Please recommend a product that will remove dark algae or mold stains from our roof.
Mold Clean should be fine on your fiberglass shingled roof. We would recommend only doing a small area first before doing the whole roof to make sure that you are satisfied with the results. Also, please be aware that Mold Clean will only remove stains and will not kill the mold spores. Please let us know if you have any additional questions.
