Signs it may be time for a new roof
- Leaks in more than one place, or leaks that come back after repairs.
- Wet insulation over large areas, which you may find as soft, spongy spots underfoot or through test cuts.
- A worn-out membrane: brittle, chalky, cracked, shrinking away from walls and edges, or blistered across the field.
- Seams opening in many places instead of one or two.
- Deck damage: rust on a steel deck, soft or sagging areas, or stains spreading across ceilings.
- Patches on patches: a roof that has been repaired so often there is little original roof left.
- Heavy storm damage: torn membrane, peeled edges or lost insulation after a hurricane or tropical storm.
Repair, restore, roof-over or tear-off
Replacement is not the only answer. Repair fits isolated problems on a roof that is otherwise sound. A coating can renew the surface of a tired but dry roof. A roof-over, a new single-ply system installed over the existing roof, can work when there is only one existing roof and the insulation and deck below are dry and solid. A tear-off is needed when the old roof is wet, damaged or already has a roof-over on it. The deciding factor is almost always what is under the membrane, which is why a real inspection matters.
Why waiting can cost more
A roof that is near the end of its life rarely fails quietly. Every season of leaks pushes water into insulation and deck, and wet materials usually have to come off. A roof that could have been covered over can turn into a full tear-off with deck repairs. Planning ahead also lets you choose the timing instead of having a storm choose it for you.
Plan around hurricane season and windstorm rules
Hurricane season runs June 1 through November 30. Many owners prefer to finish a replacement before the busiest weeks of the season. On the Coastal Bend, a new roof should be built to the windstorm code, and buildings that need windstorm certification need the inspection and paperwork done right. See our windstorm certification guide for how that works.
Choosing the new roof
For most Corpus Christi commercial buildings, a white single-ply roof such as TPO, PVC or Duro-Last makes sense in this heat and sun. Our TPO vs PVC vs EPDM guide and Duro-Last roof-over guide walk through the options.
Inside the building: signs you can see without a ladder
- Ceiling tiles that keep staining in new places.
- Rust spots or drips on the underside of a steel deck.
- A musty smell above the ceiling or in one area of the building.
- Higher cooling bills, which can follow wet insulation that no longer insulates.
- Tenants or staff reporting leaks in different rooms after the same storm.
How long commercial roofs last here
Every roof is different. How long one lasts depends on the system, how well it was installed, how it was maintained, how much foot traffic it sees, and what storms it has been through. Strong sun, heat and salt air on the Coastal Bend can shorten the life of a roof that is not cared for. That is why age alone is not a reason to replace. A 20-year-old roof in good shape may have years left, and a newer roof that was poorly installed may not.
What to have in hand before deciding
Get a full inspection with photos and moisture checks, a list of repairs made over the last few years, your warranty terms and whether any coverage remains, and your windstorm certificate if you have one. With those, a roofer can give you a real comparison of repair, restoration, roof-over and replacement for your building, instead of a guess.
One more point: a replacement is also the best chance to fix things the old roof got wrong, such as poor drainage, too little insulation, weak edge details or a dark roof that soaks up heat. Ask your roofer what they would change, not just what they would replace.
