Roof Cleaning Allambie Heights Exterior Cleaning

Allambie Heights sits high on the ridges behind Manly, an elevated, bush-backed suburb where roofs take a beating from moss and lichen. Surrounded by reserve and heavy canopy, tile and Colorbond roofs here stay damp and shaded, and organic growth streaks them black and green — often the first thing you notice from the street or the valley below.

Why roofs here need attention

Lichen roots into porous concrete tiles and holds moisture against the surface, accelerating wear and staining. On the elevated blocks of Allambie Heights, a growth-covered roof is visible from a long way off and drags down the whole property’s appearance.

How we clean roofs

Soft washing, never high pressure — high pressure fractures the tile surface and voids many roof warranties. We treat the growth at the root with the correct chemistry so it’s killed off rather than blasted from the top, which slows regrowth well beyond a simple clean.
