Marin County packs a lot of different conditions into a small space, and gutters face different problems in each part of it. Kentfield and the Ross Valley sit under Mount Tam's heaviest storms. Mill Valley and Larkspur's canyons sit under redwoods that drop debris all year. Sausalito and Tiburon deal with salt air and wind off the bay, while Corte Madera's flats stay wet long after a storm. Pick your town below to see what we look for there.
