The National Federation of Roofing Contractors (NFRC) is the UK’s largest roofing trade body — members must prove competence, hold insurance and follow a code, and membership is verifiable on the NFRC website. TrustMark is the government-endorsed quality scheme covering trades generally. Either is a meaningful signal; a logo on a van is not — check the register yourself. In Horsham, where a lot of work is on period and conservation properties, it’s also worth asking about specific experience with your property type, whether that’s Victorian slate, Horsham Stone or a post-war concrete-tile estate.
NFRC and TrustMark membership require contractors to demonstrate competence, hold public liability insurance and follow a published code of practice — all independently verifiable. — NFRC / TrustMark accreditation criteria
Some warning signs are consistent across the trade. Doorstep cold-callers — especially after a storm, when opportunists work an area — are best refused; legitimate local roofers with full order books don’t knock on doors. Demands for large cash deposits before any work are a red flag; a modest deposit to order materials on a big job is normal, large sums up front are not. Verbal-only quotes leave you no recourse if the job differs from what was discussed. Pressure to decide immediately usually signals someone managing their own cashflow. And a quote far below the others almost always means something is missing — cheaper materials, no scaffold, or extras added once work starts.
Before you hire, ask: Are you NFRC or TrustMark registered, and what’s your membership number? Can I see your public liability insurance certificate? Will the quote be written, itemised and fixed? What exact materials will you use — and will they suit my property and any conservation constraints? What guarantee do you offer, and is it in writing? Who does the actual work — you or subcontractors? A good roofer answers all of these without hesitation. Get three quotes on the same specification so you’re comparing like for like rather than being drawn to the cheapest number, which is rarely the cheapest job once it’s finished.
Three written quotes is the right starting point, but only if they’re comparing the same thing. A quote for concrete interlocking tile isn’t comparable to one for natural slate without knowing the difference in material, lifespan and warranty. Check each quote names the tile and underlay, specifies fixing to BS 5534, and includes scaffold, skip and disposal. Where specifications differ, ask each roofer to re-quote on a common basis. The right choice is rarely the cheapest or the dearest — it’s the one where you understand exactly what you’re getting, from a contractor you can verify and who put it all in writing.
A guarantee is only as good as the company behind it, so understand what you’re being offered. A workmanship guarantee covers the roofer’s labour — ours is 10 years, in writing. A manufacturer’s product warranty covers the tiles or membrane and is separate. Beware very long ‘guarantees’ from firms unlikely to still exist to honour them, or guarantees that aren’t written down. Ask: is the guarantee in writing, what exactly does it cover, and is it insurance-backed so it survives if the company doesn’t? An insurance-backed guarantee protects you even if the roofer ceases trading — a meaningful difference on a major re-roof. In Horsham’s market, a verifiable local firm with a written, insurance-backed guarantee is worth more than a bigger number from an unknown.

There’s a real advantage in choosing a roofer genuinely based in and around Horsham rather than a national outfit or a traveling crew. A local firm knows the housing stock — which estates suffer nail sickness, where Horsham Stone and slate need matching, how the conservation areas are controlled. A local firm is verifiable: you can check their reviews from real Horsham addresses, their NFRC registration, and their track record in the area. A local firm is accountable — they rely on reputation and repeat work in a town where word travels, so they can’t afford to do a poor job and disappear. And a local firm is there afterwards if a guarantee is ever called on. When you’re comparing quotes, weigh a verifiable local reputation as heavily as the price — it’s the best predictor of how the job will actually go.
"Read their guide before getting quotes and it saved us from a doorstep cold-caller. Ended up using them — straight and honest."
"Actually explained what to check rather than just selling. Gave us an itemised written quote like they said everyone should."
"Only firm that showed us their NFRC number and insurance without being asked. That’s why we chose them."
Start by verifying trade-body membership on the official register rather than trusting a logo on a van — NFRC (National Federation of Roofing Contractors) and TrustMark both let you check a firm’s membership number online, and both require proven competence, insurance and a code of practice. Then ask to see a public liability insurance certificate (at least £2m, ideally £5m) and get everything in writing. A legitimate local roofer provides all of this without hesitation. Reviews from real local addresses that describe specific jobs are another good signal. Our guide to the best roofing contractors in Horsham covers what to look for.
Not automatically. A quote far below the others usually means something is missing — cheaper materials substituted once the scaffold’s up, no scaffold at all where it’s needed, or extras added mid-job. The way to compare fairly is to get three written quotes on a like-for-like specification: the same tile and underlay, the same fixing standard, the same scope. Then the cheapest genuinely-comparable quote is fine to choose. The cheapest headline number rarely turns out to be the cheapest finished job, because the savings are usually hidden in what’s been left out. Comparing specifications, not just prices, is the key.
