Roof Cleaning
What you should know about cleaning your roof. DON'T REPLACE IT, CLEAN IT!!
Your house is most likely your biggest investment and your roof is one of the most expensive parts of your house. It is extremely important to have the utmost in confidence in your decision before hiring a qualified roof cleaning contractor.
ROOF CLEANING PRO / PRESSURE WASHING PRO only use chemicals approved by the ARMA* Asphalt Roofing Manufacturers Association and does not use pressure on your shingles. We also provide our customers with technical bulletins directly from Asphaltroofing.org and shingle manufacturers to prove that our procedures and chemicals are properly formulated for roof cleaning. Our chemicals provide enough cleaning power to remove all mold, mildew, and streaks...without pressure washing or heavy rinsing. We 100% guarantee your roof will look brand new.
Pressure washing is never recommended because it will remove a large amount of the ceramic coated granules from your shingles, which will void the warranty. Even low pressure will cause granule loss and shorten the life of your shingles. If you have ever cleaned out the inside of your gutters you will notice granules in them just from the rain taking them off. Think what any additional pressure would do to your roof. For instance, you see someone cleaning a roof with pressure and it appears they have done a good job just because the streaks and discoloration are gone, but guess what? So is a large amount of the protective ceramic coated granules which insure your shingle's warranty. Nobody wants to replace a prematurely failed roof due to an incompetent roof cleaning contractor, and you shouldn't have to.
We offer a 3 year warranty against any streaks reappearing on your shingles.

Always use a 'chemical only' cleaning process for your roof. Roof cleaning is a completely different trade from pressure washing requiring different pumps, plumbing, hoses, nozzles, valves, chemicals, caution, knowledge, experience, skill, and insurance. PWPRO has all of the necessary tools, and have learned from the best roof cleaning professionals in the country.
Make sure you know what kind of chemicals are being applied on your property. Do not accept "it's biodegradable" for an answer. Even uranium is biodegradable over 50,000 years or so.
Because many "competitors" lack our roof cleaning equipment, knowledge, training, and experience, they sometimes apply a dangerously strong chemical solution. Sodium Hydroxide and Potassium Hydroxide will dissolve the asphalt and tar on your roof, shortening the life of your shingles and voiding the roof's warranty. Even sodium metasilicate is too corrosive.
Our chemicals do all of the work to remove streaks and discoloration from your roof and require no pressure or heavy rinsing. Because we do not have to rinse, your roof will stay cleaner longer than our competitors. Leaving the chemicals on the roof creates a roof treatment or a hostile environment for future algae growth. Each time it rains, a small amount of chemical is washed off to help re-clean your roof over and over again.
Concerned about your plants, pets, and landscaping?
We only spray the roof, not your plants. We always bag the ends of your downspouts, collect all the chemical run-off from the roof and dispose of them away from your landscaping. After the chemical biodegrades and evaporates from the roof, the dried crystals and surfactant act as a roof treatment to keep the roof cleaner longer as it rains.
The rain actually does a better job of rinsing than if you tried to rinse it yourself because the rain is slightly acidic with of ph of 5.6. Our roof cleaning chemical has a ph of 11 and most city water supplies have a ph of 8. The rain helps reactivate the chemical at a lower ph, which gives the roof a secondary cleaning, neutralizes the chemicals better, and aids in disinfecting the mold and mildew embedded in the shingles even further. The rain does a much more thorough job, giving your roof a much longer lasting cleaning.
We have had to go behind many competitors who use chemicals NOT approved by the ARMA or shingle manufacturers or use no chemicals and pressure wash or rinse their customers roofs, which start growing mold and streaks after only two years.
We have had to go behind many competitors who pressure wash or rinse their customers roofs, which start growing mold and streaks after only 2 years.
