The average annual rainfall in Acadiana is well above the national average. When a summer storm rolls through Lafayette, it doesn't drizzle, it dumps. An undersized or poorly installed gutter system simply can't move that volume of water fast enough, and the overflow ends up against your foundation, behind your fascia, or pooling along your roofline.
That water damage is slow, hidden, and expensive by the time most homeowners notice it. 6" seamless gutters are sized and shaped to handle Louisiana's rainfall volume. Custom-fabricated on-site to fit your home precisely, they move water faster and have fewer joints where leaks can develop compared to standard sectional gutters.
Most older homes have 5" gutters, which were standard before climate patterns in the South started producing heavier rainfall events more frequently.
6" gutters move roughly 40% more water than 5" gutters at the same pitch. For Acadiana homes that deal with high-volume summer storms, the upgrade is worth it.
