Roof damage rarely arrives loudly. It creeps in — a black streak here, a green patch there — until it's too late and you're paying for a replacement that proper roof cleaning Sunshine Coast specialists could have prevented years earlier.
1. Black streaking down tiles
Those long dark stains aren't dirt. They're algae and mould feeding on the surface. Untreated, they hold moisture against tiles and accelerate breakdown.
2. Visible lichen patches
Crusty white, grey or orange spots are lichen — a fungus that physically anchors into the tile. Pressure-washing it off without treatment leaves the root, and it grows back within months.
3. Moss in tile valleys
Moss traps water exactly where you don't want it. On terracotta and concrete tile, this is how you get cracking, lifting and eventual leaks.
4. Faded or chalky Colorbond
Salt and pollution sit on the coating and break it down. Soft-wash treatment removes the contamination and extends the painted finish.
5. Discolouration around solar panels
Bird droppings and shading cause hot-spotting and uneven weathering. Treat the roof and panels at the same time to stop both problems.
If you're seeing any of these on your Sunshine Coast home, a soft-wash roof treatment will reverse most of it — without the damage that high-pressure cleaning causes.
