Roof Cleaning to Remove Mold and Algae

One of the many joys of being a Florida resident is living with year-round high humidity. The lush greenery that thrives in most Florida neighborhoods often traps in moisture, which creates the perfect conditions for fungi and algae to grow on top of roofs. Roof mold, roof algae and roof mildew can drastically drive down property values, and they can even trigger dangerous allergic reactions in some individuals. This guide will explain how to conduct a proper roof cleaning and help you determine if you need a professional roof replacement.

Step-by-Step Roof Cleaning for Algae and Mold Removal

Areas that are permanently shaded by our beautiful trees are especially vulnerable to mold and algae. Moldy shingles can become stained and damaged over time, and the spores can seep into your attic, which would contaminate your home’s air quality. Fortunately, roof mold, algae and mildew can be taken down with a regular bleach solution. Of course, that means you need to take some basic precautions, so wear rubber gloves and a breathing mask to protect yourself from fumes

  1. Protect Your Lawn – Lay down some tarp or plastic sheeting to cover a wide radius around your home. You don’t want bleach spilling onto your lawn and killing your plants.
  2. Make a Bleach Solution – Combine one part chlorine bleach with three parts water in a two-gallon bucket. Mix in one tablespoon of trisodium phosphate.
  3. Apply the Solution – Pour some solution into a handheld pump sprayer and apply it to the shingles that have visible growth.
  4. Rinse – Let it soak for 15 minutes or longer if the growth is severe. Use a low-pressure water hose to rinse the shingles starting from the top.
  5. Inspect – While still wearing your gloves, swipe your hands across the shingles to feel for any remaining slimy residue. If necessary, you can apply the cleanser again, let it sit for 10 more minutes and then rinse again. Never rinse shingles with a pressure washer because it can strip them of their water resistance, which will make your mold problem even worse.

If algae and mold growth persist, then you need to consult a roofing specialist. A professional can help you determine if your shingles need replacing. Check out our guide for determining when it’s time to invest in a new roof.
