Knowing when to expand your roofing crew comes down to three things: consistent lead flow, cash reserves that can cover an extended payroll, and clear signs your current team is at capacity. When all three line up, waiting costs you more than hiring does.
Last reviewed June 2026. Updated with current UK roofing labour figures, NFRC 2025 recruitment data, and a plain-English decision framework for roofing business owners thinking about taking on more staff.
Running a roofing business in the UK means managing a workforce under near-permanent pressure. There are around 12,016 roofing businesses operating in the UK as of 2025 (IBISWorld), and the sector’s market size has reached roughly £7.3 billion. Inside that, the single biggest brake on growth isn’t lack of work… it’s lack of skilled people to do it.
Why most roofing companies get the timing wrong
The usual pattern: you’re slammed in spring, panic-hire two lads, then spend October wondering how to keep them busy. The opposite happens too… you hold off, burn out your best crew, and watch enquiries slip to the competitor who could actually book them in. Neither works. What you need instead is a small set of measurable signals that tell you, before you’re in crisis mode, that it’s time to move.
The skills shortage makes this more urgent. According to the NFRC’s Autumn 2025 State of the Industry report, 70% of roofing firms said recruitment difficulties are limiting their ability to take on work… a 5% rise from summer 2025 (Roofing Today / NFRC). The most difficult roles to fill: tilers, slaters, and built-up felt roofers. That means the window for hiring good people is narrower than it was, so being ready to move quickly when the signal appears matters more than it used to.
Five clear signals it is time to expand your crew
1. You are regularly booking more than three weeks out
A two-to-three-week lead time during peak season is normal and healthy… it signals demand and keeps the pipeline full. When you are consistently beyond three weeks, you are losing customers who need the work done sooner. They call two more companies, get booked in faster, and you never hear from them again. Track your average booking window each month. If it stays above three weeks for two months running, that is a capacity signal, not a seasonal blip.
2. You are turning away profitable work
Turning away a genuinely poor-fit job is good judgement. Turning away profitable, well-priced roofing work because you simply cannot schedule it is a different problem… it is a capacity problem. Keep a count of how many enquiries you decline each month because of bandwidth. If it is more than three or four during peak months, the revenue you are leaving behind likely exceeds what an additional pair of hands would cost.
3. Your best roofer is showing signs of burnout
Your skilled, experienced crew member is your biggest asset. When they are logging excessive hours… above 48 hours per week consistently, which is the Working Time Regulations upper limit under UK law (GOV.UK)… quality slips and the risk of errors or injuries rises. Snagging rates going up, completion times creeping out, or a normally steady person becoming short-tempered: these are signals your team is stretched, not signals they need a pep talk.
4. Subcontractor spend has become a permanent fixture
Using CIS subcontractors for overflow is a sensible flexible option. But there is a tipping point. A self-employed roofer sub typically charges £200–£275 per day (Checkatrade), and if you are relying on subs consistently for two or more months to cover a steady volume of work, you are likely paying a premium above what an employed roofer or regular team member would cost. If sub spend is a permanent line on your P&L rather than occasional cover, the maths often favours employment.
5. Revenue has plateaued despite a full enquiry pipeline
If your enquiry volume is steady or growing but your completed jobs and monthly revenue are flat, you have hit a physical capacity ceiling. The business can only turn around what the crew can physically complete. No amount of quoting or marketing will move that number… only more output from more trained hands will. When your revenue has stalled for three or four consecutive months despite the phone continuing to ring, you have your answer.
What to check before you commit to hiring
Seeing the signals is one thing. Being ready to act on them is another. Hire too soon and you are carrying payroll through a slow patch. Get these four foundations right first.
Stable lead flow over 90 days, not just the next fortnight
An expansion decision should be based on what your pipeline looks like over the next three months, not what is busy right now. If you cannot see 60–90 days of work ahead for an expanded team, you are not ready. This is where local visibility matters directly… when your roofing business appears consistently in local search and on Google Maps, the pipeline is more predictable. It is part of the work we do with trades businesses to give owners exactly that kind of forward visibility.
