Fungus and moss are normal growths that can be found on roofs. There is generally a lot of fungus on roofs in spots without humidity; just due to the reason these growths help moisture. The growth of fungus and moss creates the appearance of an ignored roof and can reduce the value or attractiveness of your house. This growth appears as dark streaks and can spread very fast on the roof. They do not injure or damage asphalt shingle roofs, but they are very unsightly and most homeowners eliminate these growths. Cleaning your roof is very dangerous work though and should be performed by a roof cleaning company with a high level of expertise.
Even though roof cleaning services effectively eliminate fungus and moss, they generally return in a few months. It is best to use a power washer to clean the roof. There is an argument whether roof pressure wash cleaning can harm the shingles and cause leaks. However, if performed with good care, a power washing will not ruin a roof. The issue is that plenty of homeowners who decide to pressure wash do not perform it effectively and in a downward motion. This causes the power of the pressure washer to loosen or break shingles. When aimed downward and at a minimum of six inches away from the shingles, roof pressure wash cleaning should not destroy the roof.
Washing the roof with the proper cleaning product and hose is the best choice for safely cleaning the roof. There are large numbers of products on the market particularly designed to eliminate algae stains. Be sure to follow guidelines while using these goods. Prior to cleaning the roof, it is recommended to talk with the manufacturer of the roof if possible, to check whether it has any particular requirements on cleaning.
Oxygen bleach can be used rather than the trisodium phosphate (TSP) mixture. It is popular for lightening stains. Using oxygen bleach generally requires a certain amount of scrubbing, but it is effective for small spots with fungus or moss growth.
