When to clean gutters in San Marcos
Frost is rare in San Marcos, 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 San Marcos rain
The short, hard downpour is what a gutter is sized for. In San Marcos the five-minute rain expected about once in ten years falls at 2.78 inches an hour (NOAA Atlas 14 Volume 6). At that rate one 2-by-3-inch downspout drains about 2,590 square feet of roof and one 3-by-4-inch downspout about 5,180, 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.
San Marcos is dry by national standards, about 15 inches in a normal year, but much of the rain that does come can arrive in short, hard storms: the five-minute downpour expected once in ten years still runs at 2.78 inches an hour. Where gutters are used here, the job is moving that burst away from the foundation, and keeping a dry season’s dust and debris from blocking the first storm.
The houses in San Marcos
Half the homes in San Marcos were built by 1994, 28% 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.
63% of households own their home, and 51% of homes are detached houses, 10% townhouses. In a townhouse or HOA community, check who owns the gutters and what colors are allowed before booking.
