When San Bruno gutters fill up
Local foliage creates unique drainage challenges across San Bruno. Trees here are largely evergreen and shed leaves, needles, and seed pods year-round into roof drainage systems. Freezing nights are rare in this coastal setting, so ice dams in gutters are not an issue for homeowners, and snow is rare. However, continuous shedding from local foliage steadily fills channels, restricting rainwater flow before winter storms arrive. Organic buildup combined with standing water creates heavy blockages that pull channels away from rooflines. We recommend cleaning channels at least twice a year, spring and fall, to prevent overflow issues and keep residential rainwater control systems running cleanly through every season.
