A Roof Treatment Selected After Assessment

Sydney's climate is tough on roofs. Heat, humidity, and regular rainfall create perfect conditions for moss, lichen, and algae to thrive. Over time, your roof becomes an eyesore—and these organisms can actually damage your tiles if left unchecked.

One Wet & Forget treatment is applied where suitable. Results depend on roof conditions and weather.

The Sydney Roof Doctor has worked on roofs throughout Sydney. We inspect the roof first, protect the surrounding property and explain what result to expect from the Wet & Forget treatment.
