Black Algae (or blue green algae- Gloeocapsa magma). Commonly found in climates with warm, humid summers, it does no damage to the roofing, but it certainly does looks bad. One costly solution is to replace the roof with copper granule shingles, which repel the algae. An inexpensive way is to soft wash the shingles with a water bleach mixture that brings back the color and kills the algae and mold without destroying the integrity of the roof.

Swampy’s soft wash system will lengthen the life of the roof and save you thousands of dollars in replacement costs. For ceramic tile roofs, Swampy blasts away the mold and algae by utilizing Hydramotions’ Sidewinder rotary surface cleaner. With 3500 psi and 200 degrees of water mold and algae doesn’t have a chance. Results can last up to 2 to 3 times longer than a regular noncommercial cleaning.
