How Often Should a Commercial Roof Be Inspected in Houston?

If you manage a commercial property in Houston, your roof takes more punishment than almost any other building component. Between hurricane season, hail, 100-degree summers, and UV exposure that never lets up, the question isn't whether your roof will deteriorate. It's how fast.

The short answer: twice a year minimum. Once in spring before storm season hits, and once in fall after the worst of it passes. If your building took a direct hit from a named storm or a serious hail event, you need an inspection within 48 hours regardless of schedule.

Here's what most property managers get wrong. They wait until a tenant calls about water stains on the ceiling. By that point, the membrane has been compromised for weeks or months. The water you see inside the building traveled laterally through the insulation before it found a path down. The actual failure point could be 30 feet from where the stain shows up. That's a much bigger repair than it needed to be.

A proper commercial roof inspection covers every membrane section, every seam, every flashing around pipes and HVAC curbs, all drainage points including scuppers and internal drains, parapet wall caps, and edge metal. The inspector should be documenting everything with photos and ranking findings by urgency: fix now, plan for within six months, or monitor.

One thing worth knowing: most manufacturer warranties require documented maintenance to stay valid. Skip inspections for two years and you might find out your 20-year NDL warranty doesn't cover the $40,000 repair you just discovered. The inspection costs a few hundred dollars. The warranty coverage it preserves is worth tens of thousands.

In Houston specifically, we see the most damage from ponding water after heavy rain events, UV degradation on exposed TPO and PVC membranes, and wind uplift on edge flashings. All three are catchable with regular inspections before they become emergencies.
