Do I need planning permission for a new roof in Kent?

Generally, replacing your roof with like‑for‑like materials doesn’t require planning permission. However, if you’re changing the material or altering the roof shape significantly, you might need permission. It’s always worth a quick check with your local Kent council’s planning team, and your roofer should be able to advise on whether building regulations approval is needed for the structural work. For definitive guidance, always check with your local Kent council's planning team or Local Authority Building Control (LABC).

How much should I expect to pay for a roofer in Kent?

Costs vary widely depending on the job, materials, and your property’s specifics. A simple tile repair might be approximately £300–£800, while a full flat roof replacement on an extension could be roughly £1,200–£2,500. For a full pitched roof re‑cover on a typical family home, think in the region of £4,000–£7,000, but premium materials will push that higher. The key is to get at least three detailed, written quotes so you can compare what’s actually being offered.

What’s the difference between a roofer and a general builder?

A roofer specialises exclusively in roofs – repairs, replacements, new installations, and related work like flashing and guttering. A general builder might tackle a roof as part of a larger project, but they don’t usually have the day‑to‑day experience with different roofing systems, materials, and Kent‑specific quirks that a dedicated roofer brings. For anything beyond a minor patch, a specialist roofer is usually the safer bet for quality and longevity.

Can I use a roofer who isn’t registered with NFRC or TrustMark?

You can legally hire anyone to do roofing work, but registration with a recognised body like the National Federation of Roofing Contractors (NFRC) or TrustMark is a strong indicator that they’ve been assessed for competence, insurance, and adherence to trade standards. It’s not a guarantee, but it does give you an extra layer of reassurance – especially for larger or more complex jobs. If a roofer isn’t registered, ask them why and look closely at their references and insurance proof.

What if my roofer goes out of business after doing a bad job?

This is why guarantees and insurance matter. If the roofer was a member of a trade association, you may be able to pursue a complaint through their scheme. If you paid by credit card, you might have Section 75 consumer protection for costs between £100 and £30,000. For debit cards or bank transfers, you’d rely on the roofer’s own guarantees or potentially a small claims court claim. Citizens Advice can offer further guidance on your rights. That uncertainty is exactly why we stress checking credentials and getting written warranties upfront – it’s far easier to prevent a problem than to chase a solution after the fact.

Reliable vs. Rogue Roofers: Kent's Checklist

Hiring a roofer gets much easier once you stop treating every quote as equally credible. In Kent, the real checks are whether the roofer understands the kind of roof you have, whether the quote is properly broken down, and whether the business can prove insurance, track record and basic professionalism before any scaffold goes up.

Why Hiring a Reliable Roofer in Kent Matters

A reliable roofer protects your home from Kent’s notoriously changeable weather and preserves the value of your property.

Living in Kent means dealing with everything from driving rain off the Thames Estuary to salty coastal winds in places like Folkestone and Whitstable. Our housing stock is just as varied – Victorian terraces in Maidstone, post‑war semis in Tunbridge Wells, period cottages in Sevenoaks, and newer builds near the Medway towns. A roofer who understands how these different properties behave – how older lead flashing reacts to damp, or how modern flat roofs need proper drainage – is essential. Get it wrong and you’re not just looking at a leak; you risk structural damage, mould, and far higher repair bills down the line. For further guidance on maintaining your roof, the National Federation of Roofing Contractors (NFRC) offers homeowner advice.

One common problem is using a contractor who does not understand the roof type in front of them. On older properties, the wrong materials or details can create new moisture problems instead of solving the original leak.

Step 1: Know What You Need (Before You Call)

Before you pick up the phone, get clear on what work you actually need.

📺 Watch: The Five Most–Common Causes of Roof Leaks – And What You Can Do — Retex Roofing & Exteriors

Start by having a good look at your roof from the ground (or use binoculars). Note any obvious issues: missing or slipped tiles, sagging sections, moss growth, damp patches on the ceiling, or flashing that looks cracked or lifted. Think about the scope – is it a small repair, a section replacement, or are you considering a full roof renewal because the covering is nearing the end of its life?

Having a rough idea helps roofers give you accurate quotes and stops you from getting vague estimates that could balloon later.

Common jobs: tile or slate replacement, flat roof repair (felt, fibreglass, lead), gutter and flashing work, chimney repairs, moss treatment, full roof strip and re‑cover.
Age clues: If your roof is over 20‑25 years old and showing wear, a full replacement might be more sensible than repeated patches.
Access: Note if scaffolding will be needed due to height or nearby obstacles – this affects cost and timing. For more general home maintenance tips, check out our KentHub Blog.

A vague request like “fix the leak” often produces wildly different interpretations. A quick visual check and a clear description save time and make the quotes easier to compare properly.

Step 2: Finding Reputable Roofers in Kent

The best way to find a trustworthy roofer combines personal recommendations with vetted trade directories.

Start with people you know – neighbours, friends, or local community Facebook groups for your town or village. A recommendation from someone who’s had similar work done on a comparable Kent property is gold. Ask about punctuality, communication, and whether the site was left tidy.

Next, look at trusted trade directories that verify credentials. Schemes like the National Federation of Roofing Contractors (NFRC) or TrustMark list members who have been assessed for competence and insurance. These platforms let you search by location and trade, giving you a shortlist of roofers who’ve already passed basic checks. Avoid relying solely on Google ads or cold‑calling leaflets that pop up after a storm. While some legitimate traders advertise this way, it’s also a favoured tactic of cowboys looking to exploit urgent situations.

