Roof Mold

Believe it or not...Insurance policies being cancelled because of ROOF MOLD. Watch these videos.

Watch our own video!

This is a normal pitched roof. We are able to do much steeper roofs than this. If you have a steep roof no problem. We stand on a ladder and shoot our cleaner up onto the roof. Our cleaner soaks into the mold and kills the mold while it literally lifts it up off the shingles so we can rinse it away into the gutters.  

Gutters are then flushed out. 2 storey houses, no problem. 

We are able to do up to 4 - 6 storey houses. Call us for a FREE ESTIMATE.

He spray it on the roof mold but instead of the roof mold dissapearing he dissapears.

PLEASE, take our advice and close the door on them. They are trying to fraud you.

     You may wonder why a pressure washing company would offer roof cleaning when you know that shingles shouldn’t be pressure washed. The answer is our "NO PRESSURE" soft wash system, WE DO NOT PRESSURE WASH ROOFS. When cleaning a shingled roof, you have to apply the "NO PRESSURE" soft wash cleaning system as if it's a light rain or you will damage the shingles. Pressure washing a roof will take 7 years off the life of your shingle per two independent home inspectors office's here in Crossville and should NEVER EVER be done that way. Our soft wash system only delivers a spray and is very very light so it doesn't remove any granules. We never use HIGH pressure on roof shingles. The only safe roof cleaning is a our "NO PRESSURE" soft wash cleaning system. Many folks are confused between pressure and power washing and they don't even know their roof can be cleaned. Roofs can be cleaned with generally a "NO PRESSURE" soft wash and produces results that look like a new roof. If your roof looks darker or green in some areas it defiantly needs cleaning. Here in Tennessee there is a lot of black streaks on roofs, this is roof mold. Removing it will last for some time. We use SCRUBBING BUBBLES which is 100% BIO-DEGRADABLE so that it is safe to all animals and plants and is PROPRIETARY to Pressure Pro Power Washing. We have cleaned roofs 3 or 4 years ago and they still look like the day we did it. So give us a call or click FREE ESTIMATE to fill out the contact form and we would be glad to see what you need done.

What HOME INSPECTORS say about this video.

We recently visited several home inspection offices here in the Crossville

area and showed them this video. They say even though this might not

seem harmful, it is indeed VERY harmful and it will take 7 years off the

life of the shingles. The slightest amount of pressure loosens the granules

and if they are not removed with this application the regular rain will

remove them and eventually you will have to replace your shingles sooner

than later. They suggest when cleaning a roof to use a no pressure system

so no granules are loosen. They say the no pressure system is the  safest

way and best way to clean a roof WITHOUT damaging the shingles in

any way.  OUR PROFESSIONAL OPINION: In this video you

can see just straight high pressure water is being used. No

cleaner seems to be present which means that later down the

road there will be nothing there to prevent it from coming

back. You must have a cleaner left over so it soaks into the

limestone and doesn't come back. Even if a cleaner was

applied before hand this technique shows that you are

washing the cleaner away and it doesn't have time to soak into the limestone. You should NEVER EVER wash it away. The cleaner is specifically designed to do all the work and lift the mold off of the shingles and go down the rain spout. It will then crystallize into the limestone and help prevent it from coming back. If it's not done correctly you may see it coming back months after it has been cleaned. PROFESSIONAL ROOF CLEANERS DOES NOT USE PRESSURE OF ANY KIND. (just common sense)

Pressure Pro Power Washing

NEVER EVER uses pressure to remove roof mold.


proprietary to us. We want the customers

investmet to be safe from any damage.

