What are Those Dark Stains on my Roof?

The discoloration on your roof is caused by harmful bacteria (gloeocapsa magma is probably the most prevalent of several algae) feeding on your roofing surface, specifically the limestone found in asphalt shingles.  Ultimately decomposing your roof and giving an unsightly curb appeal! 

The longer and darker the streaks, the more damage to your roof.  This erosion and granular loss on the shingle cause it to weaken, discolor, harden and crack.  The ending result is a shorter life span for your roof, including: 

  • Higher Utility Bills
    • Bacteria cause your roof to absorb heat, making your home work harder and cost more money to cool. 
  • Unsightly Curb Appeal
    • Ugly roof stains cosmetically bring down the appeal and value of your property.
  • Increased Allergies
    • ​Bacteria create an increase in allergic reactions for people who are sensitive to these types of bacteria.  
  • Lesser Life Span of Roof, Meaning Replacement Sooner
    • ​Mildew, algae and lichens feed on organic material and can grow on any surface.  When they feed they break down the material, which decomposes and needs replacement sooner.  
  • Insurance Companies Can Even Drop Your Coverage
    • ​Insurance companies have been reported to warn and even drop coverage for roofs that are extremely dirty.  Don't put your family at risk! Hear more!

5 Year Spot Free Limited Warranty

We use proprietary solutions to remove those ugly roof stains.  Our process provides a 100% kill ratio on mildew, algae and lichens.  This method kills the roots and inhibits return of growth, therefore we offer a 5 Year Spot Free Limited Warranty  with a complete roof cleaning.  You can also transfer warranty on your contract if you sell your home within the 5 years.    

NEVER Pressure Wash Your Roof

Pressure washing uses high force inches away from the surface damaging the shingles by blasting off the top granular layer and further decomposing your shingle.  This can void roof warranties and should never be used for regular maintenance!  


Our low-pressure, non-damaging, technology and 100% biodegradable cleaning solutions treat all bacteria infestation on your roof.  Mildew, algae, moss and lichens feed away at your shingles, further decomposing them.  Add years back to the lifespan of your roof and receive SoftWash Systems 5 Yr.
