How often should you clean gutters in south Louisiana?

The short answer

Twice a year for most homes in Ascension Parish and Greater Baton Rouge: once in late fall, and once in spring. Heavy tree cover over the roof can push that to three.

If you have almost no trees over the house, once a year in late fall is genuinely enough. We'll tell you that rather than sell you a schedule you don't need.

Why the national advice doesn't fit

Every national gutter company runs a fall cleaning campaign. That makes sense in most of the country, where deciduous trees drop in October and November and then go quiet until spring.

Down here, our signature tree doesn't work that way. Live oaks shed in spring. LSU AgCenter describes it plainly: live oaks keep their leaves all year-round except for the small window when they flush new growth in springtime — and as those old leaves fall, the trees also drop catkins.

Catkins are the real problem. They're stringy, they come down in enormous volume, and they mat together into a dense pack that water can't move through. In a gutter they're worse than leaves. And they arrive in March and April.

So a fall-only schedule leaves your gutters packed through the entire spring and into the start of hurricane season — which is exactly when you need them working.

The schedule that actually fits here

• Late fall (November–December) — pines, sweetgums, and the general hardwood drop. Get it done after most of it has fallen.
• Spring (April–May) — live oak leaves and catkins. Ideally before June, so you go into hurricane season clear.

What happens if you skip it

Water goes over the edge instead of down the downspout. In a place that gets 62 inches of rain a year, that adds up fast. It saturates the soil against your foundation, and Louisiana clay swells and shrinks with moisture.

Fascia rots. The board your gutter hangs on stays wet. Once it's soft, the gutter starts pulling away, which makes the problem worse.

You get mosquitoes. The Louisiana Department of Health lists routine gutter cleaning as a mosquito-control measure, noting that clogged gutters “can produce millions of mosquitoes annually.” A gutter full of wet leaf pack is close to ideal habitat.

And in winter, standing water sits against your roof edge instead of draining, which works at the shingles right where they're most vulnerable.

Does a gutter guard mean you can stop?

It means far less often, not never. A well-matched guard takes most homes from twice a year to a check-up once a year. What no guard does is make gutters maintenance-free forever — fine grit, pollen and shingle granules still collect on top of any system.

Anyone who tells you that you'll never touch a ladder again is overselling. Here's an honest look at the options.
