Key Biscayne's roofs go through distinct cycles over the year, and timing your roof cleaning around them gets better, longer-lasting results than cleaning on a random schedule.

The Year on the Island

Rainy-season algae growth on a Key Biscayne roof

Rainy Season (May–Oct)

Frequent rain with heat and humidity creates ideal conditions for algae and moss growth, particularly on shaded, north-facing sections that don't fully dry between rain events.

Dry-season deep roof cleaning window in Key Biscayne

Dry Season (Nov–Apr)

Lower rainfall means slower algae regrowth, making dry season a practical window for a deeper roof cleaning — results hold longer before the next rainy season resets the cycle.

Year-round salt air exposure on a Key Biscayne roof

Year-Round Salt Air

Unlike seasonal algae growth, salt air exposure is constant, steadily wearing down roofing sealant and shingle granules regardless of season.

Best Time to Schedule Roof Cleaning

For most Key Biscayne properties, scheduling a thorough roof cleaning near the start of dry season sets up cleaner, longer-lasting results. A second cleaning partway through the rainy season helps control algae buildup before it sets in deeply.
