Roofing subcontracts in Victoria: what to check before you sign
In Victoria, a roofing subcontract is read alongside the Building and Construction Industry Security of Payment Act 2002 (VIC), which caps subcontract payment terms at 20 business days. The contract itself still decides the risks that cost roofing and roof plumbing subcontractors most: weather delay and notice; water damage to other trades; safety and access provided by others.

Victoria rules that override your contract
Statute: Building and Construction Industry Security of Payment Act 2002 (VIC)
- Payment terms for subcontractors are capped at 20 business days after the payment claim. A longer term in the contract doesn't change that.
- If the builder disputes a payment claim, it has to answer with a payment schedule within 10 business days (or any shorter period in the contract).
- The Act was substantially reformed with effect from 15 April 2026: the old excluded-amounts and claimable-variations regimes are abolished, so damages, time-related costs and disputed variations can now generally be included in a payment claim, and reference dates are abolished too.
- Adjudication: through a private authorised nominating authority; the reforms are recent and practice under them is still settling.
Where roofing and roof plumbing subcontractors lose money
Weather delay and notice
Wind and rain stop roofing work outright. Check whether weather gives an extension of time and how it must be notified; a daily notice with an absolute bar is easy to miss.
Water damage to other trades
If water gets in before the roof is complete or after other trades penetrate it, broad indemnities can make you liable for damage throughout the building. Limit liability to damage caused by your own work.
Safety and access provided by others
Edge protection, scaffold and hoisting are often the builder's responsibility. Delays in providing them should be delay events.
Penetrations by other trades
Services trades cut through finished roofs. Re-flashing and sealing their penetrations should be a variation.
Three things to push for in your departures schedule
- Extension of time for weather with simple notice
- Liability for water damage limited to damage caused by your own work
- Re-flashing of other trades' penetrations paid as a variation
The free scanner finds these clauses in your actual contract in about two minutes and writes the departures schedule for you.
What the Index says
Live figures from the Australian Subcontract Index, 90 real subcontracts. The Index holds only 1 roofing contract so far, under the 10-contract threshold, so these are national figures across all trades. Nothing under 10 contracts is ever shown.

Roofing subcontracts in VIC: common questions
How long does a builder in VIC have to pay a roofing subcontractor?
No more than 20 business days after your payment claim, whatever the contract says. If the builder disputes the claim, it has 10 business days to answer with a payment schedule giving its reasons.
Is a roofer liable for water damage caused after other trades cut the roof?
It depends on the indemnity and defects clauses. A well-drafted subcontract limits your liability to damage caused by your own work and makes sealing other trades' penetrations a variation.
Where do VIC roofing payment disputes go?
Authorised Nominating Authorities (list via the Building and Plumbing Commission, formerly the VBA). Timing: through a private authorised nominating authority; the reforms are recent and practice under them is still settling.
