Blue Sky Power Washing has all the correct insurance including liability and workers compensation.
Blue Sky products used to clean the exterior of your home are biodegradable! Having your roof in Southern New Hampshire cleaned is recognized as general maintenance as it improves the life of your asphalt shingles.
We use a soft wash system in NH & MA, which means that the pressure is similar to that of a garden hose.
The use of high-pressure will not only damage your roof, but it will also void any existing warranty that your roofing materials may have. Many companies claim that their process is "low-pressure" when in fact they are simply "dialing down" the PSI (pounds per square inch) output of their high-pressure units. Another cleaning method you will want to avoid is one that involves the use of an "aluminum disc" also known as a "surface cleaner". This equipment has been designed strictly for hard surfaces such as driveways, walkways, tile floors, etc. A surface cleaner simply rinse away any dirt and debris without killing it. In fact, this method actually spreads the bacteria, which causes your situation to be much worse the following year.
