How to Remove Mold From Your Roof


Mold on your roof is not just unsightly; it can also lead to serious damage if left untreated. As a professional contractor serving Rockland County and Westchester County, I've helped many homeowners tackle this issue. Here's a step-by-step guide on how to safely and effectively remove mold from your roof.



Identifying Mold on Your Roof

Mold often appears as black, green, or brown streaks on your shingles. It thrives in damp, shaded areas and can spread quickly if not addressed. Regular inspections, especially after wet seasons, can help you catch mold early.



Steps to Remove Mold

  1. Safety First: Wear protective gear, including gloves, goggles, and a mask. Use a sturdy ladder and take necessary precautions to avoid falls.

  2. Clean the Roof: Use a garden hose with a spray nozzle to gently wash away loose debris and dirt. Avoid using a pressure washer, as it can damage shingles.

  3. Apply a Cleaning Solution: Mix a solution of one part bleach to three parts water. Use a pump sprayer to apply the solution to the moldy areas. Let it sit for about 15-20 minutes.

  4. Scrub Gently: Use a soft-bristle brush to scrub the moldy areas. Be gentle to avoid damaging the shingles.

  5. Rinse Thoroughly: Rinse the roof with clean water to remove any remaining bleach solution and mold.

  6. Prevent Future Mold Growth: Trim overhanging branches to reduce shade, and clean gutters regularly to ensure proper drainage.
