Roof plumbing is one of those trades people don’t think about until the roof leaks — but it’s skilled, licensed work that keeps water out of every building in the country. If you’re starting a roof plumbing apprenticeship, you’ll want to know what it pays and how that grows. Your wage isn’t a number your boss invents; it’s set by a national award and it climbs every year. Here’s the plain-English version.
Short version: Apprentice roof plumbers earn a percentage of the qualified tradesperson’s rate under the plumbing award. That percentage rises each apprenticeship year, adults get a higher floor, and overtime, allowances and early competency sign-off all lift it. Check your exact rate with Fair Work’s free PACT calculator.
How apprentice pay actually works
Roof plumbers install and repair roofs, gutters, downpipes, flashings and rainwater systems — flashing, cladding and stormwater are their world. You train through a nationally recognised apprenticeship, typically the Certificate III in Roof Plumbing or a roof plumbing stream within the Certificate III in Plumbing. As an apprentice you’re a paid employee learning on the job and at TAFE or another registered training organisation.
Your minimum pay comes from a modern award — for roof plumbers that’s generally the Plumbing and Fire Sprinklers Award, though some employers apply an enterprise agreement instead. The structure is the same either way: an apprentice is paid a percentage of the qualified tradesperson’s rate, and that percentage increases as you move through your apprenticeship.
Picture a sliding scale, not a flat wage. In your first year you’re on roughly half the qualified rate; by your final year you’re close to nine-tenths. Once you finish and hold the qualification, you step up to the full rate.
Your pay by apprenticeship year
A roof plumbing apprenticeship usually runs about four years, with your award percentage rising at each stage. Progression generally happens one of two ways:
- Time-served progression — you move up a level roughly every 12 months.
- Competency-based progression — you move up as you complete the required units and prove the skills, which can be quicker.
Broadly, first-year apprentices sit at the bottom of the scale, the middle years climb steadily, and final-year apprentices land close to the qualified rate. Your first-year step can also depend on whether you’ve completed Year 12 — finishing school often puts you on a slightly higher starting percentage under many awards.
The exact percentages differ between awards and can change in the annual wage review, so use the shape above as a guide and confirm your real figure with the calculator further down.
What changes your pay
The base percentage is only the starting point. Several things move what actually lands in your account.
Adult apprentice rates
If you begin your apprenticeship as an adult — generally 21 or older when you start — you’re usually entitled to a higher minimum than a school-leaver. Awards set an adult apprentice floor so mature-age workers aren’t paid a junior wage. If that’s you, make sure your employer applies the adult rate.
Overtime and penalty rates
Roofing work follows the build, the weather and tight programs, so overtime and early starts are common. Overtime, weekend work and shift loadings are paid on top of your base rate under the award. For apprentices, those penalties can noticeably change a fortnight’s pay.
Allowances
The plumbing award includes allowances that can apply to your role, such as tool allowances, industry or site allowances, and payments for particular or difficult conditions. Roof work at height and in the elements may attract specific allowances too. Check what should be added to your pay — allowances are easy to miss and add up over a year.
Competency-based progression
If your training uses competency-based progression, finishing your units and being signed off early can lift you up the pay scale sooner. Make sure your employer and training provider record your progress promptly — being signed off on time is money in your pocket.
How to check YOUR exact rate
Here’s the reliable way to find your real number rather than guessing:
- Go to Fair Work’s Pay and Conditions Tool (PACT) at calculate.fairwork.gov.au.
- Open the pay calculator and search for the award covering your job — for most roof plumbers that’s the Plumbing and Fire Sprinklers Award.
- Enter that you’re an apprentice, your apprenticeship year, your age, and whether you’ve completed Year 12.
- The tool returns your current minimum base rate, plus casual, overtime and allowance figures where they apply.
If you’re unsure which award or enterprise agreement covers you, check your contract, ask your employer, or contact the Fair Work Ombudsman through fairwork.gov.au. An enterprise agreement can pay above the award but never below it.
After you qualify
When you finish the apprenticeship and hold the qualification, you move to the full qualified tradesperson rate — a clear step up from your final apprentice year. Roof plumbing is a licensed trade in most states and territories, so you’ll usually need to hold the appropriate plumbing or roof plumbing licence to work unsupervised and, eventually, to run your own jobs. Check the requirements with your state authority.
From there, roof plumbers have strong earning potential. Commercial roofing and cladding, metal roofing on large projects, and running your own business all pay above the base rate. Getting qualified and licensed is the gate — after that, where you work and whether you go out on your own drive your income.
FAQ
How much does a first-year roof plumbing apprentice earn?
A first-year apprentice earns the lowest step on the percentage scale — broadly around half the qualified tradesperson rate — with the exact figure depending on your award, age and whether you’ve finished Year 12. Use the PACT calculator for your current number.
Do adult apprentices get paid more?
Usually, yes. Most awards set a higher minimum for apprentices who start at 21 or older, so mature-age apprentices aren’t paid a junior rate. Confirm your entitlement through PACT.
Is roof plumbing a licensed trade?
In most states and territories, yes — plumbing work, including roof plumbing, is licensed and regulated. You train as an apprentice, then hold the appropriate licence to work unsupervised. Check the exact rules with your state authority.
Can I earn more before I finish?
Yes. Overtime, weekend and shift penalties, and allowances all add to your base rate. If your apprenticeship uses competency-based progression, completing units and getting signed off early can move you up a level sooner.
Does the apprenticeship cost me anything?
You’re paid to work and train. Some course and tool costs can apply, but there are government incentives and support payments for apprentices — see the payments and schemes guide, and check apprenticeships.gov.au.