A good personal recommendation can save time, but it still needs backing up with the usual checks on insurance, paperwork and recent work.

Once you have a shortlist, it’s time to get those quotes. Use our guide to help you find a Kent roofer you can trust: Find a Kent Roofer.

Step 3: The Vetting Process: Questions to Ask & Checks to Make

A reliable roofer will welcome your questions and be able to back up their claims with proof.

Treat the initial conversation like an interview – you’re checking they’re the right fit for your home and your peace of mind. Here’s what to ask, and why it matters:

Experience and specialism: “How long have you been trading as a roofer in Kent?” and “Do you have particular experience with slate, tile, flat roofs, or heritage properties?” A roofer who’s worked on similar Kent homes will know the local quirks – like how older timber frames need ventilation or why certain tiles suit the Wealden climate.
Credentials and insurance: “Are you a member of the National Federation of Roofing Contractors (NFRC) or TrustMark?” and “Can you show me your public liability insurance certificate?” Membership in a recognised scheme means they’ve been assessed against industry standards. Insurance is non‑negotiable – if something goes wrong or a passerby is injured, you need to know they’re covered.
Guarantees: “What warranty do you offer on materials and workmanship?” A confident roofer will back their work – typical guarantees range from 10 years on materials to 2 years on labour, but get it in writing.
References and local work: “Can you provide references from recent jobs in Kent, or show me photos of similar roofs you’ve worked on?” Speaking to past clients or seeing work on a nearby property gives you real‑world insight.
Detailed quote: “Will you provide a written, itemised quote?” This should break down labour, materials (including type and quantity), scaffolding, waste removal, and VAT. Vague verbal estimates are a red flag.
Kent‑specific knowledge: “Are you familiar with Kent’s building regulations for roofing work?” and “Do you understand the particular challenges of properties in [your area]?” Linking to official guidance shows they take compliance seriously – you can find official guidance on GOV.UK.

Always ask to see the roofer’s public liability insurance certificate and check the expiry date. A reputable tradesperson should have it ready to show you.

Understanding Roofing Quotes & Costs in Kent

Roofing quotes in Kent vary based on materials, roof size, complexity, access, and the type of work needed.

It’s normal to see a range of prices for seemingly similar jobs. That can reflect differences in the quality of materials, whether the roofer includes stripping old coverings, and how much scaffolding is required for safe access. A quote that seems unusually low often cuts corners somewhere.

What should a quote include? Look for:

Clear description of the work (e.g., “replace damaged concrete tiles on south slope, match existing”)
Itemised materials (type, brand, quantity)
Labour costs and estimated timeline
Scaffolding hire and erection/dismantling
Waste removal (skip or muckaway)
VAT at the current rate
Any guarantees on materials and workmanship

Getting three detailed, written quotes lets you compare apples to apples and see what is actually included rather than reacting to the headline figure.

Now you know what fair value looks like – Find a Kent Roofer and get a couple of quotes from vetted local tradespeople.

Spotting “Cowboy” Roofers in Kent

Cowboy roofers use predictable tactics – knowing them helps you say no before they get a foot in the door.

High‑pressure sales are a classic warning sign. If a trader turns up unannounced, claims they were “just in the area” and spotted urgent damage, and pushes you to sign there and then, treat it with suspicion. Legitimate roofers rarely cold‑call; they rely on reputation and recommendations.

Other red flags include:

Vague or verbal‑only quotes that lack detail on materials or labour
Demanding a large upfront payment (more than 20‑30%) before any materials arrive
Unable or unwilling to show proof of insurance or trade body membership
Poor communication – missed calls, vague answers, or refusing to put anything in writing
Claiming your problem is far worse than it is because of “local Kent conditions” to justify inflated costs
Offering to start work today with a “special cash‑only discount”

This kind of scare tactic is exactly why a second opinion is worth getting when the recommended work suddenly jumps from a small repair to a full replacement.

If something feels off, trust your gut. It’s always better to wait for a second quote than to rush into a job you might regret. For advice on dealing with rogue traders, Citizens Advice offers excellent guidance.

Step 4: The Contract & The Work

A clear contract and proper checks at the end protect you from misunderstandings and ensure the job is done right.

Once you’ve chosen a roofer, get a written agreement before any materials arrive or scaffolding goes up. This doesn’t need to be a legal epic – a simple document outlining the scope, price, payment schedule, start and end dates, and what’s included (and excluded) is enough. It sets expectations and gives you something to refer to if questions arise later.

During the work, agree on how you’ll be contacted for updates – a quick text or call at the end of each day is reasonable. Discuss access arrangements, where materials will be stored, and how they’ll protect your garden or driveway.

When the roofer says they’re finished, don’t just take their word for it. Do a thorough walk‑around:

Check the finish – are tiles or slates evenly laid, with no obvious gaps or lifting?
Look at flashing around chimneys, valleys, and roof‑to‑wall junctions – it should be neat and sealed.
Ensure gutters and downspouts are clear of debris and properly attached.
Confirm the site is clean – no stray nails, old materials, or rubbish left behind.
For older Kent properties, pay special attention to lead flashing and timber soffits – these areas are prone to damage if not handled with care.

Make a snagging list of any minor issues like a loose tile or a bit of cement smear and agree on a timescale for the roofer to put them right. A professional should address these promptly because they were part of the original agreement. If you have further questions, don’t hesitate to Get in Touch with KentHub.
