You've done the job. The roof is fixed, the site is clean, and you've sent the invoice. A week later — nothing. You chase by text. Then by phone. You get told they'll sort it at the weekend. The weekend passes. Three weeks after completion you still haven't been paid, and you've got wages to cover and materials to buy for the next job.
This is not an unusual situation for roofing contractors in the UK. It's one of the most common business problems in the trade — and one of the most damaging to cashflow, morale, and the long-term health of a small business. The good news is that most late payment problems are entirely preventable with the right systems in place upfront. And for the ones that do happen despite your best efforts, there is a clear, professional escalation process that gets results without burning bridges unnecessarily.
This guide covers the prevention, the chase sequence, the legal options, and the mindset shift that most roofers need to stop being paid late as a matter of course.
Part One: Prevention — Setting Up to Get Paid on Time
The time to solve a payment problem is before the job starts, not after it finishes. These are the systemic changes that dramatically reduce late payment incidents.
Always take a deposit
A 25–40% deposit before any work begins is standard practice in the roofing trade and every homeowner should expect it. It covers your material costs, confirms genuine intent to proceed, and creates financial commitment. A customer who refuses a reasonable deposit is a customer who may not pay the balance either.
Set payment terms in writing before the job
Your written quote should state the deposit amount, the balance due date (e.g. "balance payable on day of completion"), and accepted payment methods. A customer who has agreed in writing to your payment terms has no legal defence for non-payment on those terms.
Invoice the same day the job is completed
Every day between job completion and invoice delivery is a day of psychological distance from the work — and the customer's gratitude fades with it. Send the invoice by WhatsApp or email the same day, while the satisfaction is fresh and the completed job is visible. State the due date explicitly.
Make payment as easy as possible
Include your bank sort code and account number on every invoice. If you can accept card payments (via SumUp, Square, or iZettle) offer that option — many customers find card payment far more convenient than bank transfer. The easier you make it to pay, the faster you get paid.
Agree milestones on larger jobs
For jobs running more than two or three days, structure payment as milestones: deposit, mid-job payment, and balance on completion. Never allow a large unpaid balance to build up over several days of work — the longer the invoice grows, the harder it becomes to collect.
Send completion photos with the invoice
Sending before and after photos of the completed work with your invoice documents the quality of the job and removes any ambiguity about whether it was completed to standard. Customers who have seen photographic evidence of excellent work are less likely to use vague "quality concerns" as a pretext for withholding payment.
❌ Payment setup that invites problems
- No deposit — starting work on trust alone
- No written payment terms — verbal agreement only
- Invoice sent days after completion
- Invoice by text — no formal document
- Only accepting cash or bank transfer
- No due date on invoice — just "payment on receipt"
- No staged payments on large jobs
✅ Payment setup that protects you
- 25–40% deposit received before work starts
- Payment terms written in the accepted quote
- Invoice sent same day as completion
- PDF invoice with bank details and explicit due date
- Card payment option available
- Specific due date stated — e.g. "due by [date]"
- Milestone payments agreed on jobs over 3 days
Part Two: The Chase Sequence — What to Do When Payment Is Late
Even with the best systems in place, some invoices will still run late. Having a defined, consistent chase sequence removes the emotion from the process — you're not being aggressive or unreasonable, you're simply following a professional process that you apply to all late accounts.
WhatsApp or phone call on the due date
Don't wait for payment to be late before making contact. On the day the invoice is due, send a brief WhatsApp message confirming the invoice is due today and asking if they need anything from you to process it. Most people simply forget — a prompt reminder resolves the majority of late payments immediately.
Email with invoice attached
If the day 1 reminder produced no payment, send a follow-up email seven days after the due date. Attach the invoice again — some people genuinely lose emails or delete them accidentally. Keep the tone professional and assume good faith at this stage. State the new date by which you would like payment.
Hi [Name],
I'm following up on invoice [number] for £[amount], which was due on [date] and remains outstanding. I've attached a copy in case the original has been missed.
Please arrange payment by [date 7 days from now]. If there is anything preventing payment or if you have any queries about the invoice, please contact me directly so we can resolve it.

