Most homes across New Orleans, Louisiana still have asphalt shingles — and most of those shingles are failing faster than the homeowners realize. The combination of Gulf Coast humidity, 60+ inches of annual rain, and UV exposure that runs nearly year-round grinds through asphalt in 10 to 15 years. Metal roofing lasts 40 to 50 years in the same conditions. If your roof is due for replacement, the question is not just what costs less today — it is what costs less over the life of the home. Big Easy Roofing has installed both materials on homes from Lakeview to New Orleans East, and the performance gap is getting harder to ignore.

Lifespan in New Orleans — 40 Years vs. 10

Asphalt shingle manufacturers advertise 20 to 30-year warranties, but those numbers are based on moderate climates. In New Orleans and the surrounding parishes — Orleans Parish, Jefferson Parish, and across Southeast Louisiana — the reality is different. Constant humidity, thermal cycling from 95-degree summers to mild winters, and intense UV exposure break down asphalt granules years ahead of schedule. Most shingle roofs in the metro area need replacement within 10 to 15 years.

Metal roofs handle these same conditions without degrading. Standing seam panels do not absorb moisture, do not lose granules, and do not crack under thermal expansion. A properly installed metal roof lasts 40 to 50 years in this climate, and some systems carry 50-year manufacturer warranties.

Over a 50-year period, that means one metal roof versus three or four shingle replacements. The numbers add up fast.

Cost Breakdown — Upfront vs. Lifetime

Metal roofing costs $8 to $14 per square foot installed in the New Orleans metro area. Asphalt shingles run $4 to $8 per square
