Summary
New Orleans homeowners face roofing challenges that most of the country does not, including hurricane-force winds, year-round humidity, and intense summer heat that accelerate wear on every roofing material. Big Easy Roof Team covers the essential roofing knowledge every New Orleans homeowner should have to protect their property.
Your roof is the single most important protective layer between your home and the elements. Big Easy Roof Team built this guide around the specific conditions New Orleans homeowners deal with: hurricanes, sustained humidity above 70 percent, torrential summer downpours, and intense UV exposure.
Whether you own a residential home in Lakeview, a shotgun double in the Marigny, or a commercial building on Magazine Street, understanding how your roof works and what threatens it will help you make better decisions.
New Orleans sits in a high-velocity hurricane wind zone with annual rainfall exceeding 60 inches, humidity that promotes algae and mold, and summer temperatures that push attic spaces above 140 degrees. The Louisiana building code mandates hurricane straps, specific nailing patterns, and underlayment standards designed for wind-driven rain.
Impact-resistant asphalt shingles with algae-resistant granules, metal roofing, and slate are the strongest performers because they resist moisture, algae growth, and wind uplift while tolerating extreme heat.
Untreated wood shakes and standard three-tab shingles without algae-resistant coatings are the weakest choices for this climate. Tile roofing is viable for homes with adequate structural support.
A roof with higher solar reflectance can reduce attic temperatures by 20 to 40 degrees and lower air conditioning costs noticeably.
A valid Louisiana State Licensing Board for Contractors license, general liability insurance, workers’ compensation coverage, and local references.
Itemized materials, labor, permit fees, tear-off and disposal costs, an allowance for deck repairs, warranty terms, and a projected timeline. Get at least three estimates.
Inspection, permit filing, material procurement, complete tear-off, deck inspection and repair, drip edge and underlayment, new roofing material per high-wind specs, flashing, cleanup, and final city inspection.
Proper ventilation is one of the most overlooked factors in roof longevity. In New Orleans, inadequate ventilation leads to moisture buildup, mold, and wood rot.
At least twice a year (spring and fall) and after any named storm. Schedule a professional inspection every two to three years.
Clogged gutters during New Orleans downpours cause water to seep under the roof edge and saturate fascia boards. Regular maintenance prevents this.
Yes. High humidity creates ideal conditions for algae, moss, and lichen that break down shingle granules and retain moisture.
Hurricane-force winds can lift, crack, or tear away shingles, peel back flashing, and in severe cases separate the roof structure from the walls. Learn how to manage storm roof damage.
A roof rated for 30 years in a temperate region may show significant wear by year 20 in New Orleans due to intense UV exposure and sustained humidity.
If your roof is approaching 20 years of age, if you have noticed signs it is time to replace, or if a recent storm left visible damage, a professional inspection is the right first step.
Big Easy Roof Team provides straightforward roofing guidance backed by local experience. Whether you need an inspection, a repair, or a full replacement, we build every project around the demands of the local climate.
We serve New Orleans, Metairie, Kenner, Slidell, Baton Rouge, and throughout Louisiana and Florida.

Asphalt shingle roofs typically last 20 to 25 years in this climate. Metal roofs last 50 years or more. Slate can exceed a century with proper maintenance.
Wind damage from hurricanes is the most frequent acute issue. Algae and moss growth from sustained humidity is the most common chronic problem.
If damage is limited to a small area, a repair may suffice. If the roof is over 20 years old, shows widespread granule loss, has multiple leaks, or has major storm damage, replacement is usually more cost-effective.
Yes. A new roof is one of the highest-return home improvements, especially in the New Orleans market where buyers are aware of hurricane and water damage risks.
