Those dark streaks are often a type of algae called Gloeocapsa magma, which thrives in the humid, shaded conditions common in our New England climate. It feeds on the limestone filler in asphalt shingles. While it doesn't typically cause immediate structural damage, it can retain moisture and accelerate granule loss, shortening your roof's lifespan. A professional cleaning or treatment can remove it and help protect your roof.

Finding some granules, especially after a new roof is installed, is normal. However, excessive granule loss is a common sign of aging or weathering in our area and should be addressed. Granules protect the asphalt coating on shingles from UV rays. Significant loss can lead to faster deterioration, leaks, and reduced protection. We recommend a professional inspection to determine the cause and whether repair or replacement is needed to safeguard your home.
