What's really growing on Highett roofs

Highett's post-war brick veneer homes carry concrete and terracotta tile roofs that are now old enough for the original factory glaze to have worn thin, leaving the surface open to moss and lichen once grime builds up. Being close to the bay, roofs here also pick up salt-laden air and windblown grit that adds to that grime layer over time. A soft wash treats the growth at the root: a biocide kills moss and lichen, then low-pressure washing lifts it away without cracking older tile the way a high-pressure blast can. We clear gutters and valleys of debris as part of the same visit and photograph any tile or pointing issues we find.

Highett's proximity to the bay means roofs collect salt-laden air alongside the usual grime, and combined with moderate garden tree cover, that's enough for real moss growth on shaded tile.

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 Highett

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 Highett

  • The extent of moss, lichen and salt grime build-up on the tile.
  • Roof size and pitch on standard brick veneer blocks.
  • How much gutter debris needs clearing alongside the wash.
The hidden cost of moss

Clean it now. Replace it never.

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

"Had an urgent repair needed after storm damage. True Roof responded quickly, gave a fair quote, and fixed the leak efficiently. Very happy with the quality of work and the professionalism of the team."

Marcus Bellwether

Bentleigh
"Two years of chasing a leak that stained our ceiling. True Roof found the source on the first visit: a cracked valley that everyone else missed. Fixed same day. Exceptional."

James McKinley

Toorak
"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."

Anna W.

Dandenong
"True Roof transformed our tired, leaky tile roof into something that looks brand new. The entire restoration process was smooth, the team was professional, and the communication was excellent. Highly recommend their services in Melbourne!"

Highett roof cleaning — your questions

Yes. Salt-laden air adds to the grime layer on top of moss and lichen, so roofs here often need a proper soft wash rather than just a light rinse to fully lift the build-up.
Yes — that's why we use it. It cleans chemically at low pressure, avoiding the cracking and surface damage that high-pressure washing risks on Highett's ageing post-war tile roofs.
Most homes here do well with a clean every two to three years, though shadier roofs under established garden trees may need it closer to every two years to stay ahead of regrowth.
