Lichen Treatment Service

Although it grows slowly, lichen can be extremely damaging over time. It thrives in damp, shaded areas—especially on tiled or metal roofs. Once it takes hold, it traps moisture, which leads to further problems.

• Tile damage: Lichen feeds on minerals in roof tiles, making them brittle and prone to cracking.
• Moisture retention: It creates a moist environment that can lead to mould and wood rot underneath.
• Structural issues: Damaged tiles increase the risk of leaks, water stains, and interior ceiling damage.

Because of these risks, it’s crucial to act early and schedule a professional lichen removal from the roof before the damage worsens.

Not sure if it’s time for lichen treatment? Here are signs to look for:

• Thick patches of grey, green, or yellow growth on your roof tiles
• Debris buildup like twigs and leaves holding in moisture
• Water stains on ceilings (a possible sign of leaking from underneath, lichen growth)
• Older roofs or homes surrounded by tall trees and shade

If you spot any of these, don’t wait. The longer you delay, the more costly the repairs may become. Our trained team knows exactly how to remove lichen from roof without causing additional damage.

DIY solutions can be dangerous and often ineffective. Walking on a tiled roof is risky, and harsh chemicals can damage roofing material or harm surrounding plants. Instead, professional treatment is both safer and more effective.

At JK Gutter Cleaning, we use Wet & Forget—a biodegradable product with a pH of 8. It’s free of bleach, acid, or strong fumes, making it ideal for safe roof cleaning. Most importantly, it continues working long after it’s applied.

1. Assessment – We inspect your roof’s material, slope, and condition.
2. Spot Treatment – We apply Wet & Forget directly to heavy growth areas, then reapply across the full roof surface.
3. No Rinsing or Scrubbing Needed – The product activates with rain over time, naturally killing the lichen without the need for harsh pressure washing.
4. Eco-Safe Cleanup – We take care to protect nearby plants and leave your property clean and tidy.

We don’t just clean gutters—we understand the science of roof care. With years of experience in roof lichen removal, we know which treatments are safe, effective, and appropriate for your specific roof type.

Our cleaning methods are gentle yet powerful. We avoid bleach, pressure washing, or abrasive tools that might compromise tile integrity. Plus, our product is safe for surrounding gardens and wildlife.

We proudly serve clients throughout Sydney and the Gold Coast, offering reliable service with honest advice. Our work speaks for itself, and customer satisfaction is always our priority.

We also offer:

• Gutter cleaning to remove debris that causes lichen
• Maintenance plans to prevent regrowth
• Reports and photo documentation for insurance or property upkeep

This all-in-one approach ensures long-term protection and peace of mind.

Lichen can return over time, especially in humid or shaded environments. However, with the right steps, you can drastically reduce the chance of regrowth.

This allows sunlight to dry your roof naturally, making it less inviting to lichen spores.

Blocked gutters trap moisture, which encourages lichen growth. We include gutter debris removal and inspection with every service.

Depending on the environment, we may recommend reapplying the treatment every 12–24 months. This is especially useful for homes near coastal or forested areas.

Preventive care always costs less than repairs. Our maintenance plans help you stay ahead of lichen and other threats.
