Roof Cleaning Services in Randolph, NJ

As you drive down the road you begin to notice black streaks on roofs. You think to yourself, this is new, what could this be from? In most cases, homeowners are unaware of the hazardous growth occurring on their roof. This growth is a bacterium, algae to be specific. You might have noticed over the past few years the increase of humidity around our areas during the summer. This bacteria feeds off moisture and calcium carbonate and creates a UV protected shell which creates the black streaks. Today’s shingles are made from fiberglass with asphalt which holds limestone inside as filler. Limestone is made up of calcium carbonate which allows for this airborne bacterium to grow on your shingles and therefore start its eroding process.

Without cleaning your roof, this erosion gets worse over time. Stage 1 is initial growth in which bacterium has settled into shingles and starts discoloring the roof. Stage 2, the feed process, is when the bacterium multiplies and green patches form; finally in stage 3, you have a small forest growing on your roof. The good news is, Burrini’s & Sons Power Washing can quickly get rid of this growth at any stage. We deal with all types of roofs, including asphalt, tile, and metal. It’s best to do the entire roof so that growth does not return or continue on un-cleaned areas. Give us a call to get your roof clean again in no time.
