More about Roof Cleaning

​

The black spots and streaks are a form of algae that feed on the limestone filler of your asphalt shingles.   This is an air born algae that can easily move from one roof top to another and quickly cover any neighborhood. Like any algae, best conditions for spreading are wet, humid and shaded areas. Growth normally begins on the north side of structures. These areas generally get more shade and take longer to dry out from nightly dew and rain.

 

We have heard some people say the black stains are only a cosmetic issue and they are not hurting anything, but the truth is, this black alga devours limestone granules that are pressed into the shingles. Eventually, the granules become loosened and you will notice an unusual accumulation of them inside your gutters.

 

The algae holds in moisture on your roof, creating premature aging and cracking of your shingles or tiles, ultimately drastically reducing the life of your roof. Left untreated, those black streaks will spread across your roof causing higher cooling bills and premature damage.

 

Many homeowners mistakenly think that the only way to rid their home of ugly roof stains is to spend thousands of dollars on a new roof. In most cases all they need is a professional Roof Cleaning to make their existing roof look like new again.
