Those black streaks are algae stains, often called Gloeocapsa magma, which thrive in our humid, coastal climate. They feed on limestone filler in asphalt shingles. We don't just power wash them; that can damage shingles. Instead, we use a professional, low-pressure algae treatment that safely removes the stains and applies a preventative solution to inhibit future growth, protecting your roof's lifespan and appearance.

Finding some granules is normal early in a roof's life, but excessive loss is a common sign of wear from our intense sun and weather. It means your shingles' protective layer is degrading. We'll perform a thorough inspection to determine the cause—whether it's aging, storm damage, or improper installation—and advise on the best course of action, from targeted repairs to a full replacement if needed to prevent leaks.

Look for key signs: widespread granule loss, multiple leaks, sagging, or extensive algae that cleaning won't fix. In our area, age is also a major factor; roofs over 15-20 years old are more vulnerable. The best step is to have us conduct a free, detailed inspection. We'll assess the damage specific to your home and provide a clear, honest recommendation on whether repair or replacement is the most cost-effective, long-term solution.
