Roof tile bedding mortar supports ridge caps from underneath. Flexible pointing seals the exposed edges and joints while allowing for normal roof movement. They do different jobs: **fresh pointing cannot rebuild crumbling bedding beneath a loose cap**. If the bed has failed, the affected caps need lifting and rebedding before pointing.

At R&R Restorations, we rebed caps where the bedding has failed, then apply flexible pointing. The first question is whether the mortar underneath is sound, not which colour pointing to use.

## In summary

- Bedding mortar forms the supporting bed; flexible pointing finishes the exposed edges and joints.
- Failed pointing over sound bedding may need repointing only. Failed bedding needs rebedding as well.
- A roof bedding mix and a tub of flexible pointing are not interchangeable unless the product is expressly designed for both jobs.
- Have the condition checked before accepting a surface-only repair. Ground-level photos can start an enquiry, but cannot prove the hidden bedding is sound.

## What is the difference between bedding mortar and flexible pointing?

Bedding mortar is the sand-and-cement material beneath the caps on a mortar-bedded tiled roof. Flexible pointing is a purpose-made compound applied to the exposed bedding faces and cap joints; it keeps some flexibility after curing rather than setting like ordinary cement mortar.

Ridge caps are the shaped tiles covering the roof's peaks and sloping outside corners, called hips. This guide concerns concrete and terracotta capping, not the folded metal ridge capping on a Colorbond roof.

| Material or repair | Where it belongs | What it does | What it cannot do |
| --- | --- | --- | --- |
| Bedding mortar | Beneath ridge and hip caps | Supports and positions the caps | Replace the roof's required fixing system or flexible finish |
| Flexible pointing | Along the exposed bedding faces and cap joints | Seals joints and accommodates normal movement; suitable tested products also act as adhesive mechanical fasteners | Rebuild a missing or crumbling mortar bed |
| Rebedding | Where the supporting bed has failed | Removes failed bedding and resets caps on fresh mortar | Repair a cracked cap without replacing it |
| Repointing | Where the outer pointing needs renewing | Prepares the surface and replaces the failed outer material | Fix unrelated leaks elsewhere on the roof |

Flexible pointing is more than a coloured cosmetic strip. [Monier describes its flexible pointing](https://www.monier.com.au/roof-tiles/accessories/) as an adhesive mechanical fastener for concrete and terracotta hip and ridge tiles. Its flexibility helps it move with the roof without cracking or breaking away. That is a property of the specified product and installation, not a promise that any mortar with an additive will do the same job.

Our ridge repair method uses flexible pointing after any necessary rebedding. We don't treat the materials as competing choices for the same layer.

## What mortar mix is used for roof tile bedding?

Roof tile bedding uses a mortar formulated for roof tiling, commonly based on sand and cement. The right mix depends on the specified bedding product and roof system; a bag labelled “mortar” does not, by itself, confirm suitability.

For a manufacturer example, [Monier's rebedding demonstration](https://www.youtube.com/watch?v=ZnDyR9qsgKU), published on 14 December 2016, describes its premixed bedding mortar as **four parts sand to one part cement**, with additives for workability. That explains the familiar **4:1 sand-to-cement ratio**. It is not an instruction to change the proportions of a packaged product or to copy an old recipe onto every roof.

The labels matter:

- Cement is an ingredient, not the complete bedding mix.
- A premixed dry bedding mortar has ingredients already proportioned and needs preparation according to its instructions.
- A ready-to-use flexible pointing compound is a different product, with its own rules for mixing, application and curing.
- An all-in-one bedding-and-pointing product must be assessed against its own stated uses. Don't assume every flexible pointing compound can also be used as a deep bedding layer.

A bonding additive is not a shortcut to making an unspecified mix into a tested flexible pointing system. For a repair with us, the useful distinction is whether your roof needs the bedding replaced, the pointing renewed, or both. Ask which materials are proposed for your roof once the condition is known.

Monier's product page and demonstration were checked on 28 October 2026. Manufacturer examples here explain the materials, not the brands used on an R&R job.

## When do ridge caps need rebedding rather than repointing?

Ridge caps need rebedding when the mortar underneath no longer provides a sound bed. If the bed remains sound and only the outer pointing has failed, repointing may be enough.

Loose or displaced caps, substantial missing bedding and mortar that crumbles during a professional assessment point towards work beneath the surface. A visible crack in the outer pointing alone does not establish that every cap needs lifting.

From the ground, you may notice a cap out of line, missing sections beside the capping or fallen mortar fragments. Tell us where you've seen the problem and whether there is a leak. Leave any lifting, rocking or scraping tests to the person assessing the roof: climbing up to check can cause a fall or break tiles.

We rebed where the bedding has failed. That can mean repairing affected sections rather than lifting every cap across the roof. Ask for the proposed rebedding areas to be identified in the quote, so “repointing” isn't mistaken for rebuilding all the mortar underneath.

A cracked cap is a separate fault. Sound bedding and fresh pointing won't make a broken tile intact; our [guide to fixing broken roof tiles](/blog/fixing-roof-tiles) explains replacement and matching.