3 or 5 Year Written Warrenty


The 3 or 5 year warranty is covered if you have ALL mold removed from your roof the very first time. Let's say all sides of your roof         has mold. If you only want the front side cleaned and not the back side cleaned it is a good possibility it will return before the 3 or 5 years. This is an air born mold so we have to kill ALL OF IT and not part of it. If ALL the mold is removed we can feel comfortable to give you a 3 or 5 year warranty. It works that well. Our written warranty is located on your receipt we give you after the roof is cleaned. Other companies or "handy man" in our area does roof mold removal by PRESSURE or CHEMICAL and they say you get a warranty but do you really? If it is a verbal warranty, you have NO WARRANTY. Don't be stupid. Warranty is only good if you have it writing and has their information on that warranty.

Selling your house? This is why you should have your roof cleaned before hand.


If you are going to sell your house or even want someone to come out and tell you what your house is worth you need to have the roof cleaned first because if you think about it the roof mold will devalue your home. Today it cost between $2500 to $10,000 to replace a roof. If a prospective home buyer comes to see your home and see's the roof mold on it the very first thing he or she will say is that it's gonna cost this much to replace the roof so I will offer that amount of money less. It's a lot cheaper to have it cleaned than replacing a new roof so this is why you should always have a clean roof before you try and sell or put a value of your property. It's only common sense.

How much does it cost?


We are asked this question all the time on the phone or someone ask about it away from the location of the roof mold. The best answer I can give is that it depends how many directions the roof mold is on and how bad it is. We can say it's pennies compared to the $50,000 investment you own. It would cost a fraction of replacing a new roof that is up to $10,000 just cause you have A LOT of roof mold. We also only charge you for roof mold on your roof that is facing one direction. If you have roof mold facing 2 directions we charge for 2 sides. Most roof mold is facing 2 directions but sometimes on a 3rd or 4th side. If you have roof mold and it's only on 2 side there is a highly likelihood that it wont ever grow on those other 2 sides. The way we do this is for instance...if you have roof mold facing the west side of the roof and you have 3 or 4 different roofs facing the west side you are only being charged for one side. No matter how many different roofs you have facing one direction that would be considered as one side. We do this because the mold is usually on front and back of house cause those roofs are facing the same direction and we want to kill all of the roof mold and not just half of it. We dont charge for the front of house and back because not all directions are effected and dont need to be treated. It forces us to do ALL roofs instead of just the front or the back of the house. Best thing is to give us a call and let us give you a FREE ESTIMATE. It only takes about 15 minutes to talk to you and explain everything we know about it so you understand fully what is involved.

50% Of Roofs Are Replaced Due To The Way They Look. 


This is not because of their functionality. Half of the roofs ever replaced in the South East didn't need to be replaced, only cleaned. Just as mold and mildew can grow on your vinyl siding, wind blown algae can land and grow on your roof. Replacing your roof because of this algae is like replacing your siding instead of having it cleaned; it just doesn't make sense. Some roofing contractors don't know what these black streaks are, saying it's the asphalt showing through the shingles or that it's water stains. Some contractors may know it's algae but tell you it can't be cleaned without damaging the shingles. In either case, they may tell you that the roof needs replaced. This is not true if your shingles are still in good shape. The algae can be killed and removed properly without damaging the shingles using a soft wash application (recommended by shingle manufacturers). Never use a high pressure on an asphalt shingle roof, doing so will blow granules off the shingles and lessen the longevity of your roof. 

Our Process


    A stained roof can make your entire house look unappealing but Pressure Pro Power Washing can make it look like new in just a few hours, and keep it that way for several years. The soft wash process is approved by the Asphalt Shingle Manufacturers’ Association  ARMA as well as GAF a leading shingle manufacturer. We strictly follow the guide lines laid out and recommended by ARMA (Asphalt Roof Manufacturers Association) and major shingle manufacturers like GAF and Owens Corning. Pressure Pro Power Washing "NO PRESSURE" soft-wash system has successfully cleaned 100's of roofs in Cumberland County and surrounding counties and across America more than 50,000 roofs has been cleaned using our same exact system that only PROFESSIONAL roof cleaners use.