Rarely, and you should be very cautious. Legitimate local roofers with full order books don’t cold-call door to door, and the doorstep approach spikes after storms when opportunists work an area targeting worried homeowners. The classic pattern is an ‘urgent’ problem spotted from the road, pressure to decide immediately, and a demand for cash up front — all red flags. If someone knocks unprompted claiming your roof needs urgent work, don’t agree anything on the spot; get an independent quote from a verifiable local firm. Genuine roofers are happy to give you time to check them out.
A modest deposit to order materials on a large job — a re-roof, say — is normal and reasonable. Demands for large cash sums up front are a red flag, and you should never hand over big cash payments before work starts. On most jobs, payment is staged: a small deposit, perhaps a milestone payment on a large project, and the balance on satisfactory completion. A contractor insisting on more than half before starting, or wanting the whole amount in cash, is telling you something about how they operate. Traceable payment against a written quote protects you.
A proper written quote names the exact materials (the specific tile and underlay), states the fixing standard (BS 5534 for slating and tiling), sets out the full scope of work, includes scaffold and waste disposal, gives a fixed price rather than an estimate, states payment terms, and specifies the guarantee. If any of these are missing — especially a vague ‘supply and fit new roof’ for a round-number price — ask before signing, because that vagueness is what lets cheaper materials be substituted later. A detailed written quote is also what lets you compare firms like for like.
NFRC and TrustMark are the meaningful ones. The NFRC is the UK’s largest roofing trade body — members must demonstrate competence, hold insurance and follow a code of practice, all verifiable on the NFRC register. TrustMark is the government-endorsed quality scheme covering trades generally. Either is a genuine signal; a logo alone is not, so check the membership number on the official register yourself. For Horsham work specifically, it’s also worth asking about experience with your property type — Victorian slate, Horsham Stone or a post-war concrete-tile estate each need different expertise.
In Horsham, yes — the district’s period and conservation stock needs specific experience and materials that general roofing doesn’t cover. Victorian slate, reclaimed Horsham Stone, lime mortar and traditional leadwork are all specialist skills, and a botched heritage re-roof using the wrong material or hard cement mortar damages irreplaceable fabric and can devalue the property. Conservation areas and listed buildings also bring consent requirements a general roofer may not handle. Ask specifically about experience with your exact property type. Our heritage roofing page and conservation area guide explain what’s involved.
Three written quotes on a like-for-like specification is the right number — enough to compare fairly and spot an outlier (too cheap usually means something’s missing; too dear may mean over-specification), without endless delay while your roof waits. The key is that all three quote the same materials, scope and standards, so you’re comparing genuine value rather than being drawn to the lowest number. If the specifications differ, ask each roofer to re-quote on a common basis. Then choose the firm you understand fully and can verify, not simply the cheapest.
Yes — if it covers the same specification as the others. A genuinely competitive price on identical materials, scope and standards is fine and worth taking. What isn’t safe is a cheap price achieved by cutting corners: thinner or substituted materials, skipped scaffold, shallow preparation, or extras added once work is under way. The only way to know which you’re looking at is a detailed written quote you can compare line by line against the others. Cheap-because-efficient is good; cheap-because-something’s-missing is expensive in the end.
A good quote is written, itemised and fixed: it names the exact tile and underlay, specifies fixing to BS 5534, includes scaffold, skip and disposal, states payment terms, and sets out the guarantee. A bad quote is a vague ‘supply and fit new roof’ for a round-number price, verbal-only, or one that leaves the materials unspecified — all of which leave room to substitute cheaper products or add extras once the scaffold’s up. The detail isn’t bureaucracy; it’s what protects you and lets you compare firms fairly. If a quote is vague, ask for the detail before you commit.
Yes — and look at how they’re written, not just the star rating. Reviews from real local addresses that describe specific jobs (‘re-roofed our semi in Roffey’) are far more telling than generic five-star praise, and a sudden burst of new reviews can be a warning sign. Ask for references or examples of work in your area and, ideally, of your property type. A verifiable track record in Horsham — work you can see, customers who’ll vouch for it — is the single best predictor of how your job will actually go. Our best contractors guide explains what to weigh.
At minimum £2 million public liability insurance, and ideally £5 million — roofing involves work at height, scaffold and heavy materials over your property and, potentially, the public, so proper cover matters. Always ask to see the certificate before work starts; a legitimate contractor provides it without hesitation, and one who won’t or can’t is telling you something. Check the cover is current and in the trading name you’re contracting with. It protects you if something goes wrong — damage to your property or injury on site shouldn’t become your liability because the roofer wasn’t insured.
Be wary of any roofer who will only take cash or pushes for a large cash deposit. Legitimate firms invoice properly and accept traceable payment, which protects both sides and gives you a record for any guarantee claim. Cash-only demands are a common red flag — they can indicate a firm operating outside normal accountability, and they leave you with no paper trail if the work is poor or the guarantee is needed. A modest deposit against a written quote, paid traceably, with the balance on completion, is the normal and safe arrangement.
No call-out fees. No obligation. Just an honest quote from a local Horsham roofer who turns up when they say they will.
