Roof Cleaning in Leichhardt

Across most of the older estates, unglazed terracotta is the main roof. The heritage studies record it as the main cladding in the Whaleyborough and Wetherill estates around Norton Street, on the single-storey houses of Leichhardt Street and Stanley Street, and along North Avenue, South Avenue and The Avenue in the Scarvell Estate. Without a glaze the tile is porous and stays damp for longer after rain, which gives lichen and moss something to grip.

These roofs were also built to be looked at. Terracotta ridging and finials, chimneys, and in the Scarvell Estate a skyline of elaborate chimneys and decorative ridges all face the street. Those pieces can crack under careless footing or a hard jet of water, so they shape how each roof is approached.

Iron is the other main material. It predominates across the Excelsior Subdivision, and where the Scarvell cottages have iron it is mostly on the verandahs. On metal the concern is the coating, along with the dark mould and streaking that settle on it, and roofs beside Parramatta Road and the City West Link can also collect grime from traffic.

Access needs thought as well. Houses in the older subdivisions are tightly spaced, and in the Leichhardt Street and Stanley Street area neighbouring hipped roofs sit near enough to leave V-shaped gaps between them, so we work out how to reach every plane before cleaning starts.

In Leichhardt's conservation areas the roof is part of the streetscape, described by council right down to the ridging and finials. A clean brings back the warm colour of unglazed terracotta and the even look of a well-kept iron roof, and on a row of similar cottages the difference shows clearly from the footpath.

The bigger return is time. Moss and lichen left on porous terracotta hold moisture against the tile year after year, and growth that has rooted into the surface only gets harder to shift the longer it stays. Once it has been removed we apply an anti-mould and lichen treatment to slow its return.

Original roofing is worth keeping for practical reasons too. A cracked original tile or a finial knocked off a ridge is far harder to match than to avoid breaking in the first place, which is why the cleaning method is chosen surface by surface, from a soft wash to controlled pressure.

Every roof clean also comes with before-and-after photos. Whether you are planning repairs, comparing a roofer's advice or getting the house ready to sell, that gives you a dated record of the roof and of the work done on it.