The safe, environmentally friendly soft wash process uses a NO PRESSURE, biodegradable cleaning solution to eliminate the algae

from your roof and prevent it from coming back. We do add 1% bleach to our mix which is also BIO-DEGRADABLE to help kill any fungus that is on the roof. (1% Bleach is a half bottle in a 50 gallon mix) No damaging power wash. No expensive shingle replacement. Just a great looking, longer lasting roof that you can be proud of.


The soft wash process can clean virtually any type of roof, including asphalt, tile, slate, metal and cedar.


Video below shows you how NOT to have your roof cleaned.

This degrades the shingles and takes away 

7 years of life away from your shingles. 



Here’s how it works:

  1. Inspect: Our technicians will perform a complete visual inspection of your roof’s exterior. They’ll notify you of any visible structural issues and photograph them for your records.

  2. Pr-treat: Before the full application, we’ll apply a coat of cleaner to the most severely stained areas of your roof. This gives the cleaner additional time to work where it’s needed most before we apply the full application.

  3. Clean & Restore: Next, we’ll apply a generous coat of cleaner to your entire roof. An even coat will ensure that every inch of your roof’s surface gets cleaned. During this stage, 99.9% of existing algae and bacteria will be removed from your roof.

The soft wash process takes 2-4 hours and in most cases, your roof will be completely clean and algae free by the time we leave. You don’t need to be home during the application; we only ask that you keep pets inside, close all doors and windows, and ensure that there’s a working outdoor water source such as a hose connection.

What is roof stains?


    Roof stains are caused by algae called Gloeocapsa Magma. All it takes is for one algae spore to land on your shingle and it will continue to multiply and spread. Its growth is fed by the limestone filler in the shingles and moisture. In years past, the algae simply didn't have a food source. This changed with the introduction of fiberglass shingles during the past 20 years. The fiberglass shingles made today contain massive amounts of food that the algae loves to eat, that food being limestone. How in the world does limestone get into fiberglass shingles you might ask? It's simple. The limestone is added to the asphalt mixture as a filler or thickener. Years ago, this was not necessary, as an organic felt mat was used as the base for the shingles. This mat was saturated with asphalt and then coated with granules. Granules are tough, dense, ceramic-coated rock which protects the roof from the sunlight and weather. Because of the absorptive qualities of the mat, it was able to soak up enough asphalt to give the finished shingle sufficient weight. Well, about 20 years ago, this rag market dried up because of the widespread introduction of synthetic textiles, such as nylon and polyester. The shingle manufacturers scrambled and decided to use fiberglass as a mat. However, a problem quickly arose. The thin fiberglass mat didn't absorb asphalt like the old organic mat. Something had to be added to the asphalt to increase the weight of the shingle. They decided to use limestone which is plentiful and cheap. 

Green moss on your roof (video) 


If you have greem moss on the roof most home owners would replace

the shingles. No need to replace shingle when you call us. We have a

cleaner we spray on moss that will instantly kill it and turn it a

white-yellowish color. In fact most home owner is amazed at how

much moss they really have because they can't really see the small

patches of the dark green moss because the shingles camouflage the

moss. Once we spray our cleaner on the live moss you can definatly

see it turn to a white-yellowish color. This is the first sign of it being

dead. In most cases we ask the home owner to let mother nature

takes it coarse and let it fall off the roof. Since it is dead it wont stay

there very long. The rain and wind will blow it away. This way no

pressure is put to the shingles keeping your shingles in good shape. 

Places most likely to see Roof Mold


   As you can see on the map right below the state of Tennessee is in the dark green area. This is HIGH ALGAE GROWTH because of the

high humidity.

Algea Resistant Shingles


   In recent years, roofing manufacturers have begun mixing copper granules into roofing products to produce algae resistant shingles. If you live in an area susceptible to algae growth, be sure to specify this type of shingle when replacing your roof.

$$$ out of your pocket!


   Roof mold is proven to increase your electric bill in the summer. Your electric bill could be as high as 10 - 20% higher than if you did not have roof mold. The roof mold growth holds the water on the roofs surface so when the sun comes out the water acts as a magnifying glass which produces more heat. It then prevents the heat to escape in return the air conditioner runs much longer than it should. Here we talk about your savings.


