Loose ridge tiles? When to repoint, rebed or fit a dry ridge
Quick answer
Repointing can make sense if only the exposed mortar has worn away and the ridge tiles and bedding are still sound. If a ridge tile has shifted or the mortar beneath it has failed, the roofer needs to check how the tile is supported and secured. Where several tiles are affected or repairs keep failing, ask whether a compatible dry ridge system would suit the roof.
Repointing, rebedding and dry ridge compared
The ridge is the line at the top where the two slopes of a pitched roof meet. On a mortar-bedded ridge, the visible pointing finishes the joint at the edge. The bedding underneath supports the tile. Knowing which part has failed helps explain why two roofers might recommend different repairs.
Option | When it makes sense |
|---|---|
Repointing | The exposed mortar has worn away in places, while the tiles and bedding are sound. |
Rebedding and securing | The bedding has failed in an isolated section. The roofer checks whether the tiles can be reused and how they will be secured. |
Dry ridge | Several tiles or sections need work, or a compatible mechanically fixed system suits the roof and the scope of the repair. |
What should a roofer check on a loose ridge?
From ground level you may see a tile sitting out of line, missing mortar, or fragments in the gutter or on the ground. A closer inspection should establish whether the wear is limited to the visible joint, whether the tile or bedding has moved, and whether the problem affects one tile or several. Ask the roofer to check the surrounding roof covering and any existing fixings as well.
If a ridge tile is visibly displaced or looks as though it could fall, keep clear of the area below and get urgent advice. Leave the close inspection to a roofer.
For a planned inspection, see our roof repair service. If material has already fallen or looks unstable after high winds, contact us about emergency roof repairs.
When is repointing enough?
Repointing renews the exposed mortar at the joint. It can be a sensible local repair where the tile is secure and the bed beneath it is still sound. Ask the roofer how they checked that before agreeing to the work. If a tile has lifted or rocked because the bed has broken down, renewing the surface joint leaves the underlying fault unresolved.
When does a ridge tile need rebedding?
Rebedding means lifting the affected tile and renewing the mortar bed it sits on. A roofer may recommend this for a short section where the neighbouring ridge is still sound and a compatible repair is possible. Ask how the tile will be mechanically secured as part of the proposed work and whether any cracked or damaged tiles need replacing.
When is a dry ridge system worth considering?
A dry ridge system secures the ridge tiles with mechanical fixings and uses purpose-made components to weather the joint. It’s worth discussing if the mortar is failing along several sections or you’ve had repeated problems. The roofer should confirm that the system suits the roof covering, ridge tile profile and roof pitch, and explain how ventilation is handled.

What should a ridge repair quote cover?
The extent of the work. Ask which tiles or sections need attention and why.
The proposed repair. Check whether the quote covers repointing, lifting and securing tiles, or a dry ridge system.
Materials and access. Ask which tiles can be reused, how the work will be accessed and whether clearing away the old materials is included.
If one quote covers a local repair and the other covers a whole ridge, ask what the roofer found along the rest of the run. Our roof repair quote checklist gives you a way to compare both scopes.
Ridge tile repair FAQs
Do cracks in ridge mortar mean the tiles are loose?
Cracks can be limited to the exposed pointing or can indicate that the bedding underneath has failed. A roofer needs to check whether the tiles are still secure before recommending a repair.
Can the existing ridge tiles be reused?
Often, if the tiles are sound and suit the proposed fixing method. The roofer should check for cracks and confirm that any tiles used with a dry ridge system are compatible.
Does one loose ridge tile mean the whole ridge needs replacing?
An isolated fault may be repairable if the neighbouring tiles and their support are sound. If several tiles have moved or there’s deterioration along the run, ask the roofer to explain the options for a wider repair.
