Over time, roofs can accumulate dirt, debris, and even algae or moss, which can compromise their appearance and functionality. Regular roof cleaning is essential to maintain its longevity and appearance. However, choosing the right cleaning method and materials is crucial to avoid damage.

There are several methods to clean a roof, each with its own set of advantages and disadvantages. The choice of method may depend on the type of roofing material and the level of cleaning required:
