How much does slate roofing cost in Melbourne?
We do not answer that with a price, because no government source sets one. Over A$10,000 the work needs a major domestic building contract with a registered builder, and the checker lists each rule with its source. Check which rules apply at your job's value.
Do I need a registered builder to re-slate a roof?
Once the cost of the work is more than A$10,000, a major domestic building contract is required and the builder must be registered under the Building Act 1993. The Commission's class list has no class named for roof slating, so ask which registration the quote is under.

Process
How does a council describe slate repair?
A Victorian council's heritage sheet says: Before complete replacement is considered, the condition of the existing slate should be clarified. Salvaged slate should be reinstated in addition to replacement slates where necessary. It says that the new slate should match existing in profile, colour, texture and finish
What do councils say about flashings?
The battening and nailing system as well as the proposed materials for flashings and valleys should be documented as part of the application. Traditionally, lead flashings were used. The use of lead flashing today can pose occupational, health and safety concerns, particularly where rainwater is collected for drinking purposes. In most situations, galvanised steel flashings may be an acceptable alternative.
Timing
How quickly can someone get to me?
We cannot promise a time. It depends on the provider's bookings. Form and phone enquiries are passed to a local provider, who contacts you directly.
Can a slate roof be worked on in any weather?
No source read for this site says. The provider decides on the day, so ask how the quote treats wet days.
Permits and approvals
Does replacing slates need a planning permit?
It depends on the property. Under the Heritage Overlay you do not need a permit for routine repairs and maintenance that replace ‘like for like’ so long as they do not change the appearance of the place or impact on its significance. A council sheet says that generally, where existing original or significant roof cladding requires complete replacement, a permit is required. If you have any questions, or are unsure, please contact Council’s planning department.

Service area
Which suburbs do you cover?
Melbourne. Five pages are written around one City of Yarra precinct statement each: Fitzroy, Collingwood, Richmond, Abbotsford and Cremorne. The rest are covered on the same terms.
Do you do the work yourselves?
No. This site is run by a marketing company, which passes each enquiry to an independent licensed local provider. The provider inspects the roof, quotes and does any work itself; we hold no licence or registration and do none of it.
