It's definitely better to get rid of roof algae sooner rather than later. To clean a roof occupied by algae, the first thing to do is to read the warranty documents that came with your shingles. These documents usually contain manufacturer recommendations on how to clean their products. If you've misplaced these papers, you can look up the information on the manufacturer's website. Although unleashing the force of a pressure washer on your roof might seem like the easy way out, Gig harbor roofing experts actually warn against it because this can damage the shingles while still doing a poor job of removing algae. That's why you'll often see cleaning professionals use a low-pressure application of bleach and water, which kills the algae and restores the shingles.
