When Castro Valley gutters fill up
Castro Valley experiences mild winters where freezing nights are rare, ice dams in gutters do not form, and snow is extremely rare. However, dry summer dust combines with fall foliage to pack roof line channels tight. Leaves, needles, and seeds from nearby trees collect in gutters, blocking water flow right before heavy winter rains arrive. Leaf drop usually peaks in late October, making mid-fall the critical moment to clear out channels. We recommend cleaning at least twice a year, spring and fall. A spring cleaning clears residual winter dirt, while a fall cleaning prepares your home for heavy rainfall, keeping rain channels open all year.
