Roofing Contract Template: What to Include and How to Sign It Online

A good roofing contract template does four jobs: it fixes the scope and price, sets a payment schedule tied to progress, deals with hidden damage before anyone finds it, and records a signature from the owner before the first tile or sheet comes off. This guide sets out the clauses, in order, with the rules that sit behind them. It is written for Australian roofing businesses and cites state regulators, so check your own state’s rules before you copy anything. US readers: this page covers Australian state rules, so look up your own state’s licensing board and consumer law before using any clause.

TL;DR

• Every residential roofing job needs a written contract. Regulators in NSW and Victoria are explicit on this.
• Tie payments to milestones (start, strip-off, completion), not calendar dates, and keep the deposit modest and within your state’s limit.
• Price hidden damage (rotted battens, decking, sarking) in the contract as a per-sheet or per-metre rate, and require written approval before extra work starts.
• Separate your workmanship warranty from the manufacturer’s product warranty.
• Collect the form details, generate the contract, get the signature and take the deposit in one flow, rather than juggling PDFs, emails and payment links.

Why a roofing contract needs more than a quote

A quote tells the customer what you will charge. A contract tells both sides what happens when the job does not go to plan. Roofing is a trade where the plan often changes: you lift the old tiles and find the timber underneath is rotten, a storm arrives mid-strip, or the owner decides they want gutters done at the same time.

Without a signed document that anticipates those moments, you end up arguing over text messages. The NSW Government’s guidance for consumers states that all building contracts must be in writing, and describes the two main types: fixed price (or lump sum) and cost-plus. Other states have their own thresholds and forms, so the safest habit is to use a written contract on every residential job, whatever its value.

The legal downside of skipping this is real. Under NSW’s Home Building Act 1989, a contractor who starts work without a compliant written contract can be left unable to enforce payment. Schedule 2 of the Act lists terms that must be included in certain contracts, starting with the plans and specifications for the work, including any variations to them.

Check your state’s rules first

There is no single national roofing contract. Residential building work is regulated state by state, and thresholds, mandatory notices and deposit limits differ. Three examples from the regulators:

Thresholds change, so confirm the current figure with your state regulator (NSW Fair Trading, QBCC, Consumer Affairs Victoria or your equivalent) before you fix it into a template. Where a state mandates a particular form or consumer guide, that form comes first, and your own template should sit alongside it rather than replace it.

Many experienced builders also lean on standard-form contracts from industry associations such as the HIA or Master Builders, because those are maintained against current legislation. Where a regulated form applies to your job, use it. Your own template is best used for the commercial detail around it: scope, materials, access, hidden damage, warranties and the approvals trail.

The clauses a roofing contract template should contain

Whatever format you use, work through these sections in this order. Each one answers a question that otherwise becomes a dispute.

1. Parties, licence and site

Full legal names, ABN, your contractor licence number, the owner’s name and the exact property address. If the owner is not the person signing (a property manager or a tenant, for example), record their authority to approve the work. This is where a guided form helps: you ask for these details once and they flow into the document.

2. Scope of work

Describe what you are actually doing, in terms a stranger could check:

• Roof type and area (for example, remove and replace Colorbond roof sheeting over the main dwelling, in square metres)
• Materials by brand, profile and colour, so a substitution is a visible change
• Flashings, ridge capping, gutters, downpipes, sarking, insulation and anything else included
• What is excluded (solar panel removal, antenna and satellite dish relocation, fascia repairs)
• Access, scaffolding or edge protection, and waste removal

The test for a good scope is simple: if a different roofer picked it up, would they price the same job? If not, it is too vague. We cover the structure in more detail in our guide to contractor scope of work.

3. Price: fixed or cost-plus

State the contract price and whether it is fixed. Industry commentary strongly favours fixed price for residential work, because cost-plus gives the owner no certainty and tends to cause arguments when the final invoice lands. The Buildana checklist makes the same point: a fixed price should come with clear rules for what happens to the cost of unknown conditions.

That is the key phrase. A fixed price is only fair to you if the contract says which risks sit outside it.

4. Hidden damage and unknown conditions

This is the clause that separates a professional roofing contract from a generic building template. Roofers regularly discover rotted battens, damaged decking or termite-affected timber only after stripping the old roof. Rather than leaving it open, build a rate into the contract:

• A pre-agreed price per sheet, per metre or per rafter for replacing damaged timber
• A clear statement that any extra work needs the owner’s written approval before it starts
• A photo of the damage attached to that approval, taken from the roof
• A note of the effect on the total price and the completion date

The owner then knows the worst case before they sign, and you are not asking for money on a Thursday afternoon with the roof open to the sky.

5. Variations

Variations are the most common cause of payment disputes in building work. The NSW Building Commission has been clear that changes to scope must be agreed in writing before the work is carried out. A text message saying “yep, go ahead” is not a safe substitute.

A workable variation clause says:

1. Any change to scope, materials or timing must be recorded on a variation form.
2. The form states the work, the price change and the effect on the completion date.
3. Both parties sign before the work proceeds.
4. The signed variation is attached to the contract and counts as part of it.

If you want to see how this works in practice, the same principle underpins our piece on staged payment approvals in construction. Cost blowouts often start with unrecorded changes, a theme explored in this article on construction cost overruns, which is worth reading if your jobs regularly finish above the original number.

6. Payment schedule and deposit

Tie payments to progress, not the calendar. The Buildana checklist recommends a schedule linked to construction milestones rather than dates, and that suits roofing well. A typical shape for a re-roof might be:

Do not copy a deposit percentage from a website. Limits are set by state law and differ, so look up the maximum for your state and write it into the template as a fixed figure you have checked.

