Commercial Roofing Challenges in Jefferson Parish
Why Metairie Commercial Roofs Face Extra Pressure
Commercial roofs in Jefferson Parish face the same hurricane and weather threats as residential, but the stakes are different—business interruption, inventory loss, and tenant relationships add financial dimensions beyond the roof itself:
Hurricane Wind Uplift
Impact: Large commercial roof areas create significant wind uplift forces during hurricanes. Edge and corner zones experience pressures 2-3x higher than field areas. Improperly secured membranes can peel back, exposing the building interior.
Our Solution: We design commercial systems with FM Global-rated attachment methods appropriate for wind zone requirements. Enhanced perimeter fastening, proper edge termination, and rated cover boards provide the uplift resistance Jefferson Parish commercial buildings require.
Ponding Water
Impact: Flat commercial roofs with inadequate slope or drainage hold water after heavy rain—common in Metairie's 60+ inch annual rainfall. Ponding accelerates membrane deterioration, adds structural load, and promotes algae growth.
Our Solution: Proper roof design includes adequate slope (minimum 1/4" per foot to drains), correctly sized and positioned drains, and tapered insulation systems where needed. We evaluate drainage during every inspection and quote.
HVAC & Penetration Density
Impact: Commercial roofs typically have numerous penetrations—HVAC units, exhaust fans, plumbing vents, electrical conduits, skylights. Each penetration is a potential leak point, especially as original flashings age.
Our Solution: We use prefabricated curbs, proper flashing techniques, and membrane boots designed for long-term performance. For existing roofs, penetration flashings are often the first failure point and can be replaced during maintenance.
Thermal Movement
Impact: Commercial roof surfaces reach 160°F+ on summer afternoons and can drop 80+ degrees overnight. This thermal cycling causes expansion/contraction that stresses membranes and flashings, especially at seams and terminations.
Our Solution: Single-ply membranes like TPO and EPDM handle thermal movement well when properly detailed. Reflective white TPO reduces thermal stress by lowering surface temperatures. Proper attachment methods allow controlled membrane movement.
Business Disruption Concerns
Impact: Unlike residential work, commercial roofing affects business operations. Noise, debris, and parking impacts during installation; leak potential during work; emergency repair needs can't wait for convenient timing.
Our Solution: We schedule around business needs—overnight work when required, phased installation to maintain operations, coordination with tenants and property managers. Our emergency response addresses leaks quickly to minimize inventory and equipment damage.
Commercial Roofing by Metairie Business District
Different commercial areas in Jefferson Parish have different building types and roofing needs:
Veterans Boulevard Corridor
Major retail corridor with big-box stores, shopping centers, restaurants, and medical offices. Buildings range from 1970s-era construction to recent retail development. Mix of owner-occupied and investor-owned properties.
Large retail footprints often have original roofs now 20-30+ years old. Multi-tenant properties require coordination across businesses. Insurance requirements and lease obligations often drive replacement decisions.
Causeway Boulevard Area
Office buildings, medical facilities, and light industrial. Higher-quality construction typical of corporate and medical tenants. Some multi-story structures.
Building owners and property managers prioritize tenant comfort and lease compliance. Premium roofing systems often justified by tenant expectations. Multi-story buildings require crane access or material hoist.
Airline Drive Corridor
Strip retail, automotive services, warehouse/distribution, and light manufacturing. More price-sensitive market with smaller owner-operated businesses.
Cost-effective systems like TPO and EPDM popular. Smaller roof sizes allow quicker installation. Business owners often directly involved in decisions. Roof-mounted equipment (HVAC, exhaust) common.
Industrial / Warehouse Districts
Large-footprint industrial and distribution buildings. Lower roof slope tolerances. Often 24/7 operations that cannot shut down for roofing work.
Large roof areas benefit from single-ply efficiency. Must maintain operations during installation. Forklift traffic and loading dock access affect staging. Energy costs make reflective roofing attractive.
