for their projects.
