Some roofs have separate drainage provisions whose purpose is not obvious from a casual view. Their intended function should be understood before they are altered, covered, or removed. Appearance changes can affect building systems.
What to do next
Ask the responsible professional to identify the role of each outlet and the applicable design. Keep maintenance staff informed about which openings must remain clear. Do not authorize cosmetic modifications that interfere with a drainage component whose function has not been established.
