Is Your Roof Telling You Something?
Black or green streaks running down your roof tiles
Thick moss or lichen patches spreading across the surface
Roof looks dark and aged despite the house being well-maintained
Gutters constantly clogging with moss and debris
Neighbours' roofs look cleaner and better maintained
Worried about tile damage or voiding your roof warranty
The truth is: moss and lichen don't just look bad — they hold moisture against your tiles, accelerating cracking and degradation. Left untreated, a simple clean today can prevent thousands in tile replacement costs down the track.
Professional Soft Wash Roof Cleaning
We use a low-pressure soft wash system with professional-grade biodegradable treatments. Every tile is thoroughly cleaned without any risk of cracking, dislodging, or stripping protective coatings.

Why Our Method Is Different
High-pressure washing damages your roof
Cracks tiles, strips protective granules, forces water under the membrane — and the moss comes back within months.
Soft wash kills the problem at the source
Our treatment penetrates and kills moss, lichen and algae at the root. Results last 2–3 years. Zero tile damage.
