Honest advice
Is Slate Roofing the Right Fix?
In Lewes, most slate roofing jobs announce themselves before you ever get on the roof. Slate roofs fail differently from tile — the signs are slipping, edge-fretting and nail failure rather than cracked tiles.
Tell-tale signs on a Lewes roof:
Slipped or missing slates, often after wind
Slates delaminating or flaking at the edges (fretting)
Rusty nail heads and slates sliding — nail or peg failure
Cracked or previously face-fixed slates (the wrong repair)
Damp indoors below a slate slope or valley
When it is not the answer: If only a handful of slates have slipped on an otherwise sound roof, single-slate replacement is right — a full re-slate would be premature — see our guide.
Nail sickness — corroded fixings let tiles slip across a whole slope, a common re-roof trigger.
Local Knowledge
Slate Roofing in Lewes: Local Factors
Slate is the signature covering on Lewes's period stock, and matching it properly is what separates a lasting repair from an eyesore. Lewes is a historic county town of listed, timber-framed and tile-hung buildings, with steep narrow twittens making access and material-matching demanding. We source Welsh and reclaimed slate to match gauge, colour and thickness, and detail valleys and verges in lead rather than mortar where the original did.
On Lewes streets like Keere Street, Church Twitten, School Hill, matching the existing slate — gauge, colour and thickness — is non-negotiable, and where the property is listed or in a conservation area we work to what Lewes District Council expects.
Local conditions shape the work here: set in the Ouse valley gap through the Downs, Lewes funnels wind and holds valley damp, and its heritage roofs need traditional care. We factor that into every survey, so the quote reflects your actual roof in Lewes rather than a generic price — and we always tell you honestly if the job is smaller than you feared.
How It Works
How We Handle Slate Roofing in Lewes
Survey & match
We inspect at roof level, identify the slate type and gauge, and confirm matching material — Welsh, Cornish or reclaimed.
Careful strip or repair
Sound slates are salvaged and re-used; failed slates and corroded nails or torching are removed.
Re-slate & detail
New and reclaimed slates are laid to the correct gauge and head-lap, with lead valleys, soakers and verges.
Clean & guarantee
We clear all debris, walk you through the finished roof and issue the written 10-year guarantee.
Every Lewes job runs the same way: a free survey first, then a fixed written quote with no call-out fee and nothing hidden. We turn up when we say we will, keep you posted as the work goes on, protect the areas around the work and clear the site before we leave. You deal with the roofer doing the job, not a call centre — and the price we quote is the price you pay unless we find something and agree it with you first.
In Depth
Slate Roofing in Lewes: What's Involved
Natural slate is a fundamentally different roof to concrete tile. It is thinner, heavier per square metre once laid to the right head-lap, and fixed slate-by-slate with copper or aluminium nails rather than clipped in courses. That is why slate work is slower and more skilled — and why a badly matched or face-fixed repair stands out a mile on a Lewes roof.
The commonest failure we find is not the slate itself but the fixings: the nails corrode (‘nail fatigue’) and slates begin to slip in ones and twos, then in runs. Where the roof is otherwise sound we can strip a slope, salvage the good slate, and re-lay it with new fixings and breathable felt — a far cheaper route than a full re-slate, and one we always check for first.
Detailing is where slate roofs are won or lost. Valleys, hips, abutments and verges should be dressed in lead, not smeared in mortar, and the slate cut and laid to shed water cleanly. We detail the traditional way, which is what keeps a Lewes slate roof watertight for decades rather than years.
The cost-saving move on a slate roof is to act early. A handful of slipped slates left alone lets water into the battens and felt, turning a cheap re-fix into a slope strip — so on a Lewes slate roof, sorting slips promptly is what keeps the bill small.
For a few hundred pounds, an inspection can save you thousands — whether that is spotting a re-roof a seller did not disclose, evidencing that your Lewes roof is sound before you sell, or giving a landlord a paper trail that heads off a dispute later.
