📞 Call Now: 0140 358 1272Most Horsham repair calls fall into a few predictable patterns tied to the housing stock. The post-war concrete-tile estates — Roffey, Littlehaven, Holbrook — generate slipped-tile and nail-sickness calls. Victorian and Edwardian terraces near the town centre generate slate slippage and lead flashing failure. The cost of any repair comes down to access (can we reach it from a ladder or does it need scaffold), the material needed to match, and how much of the surrounding area has also failed.
| Work | Typical Cost | Notes |
|---|---|---|
| Replace slipped/broken tiles (up to 10) | £150–£400 | Single visit; matched tile |
| Lead flashing repair (chimney/abutment) | £250–£600 | Correctly dressed into masonry |
| Ridge repointing | £400–£900 | Full ridge; era-correct mortar |
| Valley relining | £500–£1,200 | Lead or GRP |
| Slate re-fixing / tingle repair | £200–£500 | Victorian terrace stock |
| Nail-sickness re-fixing (partial) | £400–£1,000 | Below the 40% re-roof threshold |
Prices include labour, materials, access and VAT. We do not charge a call-out fee. If scaffold is required for a high or awkward repair, it is quoted transparently up front.
On the concrete-tile estates around Horsham, the key question is how far nail sickness has spread. Below roughly 40% of tiles affected, targeted re-fixing is good value. Above that, the cost of systematically re-fixing every tile approaches a full re-roof — and the remaining original tiles will keep failing anyway. We give an honest count during the survey rather than defaulting to the bigger job.
Where more than around 40% of fixings have failed, systematic re-nailing costs approach a full re-roof, making replacement the better value option. — NFRC technical guidance
Slipped tiles are the most common call, usually the first visible sign of nail sickness on the concrete-tile estates. Failed lead flashing around chimneys and abutments is the second — old mortar-based fillets crack and let water track behind the covering. Blocked or split valleys are common on properties backing onto the tree canopy near St Leonard’s Forest, where leaf litter accumulates and holds water until the liner fails. Ridge movement shows up on older mortar-bedded ridges after enough freeze-thaw cycles have cracked the bedding. Each of these has a clear repair; the skill is diagnosing which one is actually causing the leak, because water rarely enters where it appears inside.
A repair quote from us specifies the exact fault, the material used to fix it, whether scaffold or ladder access is needed, and a fixed price — not a vague estimate that grows once work starts. We photograph the fault from roof level so you can see what you’re paying for. Where we find a second issue while we’re up there — a common outcome, since roof faults cluster — we quote it separately rather than adding it to the bill without asking. That honesty is why most of our Horsham work comes from repeat customers and recommendations.
Roof repair demand in Horsham follows the weather. Autumn brings valley and gutter blockages as leaves come down from the tree canopy around St Leonard’s Forest and the mature roads across the town. Winter’s freeze-thaw cycles crack ridge mortar and open up hairline faults, and the first heavy winter storms expose slipped tiles and lifted flashings. Spring is when the damage done over winter shows up as internal staining. The practical lesson is that a small fault found in early autumn is far cheaper to fix than the same fault left to work through a winter of West Sussex rain. If you can see anything amiss from the ground — a displaced tile, a sagging gutter, moss building on a valley — it is worth a look before the wet season.
Storm damage is a special case. If a repair follows a storm, the cause and the damage need documenting for any insurance claim — insurers pay for sudden storm damage but not for gradual wear the storm merely exposed. We provide written reports that separate the two clearly, which speeds up settlement. For active leaks we attend within 2–4 hours to make the roof safe, then quote the permanent repair once the emergency is contained. Emergency attendance carries no call-out fee — you pay for the make-safe materials and labour, and the permanent repair is quoted separately and transparently.
Every quote follows a free survey with no call-out fee. We attend survey requests within 3–5 working days and reach emergencies within 2–4 hours. You receive a written, itemised, fixed-price quote before any work starts — no verbal estimates and no bills that exceed the accepted quote. We are NFRC registered and carry £5 million public liability insurance, and all work carries a written 10-year workmanship guarantee. We cover Horsham, Southwater, Billingshurst, Pulborough, Storrington, Henfield and the Horsham neighbourhoods of Roffey, Broadbridge Heath, Littlehaven, North Heath, Holbrook and Southgate, with no travel premium. Call 0140 358 1272 to arrange a survey.
"Two slipped tiles on our Littlehaven semi fixed same week, plus they spotted a cracked one we’d missed. £220 all in."
"Lead flashing round the chimney had failed. Repaired properly, dressed into the brickwork, no more damp patch."
"Honest about it only needing a repair, not the re-roof another firm tried to sell us."
Not sure whether to repair or replace? Our honest decision guide walks the 30% rule and cost-per-year arithmetic.
Minor repairs such as replacing slipped tiles or resealing flashing typically cost £150–£400 in Horsham. Mid-range jobs run more: ridge repointing £400–£900, valley relining £500–£1,200, and a lead flashing repair £250–£600. Larger repairs involving structural or extensive lead work cost more again. All quotes are free with no call-out fee, and prices include labour, materials, access and VAT. The main cost drivers are access (ladder versus scaffold), the material needed to match, and how much of the surrounding area has also failed. See our guide to what to do if your roof is leaking.
