March–April
Shade and the marine layer encourage moss.
Redwood and pine shade keep roofs wet. Marine layer does the rest. By March the north face is green. Left untreated, moss keeps washing into the gutters all next winter.
Treatment vs wash
Spring treatment is from $250 standalone, or $150 added to a demoss. Roof demossing is from $450, and most single-stories run $450–$700. Two-story quoted.
Do the gutters on the same visit
Moss that dies still slides into the trough. Book gutters with the roof and take $100 off the pair. That’s the bundle our price list is built around.
Two-story access
Aptos, Beach Hill, and a lot of Soquel hills are two-story. Roof access is included in the price range, and we’ll confirm it on the call.
