Roof Cleaning Fairfax VA

No Pressure Roof Cleaning Fairfax VAIncludes a 3 year warranty!

Don’t replace that roof just yet. It CAN be cleaned! Chances are if you look around your neighborhood you will see roof stain streaking. Often thought of as tree sap or jet fuel, the unsightly streaking is actually organic matter. In some cases you will not only have streaking, you will also have moss and lichen. Whether you are just starting to notice the dirty roof or received a letter from the HOA, we can take that ugly roof and transform it to a like-new roof!

Where it grows:

You know the saying “If you ever get lost in the woods and need to find your way, moss grows on the north side of the rock?”. Well the same is true for roofing. Whichever side of your home faces north is guaranteed to have the most algae because the bacteria needs moisture and shade in order to live. In addition if you live in a heavily wooded area or have trees providing excess shade on certain parts of your home, that can also speed up growth. Of course, northern Virginia weather can make an impact as well. Eventually, the black streaks can dominate a roof. It doesn’t matter what manufacture makes the shingle, the color or the location.

Types of Roof Algae:

  • Black algae streaking (Gleocapsa Magma) is unsightly and can make your roof look older than it is. It is an algae that feeds on the crushed limestone in the shingle granule. It is not tree sap, jet fuel etc.
  • Moss is the three dimensional green fuzzy “blooms”. This type is particularly harmful because it can wedge itself in between the shingles and cause lifting.
  • Lichen is usually flat and in a light green or tan color.
