If you’ve noticed dark streaks or greenish patches on your roof, you’re likely dealing with algae growth—a common problem in warm, humid climates like Texas. It’s not just cosmetic. Left untreated, algae can damage your roofing materials and reduce your home’s value.

At Bright & Shiny Window Cleaning & Pressure Washing, we recommend soft washing to safely eliminate algae and extend the life of your roof. Here's why it matters.

🧪 What Is Algae, and Why Does It Grow on Roofs?

The culprit behind those black streaks is usually Gloeocapsa magma, a type of blue-green algae that feeds on the limestone filler in asphalt shingles.

Algae thrives in:

• Warm, humid conditions
• Shaded roof sections
• Areas with tree cover or debris buildup

Over time, it holds moisture and promotes the growth of mold, lichen, and moss—damaging the integrity of your roof.

🏠 How Algae Harms Your Roof

Algae isn’t just an eyesore—it can:

• Cause shingle deterioration
• Increase cooling costs by reducing reflectivity
• Lead to premature roof aging
• Reduce property value and curb appeal

Routine roof maintenance, especially with soft washing, can stop this damage before it worsens.

💦 Why Soft Washing Is the Best Solution

Unlike high-pressure methods, soft washing:

• Uses low-pressure water
• Applies biodegradable, algae-killing cleaners
• Gently removes buildup without damaging shingles
• Is recommended by most roofing manufacturers

At Bright & Shiny, we use soft washing to clean thoroughly without voiding your roof warranty.
