Roof Washing in Caloundra
Caloundra's established tile roofs grow lichen and black streaking quickly — the sea air keeps everything damp, and left alone it lifts tiles and blocks valleys. We clean tile, Colorbond and metal roofs safely, and treat the growth so it stays off for years.
Local & practical
Caloundra has a lot of established brick-and-tile homes close to Kings Beach and Bulcock Beach, and the constant sea air keeps tile roofs damp enough that moss and lichen take hold fast. Left unchecked it holds moisture against the surface, lifts tiles and eventually shows up as blocked valleys and gutter overflow in a storm.
Inland at Pelican Waters, Little Mountain and the Aura estate the roofs are newer — dark Colorbond that shows every bit of chalky oxidisation and dust. We match the method to the roof: a soft wash and chemical treatment for tile, and a controlled wash for Colorbond and metal that lifts oxidisation without harming the coating.

Cleaning a Caloundra roof — harnessed, with a ground exclusion zone.
How we do it
Our process
Inspection
Roof type, pitch, height and condition — we note anything brittle or already cracked so we can work around it.
Safety setup
Harness and anchor points, and a marked exclusion zone on the ground below.
Clear debris
Gutters and valleys cleared first so water and residue can drain away properly.
Treat & wash
Soft-wash chemical treatment, then a wash at the right pressure for your roof type.
After-treatment
A longer-acting biocide so moss and lichen take years, not months, to return.
Before / after — oxidised, streaked metal roof brought back.
Good to know
Will pressure cleaning break my tiles?
Not the way we do it. Tile roofs are soft washed and treated — we avoid the high pressure that strips the protective glaze. Any tiles that are already cracked or slipped are identified first and we work around them.
A standard clean doesn't include re-pointing or re-bedding ridge caps, but we'll photograph and flag anything that needs a roofer.
Pricing. Typically $400–$900 depending on roof size, pitch, height and how much growth there is. Free quote, and cheaper bundled with a house wash or gutter clean.
FAQ
Common questions
Does roof cleaning actually extend the life of my roof?
Yes. Removing moisture-holding growth reduces tile movement, rust and blocked valleys — all of which lead to leaks and early replacement.
How long until the moss comes back?
With our after-treatment, usually 2–4+ years. Caloundra's sea air means an untreated roof can be visibly green again within a year.
Can you clean my solar panels while you're up there?
Yes — it's the ideal time. See Solar Panel Cleaning.
Do you also do gutters while you're on the roof?
Yes, gutters and valleys are cleared as part of every roof wash — see Gutter Vacuuming for a dedicated clean.
