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.

Superior Exterior only uses 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 not 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 so-called "low" pressure and biodegradable chemicals 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 insures the shingle's warranty. The roof will no longer have the original 20-30 year warranty the customer paid for. Thousands of dollars are spent each year replacing and repairing damage caused by under skilled operators and companies who over sold their knowledge and capabilities. 

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.

We offer a 3-5 year warranty against any streaks reappearing on your shingles.
Depending on environmental conditions against algae regrowth on your roof, the angle the roof faces the sun, the pitch, color, shade and tree cover the roof has, will determine how long the roof will remain streak, mold and mildew free. The more humid and warmer the climate, the more favorable the growing conditions for algae are, thus the warranty period is shorter than in colder, drier climates."

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. If the roof does not have gutters we will thoroughly dilute the roof cleaning chemical down to safe levels by spraying the landscaping with water before, during, and after applying chemical. 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 guarantee our roof cleaning will outlast our competitors!
