Step One

Ridge capping is a process similar to rebedding and repointing, but it typically involves completely removing the cap to make way for new ones.

Step Two

Once removed, the area is thoroughly cleaned before fresh bedding cement is added, which will hold the ridge cap firmly in place.

Final Result

The final step is to add a flexible pointing mortar over the new bedding cement to prevent water intrusion.

What is Ridge Capping?

Most roofs slope upwards and meet at a peak junction, forming what’s commonly known as a ridge. The ridges of your roof are subjected to weather and mechanical stress, making a compromised ridge a common reason for water ingress.

Ridge capping refers to specially designed tiles used to cover and seal the ridge of your roof. It’s a crucial component of your roof that protects your home against water damage by adding a protective, durable cap over the ridge and a clean and aesthetic finish to your roof.

What are the Different Types of Ridge Capping?

There are two different styles of ridge capping our team specialises in delivering:

Lapped Ridge

The lapped ridge is the most popular and common form of ridge capping on residential homes. It’s a classic with overlapping segments covering the roof ridge, offering a traditional appearance while providing a simple yet effective barrier against the elements.

A-Line Ridge

A more modern alternative, A-Line ridge capping offers a sleeker, more uniform look by offering a continuous, clean line along the roof’s ridge. A-Line Ridge cap tiles sit flush next to each other. An A-Line ridge cap means your roof ridges won’t have the overlapping profile of lapped ridge capping, resulting in a more streamlined look.

A Few Common FAQs

How do I know if my ridge capping needs replacing or repairing?

Indicators for replacement or repair include visible damage or wear, such as cracks or looseness. Signs of water leaks and moisture infiltration in your attic or interior ceilings are also commonly attributed to damaged or dislodged ridge caps. One of the most common telltale signs of a ridge cap that requires attention is cracked pointing, visible outside your home.

Can ridge capping be matched to my existing roof tiles?

Absolutely, we purchase ridge caps from several respected suppliers and can easily match new caps to your existing roof tiles. Many ridge caps are available in various materials and colours, allowing them to blend seamlessly with the existing roof.

How does weather affect ridge capping?

Weather (in particular, extreme conditions like high winds and heavy rainfall) can contribute to dislodging your roof capping. Mechanical stress (such as walking) can also decrease the longevity of your current ridge capping.

An Important Note: Bedding and Pointing

It’s important to note that you can purchase the most expensive ridge caps on the market, but their effectiveness in protecting your home against the elements comes down to having a qualified roofing expert install your caps with industry-standard bedding and pointing.

We can facilitate any ridge cap replacement, which involves removing the old ridge caps and thoroughly cleaning the roofing ridges of old, degraded cement to ensure a clean surface. Our roofers will then install new pre-chosen ridge caps over bedding cement. We’ll then finish the job by adding flexible pointing mortar to the junctions of the caps to prevent rain ingress.

Bedding & Pointing

Our roofers are experts in finishing and sealing your ridge caps with bedding & pointing, an essential service in ensuring a secure and watertight ridge cap. Bedding provides a base for the ridge caps, using mortar to set them in place. Secondly, we add pointing over the cap joins using a flexible, weather-proof mortar to seal the joint and prevent water ingress. Bedding and pointing are crucial for the ridge caps’ longevity and the roof’s overall health.

New Ridge Cap Installation

As part of a reroofing service, new ridge cap installation involves cleaning and preparing the ridge line before applying bedding cement and securing the ridge cap over your tiles. Additional pointing mortar is then used to reinforce waterproofing and prevent water intrusion.

Leaks & Water Damage Repair

Leaks and water damage are common issues that properly installed ridge caps help to prevent; proper installation and maintenance of ridge caps help keep your roof watertight.

Regular inspections, clearing debris, and ensuring proper sealing and alignment are necessary to avoid leaks and water damage. We offer industry-standard leak detection services to detect any weak points within your roof before rebedding and repointing your compromised ridge caps or providing replacement of any damaged ones.

Make An Informed Decision for Your Roof
UV Protection

With high-quality tiles, a fresh new roof offers excellent reflective properties to prevent UV light from penetrating your home, keeping you comfortable and temperate.

Physical Protection

Your tiles are a physical barrier for falling trees, hail, or pests such as rats, possums, and birds from nesting in your attic. An uncompromised roof also protects your insulation.

Pollutant Barrier

Your roof is an essential barrier to the external environment, working in tangent with your ventilation to prevent pollutants and allergens from entering your living space.


With many residential building inspections failing on the roof, a new roof adds significant value to your home.

Foot Traffic

An immediate consideration is that foot traffic, including gutter cleaning, solar installations, etc., can cause roof tile cracks. A qualified roofer can immediately replace cracked tiles before any further damage starts.


