  • Mix the hot water, bleach, and detergent and pour it into a sprayer.
  • Spray the solution on a portion of and let it stay there for about 15 min.
  • Use a broom to scrub the wet area of the roof.
  • Keep the roof portion wet until scrubbing goes on, if the cleaner begins to dry out, spray a bit more.
  • Rinse the cleaned section with fresh water, and repeat the process until the roof is clean. :thumbsup:

Great information!

We also clean roofs and paint. Here in hot humid Tampa FL rainy season the roof algae grows very quickly. Our painting and roof cleaning company has been battling the dark black roof stains that appear on the north side of roofs here in Tampa for many years!

Many times the stains require a second 'shot' of solution like the one you mentioned. Western Central Florida Roof Stains get jet black...with all of the rain and moisture.

Many of the house painters in Tampa use the same solution to clean dark algae stains from stucco like the ones pictured in the linked page.

Have a safe day!

First apply algaecide to the roof that neutraling the algae growth.For smaller surface areas a good rinse down of all adjacent structures. However, for larger roof cleaning projects, periodic rinse and wet downs are the best way to protect and care for the property.

Roof cleaning in different season is really very complicated. Even though you have good experience. In winter when ice thumbed at roof. It really very embarrassing to hire unprofessional for your roof cleaning service. So you should have better experience for roof cleaning services.

When you use bleach, make sure to bag off all gutter downspouts. It's not a bad idea to have a guy spraying down plants close to house with water while you are treating roof.
