Commercial Roof Inspection Checklist for Property Managers
A commercial roof is a capital asset — and for a property manager, the inspection checklist is how you protect it. This is the walkthrough professionals use: what to check, in what order, and what to write down.

Before you go up
- Safety first: Never inspect alone. Use proper roof access, wear soft-soled shoes, and stay clear of edges and skylights. If the roof is wet, icy, or storm-damaged, postpone.
- Bring: This checklist, a camera, a tape measure, and the roof's history file (age, system type, past repairs).
- Know the system: TPO, EPDM, PVC, modified bitumen, or BUR — each has different failure modes. Review flat roof systems if you're unsure what you're walking on.
Membrane and surface
- Punctures, cuts, and abrasions — especially along service paths to HVAC units.
- Blisters and ridging — trapped moisture or air; note size and location.
- Alligatoring on BUR/mod-bit — crazed cracking signals an aging surface.
- Shrinkage or pulling at edges and penetrations (common on older EPDM).
- Open or fish-mouthed seams — the top leak source on single-ply roofs. See warning signs of membrane failure.
Flashing, penetrations, and edges
- Pipe boots and curbs: Cracked rubber boots, separated flashing at HVAC curbs and vent stacks.
- Wall and parapet flashing: Pulling away, open terminations, deteriorated sealant.
- Edge metal and copings: Loose, missing fasteners, wind-lifted sections — edge failures cascade fast in Colorado wind events.
- Skylights and hatches: Gaskets, dome cracks, proper closure.

Drainage
- Drains and scuppers: Clear of debris? Strainers in place?
- Ponding water: Any water standing 48+ hours after rain — photograph and measure. See how ponding water affects flat roofs.
- Gutters and downspouts (where present): Secure, clear, discharging properly.
Interior and documentation
- Below-deck: Walk the top floor — water stains, active drips, daylight through the deck.
- Document everything: Date, weather, who inspected, photos of every deficiency. This log protects warranties and justifies budgets — see how to keep a roof maintenance record.
- Prioritize: Active leaks and open seams = immediate. Deteriorating flashing = this season. Cosmetic aging = monitor.

FAQs
Can a property manager inspect the roof, or do I need a roofer?
Routine visual inspections are fine for a trained manager. But get a professional roofer's inspection at least annually and after major storms — they'll catch what a walkthrough misses.
What voids a commercial roof warranty?
Common voids: unauthorized repairs, added penetrations without proper flashing, ponding water beyond limits, and lack of documented maintenance. Keep the log.
Should I inspect after every storm?
After significant hail or wind events, yes — a quick check for new damage protects both the roof and any insurance position.
