Commercial Roof Inspections in Phoenix

Documented roof walk, moisture-core pull, drain audit, and cool-roof reflectivity verification - written report delivered within three business days. Our office is downtown, and our project managers carry active inspection routes across the Phoenix metro.

Most commercial roof inspections in Phoenix are performed reactively - after a leak appears during monsoon season, after an insurance adjuster requests documentation, or when a building sale requires a property condition report. By that point, the insulation saturation that formed in August has already been compounding for months under a surface that looks dry. We inspect proactively and with a consistent method so that the data captured drives capital decisions rather than emergency responses.

Phoenix's climate creates inspection conditions that are genuinely different from most U.S. markets. The monsoon window (July 15 through September 30) is the primary moisture-intrusion event: haboob-deposited debris blocks drains, concentrated rainfall ponding works under perimeter flashings and around equipment curbs, and the insulation saturates while the surface dehydrates within 72 hours. By October, the roof looks dry on a visual walk. Moisture cores pulled at suspected intrusion points tell the actual story.

Every inspection we conduct includes a photo log keyed to a roof zone diagram, written notation of every observation, and a summary that distinguishes current condition from emerging risk. The deliverable is a report a

Membrane condition: We walk every accessible area of the roof surface, documenting open seams, blisters, surface erosion, ponding patterns, and membrane oxidation. On TPO systems, we look for seam weld failure - split welds, probe-weld delamination, and edge-lap voids - that are the primary water-intrusion path on mechanically attached and fully adhered single-ply in Phoenix's thermal cycling environment. On modified bitumen, we document granule loss, alligatoring, and bleed-out at seam edges. On EPDM, we look for shrinkage-induced flashing pulls at parapets and equipment curbs.

Moisture cores: On any roof where we observe ponding patterns, soft spots underfoot, or visual evidence of prior intrusion events, we pull 4-to-6-inch cores with a hole saw in 5 to 10 representative locations. Cores are inspected in the field and logged with GPS coordinates and photos. Wet insulation requires documented quantity and location before any recover-versus-replace recommendation can be supported. We patch every core location with compatible material on the same visit.

Drain and slope audit: We clear and inspect every drain on the roof - Phoenix drains accumulate haboob silica and monsoon debris between service visits, and a partially blocked drain is the root cause of more Phoenix insulation saturation events than any other single factor. We document drain capacity, debris load, drain-edge flashing condition, and any ponding pattern that extends more than 48 hours after a standard rainfall event.
