Roof Cleaning

Darien’s #1 Roof Cleaning

Your Roof Is Being Eaten Alive

Those black streaks aren’t just ugly—they’re destroying your most expensive asset.

Every day you wait, they’re causing permanent damage that will cost you thousands to repair.

Every homeowner in Darien Knows This Feeling

You’re driving up to your beautiful property, and those dark streaks running down your roof make your entire home look neglected and old.

But here’s what you probably don’t know: Those streaks are Gloeocapsa Magma algae, and they’re feeding on your shingles right now.

Every day you wait, they’re causing permanent damage that will cost you thousands to repair.

The Hidden Damage Happening Right Now

Here’s the uncomfortable truth about those dark streaks:

That’s not dirt. It’s a living organism called Gloeocapsa Magma that literally consumes the limestone filler in your asphalt shingles. As it feeds, it:

  • Strips away protective granules (your shingles’ armor)
  • Retains heat (increasing your cooling costs by up to 25%)
  • Accelerates aging (cutting your roof’s life by 5-10 years)
  • Spreads aggressively (doubling its coverage area each season)
  • Damages curb appeal (reducing home value by $50,000-$100,000)

 

The math is brutal: A $100,000 roof that should last 25 years might need replacement in 15 years.

Benefits of Maintenance vs Replacement

Why Pressure Washing Will Destroy Your Roof

Most contractors will pressure wash your roof. Here’s why that’s catastrophic:

Immediate Destruction:

  • Granule stripping – High pressure literally sandblasts off the protective layer
  • Forced water infiltration – Water gets driven under shingles, creating leaks
  • Seal damage – Tears apart flashing and weatherproofing
  • Structural stress – Can crack or break brittle shingles

Financial Consequences:

  • Warranty void – Manufacturers specifically prohibit pressure washing
  • Insurance issues – Claims denied for “improper maintenance”
  • Premature replacement – What should be a $1,000 cleaning becomes a $20,000 roof

We’ve documented dozens of roofs destroyed by pressure washing. Don’t become another casualty.

The result? A Damaged Roof

(This 6 year old Architectural Shingle Ridge Cap (with a 30 year Manufacturer’s Warranty) was caused by a power washer “washing” the roof.)

Our Manufacturer-Approved Soft Wash Process

We use the ONLY method recommended by Owens Corning, GAF, and CertainTeed:

Phase 1: Comprehensive Assessment & Protection Complete roof inspection, property protection setup, safety system deployment, and customized chemistry selection.

Phase 2: Precision Soft Wash Application Biodegradable cleaning solution applied at garden hose pressure only (never exceeds 100 PSI vs pressure washing’s 3000+ PSI).

Phase 3: Scientific Dwell Process Chemistry does the work – solution penetrates and kills organisms at root level with no mechanical agitation.

Phase 4: Professional Completion Low-pressure rinse when needed, complete site cleanup, gutter cleaning included, and full documentation provided.

The result: Your roof looks new, your warranty stays intact, and you add years to its lifespan.