Lakeside Mall / Power Center Area
Regional retail destination with major anchor stores and inline retail. Professional property management with corporate maintenance standards.
National tenant requirements often specify roofing standards. Property management coordinates across multiple tenants. Hurricane preparation protocols for retail continuity.

Commercial Roofing Systems for Metairie Buildings
Each commercial roofing system has strengths suited to different building types and owner priorities. Here's what performs well in Jefferson Parish:
TPO (Thermoplastic Polyolefin)
Why for Metairie
White reflective surface reduces cooling costs significantly in Louisiana's hot climate—typical savings of 10-20% on cooling bills. Heat-welded seams provide superior watertight performance. Handles ponding water well.
Best For
Retail centers, office buildings, any facility with significant cooling costs. New construction and re-roofing over existing systems.
Considerations
Requires trained heat-welding installation. Quality varies by manufacturer—we install premium brands (GAF, Carlisle, Firestone) with strong warranty backing. 60-mil or 80-mil thickness recommended for Gulf Coast.
EPDM (Ethylene Propylene Diene Monomer)
Why for Metairie
Proven rubber membrane with 50+ year track record. Excellent UV and ozone resistance. Lower cost than TPO while providing reliable waterproofing. Flexible in temperature extremes.
Best For
Budget-conscious projects, buildings where reflectivity is less important, existing EPDM roof replacement.
Considerations
Standard black EPDM absorbs heat (white available at premium). Adhesive or mechanically attached. Seams use tape/adhesive rather than welding—quality seam work is critical. We've installed EPDM for 6+ years with excellent results.
Modified Bitumen
Why for Metairie
Multi-ply redundancy provides excellent waterproofing even if one layer is damaged. Superior puncture resistance for roofs with foot traffic or equipment. SBS-modified products handle thermal cycling well.
Best For
Industrial buildings, roofs with regular maintenance traffic, areas around rooftop equipment, projects prioritizing long-term durability over energy efficiency.
Considerations
Heavier than single-ply—verify structural capacity. Torch-applied installation requires fire safety measures. Self-adhered (cold-applied) options available where open flame is restricted.
Built-Up Roofing (BUR)
Why for Metairie
Traditional system with decades of proven Gulf Coast performance. Multiple waterproofing layers provide redundancy. Gravel surface provides excellent UV protection and additional weight for wind resistance.
Best For
Industrial facilities, warehouses, and buildings where proven long-term performance is prioritized over installation speed.
Considerations
Labor-intensive installation means higher labor costs. Hot asphalt application has odor and fume considerations. Gravel surface makes leak detection more difficult. Being replaced by modified bitumen in many applications.
Standing Seam Metal
Why for Metairie
Ultimate hurricane performance with 150+ mph wind ratings when properly installed. 40-60+ year expected life. Lowest lifetime cost despite higher initial investment. Excellent for high-visibility commercial applications.
Best For
Commercial buildings where long-term ownership is planned, facilities requiring maximum storm protection, architectural applications where appearance matters.
Considerations
Higher upfront cost ($10-16/sq ft) but amortized over 50+ years is very competitive. Requires structural capacity for panel spans. Thermal expansion/contraction must be accommodated in design.
Spray Polyurethane Foam (SPF)
Why for Metairie
Seamless application eliminates leak points at seams. Excellent insulation value (R-6.5 per inch). Lightweight. Can be applied over existing roofing in many cases.
Best For
Irregularly shaped roofs, roofs with numerous penetrations, energy retrofit projects where insulation improvement is a priority.
Considerations
Requires specialized installation equipment and trained applicators. Protective coating required over foam. Repairs also require specialized equipment. Less common than membrane systems.

Our Commercial Experience in Metairie
Commercial roofing in Jefferson Parish is a significant part of our business. We've completed projects ranging from 3,000 sq ft strip center units to 80,000+ sq ft warehouse facilities, learning the specific requirements of commercial work in this market.
