What's really growing on Keon Park roofs
Keon Park's post-war brick veneer homes carry concrete and terracotta tile roofs that have now had decades to lose their factory glaze, which leaves the tile surface open to moss and lichen once dirt and organic matter settle in. The suburb's tree cover isn't heavy, but established nature-strip trees and back garden growth are enough to keep some roof pitches shaded through the day, especially on the older, unrenovated streets. A soft wash treats that growth properly: a biocide kills moss and lichen at the root, then low-pressure washing lifts it away without cracking the ageing tile the way a high-pressure blast can.
Keon Park's moderate street tree cover means moss growth tends to concentrate on the shadier side of the roof rather than across the whole surface, so we focus the treatment where it's actually needed.

The process
How a True Roof soft wash works
2
Treat
A biocide treatment is applied so moss and lichen are killed at the root, not just wiped off the top.
3
Soft wash
Low-pressure washing lifts the dead growth and grime without driving water under the tiles or stripping the surface.
4
Clear & check
We flush the wash debris out of the gutters and do a final check so you are left with a clean roof and clear downpipes.
Roof types in Keon Park
Soft washing suits terracotta and concrete tile roofs and older, more fragile tiles that high pressure would damage. Colorbond and metal roofs are washed even more gently. If a roof is due for more than a clean, we will flag whether sealing or restoration is the better spend.
Our standard
Our cleaning crews are fully insured, and any repair work we recommend is backed by a 7-Year Workmanship Guarantee and a 10-Year Dulux Acratex Material Warranty.

Roof clean What affects your price
What drives the cost of cleaning in Keon Park
- The extent of moss and lichen build-up across the roof.
- Roof size and pitch on standard brick veneer blocks.
- How much gutter and valley debris needs clearing alongside the wash.
The hidden cost of moss

Moss is not cosmetic. It is structural damage in slow motion.
Lichen and moss anchor into tile surfaces and hold moisture against them 24 hours a day. That constant dampness accelerates freeze-thaw micro-cracking through Melbourne winters, erodes pointing mortar, and quietly voids the tile manufacturer's warranty. Most homeowners find out the hard way when tiles start fracturing or when their insurer queries maintenance records after a claim. A soft wash costs a fraction of one tile replacement row and it buys back years of tile life.

What Melbourne homeowners say
Keon Park roof cleaning — your questions
Yes. Soft washing uses a biocide to do the cleaning chemically and only low pressure to rinse, which avoids the tile cracking and surface stripping that high-pressure cleaning risks on ageing post-war tile.
Most homes here do well with a clean every two to three years, matching the suburb's moderate tree cover, though roofs under more established garden trees may need it sooner.
Yes. We photograph any cracked tiles or lifted ridge caps found during the wash and give you an honest separate quote — cleaning alone doesn't fix structural issues.
