What's really growing on Reservoir roofs
A roof clean is the quickest way to lift the look of a Reservoir home, and on the suburb's post-war brick and weatherboard houses it matters for more than looks. The original concrete and terracotta tiles hold moss and lichen on the shaded, south-facing sections, and that growth keeps moisture sitting against the surface long after the rain stops. We use a soft-wash method — a biocide treatment that kills the growth at the root, then low-pressure washing — so the tiles are cleaned without the surface being blasted off, which is a real risk on older Reservoir roofs. We photograph any cracked tiles or failed pointing we find along the way, so nothing gets missed.
With rain on around 120 days a year, Reservoir roofs rarely get the chance to fully dry out on the shaded side, which is exactly where moss and lichen take hold first.

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 Reservoir
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 Reservoir
- Roof size and pitch, and how much moss and lichen has built up.
- Whether the tiles are sound enough for a straight clean or need repairs flagged first.
- Clearing the wash debris out of the gutters, included as standard.
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
Reservoir roof cleaning — your questions
It can. High pressure strips the surface off older concrete and terracotta tiles and can force water underneath. We soft-wash instead, which cleans thoroughly at low pressure and protects the tile surface, so the result lasts longer.
Because the biocide kills the growth at the root rather than just rinsing it off, regrowth is much slower. How long depends on shade and nearby trees, but a treated Reservoir roof stays clean far longer than a pressure-only wash.
If the tiles are sound and just dirty, a clean is enough. If the surface has gone porous or the colour has faded off, a restoration protects the roof far better. We look at the tiles and tell you which yours needs.
