Roofing subcontracts in South Australia: what to check before you sign
In South Australia, a roofing subcontract is read alongside the Building and Construction Industry Security of Payment Act 2009 (SA), which gives you the right to make a payment claim and requires a payment schedule within 15 business days if the builder disputes it. 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.

South Australia rules that override your contract
Statute: Building and Construction Industry Security of Payment Act 2009 (SA)
- If the builder disputes a payment claim, it has to answer with a payment schedule within 15 business days (or any shorter period in the contract).
- South Australia follows the NSW template closely with few state-specific traps; disputes usually turn on claim validity and the strength of the builder's payment schedule reasons, and the Small Business Commissioner SA publishes the list of nominating authorities.
- Adjudication: through a private authorised nominating authority, with determinations typically within 10 business days of acceptance.
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 other states
Roofing subcontracts in SA: common questions
How long does a builder in SA have to respond to a roofing payment claim?
If the builder disputes your payment claim, it has 15 business days to answer with a payment schedule giving its reasons. The payment term itself comes from your contract, so read it before you sign.
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 SA roofing payment disputes go?
Authorised Nominating Authorities (list via Small Business Commissioner SA). Timing: through a private authorised nominating authority, with determinations typically within 10 business days of acceptance.
