Commercial flat and low-slope roofs face a tough combination in Texas: intense sun, heavy rain, high wind, and hail. Unlike sloped residential roofs, flat roofs do not shed water quickly, so small issues can turn into leaks that disrupt your business. A regular maintenance plan is the best way to protect the roof and your budget.
Why Maintenance Matters for Commercial Roofs
- Extends roof life and delays the large capital expense of replacement.
- Protects inventory, equipment, and tenants from leaks.
- Keeps warranties valid. Many commercial roofing warranties require documented periodic inspections and maintenance.
- Supports insurance claims by documenting the roof's condition before a storm.
How Often to Inspect
Most commercial roofing professionals recommend inspections at least twice a year, typically in spring and fall, plus after any major storm. In Houston, scheduling one before hurricane season is a smart move.
Commercial Roof Maintenance Checklist
Drainage
- Clear drains, scuppers, and gutters of debris.
- Look for ponding water that remains more than about 48 hours after rain. Persistent ponding stresses the membrane and can point to drainage or structural issues.
- Check that drain strainers are in place.
Membrane and Seams
- Inspect seams for separation, especially on single-ply membranes like TPO and PVC.
- Look for blisters, cracks, punctures, and shrinkage.
- Check for hail damage after storms.
Penetrations and Flashing
- Inspect flashing around HVAC units, pipes, vents, and skylights.
- Check pitch pans and sealants, which break down in the sun.
- Inspect parapet walls, coping, and edge metal.
Rooftop Equipment and Traffic
- Look for damage from HVAC service technicians, such as dropped tools or screws.
- Consider walkway pads in high-traffic areas.
- Make sure condensate lines drain properly and do not drip on the membrane.
Keep Records
Keep a log of every inspection, repair, and photo. Good records help with warranty claims, insurance claims after storms, and budgeting for future replacement.
Repair, Restore, or Replace?
Many commercial roofs can be repaired or restored with a coating rather than replaced, if the existing roof is in fair condition and not saturated with water. See TPO vs modified bitumen vs roof coatings for how the options compare.
