Cleaning & Growth Profile
Mount Dandenong Roofing & Weather Profile
What We See in Mount Dandenong
Terracotta tiles are particularly susceptible to biological colonisation — the textured surface profile retains moisture and provides physical anchorage for spores. On a shaded section, a terracotta roof can go from clean to fully covered in four to five years.
Why It Happens
Water sitting in a blocked gutter warms to ambient temperature rather than staying cold. When warm, still water contacts a cold tile surface during a storm, it behaves differently to flowing water — the risk of backing up under the lap joint at the gutter-tile interface increases.
How We Fix It
On roofs with a significant biological load, we recommend a re-inspection at 12 months after the initial clean. The first clean removes the bulk of the growth but some deep-rooted lichen may require a second treatment once the inhibitor has had time to work on residual rhizoids.
