Roof cleaning is the process of cleaning any foreign dirt and matter, including mould and moss, from the roof of a property.

When roof cleaning in Auckland is done periodically, together with a mould treatment application, it helps prolong its lifespan. It also prevents early damage, keeping the property at its best and saving costly repairs in the future.

Yes! Our roof cleaning services in Auckland use environmentally conscious roof cleaning products like our roof cleaning and treatment.

This natural roof cleaning formula cuts through stubborn grime, dirt and grease just as well, if not better, than chemical cleaners. It also gives a layer of protection against moss, mould and lichen.

Our roof cleaning product is carefully formulated to quickly penetrate, emulsify and remove light to medium dirt debris. Being made from natural plants and minerals, the roof cleaning product leaves behind no chemical fumes or residue! It’s our proudly 100% natural roof cleaning solution!

We are very conscious of water wastage in Auckland, particularly during drier seasons where water restrictions are in place.

Wherever possible, we use clean recycled water from hospitality premises like motels, hotels and environmentally-conscious hotels. We reuse the final rinse water that was used in cleaning linen in commercial buildings with eco-friendly products in a partnership that allows both of our industries to be less wasteful.

The water from this final rinse process is diverted and stored, we pick it up in our purpose-made 2000lt wash service trailer, and it’s used in our roof cleaning service.

Nope! Our roof cleaning products are gentle enough not to harm any outdoor furniture if any water or product sprays should land on them. The soil and plants can even benefit from the extra nutrients in our eco-friendly house washing products!

Eventually, yes, but we make sure it is safe to do so! Before we begin cleaning an Auckland roof, we inspect it to see what needs to be cleaned first. We remove all larger organic debris and take it off-site prior to the final wash. If there is light to medium organic dirt and debris on the roof, it is safe to be washed straight into the storm system. If the waste is particularly heavy, contains paint flakes and other non-eco-friendly matter, we will block the storm drains off first before beginning so that we can filter the non-eco matter out of the dirty water before allowing it to run into the stormwater system.

No, if you read the terms and conditions of your paint warranties – particularly from companies like Resene, Wattyl and Dulux, you will find that they require a recorded annual cleaning to maintain the valid manufacturer’s warranty.

We provide these services to adhere to those warranties! All the market-leading paint manufacturers approve our Auckland roof cleaning process and products to keep your warranty valid.

We provide these services to adhere to those warranties! Our Auckland house washing process and products are approved by all the markets leading paint manufacturers to keep your warranty valid.

Our experts come from a lot of experience dealing with weather tightness in Auckland properties’ roofs. Weather tightness just means that all points of your roof are safe from the external elements, and the inside of your property is dry – and stays dry. Before we begin an Auckland roof cleaning service, we need to check that us spraying water and products onto your roof will not seep through any cracks in the weather tightness.

If there is weakness in your roof or other points of construction, then your property is at risk of weather damage and water damage from being cleaned.