Within as soon as ten years, the pointing of your roof can start showing signs of cracking (further worsened by foot traffic). A quick pointing touch-up is a simple way to prevent further damage.

Accumulated Grime

Within ten years, the first signs of moss and lichen will start to show (particularly in moist environments). A periodic powerwash is the best way to keep your roof looking fresh.

Dislodged End Cap

Usually one of the first things to go, your ridge cap end tile can start to feel the weight of gravity and begin to slide. This is an easy fix at this stage.

Cracked Pointing

More extensively cracked and peeling ridge pointing will start to show, exposing the mortar under your hip tiles (ridge caps). Should you address the issue soon enough, a qualified roofer could save the bedding with a cost-effective pointing touch-up.

Dislodged Flashings

Your roof’s flashings can become dislodged over time and may need replacement. A simple installation of a lead-free, adhesive flashing is a cost-effective way to prevent further damage.


At a minimum, we recommend a roofing inspection of your roof to have any routine maintenance complete and ensure your roof is in functional condition.

Accumulated Grime

Moss and lichen will continue to grow, making your roof look lacklustre and contributing to cracking of your pointing. A simple roof clean by an expert is a great way to nip this issue in the bud.

Dislodged Shell Cap

If your end ridge tile is not addressed soon, it can continue to slide and allow the tiles it sits on to begin to slide into your gutter.

Loose Ridge Caps

Ridge caps are likely loose at this point. When this occurs, complete cleaning and replacing bedding cement is required to ensure the ridges are refastened and stay in place.

Degraded Pointing

If left unattended, the pointing of your ridge caps (at a bare minimum) needs replacing to keep your ridge caps secure.

Faded Colour

With age, all roofs will lose their colour/glaze. Restoring this is for cosmetic purposes, but when all maintenance is completed, followed by re-sealing and painting, it will add a new lease of life to an old, bland roof.

Dislodged End Cap

By this stage, your end cap could have continued to slide off, leaving no weight on its under tiles. This not only looks terrible but also allows water ingress.

Replacement Required

At this point, your roof may be beyond repair. Moss could have penetrated under your tiles, unattended mechanical stress could leave your tiles riddled with cracks, and your ridge caps likely need complete repair. Unfortunately, complete reroofing may be the only solution.

Use our interactive tool to explore the long-term benefits of quality roofing:

Leak Protection

The roof tiles are designed to allow rain to run freely off your roof and into your gutter to prevent pooling on your roof’s surface.

Controlled Runoff

Your roof’s valleys act as a securely sealed, free-flowing channel to allow stormwater to run seamlessly into your gutters.

Leak Protection

The ridges of your roof are fastened with bedding cement and sealed with pointing mortar to prevent water ingress.

Leak Protection

Flashings are small pieces of metal placed around your roof’s joints to act as a tight and secure waterproofing barrier.

Weather Damage

Strong winds caused by storms can dislodge valley tiles. Having an expert roofer clip these back into place is an easy and cost-effective way to avoid further damage.

Accumulated Debris

Within ten years, debris and organic matter will start to fill in your gutter, increasing the chances of rust and water overflow. A simple, quick emptying of your gutter is the best way to avoid any issues.

Water Ingress

Any cracked and unattended pointing will start to make your roof vulnerable to water ingress, with a high chance of leaks beginning to move through your ceiling and into your attic.

Lost Flashings

Flashings aged 20 years are highly sensitive to wind gusts, proving a prime access point for water infiltration.

Dislodged Tiles

At the 20-year mark, multiple roof tiles are likely to become dislodged. Having an expert lock them in place is a simple way to prevent leaks.

Soaked Insulation

At this point, unattended leaks are already soaking your ceiling insulation, making it an excellent breeding ground for mould and rendering the insulation effectively useless.

Mouldy Insulation

If exposed to moisture, your ceiling insulation has heavily degraded and is likely full of mould. Degraded insulation is an excellent breeding ground for mould and could be promptly replaced to keep your indoor space healthy and comfortable.

Water Ingress

Unattended ridge caps with deteriorated pointing and bedding are a leading reason for water ingress and leaks coming through your ceiling.

Interior Damage

Any unattended leaks will show on your ceiling and walls as yellow stains and mould. An expert professionally treating your home for mould and water stains is costly…

Electrical Hazard

Unattended leaks are a significant electrical hazard and could be dripping onto electricals. If exposed to water, this poses a considerable fire risk and likely needs complete replacement.

Attic Damage

An unattended roof will likely allow multiple entry points for water ingress into your ceiling. Wood rot of your trusses could be a significant issue at this point, and the plaster of your ceiling may need complete replacement.
