If you’ve noticed unsightly black streaks or discoloration on your roof, you’re not alone. Many homes across Sanford, NC and surrounding communities like Broadway and Tramway deal with the same issue. But what are these roof stains, and are they more than just an eyesore? Let’s explore the truth about roof stains and how Straight Streamin Pressure Washing can restore your roof to like-new condition.
What Causes Black Roof Stains?
Those dark streaks are typically caused by a type of algae called Gloeocapsa magma. This airborne algae thrives in humid climates like ours in central North Carolina and feeds on the limestone filler in asphalt shingles. Over time, the algae can spread and retain moisture, leading to:
Premature roof aging
Moss growth
Increased energy bills due to reduced roof reflectivity
Why Roof Cleaning Matters
Beyond the visual impact, a dirty roof can cause long-term damage to your shingles. Moisture-retaining algae and moss can lead to rot, granule loss, and leaks. In areas like Carolina Lakes or near Lake Trace, this is especially common due to tree cover and higher humidity.
Soft Washing: The Safe Way to Clean Your Roof
Unlike traditional pressure washing, our soft washing technique uses a low-pressure system combined with eco-friendly cleaning agents that kill algae and lift dirt gently. This prevents shingle damage and ensures a longer-lasting clean.
