Metal roofing is not new, but most homeowners in New Orleans still default to asphalt shingles without considering what metal actually brings to the table. That is starting to change. After Hurricane Ida tore through Orleans Parish and Jefferson Parish in 2021, a lot of people watched their neighbors’ metal roofs survive while their own shingles ended up in the street. Here are five metal roofing benefits that do not get enough attention — especially for homes in Southeast Louisiana. If you are thinking about your next roof, Big Easy Roofing can walk you through the options.
This is the one that changes the math on everything else. A metal roof lasts 40 to 50 years in New Orleans. Asphalt shingles last 10 to 15. That is not a typo, and it is not based on manufacturer warranties written for homes in Michigan. That is real-world performance in a city with 60+ inches of rain per year, sustained humidity above 75%, and UV exposure that runs nearly year-round.
The reason is simple — metal does not absorb moisture. Asphalt shingles soak up water at a microscopic level, and that moisture accelerates granule loss, curling, and cracking. In drier climates, this process takes 20 to 25 years. In New Orleans, Louisiana, it happens in half that time.
Think about what that means financially. Over 50 years, you install one metal roof or you replace your shingles three to four times. Each shingle replacement means tear-off, disposal, permits under Louisiana’s Act 239, and the LSLBC-licensed contractor fees that go with it. One metal roof versus four shingle jobs — the lifetime cost is not even close.
If your current roof is nearing the end of its life, request a metal roof estimate to see the numbers side by side.
Every homeowner in New Orleans knows what June 1st means. Hurricane season runs six months, and it only takes one bad storm to destroy an asphalt shingle roof. Metal roofs rated for 140+ mph winds can handle Category 4 hurricanes — the kind of storm that flattened shingle roofs across Gentilly, Lakeview, and New Orleans East during Hurricane Ida.
Standing seam metal is the best-performing style for wind resistance. The panels interlock with concealed fasteners, which means there are no exposed edges for wind to catch and peel back. Compare that to three-tab or even architectural shingles, where individual tabs can lift once the adhesive strips degrade — and in NOLA’s heat, they degrade fast.
Metal is also lighter than tile and similar in weight to architectural shingles, so you get superior wind performance without adding structural load to your home. That matters for older construction in neighborhoods like the Garden District, Uptown, and Mid-City where the framing was not built for heavy roofing loads.
New Orleans has an 8-month cooling season. Most homes run air conditioning from March through October, and the electricity bills during July and August can be punishing. Metal roofs reflect solar radiation rather than absorbing it, and according to the U.S. Department of Energy, that reflectivity can reduce cooling costs by 15 to 30 percent.
On a home with summer electric bills of $300 to $400 per month, that savings translates to $500 to $1,200 per year. Over the 40 to 50-year life of a metal roof, you are looking at $20,000 to $50,000 in cumulative energy savings. That alone covers a big portion of the metal roof’s cost.
The effect is strongest with light-colored panels and Galvalume-coated standing seam systems, but even darker metal colors outperform asphalt. Metal dissipates absorbed heat much faster once the sun goes down, which means your attic stays cooler overnight instead of radiating stored heat back into the house for hours like asphalt does.
Drive through any neighborhood in New Orleans and you will see dark streaks running down shingle roofs. That is Gloeocapsa magma — a cyanobacteria that thrives in warm, humid conditions. It feeds on the limestone filler in asphalt shingles, and once it takes hold, it shortens the roof’s lifespan and makes the home look neglected.
Metal roofs do not give mold or algae anything to feed on. The surface is inorganic, non-porous, and does not absorb the moisture that biological growth needs. In a city surrounded by water — the Gulf of Mexico to the south, Lake Pontchartrain to the north, the Mississippi running through the middle — that moisture resistance matters every single day.
Salt air is the other factor. Homes in Metairie, along the lakefront, and throughout Jefferson Parish get consistent salt exposure that corrodes lesser materials. Quality metal roofing uses Galvalume coating (a zinc-aluminum alloy) or solid aluminum panels that resist salt corrosion for decades. This is the same technology used on coastal commercial and industrial buildings across the Gulf Coast.
If you are not sure where your current roof stands, schedule a roof inspection first so you know what you are working with.
Louisiana’s homeowner insurance market has been one of the toughest in the country since 2020. Carriers have left the state, premiums have doubled or tripled, and homeowners across Orleans Parish and Jefferson Parish are paying $4,000 to $8,000 or more per year for basic coverage.
A wind-rated metal roof is one of the few upgrades that can actually move the needle on your premium. Several Louisiana insurers offer discounts for roofs rated at 140+ mph, and metal standing seam systems qualify. Homeowners have reported savings of 5 to 20 percent on wind and hail coverage — that is $200 to $1,600 per year at current premium levels.
The discount varies by carrier and by your specific roof system, so talk to your insurance agent before the project starts. Get the numbers in writing. When you combine insurance savings with energy savings, the annual return on a metal roof in Louisiana is stronger than most home improvements.

Higher upfront cost is the main one — $8 to $14 per square foot versus $4 to $8 for asphalt shingles. Rain noise can be a factor without proper insulation and solid decking. There are also fewer metal roofing contractors in the area compared to shingle installers, so availability can be tighter during busy seasons. Denting from large hail is possible but rare in the New Orleans metro.
Metal roofs reflect solar heat and can reduce cooling costs by 15 to 30 percent. In New Orleans, where air conditioning runs 8 or more months per year, that translates to $500 to $1,200 in annual savings depending on the size of the home and the current energy setup.
Yes. The longer lifespan and lower maintenance requirements appeal to buyers. A metal roof also makes the home easier to insure, which is a real selling point in Louisiana’s tight insurance market. Buyers are factoring insurance costs into purchase decisions more than ever.
40 to 50 years with minimal maintenance. Some metal roofing systems come with 50-year manufacturer warranties. Compare that to 10 to 15 years for asphalt shingles in the same climate. The humidity, UV exposure, and thermal cycling in New Orleans cut asphalt lifespans well below the national average.
With modern installation over solid decking and insulation, rain noise is comparable to shingles. The loud metal roof reputation comes from older agricultural buildings, barns, and carports that had no insulation or decking underneath. A residential standing seam installation with proper underlayment is a completely different experience.
