Roof moss and mould spray treatment
Gentle & Effective

Roof Moss & Mould Spray Treatment

Roof moss and mould spray treatment is a gentle alternative to roof washing. It requires no water blasting or pressure cleaning at all. The biocide treatment acts slowly to kill moss, mould and lichen, which is then washed away naturally by rain, leaving your roof clean within 6 months.

In many cases the treatment can be applied from the side of the roof by ladder or even from the ground, meaning our technician does not always need to walk on your roof. With years of experience, we will find the best solution for your specific roof.

Common Questions

Roof Cleaning FAQs

Roof washing removes dirt, debris, moss, mould, algae and lichen. It maintains your roof's appearance, prevents structural damage caused by organic growth, and can improve energy efficiency.

Generally every 2 to 3 years is recommended. Homes in humid, shaded or high-rainfall environments such as many parts of Wellington, Auckland and Queenstown may benefit from more frequent cleaning.

Roof washing uses a low-pressure soft-wash technique to immediately remove moss, mould and algae. Moss spray treatment applies a biocide that slowly kills growth over 6 months, washed away naturally by rain. Both are effective and the right choice depends on your roof's condition.

No. Metro uses soft-wash techniques calibrated to the specific roof material, whether tiles, iron, asphalt shingles or membrane. High-pressure blasting is never used directly on roofing materials.

Yes. Metro uses biodegradable, eco-friendly cleaning solutions that are safe for plants, pets and surrounding waterways when applied correctly by our trained technicians.

Yes. Moss and algae hold moisture against your roofing material, accelerating deterioration and leading to water ingress. Regular cleaning removes these organisms before they cause lasting damage.

Most residential roofs take between 2 and 6 hours depending on size, pitch and the extent of moss or mould growth. Larger commercial roofs may take longer.

Absolutely. A clean, well-maintained roof significantly improves curb appeal and is often flagged positively in property valuations and pre-sale inspections.
