Black Streaks On Roof? What They Are & How To Remove Them
Black streaks on roofs are extremely common across Massachusetts and Southern New Hampshire.
Many homeowners assume the stains are dirt, but they are actually caused by a bacteria called Gloeocapsa Magma that feeds on the limestone filler in asphalt shingles.
What Causes Black Streaks On Roofs?
The dark streaks you see on roofs are typically caused by roof algae.
Over time this bacteria spreads across shingles and creates the streaking pattern many homeowners notice.
Because New England has humidity, shade, and organic debris, roofs in Massachusetts and Southern NH are especially prone to this problem.
Why You Should Not Pressure Wash a Roof
Many homeowners consider pressure washing when they see roof streaks.
Unfortunately, high pressure can damage shingles and shorten the lifespan of the roof.
Professional roof cleaning uses a soft washing method that safely removes the bacteria without harming the roofing material.
