What's really growing on Keilor roofs

Keilor's established homes, many dating from the 1960s through the 80s, carry decades of moss and lichen build-up on their concrete and terracotta tile roofs, particularly on properties shaded along the Maribyrnong River escarpment. That moderate tree cover keeps roof surfaces damp for longer after rain than the more open blocks further from the river, giving moss plenty of opportunity to establish. We clean with low-pressure methods only, since high-pressure washing can crack or strip the surface off tile roofs this age, so the roof comes up looking sharp without shortening its remaining life. Most Keilor roofs do well with a clean every two to three years, a little more often on the shadier river-facing blocks.

Keilor's moderate tree cover along the Maribyrnong River escarpment keeps some roofs damp for longer after rain than the more open blocks elsewhere in the suburb, which speeds up moss growth on those shaded sections.

The process

How a True Roof soft wash works

1

Inspection

We check tile condition, valleys and pointing first, and photograph anything cracked or corroded before we touch it.

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 Keilor

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.

What affects your price

What drives the cost of cleaning in Keilor

  • The roof's size, pitch and how much shade it gets from riverside trees.
  • How much moss and lichen has built up since the last clean.
  • Whether the roof is concrete tile, terracotta or colorbond metal.
The hidden cost of moss

Clean it now. Replace it never.

Soft wash clean

from $750

Tile replacement + re-roof

$8,000 – $20,000+

Removes moss, lichen, and algae at the root
Preserves manufacturer tile warranty
Safe, no high-pressure tile fracturing
Completed without disrupting the household
Restores tile porosity and water run-off
Prevents pointing deterioration beneath the 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

"From the initial consultation to the final day of work, True Roof was exceptional. Their attention to detail on the roof painting and repairs was impressive. Our home's aesthetic appeal has increased ten-fold!"

Liam O'Connell

Williamstown
"True Roof fixed a leak that three other companies couldn't find. Incredibly thorough inspection, identified the real cause and repaired it properly. No more ceiling stains. Five stars, easy."

David P.

Essendon
"After heavy rain last winter our bedroom ceiling started showing water marks. True Roof diagnosed and sealed a cracked ridge tile within 24 hours of calling. Absolutely saved us from a much bigger repair bill."

Tanya Briggs

Sunshine
"Our terracotta roof was covered in moss and looked awful. The roof cleaning and sealing service made a massive difference. They were thorough and the roof looks incredible. Great value for money."

Sophia Chen

Box Hill
"Our tile roof was green with lichen after years of neglect. The soft wash brought it back to life without damaging the tiles. I wish we'd done it sooner. Very professional team."

Sandra Liu

Glen Waverley
"Our terracotta tiles were green with moss. After the soft-wash and restoration treatment they look incredible, and the Dulux coating means they're protected for years. Highly recommend."

Keilor roof cleaning — your questions

Most homes do well with a clean every two to three years. Properties shaded along the Maribyrnong River escarpment tend to hold moisture longer and may need it a little more often to stay ahead of moss.
It can. High-pressure washing cracks older concrete and terracotta tile and strips the protective surface, which is a real risk on Keilor's 1960s to 80s homes, so we use low-pressure methods instead on every job.
Yes, the moderate tree cover near the escarpment keeps some roofs shaded and damp for longer after rain than blocks further from the river, which speeds up moss and lichen establishment on those roofs.
