Pre-monsoon checklist for commercial property managers in West Texas

El Paso and the Permian basin start getting hit by monsoon storms in the last week of June. The interior water claims that follow are almost always preventable. We see the same five line items show up in claim documentation every season. They are the ones property managers should be walking right now.

This is the spring walk-through we do on our own properties and on properties we manage for owners. It takes about 90 minutes for a single-story 30,000 square foot building. It is the cheapest insurance you can buy.

1. Roof drains, scuppers, and overflow scuppers

Walk the roof and find every drain, every scupper, and every overflow. Look down each one. The strainer should be clear of debris. The seal between the strainer and the drain bowl should be tight. The pipe below the drain should be free-flowing.

The number one monsoon claim on West Texas commercial buildings is interior water intrusion caused by ponding from a blocked drain. By the time water comes through the deck, you are looking at insulation replacement and tenant interruption, not just a roof patch.

If a building has internal drains that empty into a vertical leader inside the structure, also check the cleanout at the base of the stack. A drain that backs up at the cleanout because the lateral is blocked will push water back through the roof penetration.

2. Roof penetrations and flashings

Every penetration is a potential leak. HVAC curbs, exhaust fans, plumbing vents, gas vents, antenna mounts, lightning protection, anchor points, refrigerant line sets. Walk to each one and look at the flashing.

The common failures we see are sealant that has cracked or pulled away, lifted laps, bird-pecked or rodent-chewed flashings, and HVAC curbs where the unit has shifted slightly and broken the seal at one corner. None of these can be fixed in the rain. All of them are easy to fix in May.

3. Coping, parapet caps, and reglets

Walk the perimeter and look at the coping or parapet cap. The joints between coping sections should have intact sealant. The reglet where the roof membrane terminates at the parapet should be tight against the wall, with no visible gap.

Monsoon winds in El Paso routinely push 50 mph. A loose section of coping becomes a sail. Once one section lifts, the next sections rip off in sequence and the parapet itself starts taking water. This is a leading cause of total-loss roof claims in the Borderplex.

4. Site drainage and parking-lot grading

Walk the parking lot during or right after a rain if you can. Where does the water go? Properties built before 2005 in El Paso often have surface drainage routed straight at the building because the original grading has settled.

If water sheets toward the building, you have two options before monsoon: regrade the affected section, or add a swale or curb-cut diversion. The cost is meaningful in May. It is much more meaningful when it shows up as a tenant claim in August.

Pay particular attention to truck dock pits, sunken loading areas, and ramp-down service entrances. Any below-grade element collects water faster than the drainage system can move it. Verify the pump is working and the float switch is set correctly.

5. Storefront, doors, and threshold seals

Glass storefronts, automatic doors, and pedestrian doors with thresholds all have weather seals that dry out and crack in the El Paso sun. A failed door bottom sweep at a tenant entrance during a monsoon downpour pushes water across the floor and into the carpet.

Replacing a door bottom sweep is a 20-minute job. Replacing the carpet and the subfloor padding underneath is a multi-week tenant interruption. The math is obvious if you walk the doors before June 15.

What to do with the findings

If you walk the property and find things you can document, take dated photos. Then make a prioritized punch list. Three categories: must-fix before monsoon, should-fix this year, and watch-list for next inspection.

We do the spring walk on properties across El Paso, Las Cruces, and the Permian basin. The report includes thermal moisture mapping if specified and an action list with budget ranges. We are also the team that performs the work afterward if you want a single-source approach, but the walk-through is delivered as a standalone report either way.

Send us the building. We will walk it before June 15 and tell you what we find.
