What can a roof edge reveal?
Inspect the edge as a connected assembly. The field membrane, termination bar or cleat, coping, fascia, and wall flashing each have to support a continuous water-control detail. Look for lifted metal, loose fasteners, open joints, cracked sealant, or a membrane that has pulled back from its termination. Photograph the condition from several points and note whether the same detail continues along adjacent roof areas.
A leak at the perimeter may follow the wall or deck before it reaches the interior. Compare the reported room location with parapet corners, expansion joints, roof transitions, and nearby drains. A ceiling stain below a storefront or office wall does not prove the wall flashing is the source; the roof inspection should follow the route and check each plausible entry point. Keep the roof finding separate from interior finish repair.
The commercial and regional-access context of the I-30 corridor can help an owner orient a service request, but it does not identify the building's construction. Record the actual roof system and edge assembly before specifying metal or membrane. If the parapet substrate is loose or damaged, identify that repair separately from replacement of the visible coping.
