Colorado CWRC Class A roof-assembly path

The 2025 Colorado Wildfire Resiliency Code specifies a Class A roof covering or assembly tested to ASTM E108 or UL 790 for Class 1 and inherited Class 2 hardening.

This record matches a documented tested roof assembly. The mapped fire-intensity class, covering and deck configuration, profile-space treatment, and local adopting ordinance remain checks.
