Basics of our No Pressure Roof Cleaning process
At Knipple Powerwash, we are a Maryland based roof cleaning company specializing in
no pressure roof cleaning in Maryland and Delaware.
The Asphalt Roofing Manufacturers Association (ARMA) mandates the proper methods of cleaning
asphault roof shingles.
A NO Pressure roof cleaning solution application is the only method approved for roof cleaning
since any pressurized spray can knock off protective granules or work it's way under the shingles
and get the roofing underlayment wet which can lead to further damage.
Our NO Pressure roof cleaning method is only part of the process. Proper preparation of the
surrounding areas requires presoaking adjacent structures plants and painted surfaces. Recollecting
as much of the solution as possible without structural modification should also be implimented.
After the NO Pressure roof cleaning
For smaller surface areas a good rinse down of all adjacent structures and plants after the roof has
been cleaned is sufficient. However, for larger roof cleaning projects, periodic rinse and wet downs are the
best way to protect and care for the property.
Please note: the solution is left on the roof to
allow the the added algaecide plenty of time to take care of the cause of the roof stains.
When we leave - the stains are gone
The stains will be taken care of with the no pressure roof cleaning process. In the case of moss or lichen,
there will still be some left behind. Moss has a dense little root structure and pulling it off the roof will
cause the most damage. Scraping it off will do a little less damage but will still do harm. It is best to
leave the moss in place and let the roof cleaning solution kill the moss and a good rain will rinse it
off the roof.
Replacing your roof can be very costly. To avoid the expense of a new roof, call us for an estimate