## Why doesn't pointing over failed bedding last?

New pointing needs a sound surface and properly supported caps. When the bed is crumbling or the cap can move independently, the new outer layer is left bridging a fault it was not designed to repair.

The pointing may look tidy at handover while the weak material remains hidden. It can then pull away with loose mortar or separate where the cap moves. Flexibility accommodates normal roof movement; it does not remove the need for a sound bed.

Think of a ridge with a neat new edge but a void underneath the cap. Adding more material to the visible face doesn't fill and rebuild that supporting bed in the way lifting and resetting the cap does. The cause remains, even if the crack disappears from view.

This is why our published sequence is rebedding where needed, followed by flexible pointing. Roof painting is later surface work, not a substitute for either repair.

Our customer Julie described the ridge work in her Google review dated **20 October 2026**, published on our website:

> “They did a phenomenal job bringing our tired roof back to life, including fully cleaning it and completely repointing the ridge caps.”

That is a customer's account of completed work, not evidence that your roof needs the same scope. Your bedding condition still decides the repair.

## What needs checking before flexible pointing goes on?

Before flexible pointing is applied, the bedding, contact surfaces and drainage details need to suit the chosen product. Product preparation and curing instructions matter as much as the appearance of the finished line.

Before accepting a roof pointing repair, ask:

| Ask about | What you need explained |
| --- | --- |
| Failed bedding | Which caps need lifting and resetting before pointing? |
| Surface preparation | What loose material and contamination must be removed so the compound can bond? |
| Product choice | Is it a roof-pointing compound suited to these tiles and the required fixing arrangement? |
| Weather and curing | When can it be applied, and what conditions must it be protected from? |
| Drainage | Which openings are deliberate weep holes rather than damage? |

For example, [Selleys' Point Works instructions](https://www.selleys.com.au/products/glues-adhesives/construction-adhesives/point-works/), checked on 28 October 2026, require contact with the roof tiles and beneath the cap edges. They also require weep holes through the pointing and bedding, and say never to add water to restore the compound's trowelling ability.

Those details show why a generic “add water and smooth it over” approach is unreliable. Use the instructions for the actual product. We agree the repair scope and timing before work starts; the quote sets out the areas, preparation and repairs included.

Our published October 2026 guide puts repointing at **$25 to $30 per lineal metre**, but that is not an automatic rate for lifting and rebedding failed caps. See our [roof repointing cost guide](/blog/roof-repointing-cost) for the budget ranges and what changes the price. Compare the work included, not just the metre rate.

## Is R&R Restorations right for your ridge repair?

We're a good fit if you have a concrete or terracotta tiled roof needing ridge repointing, rebedding or related repairs across the Gold Coast, Brisbane and Logan, Tweed Heads or the Northern Rivers. We're owner-operated by Alex Rowe, and our assessment and itemised quote separate the work needed from a cosmetic finish.

You can ask about a failed ridge joint without committing to a full roof restoration. We carry out focused repairs as well as broader roof restoration work.

Ridge pointing is not the right answer if the leak comes from a flashing, a broken tile away from the ridge or a metal-roof fixing. Our [roof repairs service](/services/roof-repairs-gold-coast) looks for the cause rather than assuming the ridge is responsible. If the structure beneath the roof is unsound, a new pointing line won't solve that either.

## Frequently asked questions

### Can old ridge caps be reused when rebedding?

Sound caps may be reset on fresh bedding. Cracked or otherwise unsuitable caps need replacement. The assessment should distinguish failed mortar from failed tiles rather than assuming both need replacing.

### Is roof tile bedding mortar waterproof?

Don't treat bedding mortar as a standalone waterproofing system. Keeping rain out depends on the tiles, capping, pointing, joints and drainage working together. Smearing more mortar over a joint is not a reliable diagnosis or repair.

### Can I repair roof pointing myself?

We recommend leaving roof access and ridge repairs to a roofing professional. The work involves fall risks, fragile tiles and judging the condition beneath the pointing. Photos taken safely from the ground are enough to begin an enquiry with us.

### Should small holes in the pointing be sealed?

Not without identifying them. Weep holes are deliberate drainage openings, while random cracks and missing material are faults. Blocking the intended drainage can trap water. Ask the roofer to explain any openings you're concerned about.

### Does flexible pointing work on terracotta ridge caps?

Suitable flexible pointing products are made for both concrete and terracotta capping. The product, surface condition and preparation still matter. We assess both tile types for rebedding and repointing.

### Does new pointing mean the roof also needs painting?

No. If the ridge joints are the problem and the rest of the roof is sound, repointing can be a separate job. We discuss roof restoration when the roof needs broader work, not simply because a ridge joint needs repair.

## How do you find out which repair your roof needs?

Send your suburb, roof type and what you've noticed through our [ridge capping repair enquiry](/services/repointing-gold-coast#quote). Include photos taken safely from the ground if you have them. We'll assess whether the bedding needs replacing, the pointing needs renewing or a different fault needs fixing, then set out the work in an itemised quote.