Formal payment demand by email and WhatsApp
Two weeks overdue and no payment response requires a firmer communication. The tone shifts from polite reminder to clear demand. State that the account is now significantly overdue, reference the agreed payment terms, mention that late payment interest may be applicable, and set a firm deadline of 7 days before further action is taken. Do not threaten legal action at this stage — state it as a factual next step if payment is not received.
Hi [Name],
Invoice [number] for £[amount], due on [original due date], remains unpaid despite two previous reminders. This account is now 14 days overdue.
Under our agreed payment terms, I am entitled to charge statutory late payment interest on this amount. I have not yet added this to the invoice but reserve the right to do so.
Please arrange payment of £[amount] in full by [date 7 days from now]. If payment is not received by this date, I will have no choice but to pursue recovery through the courts without further notice.
If there is a genuine reason for the delay, please contact me immediately to discuss. I would prefer to resolve this without formal action.

Formal letter before court proceedings
A letter before action (LBA) is the formal legal step required before you can issue court proceedings in England and Wales. It must be sent before you file a claim. Send this by email and by recorded post — recorded post creates an undeniable delivery record. Give 14 days for a response. After this point, if payment is still not received, you proceed to court.
Dear [Full name],
RE: Unpaid Invoice — [Invoice number] — £[Amount]
I write to notify you formally that the sum of £[amount] remains outstanding in respect of roofing work carried out at [address] on [date of completion], as detailed in invoice [number] attached.
Despite reminders on [dates], payment has not been received. This letter constitutes formal notice that unless payment in full is received within 14 days of the date of this letter, I will commence proceedings in the County Court to recover the debt, together with court costs and interest under the Late Payment of Commercial Debts (Interest) Act 1998 or the County Courts Act 1984 as applicable.
Payment should be made to: [Bank name, sort code, account number]
If you dispute the debt or believe there are any issues with the work carried out, please contact me within 14 days so I can address your concerns. If I do not hear from you within this period, proceedings will be commenced without further notice.
Yours faithfully,
[Your name and signature]
[Business name, address, phone, email]
Small Claims Court (Money Claims Online)
If the letter before action produces no payment, you file a claim online. For debts under £10,000 in England and Wales, use Money Claims Online at gov.uk/make-court-claim-for-money. The process requires no solicitor, the fees are modest, and the court fee is recoverable if you win. A county court judgment (CCJ) against the debtor significantly affects their credit rating — most people pay well before a judgment is entered.
Your Legal Rights: What UK Law Says
UK law gives roofing contractors clear rights when it comes to unpaid invoices. Understanding them helps you act with confidence rather than uncertainty.
| Legal Right | What It Means | How to Use It |
|---|---|---|
| Right to payment on agreed terms | If the customer agreed to your payment terms in writing (quote acceptance), those terms are legally binding | Always get written acceptance of your quote — even a WhatsApp reply saying "yes, go ahead" is legally valid |
| Late payment interest (commercial debts) | Under the Late Payment of Commercial Debts Act, you can charge 8% above base rate on overdue commercial invoices | State in your terms that statutory late payment interest applies. For residential customers, include a clause in your T&Cs before the job begins |
| Debt recovery costs | For commercial debts over £10,000 you can claim £100 recovery costs; over £100,000 you can claim 2.5% of the debt value | Include these in your claim if pursuing a commercial customer through the courts |
| Small Claims Court (under £10,000) | You can file a money claim online without a solicitor for debts up to £10,000 in England and Wales | Use Money Claims Online at gov.uk/make-court-claim-for-money after sending a letter before action |
| County court judgment (CCJ) | A judgment entered by the court against the debtor remains on their credit file for 6 years unless paid within 30 days | Apply for a CCJ if the claim is undefended or won. Most debtors pay before this stage to protect their credit rating |
When a Customer Raises a Dispute to Avoid Paying
A common tactic from customers who simply don't want to pay is to raise a dispute about the quality of work after the invoice arrives — particularly when no complaint was raised during or immediately after the job. This is not always dishonest; sometimes a problem genuinely appears later. But it is sometimes used as a pretext to withhold payment indefinitely.
