Moss growth on your roof isn’t just an eyesore—it’s a signal that your roof might be holding moisture in ways that could shorten its lifespan. If you’re a homeowner in Lexington, KY, spotting green or black patches means it’s time to take action. Here’s why trusting a roofing professional is the smartest, safest approach.
Key Takeaways
- Moss traps moisture, leading to rot, shingle damage, and a reduced life
- DIY moss removal can damage roofing materials and void warranties
- Professional roofers use proper tools, safety equipment, and non-damaging solutions
- Lexington’s climate contributes to rapid plant growth, especially on shaded or north-facing roofs
- Barrier Roofs offers free inspections and expert roof maintenance options in Central Kentucky
Why Does Moss Grow on Asphalt Shingles Roofs in Kentucky?
Lexington’s humid climate and seasonal rain make it easy for moss, algae, and lichen, and algae growth to thrive—especially on shaded roofs. Debris from nearby trees, particularly overhanging branches, can trap moisture on the roof surface, further encouraging moss growth.
North-facing slopes are most vulnerable, where the sun doesn’t dry moisture quickly. Moss roots itself under roof shingles, lifting them and allowing water to penetrate. This can cause rot, leaks, and expensive damage if left unchecked.
Why You Should Never Pressure Wash a Mossy Roof
High-pressure water may seem like a quick fix, but it does more harm than good. Pressure washing strips granules off asphalt shingles, weakens their integrity, and can force water under the roof deck. Plus, it often voids manufacturer warranties, including those from Owens Corning.
Improper cleaning methods can also damage professionally installed roof components, reducing the lifespan and effectiveness of your roofing system.
Instead of blasting away moss, professionals use low-pressure chemical treatments specifically designed for roof materials. Barrier Roofs uses industry-approved solutions that kill moss and algae without damaging shingles. After treatment, a garden hose is often used to gently rinse away dead moss and cleaning solutions without harming the roof.
What Roofers Do Differently (and Why It Matters)
Licensed roofing contractors and experienced roofers know how to safely navigate steep slopes and delicate shingles. Here’s what sets professionals apart:
- Safe access: Fall protection gear, harnesses, and ladder safety
- Gentle removal: Soft-bristle brushing techniques for loosening moss without tearing shingles
- Preventive treatment: Application of algaecide or zinc-based sprays to stop regrowth
- Warranty awareness: Methods that comply with roofing manufacturer guidelines and protect the entire roofing system
During moss removal and roof inspections, professionals also check critical features like the chimney, vents, and skylights for signs of leaks or deterioration. They inspect chimneys for structural issues such as cracked bricks, missing mortar, and water damage, and look for cracks in various roof components to prevent leaks and further damage. They assess attic ventilation to ensure proper airflow, helping to prevent future moss growth, moisture issues, and related problems.

The Risks of DIY Moss Removal
Scraping with household tools or applying store-bought bleach can damage your roof and pose health hazards. Chlorine-based cleaners often harm landscaping and degrade shingle materials. Inexperience with height and roof slope also increases the risk of personal injury. DIYers may also miss small issues or minor repairs that, if left unaddressed, can lead to bigger problems down the line.
With professional help, you get peace of mind knowing the job’s done right—no guesswork, no shortcuts. Professionals are trained to identify potential problems before they escalate, helping to prevent costly repairs in the future. They also remove other debris, such as leaves and branches, and look for other signs of roof issues to prevent damage before it occurs.
How Moss Removal Supports Roof Longevity
Moss might seem like a cosmetic problem, but it directly affects your roof’s durability. Removing it improves:
- Water runoff: Unclogs channels that direct rain to your gutters
- Ventilation: Prevents moisture buildup that affects attic airflow
- Curb appeal: Maintains home value and neighborhood standards
- Energy efficiency: Prevents shaded areas from trapping heat and moisture
Regular maintenance and inspections are essential for maintaining your roof’s condition, preventing water intrusion and water damage, and extending the roof’s life. By extending the durability of your roof, moss removal helps prevent premature wear and damage.
Maintaining your roof through regular maintenance, such as moss removal and inspections, is crucial for preserving the roof condition and can extend your roof’s life span by years.

FAQs About Roof Moss Removal in Lexington
How often should I inspect my roof for moss?
Regular inspections are recommended—at least annually, or after particularly wet seasons. Spring and fall are great times to assess your roof’s condition for moss and other kinds of damage.
Can moss damage my shingles?
Yes. Moss holds the damp and can lift shingles, leading to leaks and decay underneath. It can also create damaged areas and result in missing shingles.
Will moss come back after removal?
Not if preventive treatments are applied. Professional-grade algaecides can stop regrowth for months or even years.
How much does professional moss removal cost?
It depends on your roof’s size and condition, but Barrier Roofs offers free inspections and clear, upfront quotes.
Is moss removal covered by homeowners insurance?
Not usually, unless moss contributed to a covered damage event. We offer insurance claim support if needed.
How does winter weather affect my roof?
Heavy snow accumulation and freezing temperatures can lead to the formation of ice dams, which occur when melting snow refreezes at the roof’s edge. Ice dams can cause water to back up under shingles, leading to leaks and damage to your roof, gutters, and even walls.
What roofing materials are best for preventing moss and weather damage?
Tile roofs are a durable option that can withstand the elements, including heavy rain, snow, and wind. Along with tile, materials like metal and slate are also effective at resisting moss growth and weather-related damage, helping to extend your roof’s life and reduce maintenance needs.
