Why Early Roof Treatment Matters – Part 1 - Earlwood Case Study

This Earlwood property featured a tiled roof with significant lichen contamination, particularly on the west-facing solar panels at the rear of the home. The north-facing panels were affected but to a lesser degree.

The panels, approximately 10 years old, underwent careful lichen removal followed by a professional pure-water clean. Shortly after the service, the customer reported midday peak power output levels not seen since 2021 — a strong indicator of restored system performance.

With improved government battery rebates now available, the homeowner is preparing to install battery storage to maximise solar gains.

Several weeks later, we returned to apply a biocide roof treatment to address widespread lichen across the tiled roof. We will continue to monitor the roof and panels over time, as the treatment works gradually to kill lichen and algae at the root system level.

This project highlights why early intervention is important. Once lichen becomes heavily established, it can strongly bond to both roof surfaces and solar panel glass, increasing cleaning difficulty and in some cases leaving permanent marks or etching behind.

Regular maintenance and preventative roof treatment can help protect both roof appearance and long-term solar performance.
