New equipment, access traffic, or an altered penetration can coincide with a leak, but timing alone does not establish cause. The useful question is what changed at the affected roof area and how its waterproofing was restored.
What to do next
Collect work orders and before-and-after photographs without assigning blame prematurely. Ask the roofer to document the current detail and material compatibility. Clarify who will coordinate any correction involving the equipment contractor, warranty provider, or building manager.
