Full Tear-Off Replacement for Calcasieu Parish Commercial Roofs
The replacement plan explains tear-off or recover assumptions, insulation and drainage needs, occupied-building phasing, system options, and closeout requirements. Tear-off is the right call when a roof has taken on enough water, or enough storm damage, that patching stops making financial sense. In this parish that point often arrives earlier than owners expect, because a membrane that looks intact from the parking lot can be hiding saturated insulation from a storm that hit years earlier. We run tear-off and replacement projects across the industrial corridor, the casino district, and the retail strips along Highway 90 and I-10, and every one starts with confirming just how far the water actually traveled.
Why Tear-Off Beats Patching on Older Storm-Hit Roofs
A roof that took wind damage during Laura or Delta and got a temporary repair afterward is a common find here. The temporary fix stops the visible leak, but trapped moisture underneath keeps degrading the insulation board and deck fasteners long after the patch goes in. We've opened up roofs where the top membrane looked fine and the iso board underneath had gone soft and dark for a third of the roof's area.
Once insulation is saturated, no amount of surface coating fixes it. The board loses R-value, it stops supporting the membrane properly at seams, and it keeps the deck wet enough to eventually corrode steel decking or rot wood nailers. At that point full removal is the only option that actually resolves the problem instead of masking it.
What Comes Off, and What We Check Underneath
A full tear-off means the membrane, all insulation layers, and any wet cover board come off down to the structural deck. We inspect the deck itself at that point, because steel deck near the Westlake and Sulphur plant corridors sometimes shows corrosion from years of humid, chemically active air even where the roof itself never leaked badly.
Wood nailers at the parapets and curbs get the same scrutiny. Salt air off the ship channel and Calcasieu Lake accelerates fastener corrosion at these transition points faster than in the open field of the roof, and a tear-off is the point where replacing compromised nailers is straightforward instead of a separate mobilization later.
- Complete removal of old membrane, insulation, and cover board to bare deck
- Deck inspection for corrosion or rot before any new material goes down
- Nailer and blocking replacement at parapets, curbs, and drains where needed
- Tapered insulation redesign to correct chronic ponding areas
- Debris containment and haul-off sized to the building's access and dumpster placement
- New system installed to current parish wind uplift requirements
Sizing the Job to Plant and Casino Operating Schedules
Industrial clients near the Sasol complex and the refinery yards often need tear-off staged around plant turnarounds or shift changes, since crane access and material staging can't interfere with plant traffic. We coordinate that scheduling directly with facility maintenance leads rather than treating it as a standard commercial job site.
Casino and hospitality buildings along the lakefront face a different constraint: noise and dust control during operating hours. We stage demolition to the quieter parts of the day where the client needs it and keep debris chutes and containment tight so guest areas below aren't affected.
Handling Wet-Weather Risk During an Active Tear-Off
Gulf Coast afternoon storms are the biggest scheduling risk on any tear-off here, hurricane season or not. We never open more roof area than we can dry in before a forecast storm arrives, and during named-storm season we keep that margin even tighter, planning for the possibility that a system accelerates faster than the forecast predicted.
Temporary protection stays staged on site for the full duration of the project, ready before it's ever needed rather than ordered after damage occurs. If wind shifts a system's track toward the Louisiana coast mid-project, we can button up an open section within hours rather than scrambling to source tarps and boards after the fact.
Replacement System Choices for This Market
Most replacement projects here land on TPO, EPDM, or PVC depending on the building's exposure and budget. Plants and facilities with grease, chemical, or exhaust exposure typically call for PVC's weld-seam chemical resistance. Retail and office buildings usually go TPO for reflectivity against the Gulf sun, and EPDM remains a solid, cost-effective choice for owners who've run it successfully on other buildings in their portfolio.
Whatever the membrane, the fastening pattern and perimeter detailing get engineered for the building's actual wind exposure category, which for a lot of Calcasieu Parish buildings is more severe than the original 1990s or 2000s-era permit accounted for.
Questions Owners Ask Before Committing to Tear-Off
How do I know if I need a tear-off instead of a repair?
If moisture surveys or core cuts show wet insulation across a meaningful part of the roof, repair only delays a full replacement while the deck keeps degrading underneath. We walk owners through the core-cut results directly so the decision is based on what's actually found, not a guess.
What happens to the old roofing material?
It gets removed, containerized, and hauled off site. Metal components go to recycling where local haulers take them; membrane and insulation go to disposal.
Can you tear off a section at a time on an occupied building?
Yes, phased tear-off is standard practice for us on occupied retail, casino, and plant buildings. We size each day's open area to what can be fully dried in before that section is left overnight.
Will you find damage you didn't expect once the old roof is off?
Sometimes, particularly deck corrosion near the industrial corridor or nailer rot at parapets. We document any additional finding with photos before proceeding so the owner sees exactly what was found and why it needs addressing.
How does hurricane season affect tear-off scheduling?
We build extra dry-in margin into every schedule from June through November and avoid opening large sections when a system is anywhere in the Gulf, even one not forecast to reach Southwest Louisiana.
