When to clean gutters in Corte Madera
Frost is rare in Corte Madera, 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 Corte Madera rain
Gutters are sized for the worst few minutes of a storm, not for the year. In Corte Madera the five-minute rain expected about once in ten years falls at 3.77 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 1,910 square feet of roof and one 3-by-4-inch downspout about 3,820, 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 Corte Madera
Half the homes in Corte Madera were built by 1960, 79% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. 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.
69% of households own their home, and 71% of homes are detached houses, 8% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.
