ABSTRACT:
A ventilated cap system for use on a ridge of a roof which includes an expandable utility cap to seal over a variably expanding metal roof. In one form a top cap may snap lock over the utility cap for slidable attachment thereto when exposed to deforming forces such as snow or ice. The top cap prevents deformation of the underlying utility cap. Roof panel clips permit uneven thermal expansion between metal panel members.
