Commercial Roof Maintenance Checklist for DFW Property Managers

Why Quarterly Inspections Matter in DFW

Most commercial roof failures we see in DFW are preventable. Not because the materials failed — because nobody was catching the small stuff before it became big stuff. A blocked drain that creates ponding water for 90 days. A lifted flashing at an HVAC curb that lets moisture in slowly. Seam separation at a low-traffic corner that nobody notices until the deck below is saturated. We see this all the time on buildings in Las Colinas, Lewisville, and along I-30 in Arlington.

The math is simple: a 30-minute quarterly walkthrough costs you nothing and catches problems when they're a $200 repair. Skip the quarterly walks for two years, and that same problem becomes a $50,000 emergency.

The Quarterly Walk: What to Check

Every three months, do a full roof walk and check these items. Drains and scuppers — remove any debris, confirm water flows freely. Membrane surface around HVAC curbs — these are the highest-traffic areas and the most likely to develop splits or punctures. Visible seam separation anywhere on the field membrane. Flashing at walls, penetrations, and parapet caps — look for lifted edges, cracks, or rust. Parapet wall caps — check for popped seams or open joints. Caulk and sealant at penetrations. Roof access hatch seals. Gutter and downspout flow. Evidence of foot traffic damage (scuff marks, compression patterns near equipment).

After every rain, check for ponding water. Standing water that remains more than 48 hours after a storm is a problem — it accelerates membrane deterioration, adds structural load, and eventually finds a path through seams or penetrations. Chronic ponding means you have a drainage issue or structural deflection that needs to be corrected, not just drained.

After Every DFW Storm: The 48-Hour Check

DFW averages 2–4 significant hail events per year and multiple 50+ mph wind events. After any of those, get on the roof within 48 hours. Look for: membrane punctures or tears from hail impact, displaced flashing or edge metal, debris from blown vegetation or neighboring rooftops, HVAC equipment displacement, new ponding areas that didn't exist before the storm, gutter and downspout blockage from debris.

Document everything with photos. Time-stamped photos taken within 48 hours of a storm are the baseline for any insurance claim. If you wait two weeks to document and then file a claim, the adjuster has grounds to question whether the damage happened in this event or a prior one. Take the photos while the context is fresh.

The Annual Professional Inspection

Even with diligent quarterly self-inspections, you need one professional inspection per year with thermal imaging. Here's why: moisture trapped under a TPO or EPDM membrane is invisible to the naked eye. It doesn't show as a stain, doesn't cause an active leak yet, doesn't look like anything from the surface. But thermal imaging shows it clearly as temperature differentials — wet insulation holds heat differently than dry insulation, and that shows up on the scan.

Joel always says the best time to do a thermal scan is two to three hours after sunset in spring or fall — the roof has been heated all day, and the areas with trapped moisture cool down at a different rate than the dry areas. A good scan takes 20–30 minutes with a drone and gives you a precise map of where moisture intrusion has started before it causes structural damage.

JRH does these free for commercial properties in DFW. It's not a loss leader — we do it because it's the right way to serve property managers, and because when we find something, we get the repair work. But if we don't find anything, we tell you the roof looks good and walk away. No manufactured urgency.
