Factors like low light, limited airflow, and debris growth can exacerbate the problem. While scrubbing may provide a temporary relief, it’s important to tackle the underlying cause to avoid their return – often involving treating the roof with a fungicide solution or improving attic ventilation.

Remedies range from light pressure cleaning to the use of specialized cleaning chemicals. Professional companies can safely address the issue, ensuring little damage to your roof and preserving its condition.
