New Orleans experiences some of the harshest roofing conditions in America: average humidity over 90%, heat index days exceeding 100°F, and 62 inches of annual rainfall accelerate the degradation of asphalt shingles. Thermal cycling caused by 150-170°F roof surface temperatures followed by rapid cooling from afternoon storms cracks and curls shingles at double the rate of moderate climates. Moisture constantly infiltrates the roof deck, weakens the plywood substrate, and feeds algae growth that further degrades shingle reflectivity and accelerates UV damage. A 30-year shingle roof that lasts 25-30 years nationally may realistically last only 15-20 years in New Orleans without proper materials and maintenance. Big Easy Roofing specializes in helping homeowners understand these unique climate challenges and select roofing systems built to withstand the Big Easy’s relentless heat, humidity, and moisture.
