Commercial Roof Cleaning Services
Protect Your Roofing Asset. Preserve Building Integrity.
For commercial properties, the roof is a critical capital asset — not just a covering. Algae, moss, lichen, and environmental buildup do more than affect appearance. They trap moisture, accelerate material deterioration, and can shorten the lifespan of your roofing system.
What Commercial Roof Cleaning Removes
Professional roof cleaning eliminates:
- Black streaks caused by Gloeocapsa Magma algae
- Moss growth
- Lichen colonies
- Organic debris accumulation
- Atmospheric pollution buildup
- Bacteria feeding on limestone filler in shingles
Black streaking is not surface dirt — it is living algae that feeds on roofing materials. Left untreated, it accelerates granule loss and premature aging.
Commercial Roof Cleaning Options
1. Soft Wash Roof Treatment
This low-pressure chemical treatment is the preferred method for asphalt shingle and many commercial roofing systems.
We apply a professional-grade cleaning solution using controlled, low-pressure equipment — never high pressure — to:
- Kill algae and moss at the root
- Break down lichen growth
- Neutralize organic buildup
- Allow natural rinsing over time
Why Soft Washing Is Critical for Commercial Properties
High-pressure washing on shingles or certain membrane systems can:
- Strip protective granules
- Void manufacturer warranties
- Damage roofing edges and seams
- Force water beneath shingles or flashing
- Reduce overall roof lifespan
Most major roofing manufacturers recommend low-pressure chemical treatment only.
Benefits of Commercial Soft Wash Treatment
- Preserves roofing integrity
- Maintains warranty compliance
- Extends roof lifespan
- Reduces moisture retention
- Protects long-term capital investment
- More cost-effective than premature roof replacement
For property managers, preventative cleaning helps delay costly re-roofing projects.
2. Targeted Moss Removal (For Heavy Growth)
For buildings with significant moss buildup — especially shaded multi-family or northern exposures — additional remediation may be required.
This may include:
- Controlled manual moss removal
- Targeted moss treatment
- Follow-up soft wash application
Benefits
- Immediate visual improvement
- Reduces moisture retention
- Enhances building presentation
Important Considerations for Commercial Roofs
- Moss roots can embed into shingles
- Removal may reveal underlying damage
- Older roofing systems may be more vulnerable
- Severely deteriorated areas may require repair
We coordinate with facility managers to assess risk and provide clear recommendations before proceeding.

Industry Knowledge for Property Managers
Why Algae Grows on Commercial Roofs
Modern shingles and certain roofing materials contain limestone filler, which algae feed on. Flat roofs and north-facing slopes retain moisture longer, increasing growth risk.
Commercial properties near trees, industrial zones, or high humidity areas are especially susceptible.
Moss vs. Algae vs. Lichen
Hot water improves cleaning performance by:
- Algae – Causes black streaking and gradual material breakdown
- Moss – Retains moisture and can lift shingles or seams
- Lichen – Root-like structures that penetrate roofing surfaces
Each requires a specific treatment strategy.
Preventative Maintenance & Asset Management
Routine roof cleaning:
- Extends service life
- Protects insulation systems
- Maintains drainage flow
- Preserves building aesthetics
- Supports preventative maintenance programs
- Helps meet facility inspection standards
Most commercial roofs benefit from inspection and cleaning every 3–5 years depending on exposure and climate.
Safety & Site Protection
Commercial roof cleaning requires strict safety compliance. We:
- Follow ladder and fall-protection protocols
- Use controlled metering systems
- Protect landscaping and surrounding surfaces
- Safeguard gutters and drainage system
- Coordinate with facility operations
We are fully insured and experienced in working on commercial properties.
