For multifamily and commercial properties, the value of a roof inspection is the record it leaves. A documented history is what lets ownership compare immediate repair needs with capital planning.
Document by Roof Section, Not by Building
Large properties should be recorded section by section: membrane or shingle condition, drains and scuppers, penetrations, flashings, equipment curbs and previous repair areas. Recurring problems only become visible when the same areas are photographed over time.
Tie Leak Reports to Locations
Log resident and tenant leak reports by unit and date, then map them to roof areas. A leak that appears in one unit may originate at a transition or drainage condition some distance away.
What a Useful Report Contains
Affected areas, observed defects, recommended scope, known assumptions and photos. A roof inspection that answers “what, where, how urgent, and what happens if we wait” is a planning document, not just a service call.
