Roofing in Louisiana is metal that leaks at the fasteners, asphalt that loses its edge in a sideways rain, and porch roofs that hold water against the wall. Hail in the north and uplift in the south are both real. Say which one visited your slope, and whether the ceiling got wet while the yard did not flood.
A Shreveport or Monroe roof takes hail and heat, and the bruise shows up later as grit in the gutter. A Baton Rouge ranch under live oaks fails where leaves pack a valley and rain runs under the tabs. Bayou-country metal bangs loose and admits wind-driven rain at a ridge or a pipe. Low porch and carport roofs, almost flat, are where the water sits and then enters the wall. The main field can look honest while the tie-in is the leak.
Wind does not have to remove a sheet to ruin the deck. It lifts the edge, pushes rain uphill, and wets the boards. The stain shows in a gallery or a back bedroom after the wind, not always during a straight-down shower. Pipe boots crack in the sun. Step flashing at brick rusts. A bath vent boot becomes the leak people blame on the whole slope. If you can look into the attic without walking the roof, daylight and black nails are the report.
Deck wood and termite damage change the job, especially in the southern parishes where Formosan activity hollows fascia and porch roof framing. New surface on a soft deck is a short repair. Skip sheathing on older houses, rotten fascia from overflowing gutters, and a skylight curb that was never flashed all show up as interior stains. Metal can be the right surface and still leak at every screw that missed the rib.
Call with the town and the roof shape. Metal hip, asphalt ranch, or a complicated older roof with a low porch tied in. Say whether the leak needs wind, whether oaks cover the valley, and whether hail left grit. Mention piers or a slab only so the caller knows how the ceiling is built. The trade needs the plane that took the weather and the room that stained. Start there. Call the number on this page.