   If a Customer has a 2,500 square foot home. The roof square footage is actually 3,000 square feet. Let’s say for demonstration purposes the cleaning will cost $600.00 and the customer has a $250.00 a month electric bill. Let’s assume that 5 months out of the year the customer runs their A.C. Finally lets use a 20% post cleaning savings to be super conservative.


$250.00 Electric Bill (20%) = $50.00 Savings / Month

$50.00 Savings / Month (5 months) = $250.00 Savings / Year

Roof Stays Clean 3 Years…

$250.00 Savings / Year (3 Years) = $750.00 Total Savings

$750.00 Total Savings - $600.00 Roof Cleaning = $150.00 Profit.

Additional Prevention


   To keep algae from coming back once your roof is clean, install a

strip of copper or zinc coated sheet metal along each side of the roof

just below the ridge. To be effective, 2”- 4” of metal should be visible

on the roof. While copper is 10 times more toxic to algae, galvanized

sheet metal is much less expensive. Both copper and galvanized

metal are available in rolls of various widths and thickness online and from us at Pressure Pro Power Washing. We also will install this if you like. You can also purchase zinc strips specifically made to eliminate roof algae. Narrow strips of sheet metal can be attached directly to your roof using roofing nails or screws with a rubber washer. For wider pieces of sheet metal, loosen the self-sealing tabs on the top row of shingles with a putty knife, slip part of the sheet metal under them, and nail it in place under the shingles with roofing nails.The methods used to eliminate and prevent algae on your roof can also be applied to moss.

As you can imagine Mrs. Henderson

was very pleased with the outcome.

She said it looked better than it

did for the last 12 years.

Give us a call and I'm sure you

will be pleased too of the outcome.

Specifics: What's Growing On Your Roof?
Addressing The "Growing" Problems On Roofs Caused By Algae, Lichen, Fungus, and Moss.













Algae, or Gloeocapsa Magma, can spread... from one infested roof to another via the release of airborne spores. As more homes are built closer together, this hardy algae has been able to spread rapidly.

Algae is well adapted to extreme conditions... heat, long dry spells, UV rays, heavy rain, intense cold, thick snow or high winds doesn't deter it. 

The dark color of Algae is a pigmented protective sheath... that encapsulates each cell to protect it from UV rays 

Copper and Zinc can both inhibit algae growth... Zinc (including pellets) however does have other inherent problems, such as: it's limited ability to be color matched to roofing shingles, attachment method to roofing shingles, cost and the occasional "bloom" effect due to the build-up of zinc oxide. Copper granules are used instead of zinc for these reasons. 

Copper is 10 times more effective against algae than Zinc... Zinc actually becomes less effective against algae quicker than copper 

Shingles at work…some granules covering the shingle contain Copper encapsulated by a specially developed coating allowing Copper (cupric ions) to be time-released to prevent algae over a long period 

Dew is the dominant source of water for algae and is the "agent" best suited for the release of the copper in Algae Resistant shingles. Rainwater, although effective, runs off a roof too quickly to provide significant leaching of copper. Dew is also present more days than rain. 

Algae can go for long periods of time without water... It is unaffected by heat or downpours and is dormant in winter. Algae secretes a material that adheres them firmly to the shingle surface. 

Algae is killed immediately by copper. FACT: Algae cells are poisoned over time. 

Algae is a fungus. FACT: Algae, or Gloeocapsa Magma belongs to the Cyanobacteria branch in the Eubacteria family and is not a fungus.

Installing a copper ridge or hip shingle with copper granules on an existing roof may overcome an existing colony of algae.

FACT: Granules have not been proven to kill existing algae.

Are fungus resistant shingles better?: FACT: "FR" is an inaccurate name since fungus is not the actual source of the suggested problem. Additionally, copper granules have not been proven to inhibit fungus growth
