Roof Cleaning in Mendham NJ
This are not very good pics below, but they will show immediate results of treating the black stains on the roof. These black stains are bacteria and are very contagious. Pressure washing the roof is not an option. Power washing a roof will dislodge large amounts of roofing granules. These granules protect the shingle membrane from the deteriorating effects of the suns UV. If the granules are thinned out the roof will deteriorate faster.
The manufacturer has put out a bulletin addressing the issue of black staining on roofs. They have a written warning about using high pressure to clean roofing shingles. The bacteria which grows on the roof, called Gleocapsa Magma, is protected by a sturdy outer husk which repels against drought and harmful UV rays. This is why this organism can live on the roof even with long periods absent of rain. Pressure washing will only blow live mold spores around the property. Our detergent is designed to penetrate the outer shell of the organism and kill it. We apporach this more like a “pest control job” and we seek a 100% kill ratio. This insures the roof will stay clean for an extended period of time.
