How to Remove Roof Stains: The Easy Solution

Roof Stains

You might not be able to see it, but that sheen that looks like mold on your roof is actually algae growth. Algae feed off of moisture and the limestone filler agents in shingles. The algae growth can quickly form and spread on your roof, leading to unsightly algae stains. If left untreated, algae can cause damage to your roofing materials and compromise your roof's integrity.

Plain water isn't effective in removing roof algae. Algicide is a safe and effective roof cleaning product that will kill roof algae and prevent them from coming back. Algicide is available in a variety of formulations, so be sure to read the label and choose the right product for your needs.

Before you start removing stains, be sure you check weather conditions and pick a calm day to work. Next, hire a roofing contractor to repair any loose or missing shingles. Then make sure your gutters are clean and free of debris. This will help keep water from pooling on your roof and allow it to drain properly. Finally, you can begin your roof cleaning process.

  • Safety harness
  • Scrub brush

Trimming
