Frequently Asked Questions About Moss & Lichen Treatment
How often should I have my roof treated?
Most homes benefit from professional roof lichen treatment in Auckland every 2-3 years, depending on your roof’s exposure and the surrounding environment. Homes with overhanging trees, north-facing slopes, and areas with poor drainage may need more regular treatments to protect their roofs.
During our free evaluation, we’ll assess your specific situation and recommend a maintenance schedule tailored to your roof’s unique conditions and Auckland’s varied climate.
What are the benefits of treating your roof?
Roof treatment offers several benefits for your home, including:
- Extending Your Roof’s Lifespan: Moss and lichen actively damage your roof by retaining moisture and degrading materials. Eliminating these organisms before they cause lasting damage helps avoid premature replacement costs.
- Preventing Water Damage: As moss spreads, it lifts and separates roofing materials, creating entry points for water. Working with roof moss removal companies eliminates existing growth and creates an inhospitable environment for future growth.
- Preserving Roof Materials: Moss, algae, and lichen gradually break down roofing materials, making regular professional treatment essential to stopping this degradation and maintaining a protective roof.
- Restoring Appearance: Organic growth creates dark, unattractive patches that age your home’s appearance. Our thorough roof treatments restore your roof’s original look and enhance your property’s overall curb appeal.
- Protecting Your Investment: Left untreated, moss and lichen damage can lead to expensive repairs or, in more serious cases, early roof replacement. Roof lichen treatment and moss elimination protect your investment and maintain your home’s value.
What’s the difference between a roof wash and treatment?
Roof washing focuses on cleaning surface dirt and debris for an improved appearance, while roof treatment uses specialised solutions to eliminate moss and lichen at the root level.
Washing is a temporary solution—growth returns quickly as root systems remain intact. Our roof moss treatment kills existing organisms and creates a protective barrier to prevent new growth for up to 2 years.
Are your treatment chemicals safe for the environment?
We’re committed to providing biodegradable roof moss treatment in Auckland, reducing harm to the surrounding environment. Using responsible chemicals, we can effectively kill moss and lichen without harming your garden, plants, or surrounding soil.
