Yes, bacterial colonies feed on the limestone, hold moisture and cause premature aging, and rotting of the shingles.
Roof washing is the process of removing organic material contaminants from roof shingles or tiles by applying cleaning detergents and low pressure.
The most common chemicals used in roof washing are sodium hypochlorite, also known as bleach, and soap. Bleach kills most all stain-causing organic material while the soap keeps the cleaning solution wet longer allowing it to work for longer.
