Amazing aesthetic results are not the only reason to have your roof cleaned. The dark stains typically seen on the north face of roofs are cyanobacteria that retain moisture, allowing moss, lichen, mold, and fungus to grow and flourish. This bacteria feeds on the limestone filler in asphalt shingles. Moss and lichen break down the granular surface which is designed to protect asphalt shingles, shortening the service life of your roof.
Pacific Roof Cleaning is proud to be featured as the cover photo of The Roof Cleaning Issue of eClean Magazine. That's right, a whole magazine issue dedicated to roof cleaning, because it's that important! This phenomena is a common site on building exteriors, particularly in areas where there is consistent moisture due to humidity, coastal marine layers, low lying valley fog, etc.
We provide service from Carmel to the entire Bay area from our centrally located base in Santa Cruz. Many times we are able to give accurate estimates within hours through satellite imagery.

The dark shading and staining of roofs, walls, and exterior surfaces in central California is generally due to the cyanobacteria gloeocapsa magma.
Many times, exterior building surfaces are virtually free of all dirt and grime, but the presence of the dark bacteria is clearly evident.
Typical cleaning procedures use power washers to remove the visible stains and dirt.
While valuable for some applications, pressure washing itself does not kill the spores and can be very destructive to many of the most common exterior coatings in use today, including stucco and synthetic stucco such as EIFS and Dryvit.

It is easy to see on most homes while the growth is in the process; there are dark black streaks, particularly on the north-facing roof, though once the algae have fully taken over it is sometimes hard to tell.
The black stains are caused by a cyanobacteria frequently referred to as algae (Gloeocapsa Magma) that feeds on organic material (Typically crushed lime stone) now used in composition roof shingles.
Algae growth on roofs occurs to varying degrees in all regions of the country, especially those subjected to warm humid conditions.

Pacific Roof Cleaning specializes in non-pressure, manufacturer-approved roof cleaning.
Many cleaning contractors like to use the term "Soft Wash" but their process includes using a pressure washer.
We never use pressure.
As an experienced building contractor and certified roof inspector, we have seen the consistent damage this causes, even by highly experienced professionals.
Our "Soft Wash" process produces immediate results that last four to six times longer than pressure washing.
As far as the results, we let our real customer testimonials, non-manipulated before and after photos, and years of proven success speak for themselves.
