If you manage a commercial property in Waco, Temple, Killeen, or anywhere across Central Texas, your flat roof has just come through the hardest stretch of its year — months of intense UV, thermal cycling, and whatever storms came through.
October is the window to deal with what that left behind. Here’s the punch list.
Ponding Water and Drainage
Low-slope roofs are designed to drain, not to hold water. Standing water that’s still present 48 hours after rain is a problem. It adds significant dead load, accelerates membrane breakdown, and turns any small seam failure into a continuous leak.
Check:
- Internal drains for debris baskets that are missing, crushed, or packed
- Scuppers and overflow scuppers for blockage
- Downspout connections for separation
- Low spots and tapered insulation that’s compressed or saturated
- Staining rings on the membrane that show where water sits even when it’s currently dry
Seams and Field Membrane
On TPO and PVC, seams are heat-welded and they’re the first thing to check. When checking out modified bitumen, look at the laps. For EPDM, check the adhesive seams and any field-applied tape.
Look for lifted edges, fishmouths, wrinkles, punctures, and areas where the membrane has visibly shrunk and is pulling at the perimeter. On aged single-ply, chalking and a loss of surface flexibility tell you the system is approaching the end of its service life.
Flashings and Penetrations
The overwhelming majority of commercial roof leaks start at a penetration or a transition, not in the open field. Every one of these deserves a look:
- Curb flashings around rooftop HVAC units
- Pipe penetrations and their sealant pans
- Conduit and gas line supports
- Vent stacks and exhaust fans
- Parapet wall base flashings and counterflashing
- Coping cap joints and fasteners
- Skylights and hatches
- Expansion joints
Pitch pans in particular need to be checked and topped off — the sealant shrinks, and once it’s cupped it’s collecting water directly against the penetration.
Rooftop Traffic Damage
This is the one property managers most often miss. Every HVAC technician, satellite installer, and window cleaner who’s been on that roof this year walked across the membrane. Tools get dropped. Refrigerant lines get dragged. Screws and metal shavings end up underfoot.
Look at the paths between the access hatch and the equipment. That’s where punctures are. If you don’t have walk pads installed along those routes, that’s a cheap fix with a real payback.
Also check condensate lines — units discharging directly onto the membrane cause chronic saturation in one spot.
Perimeter and Edge Metal
Edge metal takes the worst of the wind uplift. Check that fasteners are tight, cleats are engaged, and no sections have lifted. A failed edge detail during a high-wind event is how a small problem becomes a peeled-back section of roof and an interior full of water.
Documentation and Warranty Compliance
Worth saying plainly: most manufacturer warranties on commercial systems require documented periodic inspection and maintenance. If a claim ever comes up and you can’t produce records, that conversation goes badly.
Keep dated photos, written reports, and a log of repairs. It costs nothing and protects an asset worth a great deal.
Budget Timing
Fall is also when a lot of organizations are setting next year’s capital budget. An honest condition assessment right now tells you whether you’re looking at another year of maintenance or whether a recover or replacement needs a line item. Finding that out in October is considerably better than finding out in February when a leak forces the decision.
What a Maintenance Program Actually Saves You
The math on commercial roofing is not subtle. Scheduled maintenance costs a fraction of reactive repair, and reactive repair costs a fraction of premature replacement — before you count tenant disruption, damaged inventory, ruined ceiling tile, and the interior work that follows a leak.
A roof that gets looked at twice a year and has its small problems fixed while they’re small routinely outlasts an identical roof that gets attention only when water shows up inside.
