Roof cleaning in the City of Logan
Updated October 2026
If your roof has gone dark, patchy or green, it is not just dirt. Moss, lichen and algae hold moisture against the tiles, break down coatings and slowly shorten the life of the roof. A proper roof clean restores the look of the house in a day and, more importantly, stops that growth doing structural damage.

What professional roof cleaning involves
- A walk-over inspection first, because pressure cleaning a roof with cracked tiles or failed pointing pushes water straight into the ceiling
- High-pressure cleaning with roof-specific equipment, worked from the ridge down so water sheds the way the roof is designed to
- Treatment for moss and lichen so the growth dies at the root rather than returning in a season
- Gutters and downpipes cleared of the sludge the clean washes down
Asbestos cement roofs are never pressure cleaned. If a roof might be asbestos cement, the roofer will stop and recommend testing, and any work on it goes to a licensed asbestos removalist.
Metal roofs are cleaned at lower pressure with the right chemicals, because high pressure can damage older coatings on Colorbond and galvanised steel.
Why Logan roofs grow lichen and moss
The subtropical mix of humidity, warmth and a long wet season is exactly what lichen wants, and the southern pitch of almost every roof in the region gets less sun, which is why growth nearly always shows up there first. Shaded, tree-lined streets through Daisy Hill, Shailer Park and Springwood stay damp longer after rain. Acreage blocks at Jimboomba, Logan Village and Greenbank collect leaf litter all year. And across the older core at Woodridge and Kingston, a concrete tile that lost its original surface decades ago is a sponge for growth.
Beenleigh, Eagleby and the river flats
Roofs through Beenleigh, Eagleby, Waterford and Edens Landing sit in the low country along the Logan and Albert rivers, where humidity hangs about and gutters fill with whatever the last big rain brought down. Clearing the gutters as part of the clean matters more here than almost anywhere, because an overflowing gutter on a low-lying block puts water exactly where you do not want it.
What roof cleaning costs
Guide pricing only. A pressure-clean-only visit on an average single-storey home typically runs $400 to $900, with larger, steeper or two-storey roofs sitting higher, often up to around $1,500. Moss treatment, gutter clearing and minor repairs add to that. If you are cleaning the roof as step one of repainting or restoring it, get the whole package quoted at once, because it is cheaper than booking each trade separately. The numbers are in our roof restoration cost guide.
A warning about cleaning old roofs
Cleaning strips everything off the tile, including whatever remained of the original coating. A badly weathered roof can look blotchy after a clean, which is why roofers often recommend cleaning as preparation for roof painting rather than as a stand-alone cosmetic fix on an old roof. A good local roofer will tell you honestly which situation yours is before you spend the money.
Safety and licensing
A wet tile roof is one of the most dangerous places a person can stand. The roofers we work with use harnesses and edge protection and carry insurance for working at heights, which is exactly why this is not a job for a homeowner with a ladder and a pressure washer. In Queensland, building work valued over $3,300 generally requires a QBCC licensed contractor. A clean on its own can sit under that line, but once it is bundled with repairs or coating the whole job generally needs a licensed contractor, and the roofers we work with are licensed where the work requires it.

Frequently asked questions
How often should a Logan roof be cleaned?
Most local roofs benefit from a clean every 3 to 5 years. Homes under heavy tree cover or on shaded blocks may need it more often, because shade speeds up regrowth.
Will pressure cleaning damage my tiles?
Not when it is done with the right equipment and technique on a sound roof. The risk comes from cleaning over cracked tiles or failed pointing, which is why a proper inspection comes first.
Does roof cleaning get rid of lichen permanently?
Cleaning removes it, and a biocide treatment slows it coming back, but nothing stops regrowth forever on a bare, porous tile. Sealing or coating the roof after cleaning is what keeps lichen away long term.
Can I clean the roof myself?
We would not recommend it. Wet tiles are treacherous, domestic pressure washers drive water under tiles, and a fall from a single-storey roof is life-changing. The quote for a professional clean is small against that risk.
Is it worth cleaning the gutters at the same time?
Almost always. The clean washes sludge straight into them, and a blocked gutter is one of the most common causes of water getting into eaves and walls. Most quotes include clearing them.
