Professional Roof Soft Washing

Those black streaks on your roof aren't just ugly — they're Gloeocapsa magma, an algae that feeds on the limestone filler in your shingles. Left untreated, it accelerates roof deterioration.

Our soft wash roof cleaning kills algae, moss, and lichen at the root using a low-pressure, shingle-safe cleaning solution — no high-pressure water that can void your roof warranty or knock granules loose.

The Right Method

Soft Washing vs. Pressure Washing

When it comes to your roof, the method matters. Here's why we never use high pressure on shingles.

Avoid This

✕ High-Pressure Roof Washing

  • Blasts protective granules off shingles
  • Voids most roofing manufacturer warranties
  • Forces water under shingles — causes leaks and rot
  • Doesn't kill algae at the root — it grows back faster
  • Can crack, break, or loosen shingles
Our Method

✓ Soft Wash Roof Cleaning

  • Preserves your roof warranty — no damage risk
  • Specialized solution kills algae, moss & lichen at the root
  • Results last 3–5x longer than pressure washing
  • Safe for asphalt shingles, tile, metal & slate roofs

What's On Your Roof

We Eliminate Every Roof Contaminant

Black Streak Algae

Gloeocapsa magma — the bacteria causing those dark streaks. It feeds on limestone filler in shingles and spreads quickly across entire roofs. Our soft wash kills it at the root instead of just rinsing the surface.

Moss

Moss holds moisture against your shingles 24/7. Over time, it lifts shingles, traps water, and causes rot. We kill the moss and gently rinse it away without scraping or damaging the shingle surface.

Lichen

Lichen is the toughest roof contaminant — a composite organism that anchors deep into shingle pores. Our specialized cleaning agents break it down chemically so it releases cleanly with a low-pressure rinse.

Our Approach

How We Soft Wash Your Roof

Step 01

Protect Your Property

We cover and wet down all plants, shrubs, and landscaping around your home. Downspouts are redirected to prevent runoff into gardens.

Step 02

Apply Cleaning Solution

A biodegradable, shingle-safe cleaning agent is applied at low pressure. It penetrates algae, moss, and lichen at the root level.

Step 03

Dwell & Activate

The solution sits on your roof long enough to kill all organic growth — then we rinse gently with low-pressure water, protecting your shingles.

Step 04

Final Inspection

We walk the property to confirm every streak and patch is gone. Your roof will look dramatically better — often looking nearly new.

FAQ

Roof Soft Washing Questions

Will soft washing void my roof warranty?

No — soft washing is the method recommended by most major roofing manufacturers. High-pressure washing is what typically voids warranties because it blows granules off shingles. Our low-pressure soft wash method preserves your warranty and is safe for all asphalt shingle roofs.

How long do the results last?

With proper soft washing that kills algae at the root, results typically last 3–5 years. Compare that to pressure washing alone, which may leave the root structure intact — algae can grow back in as little as 6–12 months. We recommend a roof inspection every 2–3 years to catch regrowth early.

Are the chemicals safe for my plants and landscaping?

Yes. We use biodegradable, eco-friendly cleaning solutions. Before applying, we thoroughly wet down all vegetation around your home — the water acts as a barrier. After the roof wash, we rinse all plantings again. In many years of service, we've never had a single instance of plant damage.

My roof is only a few years old — does it need cleaning?

If you're seeing black streaks, yes. The age of your roof doesn't determine whether algae grows — environmental conditions do. In Tennessee's humid climate, algae can appear on roofs as young as 2–3 years. Early treatment prevents the problem from getting worse and extends your roof's service life.

Can you clean metal or tile roofs?

Absolutely. Our soft wash method is safe for all roofing materials — asphalt shingles, metal, tile, slate, cedar shake, and synthetic roofing. We adjust the cleaning solution and application for each material type. Metal and tile roofs especially benefit from soft washing to remove oxidation and staining without scratching.

How much does roof soft washing cost?

Pricing depends on your roof's size, pitch, accessibility, and the extent of growth. Single-story ranch homes are typically more affordable than steep two-story roofs. Every project starts with a free, no-obligation estimate — we'll assess your roof and give you an exact price before any work begins.
