How to clean slate roof tiles

If you have a slate roof, it’s important to keep it clean and well-maintained. Dirt and debris on your roof can cause water to pool and seep into your walls and ceiling, leading to mold and costly repairs. To effectively clean your slate roof, you will need a bucket, a squeegee or scrubber, a hose, a ladder or scaffolding, gloves, and a slate cleaning solution.

Follow these steps to clean your slate roof:

  1. Remove any loose debris from the roof using a broom or hose.
  2. Fill a bucket with warm water and a small amount of detergent or slate cleaning solution. Mix well.
  3. Apply the cleaning solution to the roof, starting at the bottom and working your way up. Scrub gently.

  4. Rinse the roof thoroughly with a hose, removing all the cleaning solution.
  5. Inspect the roof for any missed spots or stubborn stains, and repeat the process as needed.

Tips to ensure a safe cleaning process include using a ladder or scaffolding, wearing gloves, avoiding abrasive cleaners or pressure washers, and testing the cleaning solution on a small area before applying it to the entire surface. It’s best to clean your slate roof once a year or as needed to prevent damage and maintain its appearance.
