So Why Do I Have Things Growing On My Roof?

For something to live it needs two things, food and water.

Water comes easy between rain and morning dew. On the South side of your house, the surfaces are exposed to a constant exposure to the sun so it dries fairly quick. The North side of your house however doesn’t see too much direct sunlight so it tends to take a lot longer to dry. There are other factors as well such as trees that block the sunlight. So these shaded areas will allow enough moisture to hang around to support life.

But where is the food source??? Here is a hint, it’s your shingles!!! Your shingles contain limestone which is a great food source. So all of that stuff you see up there is literally eating your roof.

Roof Cleaning

These dark spots were once lichen that were feeding on the shingles.

Our low pressure roof cleaning process kills the organisms that grow on your roof.  Never use a pressure washer as it will remove the granules from your roof as well.   Results aren’t always immediate but are guaranteed.  Once we apply the cleaning agents we allow it to dwell on your roof.   We leave the rest up to Mother Nature.  Rain and wind will carry the dried up, dead material off of your roof.

Don’t wait! Don’t allow your roof to be fed upon by unsightly organisms.  The longer they dwell on your roof the more damage that they will do.  Call Wagner Window Service to clean your roof with low pressure to prevent any more damage to your roof.
