## Openings across the existing roof

The assessment found defects in the open membrane field and at parapet walls, masonry junctions, penetrations and raised corners. Earlier patches and overlapping repair materials added to the detail work.

## Patching 22 locations

The affected areas were examined, cleaned and temporarily patched. Repairs followed the roof’s changing geometry, including locations where the membrane turns up a wall or meets an existing flashing.

## Maintenance planning

The temporary work addressed the identified defects while retaining the existing roof. The repair locations give the facility team a starting point for follow-up inspections and longer-term maintenance decisions.
