The right roofing material can cut summer cooling costs by 20 to 40 percent in New Orleans, where temperatures regularly exceed 95 degrees and humidity stays above 90 percent for months at a time. Big Easy Roof Team installs energy efficient roofing systems designed specifically for New Orleans homes, from reflective metal roofs to cool-roof-rated shingles that keep Entergy bills under control.
New Orleans summers are not just hot. They are heavy. The combination of 95-degree days and humidity that refuses to drop below 80 percent creates a heat load that pushes air conditioning systems to their limits from May through October. Your roof is the single largest surface absorbing that heat, and the material sitting on top of your home has a direct, measurable impact on what Entergy charges you every month. At Big Easy Roof Team, we help homeowners across New Orleans choose roofing materials that fight the heat instead of trapping it.
The average New Orleans household spends significantly more on summer cooling than the national average. Much of that cost comes from heat radiating through the roof into the attic and down into living spaces. Shotgun houses, double shotguns, raised Creole cottages, and camelback homes present unique challenges because of their age, limited attic space, and original construction methods that predate modern insulation standards. Choosing the right roofing material during a replacement can change the energy profile of these homes dramatically.
In New Orleans, a dark-colored asphalt roof can reach surface temperatures above 160 degrees Fahrenheit on a summer afternoon, radiating that heat into the attic and forcing air conditioning to run constantly. The right roofing material reflects solar energy instead of absorbing it, reducing attic temperatures by 30 to 50 degrees and cutting cooling costs measurably.
Louisiana’s climate creates a unique problem. It is not just the heat. The humidity prevents nighttime cooling that drier climates enjoy. In Phoenix, a roof cools down significantly after sunset. In New Orleans, the moisture-laden air acts as an insulating blanket, keeping rooftop temperatures elevated well into the night. Your AC keeps running long after dark.
This means roofing decisions in New Orleans have a bigger financial impact than in most other cities. A roof that reflects even 30 percent more solar radiation translates to real dollar savings over the 20- to 30-year life of the material. For homeowners in neighborhoods like Uptown, Mid-City, Lakeview, or the Bywater, where many homes date to the early 1900s or older, a roof replacement is the single best opportunity to improve energy performance.
The U.S. Department of Energy estimates that cool roofing materials can reduce peak cooling demand by 10 to 15 percent. In a climate as demanding as New Orleans, those percentages translate to hundreds of dollars annually on Entergy bills. Over the life of a roof, that savings often covers a significant portion of the installation cost.
Metal roofing with a reflective finish is one of the most energy efficient options available for New Orleans homes. It reflects up to 70 percent of solar energy, sheds rain instantly, resists wind damage up to 140 mph, and lasts 40 to 70 years with minimal maintenance.
Standing seam metal roofs have become increasingly popular across New Orleans neighborhoods. They perform exceptionally well against the three biggest threats in this climate: heat, rain, and wind. The reflective surface keeps attic temperatures significantly lower than traditional asphalt shingles, and the interlocking panel design provides superior wind resistance during hurricane season.
For shotgun houses and other narrow NOLA home styles, metal roofing is particularly effective. These homes often have limited attic space, which means heat transfer from the roof to the living area happens faster. A reflective metal roof addresses this problem at the source by preventing heat absorption in the first place.
The upfront cost of metal roofing runs higher than asphalt, typically $8 to $14 per square foot installed. But the combination of energy savings, longevity, and reduced maintenance makes it the lowest total cost of ownership for most New Orleans homeowners. Big Easy Roof Team installs standing seam and corrugated metal roofing systems across the metro area. Visit our metal roofing page for details on the systems we offer.
Cool roof shingles use specially engineered granules that reflect more solar radiation than standard shingles, reducing surface temperatures by 20 to 40 degrees Fahrenheit. They are rated by the Cool Roof Rating Council and work effectively in Louisiana’s subtropical climate while maintaining the traditional appearance of a shingled roof.
For homeowners who want improved energy efficiency without changing the look of their home, cool roof shingles are the practical middle ground. They look like standard architectural shingles but perform significantly better in heat reduction. This matters in historic neighborhoods like the Garden District or the Irish Channel, where maintaining architectural character is important to homeowners and sometimes required by local guidelines.
Cool roof shingles carry an ENERGY STAR rating and meet the Solar Reflectance Index (SRI) standards that qualify for certain utility rebates and tax incentives. Louisiana homeowners should check with Entergy about available rebate programs, as these change periodically and can offset a portion of installation costs.
The cost premium over standard architectural shingles is modest, usually 10 to 20 percent more per square foot. Given that shingle roofs are the most common roofing type in New Orleans, this upgrade path makes financial sense for most homeowners planning a roof replacement.
Clay and concrete tile roofs provide natural thermal resistance because of the air gap between the tile and the roof deck, which acts as a built-in ventilation layer. Tile roofs last 50 to 100 years, resist rot and mold in Louisiana’s humidity, and reduce heat transfer more effectively than flat-laid materials like asphalt shingles.
