How Often Should You Clean Your Roof on the Gold Coast?
Your roof is one of the most important parts of your home — but it’s also one of the most overlooked. Living on the Gold Coast means constant exposure to salt air, humidity, mould, heavy rain and harsh UV, all of which cause your roof to age faster if it’s not properly maintained.
So how often should you clean it?
The short answer:
Most Gold Coast roofs should be cleaned every 12–24 months.
But the real answer depends on your roof type, location and the environment around your home.
1. Homes Near the Beach Need More Frequent Cleaning
If you live close to the coastline — Palm Beach, Miami, Burleigh, Mermaid Waters, Runaway Bay, etc. — your roof is exposed to salt spray, which:
corrodes Colorbond faster
creates a sticky layer that traps dirt
encourages algae growth
weakens coatings over time
For coastal homes, we recommend:
Every 12–18 months
2. Roofs Under Trees Need More Attention
If your home is shaded or surrounded by trees:
moisture sits longer
mould grows faster
leaves block gutters
lichen and moss form more easily
In these cases:
Every 12 months (or even every 9 months if heavily shaded)
3. Tile Roofs vs Colorbond — Which Needs More Cleaning?
Tile Roofs (Terracotta / Concrete)
Tiles are porous, meaning they absorb moisture and hold onto dirt.
These roofs often show black mould streaks and lichen faster.
Recommended: Every 12–18 months
Colorbond Roofs
Colorbond is smoother and less porous, so it stays cleaner longer.
However, coastal salt and UV still wear the coating over time.
Recommended: Every 18–24 months
4. If You See These Signs — Your Roof Needs Cleaning NOW
Black or green streaks
White or grey lichen patches
Rust developing on screws or flashing
Overflowing or blocked gutters
Roof looks dull, faded or patchy
Water stains on ceilings inside your home
These are early warning signs of mould, moisture retention or surface damage.
5. Soft Washing Is the Safest Way to Clean a Roof on the Gold Coast
While pressure washing is fine for driveways, it can:
crack tiles
strip Colorbond paint
force water under flashings
void roof warranties
That’s why the preferred method is soft washing, using:
low pressure
safe cleaning solution
gentle rinsing
long-lasting mould prevention
It cleans your roof without causing damage.
6. Keep Your Roof Clean — and Your Home Protected
Regular soft-wash roof cleaning helps:
prevent leaks
extend your roof’s lifespan
maintain your home’s value
keep your solar panels working efficiently
