Open Monday to SaturdayWhat the black streaks are
The dark streaks running down a roof are usually algae and mould, growing in the moisture that sits on the surface. You notice them most on concrete tile and lighter Colorbond roofs.
Brisbane's heat and humidity grow them fast. High pressure puts the tiles or the finish at risk, so we soft wash: the cleaning solution breaks the growth down and a gentle rinse carries it away.
We finish with a check of the roof and clear the gutters of debris.

Will it crack my tiles? No.
Brisbane's heat and humidity grow moss, lichen and algae on roofs fast. We soft wash it off instead of blasting the roof with high pressure.

| Can crack tiles and strip coatings | A gentle, low-pressure rinse |
| Rough on older tiles and terracotta | Breaks down moss, lichen, mould and black streaks |

Roof Mould & Black Streak Removal questions
Not answered here? Call 0480 808 362 and we'll talk it through.
What are the black streaks on my roof?
Usually algae and mould growing in the moisture on your roof. They show up most on concrete tile and Colorbond. A soft wash breaks them down instead of just moving them around.
Is pressure washing safe for my roof?
High-pressure washing can damage roofs, so we soft wash instead. We use lower pressure and specialised cleaning solutions to remove the growth without damaging tiles or coatings.
Can you clean Colorbond roofs?
Yes. We use methods and solutions suited to Colorbond and metal roofing, which clean the roof without damaging the factory finish.
How often should I have my roof cleaned?
Every 2 to 3 years is typical for Brisbane homes. Roofs under heavy tree cover, or with shaded, south-facing sections, may need it more often.
