Roof Cleaning Auckland

Roof cleaning & treatments

Maintaining your roof will protect it from damage and save you costly repair work down the track. An annual roof cleaning or treatment will ensure that unsightly moss, mould and lichen are removed, and that the surface of your roof is restored to looking great again. If left unchecked, contaminants on the roof can penetrate the surface, eventually leading to structural damage that is expensive to fix.

Professional roof cleaning services

At Chemwash Auckland, we offer specialised roof cleaning treatments that are suitable for virtually every type of roof. From Coloursteel, iron, clay and concrete, to chip and decramastic tiles, our professionally trained team have the knowledge and experience to provide a superior roof cleaning service to Auckland households and commercial and retail building owners. Different roofing materials require different cleaning techniques to prevent damage during the cleaning process – Our team can discuss with you the best options suited to your roofing surface when they conduct an on-site visit and provide you with a no-obligation, free quote.

Roof Instant Clean

With Chemwash ‘Instant Cleans’, we fully soft wash your roof surfaces. We apply a combination of industrial-grade biodegradable detergents to the roof surface. These will instantly clean off any dirt and grime along with moss, lichen and mould. It is recommended that NO water pressure be applied to certain types of roofing, such as concrete, slate and terracotta tiles. A safety harness rigging fee will apply when we are instant cleaning.

Moss and Mould Treatment

Chemwash’s industrial-grade Moss & Mould Treatment is biodegradable, environmentally friendly and suitable for all roof types. This aqueous solution activates rapidly when wet, thus giving rapid penetration and killing the moss and mould gradually over a period of time depending on climate conditions. The complete process requires up to several months to process and to see fantastic results.

Our Moss and Mould Treatment is free from unpleasant odours, environmentally safe and has a lasting effect (up to 18months ) on the surface treated without damaging the associated areas being worked on.

Our process is quick, cost-effective and low-mess.

Biodegradable cleaning detergents

Our biodegradable detergents are designed to be safe to use for all households including those on rural tank water supply. They are slow-acting and gentle on surfaces whilst being tough on grime, moss and mould.

At Chemwash Auckland, we always strive to do the best job possible and we ensure our equipment is of the highest
quality and certified to deliver the best results. Contact us today to learn more and request a quote.

What our clients are saying

Jan & Paul


"After months of struggling unsuccessfully to clean the moss, mould and dirt on the outside of our house with spray on applications and waterblasting, I called Chemwash. Within 24 hours the house went from looking as if it needed a good coat of paint to looking as if it had just had one. We were thrilled with the result. But the best thing was that Chemwash turned up when they said they would, did the job at the price they quoted. I would thoroughly recommend Chemwash to anyone."
