What you need to know about hiring a roofer in Caerphilly
Your roof is one of the most important parts of your home. When something goes wrong — whether it's a leak, missing tiles, or damage from weather — you need someone you can trust to fix it properly without ripping you off.
Finding a good roofer in Caerphilly doesn't have to be a headache. This guide walks you through what to expect, what you should pay, and the key questions to ask before you hire anyone.
Roofing work ranges from simple repairs that take a few hours to full replacements that take days. The type of work you need, the condition of your roof, and the materials involved all affect the price and how long the job takes.
One thing to remember: the cheapest quote isn't always the best deal. A roofer who cuts corners now will cost you thousands more in repairs down the line. What you're really paying for is quality work, proper materials, and someone who'll stand behind their job if something goes wrong.
Before you get any quotes, it helps to understand the basics. This guide covers the typical costs you'll see in 2026, the accreditations that matter, what's specific about Caerphilly homes, and exactly what you should ask any roofer who shows up to give you a quote.
What roofers in Caerphilly cost
Roofing costs in Wales have stayed broadly steady, but material prices do move around. Here's what you're likely to pay in early 2026.
For small repairs — fixing a few slipped tiles, clearing gutters, or patching a leak — expect £200-£600. These are usually half-day jobs, sometimes less. Call-out fees vary; some roofers charge £60-£150 just to come out and look at the problem.
Re-tiling a section of roof (say, replacing 20-30 tiles after storm damage) runs £800-£2,500 depending on the tile type and how hard they are to access. Welsh slate tiles cost more than standard clay or concrete tiles, and if your roofer has to work from difficult angles, the labour cost goes up.
A full roof replacement on a typical semi-detached house in Caerphilly — stripping old tiles, replacing damaged timber, and laying new tiles — costs £6,500-£15,000. Detached houses run £9,000-£18,000. These prices assume standard asphalt shingles or concrete tiles. If you want slate, expect 30-50% more.
Flat roof repairs and recovers run £1,200-£4,000 for a small area. A full flat roof replacement on a 50-60 square metre section costs £3,500-£7,000 for felt or bitumen systems.
Don't forget scaffolding. If your roof is steep or your house is tall, the roofer needs to hire temporary platforms. This adds £400-£1,200 to the job, depending on how long they're needed.
Always get at least three written quotes. A good roofer will explain what materials they're using and why, and they'll break down labour and materials separately.
Accreditations and qualifications that matter
When you're looking at roofers, certain qualifications tell you they've been trained properly and work to a standard.
The National Federation of Roofing Contractors (NFRC) is the biggest trade body in the UK. If a roofer is NFRC-registered, they've passed safety and competency checks, they carry proper insurance, and they work to a code of conduct. If something goes wrong, you have recourse. Look for the NFRC logo on their website or ask to see their membership card.
RoofCERT is another key accreditation. It's a certification scheme run by the NFRC and covers training in different roofing types — tiles, slates, flat roofs, lead work — and guarantees the roofer has the right knowledge for the job. If you need specialist work like slate or lead, check they're RoofCERT-qualified for that material.
Safety-wise, your roofer should hold a valid CSCS card (Construction Skills Certification Scheme) or equivalent, and they should be able to talk through their method for working at height safely. They should also have liability insurance of at least £1 million and public liability insurance.
Look for roofers who offer a written guarantee on their work — usually 5-10 years for labour. This means if the roof leaks within that period due to their poor workmanship, they'll fix it for free.
Be cautious of roofers who won't give you accreditation details or get evasive about insurance. It's not about being difficult; it's about protecting your home and your money. A qualified roofer will have this information to hand and won't mind you asking.
What's specific about roofs in Caerphilly
Caerphilly's housing stock is dominated by Victorian and Edwardian terraces, semis, and post-war estates. These older homes have solid roofs that, if maintained, last well — but they're prone to specific problems.
