What are those black stains on my roof? | NJ Roof Cleaning

NJ Professional Roof Cleaning Services

I’ve heard many theories in my career. Some think it’s caused by granule loss, some say it’s jet fuel. It’s actually an algae, Gloeocapsa Magma, that feeds on oraganic matter in your roofing shingle. It is a hardy algae with a rigid husk. It can almost always be found on the north side of the roof where there is less sunlight.

With the proper combination of cleaning agents it can be safely removed. Powerwashing causes damage and can loosen the roofing granules that protects the underlying membrane.

What’s In The Soap?

There is no secret what we’re using.  The roof manufacturer suggest using bleach in any roof detergent concoction.  Bleach and sodium hypochlorite are the same thing.  Bleach is made from sodium chloride (common table salt).  When bleach breaks down and dries what is left is salt.  Put bleach in a bowl and put it outside.  Come back tomorrow and you will see that any chlorination will have evaporated along with any liquid.  What you will find in the bowl is salt crystals.

Bleach is strong yet a safe and truly biodegradable cleaning product.  Sodium hypochlorite is used at a municipal level to treat our drinking water.  It is also the same product used in treating swimming pool water.  This is the perfect soap since all of the stains on the roof are organic such as mold, algae, moss and lichen.
