Cedar Roof Cleaning Professional NJ

Thanks for stopping by! You’ve found a company that provides the niche service of cedar roof cleaning. Cedar roofs should never be cleaned using high pressure. The debate on the 2 schools of thought drags on as to either apply sodium percarbonate and follow up with a low-pressure power wash or the alternative sanitizing process for organic staining.

Pressure washing creates a challenge since you need to be above the shingle in order to pressure wash downward.  In most case a lift is required which in turn adds further expense. Continual use of aggressive high pressure can cause damage to the the cedar shake. Most stains contain organic features that react well to properly proportioned detergent. A cedar roof shingle infested with algae or mold will retain moisture and rot prematurely.

Roof cleaning is not a “power washing” job. Learn more about roof cleaning in this video Cedar Roof Cleaning Video. Our reps are also available to discuss price and process.

Cedar Roof Cleaning Treatment

Your roofs infestation can be corrected with a mild detergent that contains a sanitizing feature. After application with a short dwell time the roof can be rinsed and must remain long enough to dissolve the mold. Most detergents with a sanitizing feature can have aggressive properties and should not be used frequently. Long term use of aggressive detergents can break down the fibers of the shingle therefore this process should not exceed 5 applications over the life of a cedar roof.

Mold and rot are doing the real damage allowing the shingle to retain moisture.  It can become soft and fail so it remains paramount to keep the shingle clean of mold, moss and algae. Visit our other cedar roof cleaning page here Cedar Roof Cleaning

Each full roof treatment comes with our 3 Year Spot-Free Warranty.  Completely sterilizing the roof yields a clean roof for many years where as a spot-treatments allow stains to regenerate faster.

Moss and Lichens

Removing moss and lichen requires patience since the first treatment applied simply kills the growth at the root level. Like any other type of plant or fungus it will die and decompose before washing away with a few rains. It can take up to a year in severe cases yet most cases of moss clear up yet in most cases its less than 90 days. The amount of rain sessions may affect the length required to fall away.

Removing heavy moss instantly will require aggressive agitating such as stiff scrubbing or pressure washing with an aggressive pressure.  Considering the growth is a living organism a pest-control approach can insure the roof remains free of stains for an extended period of time. Aiming for top sterilization ani sure a clean surface for an extended period of time.
