Expert Ridge Tile Re-bedding in Bicester

Ridge tiles sit at the apex of your roof, where two sloping sides meet. Over time, the mortar holding them in place can crack and crumble due to weather and general wear. Re-bedding is the process of carefully removing these loose ridge tiles, cleaning off the old, failing mortar, and then re-fixing them onto a fresh, strong bed of new mortar. It's a vital job to keep your roof secure and watertight.

Several things can cause your ridge tiles to become loose. The main culprit is usually the good old British weather! Constant exposure to rain, wind, and freeze-thaw cycles slowly breaks down the original mortar bed. Movement in the roof structure over many years can also play a part. Sometimes, if the initial job wasn't done with the right mortar mix or care, the ridge tiles may become loose sooner than expected.

You might notice a few tell-tale signs. Look up at your roof ridge: can you see any cracked or crumbling mortar around the ridge tiles? Are any of the tiles visibly out of line, or do they look like they’ve slipped? You might even find bits of old mortar on the ground around your house. If you see any of these, it’s a good time to get a professional opinion, as your ridge tiles likely need attention.

Yes, it can be quite risky. Loose ridge tiles are a weak point on your roof. If one becomes dislodged in high winds, it could fall and damage property or even cause injury. More commonly, gaps in the mortar allow rainwater to seep underneath. This water ingress can lead to damp patches on your ceilings, rot in your roof timbers, and more extensive, costly repairs down the line. It’s much better to sort out loose ridge tiles sooner rather than later.

For ridge tile re-bedding to last a long time, it's crucial to use the right mortar mix. Typically, this involves a specific ratio of good quality sand, cement, and sometimes a plasticiser to improve workability and durability. We make sure the mix is appropriate for the type of tiles and the exposure of your roof. Using the correct mortar ensures a strong bond and helps the re-bedded ridge tiles withstand the weather for many years.

The time it takes to re-bed ridge tiles depends on the length of your roof ridge and how many tiles need attention. For an average semi-detached house, the work can often be completed within a day, provided the weather is cooperative. We'll always give you a clear idea of the timescale when we provide a quotation for the job. We work efficiently to get your roof secure as quickly as possible.

When ridge tiles are re-bedded correctly using quality materials and skilled workmanship, you can expect them to remain secure for many years – often 10 to 20 years or even longer. The exact lifespan will depend on factors like your local weather conditions and the exposure of your roof. Regular checks as part of general roof maintenance can help ensure they stay in top condition for as long as possible.

In most cases, yes, your old ridge tiles can be re-used, as long as they are not cracked or broken. During the re-bedding process, we carefully remove the existing tiles and clean off the old mortar. If the tiles themselves are sound, we'll re-bed them onto the new mortar. If any are damaged, we can usually source matching replacements to ensure your roof still looks its best.

The re-bedding job typically involves a few key steps. First, we’ll safely access your roof ridge. Then, we carefully remove the loose ridge tiles and all the old, deteriorated mortar from both the tiles and the roof structure. We make sure the area is clean and ready for the new mortar. We then lay a fresh bed of specially mixed mortar and securely fix the ridge tiles back in place, pointing them neatly to ensure a weatherproof seal.

Re-pointing ridge tiles generally means applying new mortar to the visible joints where the old mortar has cracked or fallen out, without fully lifting the tiles. Re-bedding, on the other hand, is a more thorough job. It involves completely removing the ridge tiles, cleaning off all the old mortar, and then fixing them back onto a brand new bed of mortar. Re-bedding usually provides a more robust and long-lasting solution, especially if the existing mortar bed has significantly failed.

Absolutely. Loose or poorly bedded ridge tiles are a common cause of roof leaks. When the mortar cracks or gaps appear, rainwater can get underneath the ridge tiles and into your roof space. This can then track down rafters and show up as damp patches or drips on your ceilings. Re-bedding the ridge tiles creates a new, watertight seal at the apex of your roof, which will certainly help to stop this type of leak.

It depends on the condition of the ridge. If only a few specific ridge tiles are loose and the mortar around the others is still sound, it may be possible to just re-bed the affected ones. However, often if one part of the ridge is failing, the rest may not be far behind. For a lasting repair and peace of mind, it’s often best to re-bed the entire length of the ridge. We will assess your roof and advise on the most sensible course of action.
