We took these photos before we got started and want to explain the importance of roof eradication. What you’re seeing is often roof algae, and while it may start out looking like nothing more than an ugly stain, it can be the beginning of a much bigger problem.
🦠 Roof algae feeds on the limestone filler found in many asphalt shingles. As it establishes itself, it can contribute to the breakdown of the shingle surface and create an environment where moss, lichen, and other organic growth can take hold.
Over time, that growth can contribute to:
• Premature shingle deterioration
• Loss of the protective surface of the shingle
• Moisture retention
• Granule loss
• Reduced overall roof lifespan
At Black Diamond Pro Wash, we don’t just clean what you can see — we focus on addressing the organic growth that is contributing to the problem.