The best protection is documentation:
- Before and after photos taken on the day of completion — provide undeniable evidence of work quality at the point of completion
- A written sign-off message from the customer on completion day — even a WhatsApp reply saying "looks great, thanks" provides a record of satisfaction at that time
- A clear scope of work in the original quote — defines exactly what was and was not included, preventing "but I thought you were doing X" disputes
- A workmanship guarantee in writing — shows that if there is a genuine defect, you are willing to return and address it. Separating the legitimate remedy from the payment obligation is important: a genuine defect is addressed under guarantee; it does not entitle the customer to withhold the full invoice amount
If a dispute is raised, respond to it in writing, acknowledge the complaint, and offer to inspect and resolve any genuine issues — but state clearly and in writing that this does not suspend the payment obligation and that the invoice remains due.
The Mindset Shift Most Roofers Need
Many roofing contractors feel uncomfortable chasing payment. They don't want to come across as aggressive. They worry about damaging the customer relationship. They give customers the benefit of the doubt for weeks longer than is warranted.
This reluctance is understandable but costly. The mindset shift is this: you are not doing anything aggressive or unreasonable by expecting to be paid for work you have done, on the terms that were agreed. The customer is the one behaving unreasonably by not paying. Your professional, systematic chase process is not harassment — it is the reasonable expectation of any business that has delivered what was promised.
A roofer who communicates clearly, follows up promptly, and pursues debts systematically gets paid faster and is taken more seriously than one who chases sporadically and backs down when a customer is non-responsive. Professionalism in payment collection is a sign of a well-run business, not aggression.
- ✓ Set up a standard quote template that includes payment terms — deposit amount, due date, accepted methods
- ✓ Never start a job without a deposit being received and cleared
- ✓ Send the invoice on completion day — not the following week
- ✓ Follow up on the due date — don't wait for payment to be missed
- ✓ Take before and after photos on every job and attach them to the invoice
- ✓ Use a defined chase sequence — Day 1, Day 7, Day 14, Day 21 — and stick to it
- ✓ Follow through on threatened action — empty threats are counterproductive
- ✓ Know your rights — the Small Claims Court is simpler and more accessible than most people assume
Frequently Asked Questions
What can a roofing contractor do if a customer doesn't pay?
Start with a polite reminder by WhatsApp or phone on the due date. If that doesn't produce payment, follow up with a formal written demand by email within 7 days. After 14 days overdue, send a firm demand referencing your right to charge late payment interest. At 21 days overdue, send a letter before action stating your intention to commence court proceedings within 14 days. For debts under £10,000, use Money Claims Online at gov.uk without needing a solicitor.
How can roofers prevent slow payment from customers?
The most effective prevention measures are: taking a 25–40% deposit before starting work; agreeing clear payment terms in writing before the job begins; sending the invoice on the day the job is completed; making payment easy with multiple options including bank transfer and card; and following up proactively on the due date rather than waiting for payment to be missed. Documentation — photos, written quote acceptance — also helps resolve any disputes quickly.
Can a roofing contractor charge interest on a late payment?
Yes. Under the Late Payment of Commercial Debts (Interest) Act 1998, businesses can charge statutory interest on overdue commercial invoices at 8% above the Bank of England base rate. For residential homeowner customers, include a late payment clause in your terms and conditions before the job begins. Always state payment terms and any late payment charges clearly in your quote and invoice.
Is the Small Claims Court worth using for an unpaid roofing invoice?
Yes, for debts between approximately £500 and £10,000 it is often worth using. The process can be completed online without a solicitor via Money Claims Online at gov.uk. Court fees are modest and are recoverable if you win. Most debtors settle before a judgment is entered — the existence of court proceedings and the threat of a CCJ on their credit file is sufficient motivation for the majority. Always send a letter before action first and allow 14 days for a response before filing.
Should a roofer use a contract for every job?
Yes. Even a simple one-page written agreement — or a detailed written quote accepted in writing — setting out the scope of work, price, payment terms, and deposit amount gives you legal standing if a customer refuses to pay. Without written terms, pursuing unpaid invoices is harder as it becomes a disputed verbal agreement. A WhatsApp message from the customer accepting your quote in writing is legally valid and provides an adequate paper trail for most small claims situations.
