Another of our services we specialize in is roof cleaning. We are a Portland Oregon roof cleaner that takes pride in every project, big or small.  There are two types of roof cleanings that we do. The first one we will discuss is the general maintenance roof cleaning. This is simply removing loose debris such as pine needles and leaves from your roof by blowing them off and cleaning them from the ground. The roof debris removed is put into the customer's yard debris bin or for a low price of $5 per large bag removed, we will haul the roof debris away.  When looking for Portland roof cleaners we know price and process is important.  Here are our roof cleaning prices and an explanation of our process.

The following is our minimum charge for a general maintenance roof cleaning:

$75 for all roof debris removed and affected gutters cleaned out. Additional gutters not affected by our cleaning of the roof will be priced accordingly. You can check our prices for gutter cleaning on our gutter page.

Roof (Moss Removal)

Many different companies perform their roof moss removals differently. The following is the ARK way. We have simplified our roof moss removal process as much as possible. We access your roof by ladder and begin by scrubbing the mossoff of your roof by use of brushes (along the affected surface, please see pictures) and brooms. Many other roof cleaners will want to "pressure rinse" your roof and for some types of roofs this is an okay method. However, we never "pressure rinse" a composition roof. If you have a warranty or insurance on your roof, please check it before anyone uses a pressure washer on it because most roof warranties specify that any pressure rinsing of your roof will VOID your roof's warranty.  Please see our pressure washing page for more details on what we will pressure wash.
After removing at lease 90% of the moss off your roof we then blow it off of your roof and/or sweep it off. The gutters are cleaned after this. The same rule follows for the charges on your gutters as with the general maintenance roof cleaning. If you choose the entire moss removal process we tack on a 1 year no-moss guaranty. Please ask for further details at time of your roof cleaning estimate.

The following is our prices for moss removals:
$150 minimum for patches of moss removed from your roof. If there is moss in all of the horizontal and vertical linings of your roof shingles it will be more than the minimum price, but we always try to be fair and honest with our pricing no matter what. 
$50 minimum for Zinc strip removal from your roof. Sorry, we do not install them. They have been tested by the test of time and failed 9 times out of 10.
Every roof cleaning comes with a FREE gutter cleaning for affected gutter lines. Please see gutter cleaning page for gutter pricing of non-affected gutters.
