The short answer
A tingle is a thin band of lead or copper, nailed to a batten and folded up over the lower edge of a slate to hold it where a nail has failed. It is a quick, low-cost way to save a sound slate. How long it holds depends on the strip and on what is behind it. A roof needing many tingles is telling you its nails are failing generally.
What a tingle is and how it is fitted
Slates normally hang from nails through two holes near their heads. When those nails break, the slate loses its hold and starts to slide. A tingle takes over the missing fixing. It is a band of soft metal, a few centimetres wide, with one end nailed to the batten beneath the slate. The name is a trade one, and in some areas you will hear the same thing called a clip or a strap. The free end is bent up and over the tail of the slate, so the slate cannot slip further.
The slate stays where it is, which is the point. That makes a tingle a gentle repair: nothing around it is disturbed, and a roof that has weathered to an even tone keeps its look. There is no need to remove neighbouring slates, and the repair is made from a ladder or roof access system, using a slate ripper, a barbed flat blade that cuts through old nails, worked under the slate to reach the batten. The slate is then pushed back into line and the strip folded over. Because the metal shows as a thin line along the tail of the slate, tingles are visible from the ground if you look, which some owners dislike on a prominent elevation.
Lead or copper strips
Two metals are used. Lead is soft and easy to dress, so it folds neatly over an uneven slate edge and does not crack the slate. It is the traditional choice and tends to weather to a dull grey that sits quietly against the slate. Sheet lead is graded by code, running from Code 3 at 1.32 mm thick to Code 8 at 3.55 mm. Tingle bands are cut from the lighter grades because they carry little load, and we confirm the code on the quote.
Copper is stiffer and springier, which gives a firmer grip on the slate tail but can make it harder to shape neatly. It is often chosen where a longer-lasting metal is wanted, and it turns brown and then green over the years unless the roof is kept clear of acid run-off from moss.
Neither is the right answer everywhere. Which we use on your roof depends on the slate, how much of the strip will show and the other metalwork nearby. Mixing metals that react together is avoided, and the choice is written on the quote.
How long a tingle holds
A tingle has no single lifespan to quote, because the answer turns on the metal, the condition of the slate and the exposure of the slope, and each is described below.
The slate
A tingle only holds a slate that is sound. If the slate is cracked or delaminating, the strip clamps a failing tail and the slate can still break around it.
The batten
The strip is nailed into the batten. If that timber is soft or rotten, the nail pulls out and the tingle goes with it. This is the most common reason a tingle repair comes back.
The metal
Lead is soft and can slowly stretch under the weight of a heavy slate, while copper holds its shape. A band that is correctly fitted to a sound slate and batten can last a long time, but it is a repair to monitor, not one to forget. We suggest a look after the first winter, and again whenever the slope is inspected for gutters or moss.
The wind
On exposed edges, a gust can work at a tingle again and again. Along verges and eaves, a hook or fresh nails are often a better answer than a band.
When many tingles point to a bigger problem
A tingle is a repair for the odd slate. A roof carrying dozens of them is a roof whose nails are failing generally, and each tingle is only dealing with one symptom. Slates around the repaired ones are held by the same ageing fixings, so the next slip is rarely far off.
The pattern we look for is tingles in rows, tingles beside missing slates, and old tingles that have themselves worked loose. That points to nail fatigue across the slope, and the sensible answer is usually to strip and refix the slope. The point at which spot repairs stop paying is a judgement made on the roof, with pictures, in the loft and outside.
Our answer on why slates slip covers the causes tingles do not cure, such as wind lift and rotted battens.
What a tingle costs, and what we recommend
MyBuilder's 2026 slate roof guide gives £60 to £120 as the typical range for a single slate repair across the UK, and £150 to £350 for five to ten slates. A tingle repair sits within that kind of range, but the figure moves with access more than with the metal, as the single slate cost answer explains.
On a survey we photograph the slates in question, check the battens from the loft, and tell you plainly whether tingles will do or whether the slope is past that point. The quote that follows is written, and we give a 10-year workmanship guarantee in writing for the work. Start from our slate roofing page, or ring 01453 933613.
