Roof Cleaning Tauranga (Treatment & Washing)

What’s the difference between roof treatment and roof washing?

Roof treatment targets moss, mould and lichen at the root using a low-pressure application, while roof washing removes surface build-up. In most cases, Roof Treatment Tauranga provides a longer-lasting and safer result.

Do you offer roof washing?

Yes. We provide Roof Washing Tauranga using controlled, low-pressure methods where appropriate to safely remove build-up.

Do you use high-pressure cleaning on roofs?

No. High-pressure cleaning can damage roofing materials and force water under the roof. We use controlled, low-pressure methods designed to protect the roof.

When is roof washing recommended?

Roof washing may be used for:

  • Preparing a roof for painting
  • Removing heavy build-up
  • Specific maintenance requirements

Our team will recommend whether roof washing or roof treatment is the best option.

How does roof treatment work?

Our Roof Treatment Tauranga service applies a low-pressure treatment that kills moss, mould and lichen at the root. Rain then gradually removes the dead growth over time.

How long does roof treatment take to work?

You’ll usually see improvement within a few weeks, with full results developing over several months.

Do you walk on the roof?

Most treatments are applied from the gutter line, so walking on the roof is usually not required.

Is roof cleaning safe for all roof types?

Yes. Our methods are suitable for most roof types including concrete tile, metal, Coloursteel, Decramastic and clay tiles.

How often should roof treatment be done?

Most homes benefit from treatment every 2–3 years depending on environment and exposure.

Pre-Paint Washing Tauranga

Why is pre-paint washing important?

Pre-paint washing removes dirt, mould and contaminants that can prevent paint from adhering properly. Learn more about our Pre-Paint House Washing Tauranga service.

Do I need to wash my house before painting?

What does pre-paint washing include?
  • Cleaning exterior walls and cladding
  • Removing mould and contaminants
  • Washing under eaves and gutters
  • Rinsing surfaces ready for painting

This ensures surfaces are fully prepared for painting.

Do you work with painters or contractors?

Yes. We regularly coordinate with painters and contractors to ensure surfaces are properly prepared and ready for painting.

Is pre-paint washing different from a standard house wash?

Yes. It is specifically focused on preparing surfaces for painting and ensuring proper adhesion.