The valleys between roof sections (where two pitches meet) are common leak points in older terraces. Rainwater gets trapped here, and if the original mortar or flashing has cracked, water seeps in. You'll notice damp patches on the ceiling near the top of the walls. A lot of Caerphilly roofers are used to dealing with this.
Wind damage is common around here. Caerphilly isn't coastal, but it sits on higher ground and catches weather coming up from the south and west. Slipped tiles and loose flashings are regular problems, especially in winter storms. If you've had gales through, it's worth getting a surveyor up to check for damage — sometimes it's not obvious from the ground.
Roof timbers in pre-1950s homes are often softwood that's never been treated. Wet rot and woodworm can be hiding under tiles. A good roofer will flag this when they're up there. If you ignore it, the timbers eventually fail and your whole roof structure is at risk. Replacing rotten timbers adds £2,000-£5,000 to the job, but it's essential.
Many Caerphilly properties still have original Welsh slate roofs. These are beautiful and durable — properly laid slate lasts 100 years — but repairs need someone who knows slate. Standard roofers might not. If your roof is slate, specifically ask whether your candidate has experience with it.
The Caerphilly Council area has been pushing for energy efficiency improvements. If you're replacing a roof, consider adding insulation while you're at it — this ties in with any council grants you might be eligible for.
How to hire a roofer in Caerphilly
Start by asking for recommendations. If you know neighbours or friends who've had roof work done, ask who they used and whether they were happy. Word of mouth is still the most reliable way to find a decent trader.
Next, search online for local roofers. Use directories like Best Trades Wales, Google Maps, and Trustmark. Look at reviews — not just the star rating, but what people actually say. If reviews mention clarity on pricing, keeping to schedules, and tidying up after, that's a good sign.
Draw up a shortlist of three to five roofers. Call them or submit an enquiry through their website. Be clear about what you need: "Small roof repair to three tiles" or "Full roof replacement" and your address. A good roofer will arrange a time within a few days.
When they come to quote, watch how they work. Do they actually get on the roof and inspect it properly, or do they give you a price from the ground? Do they listen to what you're saying, or do they just try to upsell you? A roofer who takes time to understand your problem and explains what needs doing is worth hiring.
Get written quotes from all three. Compare them side by side — not just the total, but the breakdown. If one quote is much cheaper than the others, ask why. Is it lower labour rates, cheaper materials, or something else? If they can't explain the difference, that's a red flag.
Once you've chosen, agree on a start date, payment terms, and what happens if the weather delays the work. Most roofers ask for a deposit (usually 25-50%) upfront and the balance on completion. Never pay the full amount before the job is done.
Six questions to ask before you hire
Before you agree to anything, ask your roofer these questions.
Are you NFRC-registered or RoofCERT-qualified? Ask them to show you proof. If they're not, ask why. Some smaller traders aren't registered, but if you're paying for a significant job, you want the assurance that comes with proper accreditation.
Can you give me references from jobs you've done in the last two years? A good roofer will happily provide names and phone numbers of recent customers. Ring them and ask: did the roofer start and finish on time, were they tidy, did they stand behind the work if issues came up after?
What's your guarantee on labour, and what does it cover? A 5-10 year guarantee on workmanship is standard. Check whether it covers leaks caused by poor installation or just structural failure. Get it in writing.
What materials are you using, and why? If they're recommending a particular tile, flashing, or underlayment, they should explain why it's suitable for your roof and your area. "Because it's cheaper" isn't a good enough reason.
How long will the job take, and what happens if the weather delays it? Bad weather — rain, high winds, frost — stops roofers working. A professional will have a contingency plan. Avoid roofers who guarantee completion on a fixed date with no mention of weather.
What happens if I'm not happy with the work? Do they come back to fix issues for free during the guarantee period? Are there any exclusions? Get this in writing so you're both clear.
If a roofer gets irritated by these questions or tries to rush you, hire someone else. You're about to trust them with your home.
