Shingle roof cleaning and exterior soft washing project completed. Asphalt shingles require a no pressure detergent application to avoid removing the granules. PEERLESS Roof Cleaners follow all guidelines and recommendations during your cleaning.
The answer is gloeocapsa magma roof algae, also known as black mold. This hearty cyanobacteria thrives in wet humid climates like the Valrico area. The crushed limestone that is used to make your asphalt shingle provides nutrients for the organism. Even AR or algae resistant shingles will become infected with black roof stains.
As the rains accumulate, the algae will begin to work its way around your roof. Starting in the north, you will see small black star burst shaped dots with black streaks coming down. This is how the algae spreads.
The same method you would use to rid weeds of your garden. Using manufacturers guidelines, the proper solution applied with a minimal walking method is used without using high pressure washing. The solution contains sodium hypochlorite and tri-sodium phosphate at proper ratio’s. Our roof cleaning solution Peerless Punch is applied utilizing custom to our specification pumps. Using a pressure washer to remove the stains will remove the heat absorbing granules.
With the proper climate, nutrients and water, unfortunately roof stains will come back again.
The trick is to catch the stains as soon as they appear and not to allow them to populate the entire roof top. Then you are maintaining your shingle roof and not going through a major cleaning every 12 months. The Peerless Punch Roof Cleaning System outlast pressure washing with bleach two to three times. Typically you will see new growth on the north side in 18-24 months.
Keeping your clean shingles free of leaves and debris will help your roof stay free of stains longer. Remember, you only have so many of the heat absorbing granules on the
shingle. Once they are gone or if they are removed prematurely, heat will be able to attack the inner layers of the shingle causing rapid wear and tear.