7. Timing and weather

Give an estimated start and completion, and say what counts as a reasonable delay: rain, high wind, late material delivery, access problems. Avoid promising a firm date you cannot control. A weather clause protects you, and the owner prefers it to a surprise.

8. Insurance, safety and insurance-claim work

State the insurance you carry. If the job follows storm or hail damage and the owner is claiming through their insurer, say clearly who is responsible for dealing with the insurer, what happens if the claim is partly approved, and whether the owner owes you the full contract price regardless. Never leave this as an assumption.

9. Warranties

Keep two warranties apart:

• Workmanship warranty: yours. State the period, what it covers (leaks caused by installation, for instance) and what voids it (unauthorised modifications, lack of maintenance).
• Manufacturer’s product warranty: the supplier’s. For Colorbond steel, for example, the terms and conditions belong to the manufacturer, not to you.

Blurring the two creates confusion and exposure if a material fails despite good installation. Name both, state who handles each claim and attach the supplier’s warranty document.

10. Completion, defects and sign-off

Finish with a completion form: the owner inspects, lists any defects, and signs to confirm practical completion. A signed completion record is your evidence that the job was accepted, and it is the trigger for the final payment.

11. Dispute resolution and signatures

Include a simple escalation path (discussion, written notice, then the state’s fair trading or building regulator process) and the signature block for both parties, with date and time. Add your state’s mandatory notices, such as consumer building guide acknowledgements where they apply.

A sample flow, from enquiry to signed roof job

Here is how the pieces fit when a customer rings after a storm.

1. Enquiry form. The customer enters their address, roof type, photos of the damage and whether an insurance claim is open.
2. Site inspection. You measure up, photograph the roof and note any suspect timber.
3. Contract generated. Scope, materials, price, hidden-damage rates and the payment schedule fill in from your template.
4. Signature and deposit. The owner reads, signs on their phone and pays the deposit.
5. Mid-job variation. If strip-off reveals rotted decking, you send a variation with a photo and the pre-agreed rate. The owner signs before you proceed.
6. Completion. The owner signs off, you issue the final invoice and the warranty documents.

Each step produces a record. If anything is questioned in a year’s time, you hold the signed contract, the photos and the timestamps.

Perspective: why we build the contract from the form

Most e-signature tools start with a finished PDF. That works if your contract is already drafted, but for a roofer, the contract is the last step in a chain that starts with the customer’s answers: address, roof type, access, insurance status, materials chosen. When those answers are typed into a separate quote, then retyped into a Word file, then emailed, errors creep in, and each handover is a place where integrity can be lost.

We design KSign around the whole sequence: form, contract, signature, payment. The details the customer enters generate the agreement directly, the signature is captured electronically, the deposit can be collected in the same flow, and the signed document is stored with an audit trail. That trail matters for trust: it gives you verifiable evidence of who signed what, and when, which is the practical meaning of non-repudiation for a small business.

Our view on templates is plain. Use the regulated or association form where your state requires it, add your own clauses for hidden damage, variations and warranties, and make sure every change is signed before work proceeds. A template does not protect you if it sits in a folder. It protects you when the customer actually signs it.

Signing the contract online

A roofer is often on a ladder or in a ute when the customer is ready to say yes. Mobile signing removes the wait. Check that your process:

• Works on a phone without the customer installing anything
• Captures a timestamp and a record of the signing
• Stores the signed contract, variations and completion forms in one place
• Lets you take the deposit at the point of signing

If you want this set up around your own roofing template, KSign’s contract automation turns form answers into a finished agreement, and embedded payments let the owner pay the deposit as part of signing. Plans are listed on the pricing page: Standard is A$24 per seat per month and Professional is A$40 per seat per month, while Enterprise has no published price.

If you work across trades, our related guides for painting contracts, electrician contracts and subcontract agreements follow the same logic, and the subcontract piece is useful if you bring in crews for larger re-roofs.

Common mistakes to avoid

• Vague scope. “Replace roof” is not a scope. List materials, areas and exclusions.
• No hidden-damage rate. Leaving this open invites a fight halfway through the job.
• Verbal or text variations. Get a signature before the work, not after.
• Calendar-based payments. Tie them to milestones so the money tracks the work.
• One warranty paragraph for everything. Split workmanship from product.
• Copying a template from overseas. A US form will not reflect Australian state requirements, and an Australian one will not meet a US state’s rules. Check where the work is performed.
• Ignoring the regulated form. If your state requires a specific contract or consumer guide above a threshold, attach it.

FAQ

Do I need a written contract for a small roof repair?

In most Australian states you should assume yes. Consumer Affairs Victoria says a written contract is vital for home repairs, regardless of the amount, and NSW guidance says all contracts must be in writing. Thresholds and mandatory forms differ by state, so confirm with your regulator before relying on an exemption.

Should a roof replacement contract be fixed price or cost-plus?

For residential work, fixed price is generally the safer choice because the owner knows the total and you avoid disputes over the final invoice. To keep a fixed price fair to you, add a hidden-damage rate and a signed variation process for anything outside the scope.

How do I handle rotted timber found after the old roof comes off?

Price it in the contract in advance, per sheet or per metre, and require the owner’s written approval, with photos, before any extra work starts. This protects both sides and keeps the job moving.

Can a customer sign a roofing contract on their phone?

Yes, electronic signing is commonly used for trade contracts, and it suits roofing because the owner can sign from anywhere. Choose a tool that records a timestamped audit trail and stores the signed copy, and check that any state-mandated forms are included in the signing pack.
