Commercial Roof Cleaning – Auckland and Wellington

Say Goodbye To Moss, Algae and Unsightly Stains

Accessible.
Efficient.
Safe.

The roof is the least accessible and least inspected area of a building, and cleaning it presents many challenges – gaining access, having the right equipment and doing the job safely. It’s little wonder so many are left unwashed and deteriorating.

Luckily you can bring in our expert roof cleaning Auckland team in Auckland or Wellington, and have this all taken care of, simply, efficiently and most of all safely. Trust us to thoroughly clean every inch of your roof, removing all dirt, grime, salt, mould, lichen and moss. And, at no extra cost, all our roof washing options include the cleaning of the building’s gutters and downpipes.

We’ve got you covered.

Our Roof Cleaning Services

Two Different Approaches To Ensure The Perfect Solution


Water Blasting —

A complete clean with lichen removal. Instantly bring your roof back to life.


Spray and Leave Application —

A slow acting BWS bio-cleaner that sets deep into contaminants for an effective result, and works over time.


On completion of both of these options, your roof can be treated with an algae spray to protect against re-growth. And because it can be hard to see your roof, we’ll also provide before and after photos, plus images of areas that may require remedial attention.
