New Orleans sees some of the most intense rainfall rates in the country during summer thunderstorms. When two inches of rain falls in 30 minutes, your roof handles more water volume than most flashing systems were designed to manage. Skylight flashing relies on gravity and proper overlap to channel water down the roof. When rain comes sideways during a storm with 40 mph winds, water gets forced under shingles and through gaps that would never leak during light rain. The combination of high humidity, intense UV exposure, and thermal expansion from 95-degree summer heat also degrades sealants faster than in drier climates.
Heritage Roofing has repaired skylights across Orleans Parish for years. We know the common installation mistakes from the post-Katrina building boom when contractors rushed jobs to meet demand. We know which skylight brands hold up in this climate and which ones develop gasket failures after five years. We also understand local permit requirements and inspection procedures. When we pull a permit for a skylight repair, we know what the inspector will check and we build the repair to pass on the first visit.
