Slate Roof Repair Market Harborough
Slate covers some of the oldest homes in Market Harborough, from period cottages to Victorian terraces across the Welland Valley. When a slate slips or cracks, rain finds the gap fast, and one loose slate soon becomes a wet ceiling. Tate & Sons Roofing handles slate roof repair in Market Harborough and the wider Harborough District. That runs from a single slipped slate to widespread nail sickness on a heritage roof.
This page walks you through slipped and broken slates, nail sickness, tingle and clip fixes, and matching reclaimed slate. You will also see when a repair beats a full re-slate, and real prices before you call. Slate work sits within the wider service we offer as a roofing contractor across Market Harborough.

Spot the Warning Signs Before One Slate Turns Into a Wet Ceiling
A slate roof usually warns you before it lets water in. Catch it early and a repair does the job, before the loft timber or the ceiling gets involved.
Keep an eye out for these:
- A slate lying in the gutter or on the ground after a windy night
- A dark gap on the roof where a slate has slipped out of line
- Slates that have slid down and now sit unevenly against their neighbours
- Brown water staining on a bedroom ceiling or across loft rafters
- Rusty streaks running down slates, a sign the nails are failing
- Several slates slipping in the same patch within a year
- Daylight showing through the roof when you look up from the loft
One slate off in a gale is often bad luck. A run of them slipping in the same area is different. That pattern points to the nails rotting away, not the slate, and re-fixing one slate will not stop the next going. This is why a proper look comes before any work. Treat the symptom alone and you pay again next winter.
Slipped, Broken or Missing — What Has Actually Gone Wrong Up There
Most slate faults fall into a few clear types, and the fix depends on which one you have. A broken slate is cracked through or has lost a corner, usually from a knock or a foot. That one gets pulled out and replaced. A slipped slate is often sound in itself, but the nails holding it have given way.
Slates hang on two nails near the top edge. On period roofs those nails were often iron, and iron rusts. Once the nail heads corrode through, the slate has nothing left to grip and slides down the pitch. We call this nail sickness, and it is common on the older stock around Great Bowden and Little Bowden.
You cannot re-nail a slipped slate from above without lifting the ones over it. Instead we use a tingle, a thin strip of copper or lead nailed to the batten. The slate slides back into place, then the strip folds up under its bottom edge to hold it. Done in copper or lead, a tingle lasts as long as the slate itself. Our Slate Roofs page covers the wider picture on natural slate.
Repair or Re-Slate? You Get a Straight Answer, Not the Biggest Invoice
A few slipped slates rarely mean the whole roof is finished. A single broken slate, an isolated slip, or one small run is a repair, not a re-slate. The picture changes once the nails have failed across the whole pitch.
The rule of thumb roofers use is straightforward. Once you have replaced roughly a fifth to a quarter of the slates, repairs stop making sense. At that point you are chasing the same fault around the roof, patch after patch. A full strip and re-slate, with fresh nails and battens, becomes the cheaper route over time.
We see this on older cottages around Lubenham and Medbourne. A roof gets three or four slates re-fixed each year, while the real problem is nail sickness across the lot. Michael Tate looks over the whole roof before he calls it either way. You get a clear answer on repair versus re-slate, backed by what he found, not a push toward the bigger bill.
Common Slate Repair Jobs and What They Typically Cost
Different faults call for different work, and the price tracks the job. The table below sets out the repairs we handle most, with real market figures and a plain steer on whether each is a repair or a re-slate.
| :-: | :-: | :-: | :-: |
| Scenario | Likely cause | Typical cost | Repair or re-slate |
| Single slipped slate | One failed nail, wind lift | £150–£250 | Repair with a tingle |
| Several broken slates | Impact, frost, foot traffic | £200–£400 | Repair, slates matched |
| Widespread nail sickness | Iron nails rusted through | £80–£150 per m² | Re-slate the pitch |
| Ridge or valley leak | Cracked mortar, tired lead | £350–£850 | Repair or renew section |
These are general ranges, not a quote for your roof. Access, pitch and how many slates need matching all move the figure. A firm price only comes after a survey.
What Slate Roof Repair Really Costs in Market Harborough
Cost comes down to three things: how many slates, how easy the access, and how hard the slate is to match.
As a guide, a single slipped slate re-fixed with a tingle runs around £150 to £250. A handful of broken slates replaced together lands near £200 to £400. Where nails have failed across a pitch, a re-slate works out at roughly £80 to £150 per square metre. Ridge and lead valley work sits somewhere between £350 and £850, depending on length.
What moves a price up or down:
- **Number of slates*— one slate is a quick visit; a run across the roof is a longer job
- **Access*— a low garage reached by ladder costs less than a two-storey period roof needing scaffold
- **Scaffold*— where it is needed, expect roughly £300 to £600 to put up and take down
- **Slate matching*— reclaimed Welsh slate can run £15 to £30 a slate on heritage work
- **Batten and felt*— perished timber or old felt under the slates adds to a re-slate
Two roofs the same size can price very differently once access and matching come in. The only route to a firm figure is a proper survey, which is exactly what our free survey gives you. You get a clear written price with nothing bolted on afterwards.
