Commercial Roof Washing & Treatment Services

Professional Roof Cleaning and Preservation Solutions

The NZ Facilities Difference

Your roof takes a beating from the sun, wind, rain, moss, bird droppings, and whatever else the seasons throw at it. Left unchecked, all that grime doesn't just ruin your kerb appeal; it degrades your roofing materials and shortens their lifespan. That’s where we come in. NZ Facilities delivers professional, compliant and low-impact commercial roof cleaning services across Auckland, Wellington and wider NZ.

Our Commercial Roof Cleaning Services

Commercial Roof Treatments

We apply commercial roof treatment solutions that break down grime gradually without damaging surfaces. These treatments work over time to clean roof materials deeply while preserving protective coatings.

Low Pressure Roof Cleaning

Our low-pressure roof cleaning method gently lifts grime and organic build-up while protecting paint, coatings and sealants. It’s ideal for membrane and tile surfaces where maintaining the structural integrity of the roof is just as important as how clean it looks.

Green Cleaning Solutions Available

Eco matters. We offer environmentally responsible commercial roof cleaning using biodegradable products that are tough on grime but easy on runoff systems and landscaping. 

Expertise in Removing Lichen, Grime, Mould, and Stains

Lichen and mould can do more than ruin the look of your roof; they trap moisture, speed up decay and block drainage. We remove these stubborn invaders along with built-up grime and stains using non-abrasive techniques.

Commercial and Industrial Roof Washing

We service everything from warehouses and factories to schools and retail blocks. Our commercial and industrial roof washing solutions are scaled for larger sites, with the tools and experience to clean safely and efficiently.

Multi-storey Roof Washing

Height is no obstacle. We’re certified to work safely on multi-level and high-access sites, with the right equipment, anchor systems and planning in place. Whether it’s an office block or an apartment complex, our multi-storey roof washing team delivers a thorough clean.

ServIcing Auckland & Wellington

We're proud to serve Auckland and Wellington with our local expertise and quick response times. Our proximity, and focus on these two specific locations means we’re always nearby when you need us, ready to tackle your commercial property maintenance and renovation projects.

The Benefits of Commercial Roof Cleaning

Regular roof cleaning removes damaging organic matter before it can take root and cause corrosion, cracks or leaks. It protects coatings and sealants, saving you from costly repairs or premature replacement.

Debris and moss on roofs often end up in gutters, where they cause blockages and overflows. Our cleaning services help prevent this by keeping both the roof surface and surrounding drainage systems clear, functional and able to handle heavy weather.

A dirty roof makes an otherwise tidy building look neglected. Professional roof washing improves curb appeal, enhances brand perception and helps maintain the value of your commercial property by presenting a well-kept, properly maintained exterior to clients, staff and visitors.

Commercial roof washing involves access risks and safety requirements that DIY or general maintenance staff aren’t trained for. We bring the right safety systems, height certifications and procedures to make sure the job gets done without putting people (or your business) at risk.
