Gutter cleaning, repair and new gutters in Millbrae, CA

When to clean gutters in Millbrae

Frost is rare in Millbrae, 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 Millbrae rain

The short, hard downpour is what a gutter is sized for. In Millbrae the five-minute rain expected about once in ten years falls at 2.92 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,470 square feet of roof and one 3-by-4-inch downspout about 4,930, 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 Millbrae

Half the homes in Millbrae were built by 1960, 79% before 1980 (ACS 2020–2024). Houses that age have often had their gutters replaced once already; if not, the original runs and the boards behind them deserve a close look. 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.

63% of households own their home, and 64% of homes are detached houses, 3% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
