Frequently Asked Questions

​​​​​​​​​​​​​​​​Why use softwashing vs. pressure washing? 

Softwashing utilizes low-pressure SoftWash Systems methods with non-damaging, eco-friendly, 100% biodegradable cleaning solutions for your exterior cleaning needs. The use of our professional grade, low-pressure applications maximizes the treatment value and is the ONLY process recommendedby ARMA (Asphalt Roofing Manufacturers Association) and GAF (North Americas largest shingle manufacturer). Softwashing is a technique that treats the infection and lets the cleaning SOLUTIONS sanitize, doing 100% of the work, killing all mildew, algae and lichens at the root, not just the surface, creating a longer lasting clean.  No damaging pressure, harsh chemicals or heat are needed and uses 1/3 the water than pressure washing! Softwashing is better for your home, family and the environment.  

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 will void roof warranties and should never be used for regular maintenance! We want to kill the mildew, algae and lichens from the ROOT. Pressure washing only blasts off the top layer on the surface, spreading the algae spores and penetrating them more deeply into the surface.  This creates more of a problem in the future and will make mold grow back faster!  

What are the stains on my roof, does it cause damage?
Your roof is not just “dirty” it’s infested with bacteria.  The streaks are the bacteria 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.  Don’t wait to replace, save thousands by softwashing! 

Infested, dirty roofs with mildew, algae and lichens can cause numerous problems for you and your family: 

  • Higher Utility Bills:
    • ​Studies prove darker roofs with these bacteria cause your roof to absorb heat, making your home work harder and cost more money to cool in the summer. Excess heat will also dry out your shingles, causing them to crack faster!
  • Unsightly Curb Appeal:
    • Ugly roof stains cosmetically bring down the appeal and value of your property and will cause concern when going to sell your home. HGTV reports the roof is an important curb appeal item and if it's dingy or streaked a good cleaning is necessary.  
  • Increased Allergies:
    • ​Having all that bacteria fester on your roof and exterior create an increase in allergic reactions for people who are sensitive to these types of bacteria. 
  • Lesser Life Span of Roof, Meaning Replacement Sooner:
    • ​Your roof and exterior are one of the biggest investments of having a house; 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, the best solution is to clean and kill all the bacteria on your home! Don't put your family at risk! Hear more!

Is the cleaning solution safe for my family, home and pets? 
Yes! All solutions are eco-friendly and 100% biodegradable.  We ask that during cleaning your family and pets stay inside, but will make accommodations if you need to leave.  We will also do everything to protect your plants, landscaping and property.  All plants are wet down before and during the SoftWash process and after a plant solution is applied with fertilizers and nutrients to complete the process.

How much does it cost to have my roof cleaned?

Many factors are taken into consideration when giving a quote; pitch of roof, square footage, overhang, attached garage, degree of black stains, nearby landscaping, accessibility, water pressure, etc.  Call for a prompt, free, no hassle written estimate.

Do you offer partial cleaning on roofs or exterior?

Yes! We understand there may be areas that are affected more than others.  However it is highly recommended to avoid partial cleaning.  The other areas still may have bacteria and algae spores that can travel to the treated roof sections and re-grow.  Because of this, we do not offer the 5 Year “Spot Free” Limited Warranty on partial cleanings. 

​Do you clean more than just roofs?

Yes! We can provide beautiful results on all residential and commercial buildings; including any siding types, fences, decks, concrete, gutters, playgrounds and just about any other exterior surface.  See all the Services we provide.

Is there a guarantee or warranty for my roof cleaning?

Yes! We use proprietary solutions guaranteed to remove those ugly roof stains the day of cleaning.  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. 

Is the 5 Year "Spot Free" Limited Warranty transferable? 
Yes! We will provide information on how to transfer warranty on your contract if you sell your home within the 5 years.   

Are you trained, certified and insured?
