Can a single ridge tile be replaced?

What replacing one tile involves

The process is simple in outline. A roofer reaches the ridge safely, usually from a ladder and roof ladder or a scaffold platform, and examines the broken tile and the ones on either side. The damaged tile is eased out, and any mortar still stuck to the seat is chipped away so that the new tile sits on clean ground.

The replacement is then set. On a mortar ridge, it goes down on a fresh bed, pressed level with its neighbours, and the joints are struck off. On a dry-fix ridge, the tile is clipped or fixed to the ridge batten and the system's fittings, with no wet bed at all. Either way, a mechanical fixing holds it, since BS 5534:2014 expects tiles at the ridge to be fixed that way rather than left on mortar alone.

Before leaving, the roofer checks the line of the ridge from the ground. It should run level, with even joints and no tile rocking under a gloved hand.

Matching the tile

Ridge tiles come in several shapes. The half-round is a plain curved section, the angled or Y-shaped version has a sharper profile, and hogback or decorative types have a raised crest. Each is made in clay or concrete and in many colours and sizes. A replacement that looks close from the pavement can look wrong from the first-floor window opposite.

Colour is the harder part. A tile that has weathered for years has faded, mossed or darkened, and a brand-new one sits out like a sore thumb. On an older roof we hunt first for a reclaimed tile in the same shape and a similar age, which blends in at once. If we need a new one, we choose the nearest colour and size and tell you it will weather in over a season or two.

The ridge must also suit what sits below. A clay plain-tile roof keeps a clay ridge. A stone slate roof usually calls for a stone ridge or a close match. Swapping the ridge material for a visibly different one can need consent where the house is listed, so ask B&NES planning before you order anything.

Is it really only one tile

Many callers describe one broken tile and are right. Sometimes the one you can see is the symptom. A tile that cracked because the bedding around it had failed will leave its neighbours loose, and the repair then needs a longer stretch of ridge relaid.

Here is how we judge it on the day.

• Tap and wobble test. Tiles on either side are pressed gently by hand. Ones that rock or sound hollow are not held.
• Look at the joints. Open, crumbling or hairline-cracked mortar across several tiles suggests the bed is tired along the whole run.
• Check the cause. Damage from a dropped branch is a one-off. Damage from movement in the ridge is likely to be repeated.
• Look at the ends. The tiles at the verge take the most wind and are often the first to loosen.

If the surrounding ridge is sound, the single tile is the whole job. If it is not, you will be told, with photographs, and the choice between patching and relaying is yours. Our guidance on how long a bedded ridge lasts is in the answer on when to rebed a ridge.

Timing and weather

Mortar needs mild, dry conditions to set properly. Laid in hard frost or steady rain, it can fail before it has gained any strength. For that reason a single-tile repair is often easy in spring or summer and fiddly in January. If a tile has fallen in winter and water is entering, we make the area safe or cover the gap first and complete the fix when conditions allow. What can be done in a cold spell, and what is better left, is set out in our winter ridge guide.

A dry-fix replacement is less sensitive to the weather, because it has no wet mortar to protect, though the roofer still has to work safely in wind and wet.

If a tile has come down in a storm, photographs of the damage and the broken tile on the ground are helpful. Pick up fragments only if it is safe to do so.

What it costs and what drives the price

For a tile or two, the largest part of the cost is usually reaching the ridge safely rather than the tile itself. A tall house that needs a tower scaffold costs more to work on than a bungalow reached by a roof ladder. The nearness of neighbouring buildings, the slope and the number of tiles to replace also matter.

There is no sourced typical price for a single ridge tile or a mortar repair, so none is printed here. MyBuilder's 2026 guide gives £40 to £60 per linear metre for a full dry ridge, which shows how a longer stretch is measured. A fixed price for your roof follows the survey.

A small repair can also be the right moment to look at related parts. The hips, which run down the roof's corners, depend on a bracket at the foot to stop them sliding, as the page on the hip iron describes. And if the gable ends are noisy, see dry verge problems. Our ridge and verge repairs hub covers the full list of jobs along the top of a roof.

We repair where repair works, so a one-tile job stays a one-tile job when the roof allows it.
