New Orleans sits below sea level in the Mississippi River Delta. Hurricane Katrina in 2005 flooded roughly 80 percent of the city; Hurricane Ida in 2021 caused widespread wind-driven rain intrusion and roof damage even with the rebuilt levees holding. Louisiana consistently ranks among the top three states in total NFIP claims paid nationally.
Within the home, aging cast-iron drain lines collapse, flat mid-century roofs pool water and leak, and foundation slabs transmit ground moisture during heavy rainfall. Category 2 water degrades to Category 3 faster in subtropical conditions — the difference between a $3,000 drying project and a $25,000 rebuild often comes down to same-day extraction.
Louisiana follows IICRC S500. Louisiana's Commissioner of Insurance requires insurers to acknowledge claims within 15 days and accept or deny within 30 days of proof of loss — know your rights. Request daily moisture logs from your contractor and call 24/7 immediately.
