Ridge tile repointing in Windsor, Berkshire and South West London: cracked mortar raked out, ridge tiles rebedded and pointed, or the whole ridge converted to a mechanically fixed dry ridge. Book a free roof inspection and you get photos of the ridge and a fixed written quote.
The ridge is the line of tiles along the very top of your roof, and on most older homes in Windsor and Berkshire those tiles sit on a bed of sand and cement. That mortar takes the full force of the weather: sun bakes it, rain soaks it and frost expands the water inside it. After enough winters it cracks, shrinks away from the tiles and starts to wash out.
What to look for from the garden or the street:
Left alone, it gets worse fast. Rain runs in at the highest point of the roof, and a ridge tile that has lost its bed can come off in a gale, which is a heavy piece of clay or concrete falling from the top of the house.
A skim of new mortar over the old cracks is not a repoint. This is the full job.
Loose and failing ridge tiles come off and the old mortar bed is broken out right back to the tile below.
Every tile is cleaned of old mortar so the new bed bonds to it, and any cracked ridge tile is replaced with a match.
Tiles go back on a new mortar bed and are mechanically fixed as well, not held by mortar alone.
The joints between ridge tiles are pointed and finished so water runs off the ridge instead of into it.
Repointing is the right answer on a roof where the look of a traditional mortar ridge matters, such as some period homes in a conservation area. On most other roofs we will offer you the upgrade: a dry ridge system.
A dry ridge fixes every ridge tile with a clip and screw over a ventilated roll, with no mortar at all. There is nothing to crack, nothing to wash out and nothing to repoint in ten years' time. The ventilated roll also lets moist air out of the roof space, which helps keep the timbers in your loft dry.
The current British Standard for slating and tiling, BS 5534, calls for ridge tiles to be mechanically fixed rather than held by mortar alone. A dry ridge does that by design, and it is what we fit as standard on our new roofs. Read more on our dry ridge system page.
Our roof repair cost guide puts ridge tiles rebedded or refixed at £200 to £600 for 2026, mechanically fixed to current standards. The length of the ridge, the number of hips that run down from it and the access you have are what move the figure within that range.
If only two or three tiles have lost their bed, we rebed those and leave the rest, and you get the smaller price. If the mortar has failed along the whole ridge and down the hips, the honest comparison is between a full repoint now and a dry ridge that will not need doing again, and we price both so you can choose.
Ridges that keep failing on a roof that is also leaking elsewhere are a sign of a covering at the end of its life. We will show you the photos and tell you plainly if you are looking at a ridge repair or a new roof.
On this Hampton re-roof every ridge tile was clipped and screwed down rather than bedded in mortar, so there is nothing at the top of the roof left to crack or wash out. Every photo is from the job.