Tile roofing has a long history in the Gulf South. You can find clay tile roofs on historic buildings throughout the French Quarter and along St. Charles Avenue that have performed for over a century. The material is inherently suited to this climate because it does not absorb moisture, does not support mold growth, and withstands UV exposure without significant degradation.
The thermal advantage of tile comes from its shape. Barrel tiles and S-tiles create a natural air channel between the tile surface and the underlayment. This air gap acts as insulation, slowing heat transfer into the attic. In a climate where rooftop temperatures climb past 150 degrees, that buffer layer makes a meaningful difference.
The main consideration with tile roofing in New Orleans is structural. Tile is heavier than asphalt or metal, and not every roof structure can support the additional weight without reinforcement. Older homes, especially raised shotgun houses and Creole cottages, need a structural evaluation before tile installation. Big Easy Roof Team performs these assessments as part of every tile roofing consultation. Learn about our residential roofing services to explore your options.
Flat roofs on older New Orleans homes benefit from reflective roof coatings, TPO membranes, and rigid foam insulation installed above the deck. These solutions reduce heat absorption on flat surfaces that receive the most direct sun exposure and are most prone to ponding water that traps heat.
Many New Orleans homes have flat or low-slope roof sections, especially camelback homes, double shotguns, and multi-family buildings throughout Mid-City, Treme, and Central City. These flat sections absorb more heat per square foot than sloped roofs because they face the sun more directly during peak hours.
A white or light-colored TPO membrane is one of the best-performing flat roof options for energy efficiency. TPO reflects solar radiation, resists ponding water, and holds up well against the UV intensity that New Orleans delivers. For existing flat roofs in decent condition, a reflective roof coating achieves similar reflectivity benefits at a lower cost than full membrane replacement.
Adding rigid foam insulation above the roof deck during a flat roof replacement is another high-impact upgrade. This approach creates a thermal barrier that stops heat from reaching the attic entirely. For older homes with little or no attic insulation, this single improvement can produce the most dramatic change in cooling costs.
Even the most reflective roof material will underperform if the attic below it has inadequate insulation or poor ventilation. In New Orleans homes, trapped attic heat and moisture combine to create temperatures above 140 degrees, which radiates into living spaces and forces AC systems to work overtime.
Proper attic ventilation allows hot air to escape through ridge vents or gable vents while drawing cooler air in through soffit vents. This airflow reduces attic temperatures significantly and prevents moisture buildup that leads to mold and wood rot. In Louisiana’s humid climate, moisture management is just as important as heat management.
Many older New Orleans homes have insufficient insulation by modern standards. The Department of Energy recommends R-38 to R-60 attic insulation for Louisiana (Climate Zone 2). Homes built before 1980 often have R-11 or less. Upgrading insulation during a roof replacement is the most cost-effective time to do it because the roof deck is already accessible.
Big Easy Roof Team evaluates attic insulation and ventilation as part of every roof inspection. When we recommend a roofing material, we factor in the full thermal system, not just the surface material. A reflective roof paired with proper insulation and ventilation delivers the best energy performance.
If your summer Entergy bills have been climbing, your AC runs constantly without keeping the house comfortable, or you can feel heat radiating from the ceiling on sunny afternoons, your roof is likely part of the problem.
The ideal time to address roofing efficiency in New Orleans is during a planned roof replacement. If your roof is approaching the end of its lifespan (15 to 20 years for asphalt shingles), choosing an energy efficient replacement material gives you decades of savings compared to replacing with the same standard shingles.
You do not have to wait for a full replacement, though. Reflective coatings, improved attic ventilation, and insulation upgrades can improve efficiency on an existing roof that still has years of life remaining.
Before hurricane season is also a smart time to evaluate your roof. Combining storm readiness with an energy efficiency upgrade lets you address two priorities with a single project. Call Big Easy Roof Team at 504-285-5388 to schedule an inspection and discuss your options.

A standing seam metal roof with a reflective finish is the most energy efficient option for most New Orleans homes. It reflects up to 70 percent of solar energy, lasts 40 to 70 years, and handles hurricane-force winds better than most other materials.
Homeowners in New Orleans typically see cooling cost reductions of 15 to 30 percent after installing a reflective or cool-rated roofing material. The exact savings depend on home size, insulation levels, and AC system efficiency.
Yes. The 10 to 20 percent cost premium over standard shingles is typically recovered within five to seven years through lower cooling bills. They also qualify for ENERGY STAR ratings and may be eligible for utility rebates.
Roof color has a significant impact. A dark roof in New Orleans can reach 160 degrees or more on a summer day, while a light-colored or reflective roof stays 50 to 80 degrees cooler. That temperature difference directly reduces the heat load on your AC system.
Metal roofing is ideal for shotgun houses because these homes have limited attic space, which means roof heat transfers into living areas quickly. A reflective metal roof stops heat absorption at the surface, keeping narrow shotgun interiors cooler without relying solely on air conditioning.
Yes. Reflective roof coatings, improved attic insulation, and better ventilation can all improve energy performance on an existing roof. These upgrades are especially effective on older New Orleans homes that were built before modern insulation standards.