What makes commercial roofing different from residential isn't just the systems—it's the stakeholder complexity. Property owners, property managers, tenants, insurance companies, and sometimes corporate facilities departments all have input and requirements. We've learned to navigate these relationships efficiently, communicating clearly and delivering documentation that satisfies everyone's needs.
The post-Katrina commercial construction boom taught us a lot about what works long-term in this climate. Buildings constructed in 2006-2010 are now showing which roofing systems performed and which didn't. The patterns are clear: properly specified and installed single-ply systems last. Budget-driven shortcuts don't. We've applied those lessons to every commercial specification we write.
Hurricane preparedness is particularly critical for commercial properties. Business interruption, tenant displacement, and inventory loss add financial dimensions that homeowners don't face. We design systems with these stakes in mind—the incremental cost of hurricane-rated specifications is trivial compared to the business losses an inadequate roof can cause.
We've also built relationships with the commercial property management community across Jefferson Parish. They know we answer the phone, show up when scheduled, and deliver what we promise. That reputation keeps us busy with commercial work year-round, through relationships built on consistent performance.

FAQ
Frequently Asked Questions
What is the best commercial roofing system for Metairie?
For most Metairie commercial buildings, TPO (Thermoplastic Polyolefin) offers the best combination of performance, cost, and energy efficiency. Its white reflective surface reduces cooling costs significantly in Louisiana's climate, heat-welded seams provide excellent waterproofing, and 20-25 year warranties are available. That said, building use, budget, and specific requirements may make other systems more appropriate—we evaluate each building individually.
How long does commercial roof replacement take?
Most commercial projects take 3-10 working days depending on roof size and complexity. A typical 10,000 sq ft retail space completes in 3-5 days. Larger projects, complex flashing work, or weather delays extend timelines. We provide detailed schedules during proposal and update property managers daily during installation.
Can you work around our business operations?
Absolutely. We routinely schedule work to minimize business impact—phased installation to maintain access, overnight or weekend work when needed, coordination with tenant schedules. Tell us your operational constraints and we design the installation plan around them.
Do commercial roofs in Jefferson Parish require permits?
Yes. Jefferson Parish requires permits for commercial roofing work. We handle the permit process including application, plan submission, and inspection scheduling. Commercial permits typically take 5-7 business days to process.
What warranty do you offer on commercial roofing?
Commercial warranties depend on system and manufacturer. Premium TPO and EPDM systems offer 20-30 year manufacturer warranties with no-dollar-limit (NDL) coverage available. We provide a 10-year workmanship warranty on all commercial installations. Warranty terms are detailed in every proposal.
Can you install over the existing roof?
Sometimes. If the existing roof system and deck are in acceptable condition and building code allows, recover installation is an option. It's typically 15-25% less expensive than tear-off and replacement. We evaluate during inspection whether recover is appropriate for your building.
How do you handle emergency commercial roof leaks?
We provide rapid response for commercial emergencies. Our goal is temporary measures—tarps, emergency patches, redirecting water—to stop active damage while we assess the situation and plan permanent repairs. Call (504) 592-7728 for emergency service.
What maintenance do commercial roofs require?
We recommend semi-annual inspections (spring and fall) plus inspection after major storms. Routine maintenance includes drain clearing, debris removal, sealant touch-up, and addressing minor issues before they become major repairs. We offer maintenance programs for commercial clients.
Will a new roof reduce my energy costs?
Likely yes. White reflective roofing (TPO, white EPDM, coatings) significantly reduces cooling loads—typical savings of 10-20% on cooling costs. Combined with proper insulation upgrades, new roofing often provides noticeable energy savings that offset some of the investment.
How do you price commercial roofing projects?
Commercial roofing is priced per square foot based on system type, building requirements, and project complexity. We provide detailed proposals breaking down materials, labor, and options. Quotes require site inspection—too many variables affect pricing to quote accurately without seeing the roof.
