How Often Should You Clean Your Roof in San Diego?
Most San Diego roofs don’t need cleaning every year, but they do need it more often than people think. Here’s how to tell when it’s time, and how to get it done without damaging your roof.
What builds up on San Diego roofs
Near the coast, marine layer and salt air keep roofs damp longer, which helps algae and moss grow. Inland, dust and leaves collect in the valleys of tile roofs and hold moisture. Over time this shows up as dark streaks, green or yellow patches and debris piled between tiles.
Signs it’s time for a cleaning
Black or dark streaks running down the roof, green or yellow growth on tiles, leaves and dirt packed between rows, and gutters that overflow when it rains. If you can see it from the street, your neighbors can too.
How often to clean
It depends on shade, trees and how close you are to the ocean. Homes under trees or near the coast usually need it sooner than sunny inland homes. The best way to know is an inspection. We look at your roof and recommend a schedule that fits it.
What a professional roof cleaning includes
We remove moss, algae, streaks and debris from tile and shingle roofs, clear what’s packed between the rows, and cover and protect your landscaping before we start.
