What's Included in Our Gentle Roof Cleaning Service
Those dark black streaks on your roof are not dirt or soot—they are caused by a hardy cyanobacteria called Gloeocapsa magma (black algae) that feeds on the limestone filler in asphalt shingles. Left untreated, algae and moss trap moisture against your roof, leading to shingle deterioration, wood rot, and higher cooling costs.
Our professional roof soft washing service includes:
Extends Roof Lifespan
Clears away destructive organisms before they weaken shingle bonds or cause premature shingle replacement.
Removes Black Streaks
Eliminates unsightly dark algae stains to restore your roof's original color.
Prevents Moss & Lichen Damage
Kills root systems that lift shingle edges and trap damaging moisture underneath.
No High Pressure Used
Applied entirely with soft-wash pressure levels under 100 PSI to preserve shingle granules and comply with roof manufacturer standards.

Rated 5 Stars Across Northern Virginia & The DMV
"Used them to wash 4 commercial center's roofs, sidewalks, and awnings. Professional service, diligent work, and easy to setup. Highly recommend!"
"Their three-man crew worked hard for three straight days, and it truly shows. Our walkways, steps, retaining walls, and common areas look cleaner than they have in years… They were professional, courteous, and respectful of both residents and the landscaping throughout the project. I would not hesitate to recommend them to other communities looking for quality power washing services."
"Great job transforming a gray and faded IPE wood deck into almost like new condition. Easy to work with and reasonably priced! Highly recommend."
Why High-Pressure Washing Ruins Roofs
High-pressure water should never be used on a roof. Our soft-washing process relies on specialized cleaning solutions—not physical water pressure—to kill algae at the root safely.
Strips Protective Granules
High pressure blasts away the ceramic granules embedded in asphalt shingles. These granules are essential for shielding your home from UV rays and fire hazards.
Voids Manufacturer Warranties
Major shingle manufacturers explicitly state that power washing a roof voids your warranty coverage.
Forces Water Under Shingles
Powerful water streams can lift shingle edges and force moisture into your attic and wooden roof deck.
Our Step-by-Step Roof Cleaning Process
Safety & Property Setup
We secure all safety gear, inspect roof pitch and condition, and cover or divert downspouts if needed.
Plant Protection Pre-Rinse
We thoroughly saturate surrounding landscaping and garden beds with fresh water to shield foliage.
Low-Pressure Detergent Application
We apply our ARMA-compliant soft-wash detergent mix across the entire roof surface at low pressure.
Dwell Time & Algae Neutralization
The solution sits to destroy black algae, moss, and lichen spores at the root level.
Fresh-Water Rinse & Final Walkthrough
We complete a gentle rinse and soak surrounding plants once more, leaving your roof clean and your yard pristine.
Complete Exterior Pressure Washing in Arlington, VA
Pressure Washing
We use high-pressure water streams to blast away deep dirt, clay, and grime from durable outdoor surfaces. It is ideal for restoring concrete sidewalks, brick walls, and solid stone structures.
Power Washing
Power washing uses heated, high-pressure water to dissolve heavy oil, grease, gum, and ground-in dirt. Our trucks carry built-in hot-water systems designed specifically for tough driveway stains and commercial surfaces.
Soft Washing
High water pressure can crack siding and force water behind your walls. Soft washing uses gentle low pressure combined with mild, plant-safe soaps to kill mold, mildew, and green algae on vinyl, stucco, and wood siding safely.
Window Cleaning
Clean, clear windows instantly brighten your home. We clear away dirt, hard water spots, and pollen from exterior glass surfaces for a spot-free finish.
Hardscape Cleaning
Stone patios, brick walkways, and paver driveways lose color over time. Our specialized crews deep-clean your hardscapes to remove dirt, grime, algae, and organic buildup while restoring a cleaner, refreshed appearance.
Gutter Cleaning
Heavy tree cover across Arlington leads to clogged gutters. We clear leaves and organic debris to ensure proper water drainage and protect your home's foundation from costly water damage.
Commercial Services
We help Arlington businesses, retail spaces, apartment complexes, and HOA communities maintain clean, inviting exteriors. We offer flexible scheduling to keep your property looking great without interrupting business hours.
