Williamstown's roofs and history
Early timber, later Victorian
The Hobsons Bay Heritage Study 2006 found predominantly Victorian areas within Williamstown, with many early timber dwellings and later Victorian houses. Two cottages in Cox's Garden are thought to date from 1851 to 1853.
Heritage precincts
The study covers over 300 individual places and over 20 precincts across Hobsons Bay. Council's precinct guidelines name Nelson Place, Cox's Garden, Ferguson Street, and Hannan's Farm and Williamstown Beach among them.
Gutters with a profile
Victorian houses typically had ogee or half-round gutters with round downpipes. Swapping them for a modern square profile changes how the house looks from the street.
On the water
eMelbourne describes a peninsula at the mouth of the Yarra. Victorian Places notes the town faces the calmer waters of Hobsons Bay, while a reserve at Gellibrand Point faces southerly winds.
Homes today
At the 2021 Census, 56.2% of occupied dwellings were separate houses and 30.2% semi-detached, row, terrace or townhouses.
Slate, iron and the permit question
Hobsons Bay's guidelines tell owners to contact council to find out whether a house is in a Heritage Overlay and whether a permit is required. For additions, they say matching the roof pitch and the cladding material is essential. The same thinking applies to a repair.
Slate is worth keeping while it's sound. A roofer who knows slate can replace broken pieces and refix slipped ones, and a full slate re-roof costs far more than that. Read slate and heritage roofs and our page on slate.
Galvanised iron on a timber cottage is usually replaced in the same corrugated profile. Close to the water, ask which product the roofer will use. BlueScope's own examples class Williamstown as calm marine water, where it recommends ZINCALUME more than 100 m from the high water mark and standard COLORBOND at any distance. The open bay from Altona to Portsea is classed as exposed, with stricter distances, so if your house looks straight onto the bay near Williamstown Beach or Gellibrand Point, have the roofer confirm which category applies.
What to ask a roofer working on a period house
- Have you worked on slate or period iron roofs, and can I see photos?
- Will you match the existing pitch, profile and gutter shape?
- Which metal product will you use, given how close I am to the bay?
- Have we checked whether a planning permit is needed?
If it were our roof
On a Williamstown period house, we'd repair slate rather than replace it, match iron with iron, and keep the ogee or half-round gutters. One phone call to council about the overlay before work starts saves a lot of grief. Send us the job and your postcode: where we have a licence-checked roofer for Williamstown, they'll be the only roofer to receive your contact details, and where we don't, we'll tell you straight away.
