What's in the Treatment
Professional Quaternary Ammonium (Quat) Formula
No Chlorine Bleach
Controls Moss, Lichen, Algae & Mould
Low-Pressure Application
Helps Reduce the Need for Aggressive Waterblasting
Suitable for Residential & Commercial Properties
Professional Moss & Lichen Treatment
At The Moss Crew, we use a professional-grade treatment containing 50–51% Benzalkonium Chloride, a highly effective quaternary ammonium compound (Quat) trusted throughout the cleaning and property maintenance industry for controlling moss, lichen, algae, mould and other organic growth.
Our treatment does not contain chlorine bleach. Unlike chlorine-based products, Benzalkonium Chloride works by targeting organic growth at its source without the strong odours and harsh effects often associated with bleach-based treatments.
Applied at low pressure, our treatment penetrates moss and lichen and continues working over time, allowing natural weathering to remove dead growth while helping to protect the integrity of your roof.

What to Expect
Treatment Timeline
Your roof won't look different on day one — and that's completely normal. Here's exactly what happens after we spray.
Day Of Spraying
Looks The Same
The treatment is invisible and needs time to work. This is completely normal — don't worry.
A Few Weeks
Moss Begins Dying
The treatment has taken hold. You'll start to see the moss lose colour and begin to break down.
1 To 3 Months
Moss Breaks Down
Dead growth starts loosening and fragmenting. The roof surface is being freed up underneath.
3 To 6 Months
Rain Washes It Away
Each shower carries the dead material off the roof. You'll start to see noticeably cleaner sections.
6 To 9 Months
Roof Noticeably Cleaner
For most roofs, this is the point where it's clearly transformed. Moss, mould and lichen are gone.
9 To 12 Months
Heavier Growth Clears
Roofs with more severe build-up take a little longer. Fully clear by the 12-month mark in most cases.
Why doesn't it look different right away?
The treatment works by killing the roots of growth, not blasting it off. That means no risk of cracked tiles or stripped coatings — and the results last far longer. The rain does the rinsing. You just wait.
