When to clean gutters in Marrero

Frost is rare in Marrero, and in many years there is none (NOAA normals). With no hard freeze to strip the trees, the fall cleaning follows the leaf drop itself; book it once the trees over the roof are bare, and plan a second visit in spring.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Marrero rain

What overwhelms a gutter is a burst, not a season. In Marrero the five-minute rain expected about once in ten years falls at 10.54 inches an hour (NOAA Atlas 14 Volume 9). At that rate one 2-by-3-inch downspout drains about 680 square feet of roof and one 3-by-4-inch downspout about 1,370, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.

The houses in Marrero

Half the homes in Marrero were built by 1974, 66% before 1980 (ACS 2020–2024). In a neighborhood that age, many houses are on their second set of gutters or due for one, and the fascia board behind them is worth checking at the same visit. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.

67% of households own their home, and 78% of homes are detached houses, 4% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