No. Surveys and quotes are free across Horsham and West Sussex, and you only pay for work you approve in writing. A call-out fee is a common way for some firms to recover the cost of quoting, but we’d rather win the work on the quote itself. For emergencies we still attend within 2–4 hours with no call-out fee — you pay only for the make-safe materials and labour, and the permanent repair is quoted separately. That way there’s never a charge just for us turning up to look.
For non-urgent repairs we typically attend within 3–5 working days. Active leaks and storm damage are prioritised and attended within 2–4 hours to make the roof safe, with the permanent repair to follow. Autumn and winter are busiest — the first gales and freeze-thaw cycles expose faults across the town at once — so a small fault found in early autumn is both cheaper and quicker to fix than the same fault left to work through a winter of West Sussex rain. If you can see something amiss from the ground, it’s worth calling before the wet season.
Repeated tile slippage usually signals nail sickness — the steel nails holding the tiles have corroded over 40–80 years, so tiles slip even though the tiles themselves are sound. It’s extremely common on Horsham’s 1960s–70s concrete-tile estates in Roffey, Littlehaven and Holbrook. Below about 40% of tiles affected, targeted re-fixing is good value; above that, systematic re-nailing approaches the cost of a re-roof and the remaining original nails keep failing anyway. Our guide to nail sickness explains the whole picture and how to tell where your roof stands.
Yes — and this is where roof problems get expensive. Water entering through a failed flashing or slipped tile rarely drips straight down; it tracks along timbers and saturates insulation and ceilings over weeks before it shows inside. A £200 repair left for a season can become a much larger deck, plaster and decoration repair, and in the worst cases rot structural timbers. That’s why we work back from the internal evidence to find the true entry point rather than treating the visible stain. Our guide to finding a roof leak explains why leaks appear where they do.
Yes — and on Horsham’s ageing concrete-tile estates this is the question that matters most. We give a tile-by-tile assessment and an honest count of what has failed. Below roughly 40% nail-sickness failure, a repair is the right call and we’ll say so; above it, a re-roof is genuinely better value and we’ll explain why. We don’t default to the bigger job — most of our work comes from repeat customers and recommendations, which only happens if the advice is straight. See the signs you need a new roof for what tips the balance.
Yes. We re-fix and match slate on the Victorian and Edwardian terraces around the town centre and Denne Road, using tingles — small metal clips — where a nail fixing can’t be remade, and sourcing matching reclaimed slate where tiles are missing. On these roofs it’s usually the nails that fail first while the slate itself is still sound, so careful re-fixing often extends the roof’s life considerably before a full re-slate is needed. Our tile vs slate guide covers how slate roofs age and when matching versus replacing makes sense.
Yes. Repairs in the Causeway, Denne Road and town-centre conservation areas use matching reclaimed materials and lime mortar where required, keeping the work sympathetic to the building and compliant. Genuine like-for-like repair is generally permitted without consent, but we advise on anything that might need approval from Horsham District Council and don’t proceed on controlled work until the position is clear. Getting conservation repairs right protects both the building’s character and you from enforcement. See our conservation area roofing guide for how the rules work.
In most cases, yes. We source reclaimed concrete, clay and Horsham Stone tiles through salvage networks and confirm the match — size, profile, colour and weathering — before ordering, rather than fitting a visible mismatch. Matching matters more than it sounds: a repair patched in obviously different tiles looks worse than the original problem and can affect a sale. On period roofs we’ll identify the exact tile or slate type so the replacement sits correctly. For clay versus concrete specifically, our tile comparison guide explains the differences that affect matching.
It depends on the cause. Sudden, accidental or storm damage is usually covered; gradual wear and tear — like nail sickness or perished flashing — is not, because insurers treat that as maintenance. Where a repair follows a storm, we provide a written report separating genuine storm damage from pre-existing wear, which is what insurers need to accept the claim. If you’re unsure whether your situation qualifies, our guide to whether home insurance covers roof damage walks through what’s typically covered and what isn’t, and how to evidence a claim properly.
You often can’t tell from inside, because water rarely enters where it appears. It penetrates at a failed flashing, slipped tile or blocked valley, then tracks along rafters and battens — sometimes several feet — before dropping onto a ceiling. That’s why we work back from the internal stain and inspect from roof level to find the true entry point, so the repair fixes the cause rather than the symptom. Chasing the visible damp patch is how leaks get ‘repaired’ repeatedly without ever stopping. Our guide to finding a roof leak explains the detective work involved.
Yes — our repairs carry a written workmanship guarantee, with the length depending on the repair, and we confirm it in the quote so you know exactly what’s covered. If a guaranteed repair fails within the covered period, we return free of charge. A guarantee is only as good as the firm behind it, though, so it’s worth choosing a verifiable local roofer who’ll still be around to honour it — which is one reason most of our work comes from repeat custom and recommendation across Horsham rather than one-off jobs.
No call-out fees. No obligation. Just an honest quote from a local Horsham roofer who turns up when they say they will.
