Roof Cleaning

Call Us For Your Free Estamate!!

Your roof is exposed to the elements all day, every day. Dirt and debris will collect on it. Natural rainfall is typically enough to wash off the appearance of most dirt. However, the dark stains and green areas that appear on your roof are caused by other natural elements:  Algae, Fungus/Lichen, Moss.

 

How Can Stains Damage a Roof?

The stains and growth patches caused by algae, fungus and moss can damage your roof through shingle deterioration and wood rot. Both lead to expensive repairs and can shorten the life of your roof. A roof cleaning can help minimize or eliminate this damage.

 

Shingle Damage

 

As mentioned above, GM algae is a bacterium that feeds off of both asphalt and limestone. That means that these organisms are literally eating away at your shingles. Furthermore, according to ARMA, roofs with algae stains absorb heat. This results in an extremely high heat in the attic, which can reduce the lifespan of the shingles by essentially baking them from the inside out.

 

Lichen colonies can be quite damaging to shingles. The penetrating tentacles create pock marks where they grow and eventually ruin the shingles.

 

Moss is even more detrimental to roof shingles. Moss can cause the edges of the shingles to lift or curl—often,the first sign that a roof replacement is needed. And because moss holds in moisture, it can freeze in the winter, causing even more shingle damage.

 

Our roof treatment involves spraying the roof with a special solution that will kill the fungus, moss, and lichen; then it will come off from wind and rain the reason we don't try and rine or wash them off is, so we don't damage the asphalt shingle with pressure.