Matching Reclaimed Slate on a Heritage Roof
On a period roof, a repair only looks right if the new slate matches the old. Get it wrong and the patch shouts at you from the street. This matters on the listed and older stock around Foxton, Husbands Bosworth and the wider Welland Valley.
Many of the Welsh and British quarries that roofed these homes have closed. New slate rarely matches old slate for colour, thickness and grain. So for heritage work we source reclaimed slate from salvage suppliers, and pick pieces that sit with what is already up there. Where a perfect match is not on, we blend the reclaimed slate in so the repair reads as one roof.
Fixings matter as much as the slate. We use copper or stainless nails and lead tingles, never iron, so the repair outlasts the fault that caused it. For an independent view on caring for an old roof, the SPAB roof maintenance advice is a sound read before you commit to any work.
Ridge, Valley and Lead — Where Slate Roofs Really Let Water In
Plenty of slate roof leaks are not the slates at all. The ridge line, the valleys and the lead flashings take the hardest weather, and they tire first. Cracked ridge mortar lets water track under the slates below it. A split lead valley funnels rain straight into the roof.
Re-bedding a ridge runs around £40 to £60 a metre, so a full ridge on a semi lands near £400 to £800. A tired lead valley renewed on a slate roof sits in the same bracket, more with scaffold. We fix the detail that is actually failing, rather than re-slating around a problem the slates never had. Our Ridge Tile Repairs & Rebedding page goes into ridge work in full.
What Happens When We Come Out to a Slate Repair
A slate repair follows the same order on every visit:
- Michael surveys the roof and finds why the slates are slipping
- Broken or slipped slates are eased out with a slate ripper
- Matching slates, reclaimed where needed, are cut to fit
- Each slate is re-fixed with a copper or lead tingle
- Ridge, valley and flashing detail is checked and made good
- The roof is left sound and the site cleared before we go
Most small slate repairs take a single visit, weather allowing. A re-slate on a full pitch takes longer, and we give you a realistic timeframe before we start. You will know who is turning up and roughly how long the job will run. No optimistic dates just to win the work.
A Look Twice a Year Keeps a Slate Roof Sound for Decades
A slate roof lasts longest when small faults get caught early. Little of this needs a specialist, just a look from the ground now and then.
- Scan the roof after high winds for any slipped or missing slate
- Clear leaves and moss from valleys and gutters each autumn
- Check the loft after heavy rain for damp or fresh staining
- Book a free survey if you spot any warning sign above
Left alone, one slipped slate lets water soak the batten and rafter beneath it. Caught early, the fix is usually one visit and a modest bill. That is the whole case for a quick look now and then.

Got Questions?
Your Slate Roof Repair Questions, Answered Properly
How much does it cost to replace a single slipped slate?
A single slipped slate re-fixed with a tingle usually runs around £150 to £250. The price covers labour, the matching slate and safe access. It rises where scaffold is needed to reach a high or awkward pitch. A handful of slates done together often works out cheaper per slate than one at a time. A firm figure comes after a quick survey.
What is nail sickness and can it be repaired?
Nail sickness is when the nails holding the slates rust through and fail. It is common on period roofs where iron nails were used, often after 70 to 100 years. Where it affects a small patch, we re-fix the slates with copper or lead tingles. Where it has spread across the whole pitch, a re-slate is the lasting fix. Chasing it slate by slate only puts off the bigger job.
What is a tingle and why use one?
A tingle is a thin strip of copper or lead nailed to the batten to hold a slate. You need one because a slipped slate cannot be re-nailed from above without lifting the slates over it. The strip folds up under the bottom edge of the slate to grip it. Done in copper or lead, a tingle lasts as long as the slate. We never use iron, which rusts and fails again.
Can you match the slate on my period roof?
In most cases, yes. Old Welsh and British slate is hard to buy new, so we source reclaimed slate from salvage suppliers. We pick pieces that sit with your existing roof for colour, thickness and grain. Where a perfect match is not on, we blend the reclaimed slate in so the repair reads as one roof. Matching matters most on the older stock around Foxton and Husbands Bosworth.
Should I repair my slate roof or re-slate it?
It depends how much of the roof has failed. A few slipped or broken slates is a repair, plain and simple. Once you have renewed roughly a fifth to a quarter of the slates, repairs stop paying off. At that point nail sickness is likely across the pitch, and a re-slate is cheaper over time. We look over the whole roof before we advise either way.
Why do several slates keep slipping in the same spot?
A run of slips in one area almost always means failing nails. One slate off in a gale is bad luck. Several going in the same patch shows the nails there have rusted through. Re-fixing one slate will not stop the next, because the cause sits under all of them. We fix the run and check whether the rest of that pitch is on the same path.
Do you need scaffold to repair a slate roof?
Not always. A single slate low on a garage or outbuilding can often be reached with a ladder and roof access gear. A two-storey period roof, or a run of slates across a pitch, usually needs scaffold for safe working. Where it is needed, expect roughly £300 to £600 to put up and take down. We tell you before the job whether scaffold is in the price.
My slate roof leaks but the slates look fine — why?
The leak is often the ridge, a valley or the lead flashing, not the slates. These details take the hardest weather and tire first. Cracked ridge mortar or a split lead valley lets water track straight in under sound slates. We find the detail that is actually failing rather than re-slating around it. That way you pay to fix the leak, not the wrong part of the roof.