Catching failed pointing early is what keeps costs down. Left long enough, water gets past the mortar and into the stack, and a straightforward repoint becomes a rebuild — so on a Lewes stack, dealing with sandy, receding joints promptly is the cheaper path.
The economics are simple: a twice-yearly clear costs little, while the damp that a blocked gutter drives into a Lewes wall can mean re-plastering, redecoration and even masonry repair. Regular clearing is the cheapest insurance a roof has.
Acting on a leaking rooflight early saves money too — a small re-flash now is far cheaper than the ceiling, insulation and plaster damage that a slow rooflight leak causes over a winter in a Lewes loft.
Timescales
How Long Does It Take?
As a guide to what to expect in Lewes, typical job times run:
Job
Typical duration
Single-slate replacement
1–2 hours
Re-fix a slipped area
Half a day
Lead valley in a slate roof
1–2 days
Re-slate one slope
3–5 days
Full re-slate (terraced)
5–8 days
In Lewes, slate work pauses in high wind and driving rain for safe handling, and each day's opening is made watertight before we leave.
Access
Scaffold, Skips & Street Access in Lewes
Access shapes every Lewes quote: slate roofs are usually steeper and need a tower for repairs and full scaffold with edge protection for re-slating. Scaffold is specified for re-slating, valley rebuilds and any work beyond a small repair — always itemised in your written quote, never a hidden extra, and we arrange it.
In Lewes, Lewes is a historic county town of listed, timber-framed and tile-hung buildings, with steep narrow twittens making access and material-matching demanding. Pavement scaffold and skip permits go through Lewes District Council; allow a few working days on streets like Keere Street, Church Twitten, School Hill where space is tight.

Good to know
Living Around the Work in Lewes
Scaffold, a skip and several days of activity on a re-slate; individual slate repairs are quick and quiet. You do not need to stay home for external work — we just need power and access agreed in advance.
We re-slate through most of the year but plan strips around dry, calm windows — slate is heavy and needs safe handling. Locally, set in the Ouse valley gap through the Downs, Lewes funnels wind and holds valley damp, and its heritage roofs need traditional care.
FAQ
Frequently Asked Questions
Yes. We identify the slate type, gauge and thickness and source matching Welsh, Cornish or reclaimed slate. On Lewes's period and conservation stock, matching the original is essential — we never face-fix or mix mismatched slate.
Often just repairs. If most slates are sound and only a few have slipped or the nails have gone locally, we re-fix rather than re-slate. We only recommend a full re-slate when nail fatigue or fretting is widespread — and we tell you honestly after the survey.
Natural slate costs more than concrete tile in both material and labour, because it is heavier, needs steeper detailing and more skilled fixing. But a properly laid slate roof lasts far longer, which is why it is the right choice on Lewes's heritage properties.
Yes. Much of Lewes's slate stock sits in conservation areas or is listed. We use traditional materials and detailing to meet those requirements and can advise on what Lewes District Council will expect.
A well-laid natural slate roof can last 80–100 years or more — far longer than concrete tile. Usually it is the nails and lead detailing that fail first, not the slate, which is why re-fixing and re-leading a sound slate roof is so often the right call in Lewes.
Very often, yes. If the slates are sound and it is the fixings that have failed, we salvage and re-lay the good slate with new nails and felt, topping up with matched reclaimed slate only where needed. It keeps the roof authentic and the cost down.
Yes — a Lewes inspection covers the whole roof, including flat roofs over extensions, garages and dormers, which is often where problems hide. We report on the covering, the upstands and the drainage, and rate each finding by urgency like the rest of the roof.
Yes. We clear around solar panels carefully and reach gutters above conservatories and extensions using the right access, so nothing is skipped or damaged. We will confirm how we will access those runs before we start.
We focus on the rooflight and its weatherproofing, and we can fit manufacturer flashing kits that suit later blind or accessory fitting. If you are planning solar or blinds, tell us at survey and we will allow for it in the install.
