How Often Should a Commercial Roof Be Inspected?

A commercial roof in Dallas–Fort Worth should be inspected at least twice a year — once in spring and once in fall — plus after every significant hail or wind event. North Texas averages around 14 hail days a year, more than triple the national rate, so post-storm inspections aren't optional here. Most manufacturer warranties also require documented annual inspections, and skipping them can void your coverage.

Why twice a year, plus after storms

Spring inspections catch damage from winter and early storm season; fall inspections prepare the roof for winter and clear summer debris. But in DFW the real driver is hail and wind — a single storm can bruise or split a membrane and open seams that leak weeks later. A prompt post-storm inspection documents damage while it's fresh, which also matters for insurance.

What a commercial roof inspection covers

• Membrane condition — pitting, cracks, blistering and UV degradation
• Seams and laps — separation or open welds
• Flashings and penetrations — around HVAC curbs, drains, vents and skylights
• Drainage — ponding water, clogged drains and scuppers
• Interior signs — ceiling stains and moisture in the top floor

Inspections protect your warranty

Manufacturer NDL warranties typically require documented maintenance and inspections; a lapse can jeopardize a claim years later. Regular inspections also feed a proactive plan — see how commercial roof warranties work and the signs a roof needs replacement.
