High-Pressure Roof Cleaning
Decades of grime, gone in a day.
Adelaide roofs collect lichen on the south faces, dust off the plains, and a slow film of grime that flattens the colour of the whole house. A controlled high-pressure clean strips it back to the original surface — the before/after line as the wash moves across a roof is the most satisfying thing we do.
Cleaning is also the first step of every restoration, and an honest diagnostic: once the grime is off, the roof's true condition shows. We clean with professional equipment at pressures matched to the surface — enough to strip growth, never enough to damage pointing or drive water under laps.

Straight answers
Will high pressure damage my roof?
Not at the right pressure for the surface — that's the difference between professional equipment with an operator who roofs for a living and a hired machine. Old, fragile pointing is worked around and flagged rather than blasted.
Can I just clean the roof instead of restoring it?
If the surface underneath is in good shape, absolutely — a clean alone transforms the look. If cleaning reveals failing coatings or porous tiles, you'll have photos and a straight recommendation, no pressure.
