Why Moss and Mould Treatment Matters

Neglecting your roof’s surface can lead to costly repairs and potential health hazards. Regular treatment helps:

  • Prevent damage to roofing materials caused by moss and lichen growth that can break down concrete tiles, clay tiles, and shingles.
  • Protect your roof’s structure by avoiding cracks and leaks caused by trapped moisture.
  • Improve water quality for properties using tank water by removing harmful algae and grime.
  • Preserve exterior surfaces by eliminating damp spots where lichen thrives.
  • Increase the roof’s lifespan, saving you from expensive replacements.

A moss and mould-free roof ensures your property remains safe, visually appealing, and structurally sound. At RBSnz, we provide reliable moss and mould treatment to keep your roof clean, protected, and free from potential damage.

Common Moss and Mould Treatment Tasks

Effective moss and mould treatment involves addressing various problem areas to prevent further growth and damage. Key tasks include:

  • Roof cleaning to remove moss, lichen, and algae that accumulate on tiles, shingles, and other surfaces.
  • Applying roof treatments with a biodegradable solution that kills moss, mould, and lichen while being safe for plants.
  • Washing down the roof using a spray hose to break up grime and debris.
  • Using natural cleansing actions to prevent new moss and mould from taking hold.
  • Trimming overhanging plants that provide shade and encourage damp conditions.

At RBSnz, we offer expert moss and mould treatment to keep your roof clean and protected. Safety is a top priority during every job. We use ladders, safety ropes, and proper protective gear to ensure all moss and mould treatments are completed securely.

Frequently Asked Questions

How often should moss and mould treatment be performed?

We recommend scheduling moss and mould treatment every 2 years to remove moss, algae, and lichen before they cause damage.

 

If your roof is in a damp or shaded area, more frequent treatments may be necessary to prevent growth.

 

Regular treatments not only help maintain the roof’s structure but also protect the exterior surface from stains and grime, while addressing any roof leak repairs to prevent
further damage.

 

This proactive approach can extend the lifespan of roofing materials like concrete tiles and clay tiles, keeping your roof clean and in good condition.

Is the treatment safe for plants and water tanks?

Yes, we use bio-degradable solutions that are safe for plants and water tanks. Our products remove moss, mould, and grime without harming the environment, making them ideal for properties using tank water.

 

The treatment’s natural cleansing action effectively breaks down moss and lichen while protecting nearby plants from chemical exposure.

 

Additionally, we ensure that runoff is controlled to avoid any impact on your garden or surrounding areas.

What roofing materials do you treat?

Our services cover a variety of roofing materials, including concrete tiles and clay tiles for tiled roof restoration, as well as steel roofs and shingles for metal roof restoration.

 

Each material requires a unique solution, and we ensure the appropriate treatment is applied for lasting results.

 

Our roof treatments are also suitable for both residential and commercial use, providing effective protection and maintenance for any property.

How do you ensure safety during roof work?

Safety is our top priority. Our team uses safety ropes, ladders, and protective gear to prevent accidents and minimise damage to your roof. We follow strict protocols to ensure every job is completed securely and efficiently.

 

For smaller areas, treatment typically takes between 1 to 3 hours, but larger areas may take longer, depending on the size and complexity of the job. We ensure all safety measures are in place to complete the process securely and efficiently.

What happens if moss and lichen return after treatment?

Our treatments are designed to provide long-lasting protection. However, if new moss, mould, or lichen growth appears due to environmental conditions, follow-up treatments are needed to keep your roof surface clean and protected.

 

Regular roof maintenance can help minimise the chances of regrowth by addressing underlying causes like damp areas or debris build-up.

 

Additionally, we can recommend preventative measures to further protect your roof’s structure and maintain its appearance.