Cash reserves to cover eight weeks of expanded payroll
A new roofer employed on a UK average salary of around £28,000–£35,000 a year (Reed.co.uk) represents a fixed cost that arrives every month regardless of weather, materials delays, or slow customers. Before you commit, ensure your cash reserves could sustain that payroll for at least eight weeks from your current bank balance, without needing new invoices to clear first.
Documented job processes a new person can follow
A new roofer paired with an experienced crew member can come up to speed quickly. One dropped in without clear processes just adds questions and slows the whole team down. Before hiring, document your standard job workflow: materials order checklist, site set-up, completion and sign-off, follow-up review request. It does not need to be a 40-page manual… a set of simple checklists is enough.
A clear break-even point for the new hire
Know your numbers. If a typical residential re-tile job brings in £4,000–£7,000 for a terraced house or £8,000–£14,000 for a semi-detached (Checkatrade), and your crew currently completes two jobs a week… how many additional completed jobs per month does a new hire need to generate to cover their wage plus on-costs? Work that number out in advance. It removes guesswork from the conversation.
The expansion readiness check: a quick scorecard
Run through each signal and prerequisite honestly. If you can check most of them off, you are ready to move. If you cannot, you know what to fix first.
| Signal or prerequisite | Ready? | Weight |
|---|---|---|
| Booking window consistently above 3 weeks | Yes / No | Signal |
| Turning away profitable work most months | Yes / No | Signal |
| Best crew member showing burnout signs | Yes / No | Signal |
| Sub spend is a recurring, not occasional, cost | Yes / No | Signal |
| Revenue flat despite steady enquiry flow | Yes / No | Signal |
| 90-day pipeline is full | Yes / No | Required |
| 8 weeks of expanded payroll in reserves | Yes / No | Required |
| Job processes documented and followable | Yes / No | Required |
| Break-even calculation done | Yes / No | Required |
Three or more signals, plus all four required items checked: you are ready to start the hiring process now. Two signals and missing one required item: fix the gap first, then hire. Fewer than two signals: focus on filling the current team’s diary rather than adding to headcount.
What good expansion looks like in practice
Adding a person to a crew is not just about having another pair of hands on site. The practical side shapes whether the hire actually improves output or just adds cost and friction.
Pair new hires with your strongest crew member first
The fastest way to bring someone up to your standard is to put them alongside the person who already embodies it. Your most experienced roofer will find the arrangement temporarily slower… but the investment pays back within a few weeks once the new hire stops needing to ask about every step. Budget for about four to six weeks of slightly reduced output from that pairing before they run at full speed.
Keep your experienced team on the complex jobs
A standard re-tile on a straightforward pitched roof and a specialist heritage slate replacement with awkward access are not the same job. As you grow, the most effective division of labour is experienced crew on complex, higher-margin work… newer or developing team members on standard, repeatable jobs they can build confidence on. That approach protects quality on your most valuable contracts while building the wider team’s skills.
Scheduling two crews is a different job to scheduling one
Running a single crew means you know exactly where your team is. Two crews means two job sites, two sets of materials to order, two sets of customer communications to manage simultaneously. That operational step-up catches owners off guard. Build in time in your week for the coordination before you need it, not after. Many roofing owners find that even a basic CRM or job-management tool… something they could run from a phone… makes the difference between two crews running smoothly and a weekly scramble.
That kind of joined-up local marketing… reviews building your profile, visibility driving the enquiries, and AI-powered tools handling the follow-up… is what we help roofing businesses put in place. More on how roofers are using AI to save time on local marketing if that is relevant where you are.
What hiring too early actually costs you
Hiring before the prerequisites are in place is not a risk-free bet on the future… it is a real cost, right now.
An employed roofer on £30,000 costs you roughly £34,000–£35,000 once employer National Insurance contributions are added (13.8% on earnings above the secondary threshold, currently £9,100 per year under HMRC’s current rates: GOV.UK). If the pipeline does not support them full-time and they are standing idle for even two days a week, that is around £280–£380 in unproductive cost every week at typical roofer day rates. Over three months of a slow patch, that adds up to roughly £3,600–£5,000 in wages for work that was not there.
