At ROOF REAL CLEAN, we have heard a wide variety of explanations for roof black streaks and stains, including ”chimney smoke settling,” “cracked acorns,” “tree sap,” “shingle weathering” and so on. One “creative” roofer even told a homeowner who lived near an airport that the black streaks and stains on her roof were the result of “fuel dropping from the sky.” None of these answers are true. Most roofs in need of a roof cleaning have roof algae growing on them. Black streaking is caused by ’living algae’ known as Gloeocapsa Magma.
Roof staining is a relatively new occurrence. Cutting back your tree or discontinuing the use of your fireplace will not prevent roof black streaks & Stains or correct an existing problem. Algae spores are air-borne and are carried by the wind from house to house. Algae grows in visible colonies when all the right elements are present, including:
- Limestone (Algae food)
- Humidity (Moisture)
Why Some Roofs Have Roof Algae Growth and Others Don’t
The reason that some roofs have roof algae growth in the same neighborhood and some don’t is mainly due to the amount of sunlight hitting the roof. If a roof gets a lot of sun, the colonies burn up. It a roof gets minimum sunlight the colonies are unable to grow. Even the same roof can have some parts with roof algae growth and other parts with no growth at all.
Roof Moss is Dangerous to Your Roof
Roof moss is more dangerous as it will grow beneath the roof shingle, acting like a sponge after a good rain. If roof moss is not removed by a professional roof cleaner, eventually it can break down the shingle and cause roof leaks. Roof moss tends to build up on the North side of a home or where a roof is shaded for most of the day.
Why You Need To a Professional Roof Cleaner
It is important that you have a roof cleaning professional remove roof moss or roof algae if you see it growing on your shingles. Roof algae and roof moss feed on the organic matter contained in your shingle. The growth will break down the asphalt shingle causing the ceramic granules protecting the surface of the shingle to loosen and fall off, which causes the shingle to deteriorate prematurely.
If not treated, roof moss and roof algae growth will reduce the life of your roof, not to mention how unsightly roof streaks and stains diminish your home’s ‘curb appeal.’