The risk during shoulder season is real too. Many roofing businesses expand confidently in spring and summer, then face a difficult question in November about whether they can sustain that headcount through winter. The answer to that question should be considered before you hire… not after.
Frequently asked questions
How many people should a roofing crew have?
For most residential pitched roof work, a crew of two to four is standard: a lead roofer and one or two labourers or apprentices. Larger or more complex jobs… full replacements, commercial contracts… may need five or six.
The right number depends on the type of work you take on, not a target headcount. A crew of three running efficiently on a steady diet of re-tiling and repair work will outperform a crew of five without clear roles and enough jobs to fill their time. Start with what your current jobs actually need, then scale from there.
Is it better to hire an employee or use subcontractors to grow?
Subcontractors under CIS give you flexibility without fixed payroll cost… useful for seasonal peaks or specialist work. Employed staff give you more control, consistency, and the ability to develop people to your standard.
A self-employed roofer sub typically charges £200–£275 per day, while an employed roofer at £30,000 a year costs you roughly £165 per day across a 46-week working year. If you have consistent year-round work, employment is usually cheaper and more controllable. If your work spikes seasonally, subs remain the practical flexible option.
What should I pay a new roofer in the UK in 2025?
UK roofer salaries range from around £25,000 for someone starting out to £35,000–£50,000 for experienced specialists, with London and the South East running 20–30% higher than other regions.
Apprentice roofers start at the apprenticeship minimum wage (£7.55 per hour from April 2025 in year one, rising to £12.21 once year one is complete: CITB). Experienced, qualified roofers command significantly more. Check current CITB apprenticeship grant rates if you are considering that route… CITB allocated £68 million in apprenticeship grants in 2025–26.
How do I keep a new crew member busy during the winter slow-down?
Plan for it before you hire: flat roof repairs, guttering, fascias, soffits, and emergency call-outs tend to hold up better through winter than large pitched roof replacements.
The businesses that manage headcount through winter most successfully tend to be those with a predictable review and repeat-customer pipeline… people who have already used you calling back rather than relying purely on cold enquiries. That is a marketing and visibility question as much as an operational one.
Do I need to register under the Construction Industry Scheme when I take on roofers?
If you take on subcontractors, yes: you need to register as a contractor under CIS and deduct tax at source before paying subs. If you employ roofers directly on PAYE, CIS does not apply but you handle PAYE and employer NI through payroll instead.
HMRC’s CIS guidance covers both routes clearly. If you are moving from solo subcontractor to running employed staff for the first time, speaking with an accountant before your first payroll run is worth the hour.
Will the skills shortage make it harder to find a good roofer to hire?
Yes, genuinely. The NFRC’s 2025 data shows 70% of roofing firms report recruitment difficulties… tilers, slaters and felt roofers are the hardest positions to fill.
What that means practically: advertise on trade-specific job boards as well as general ones, consider approaching CITB about apprenticeship routes, and don’t wait until you’re desperate to start the process. The average time from posting a roofing job to a qualified person starting on site is longer now than it was three years ago. Factor that lead time into your planning.
How does expanding the crew affect my insurance and public liability?
Adding employees or increasing the number of subcontractors you manage typically means notifying your insurer and reviewing your employers’ liability and public liability cover. Employers’ liability insurance is a legal requirement the moment you take on a direct employee in the UK.
Costs vary by turnover, number of staff, and type of work. Speak to your broker before the hire is confirmed… not after. A lapse in cover on an active job site is a serious risk.
How long does it take a new roofer to come up to speed?
An experienced roofer who already knows the trade but is new to your way of working typically needs four to six weeks to run at full speed. An apprentice or someone new to roofing will need considerably longer… typically 12–18 months before they are working independently at your standard.
Budget for reduced output during that settling-in period rather than expecting a new hire to immediately add net capacity from day one. The investment pays back, but the payback is not instant.
