Ridge Capping in Adelaide – What It Is, Repairs & Costs

What Is Ridge Capping?

Ridge capping is the row of protective tiles or metal sheeting that runs along the very top of your roof. It covers the joint where two roof slopes meet, sealing the ridge against water and wind while giving the roof a neat, finished look.

In Adelaide, ridge caps are commonly made from terracotta, concrete, or metal such as Colorbond. Some modern systems use dry-fix methods that don’t require mortar, but traditional bedding and pointing remain the most common.

Think of ridge capping as the crown of your roof — small in size, but critical to protecting everything below.

Why Ridge Capping Matters for Your Roof

Ridge capping isn’t cosmetic; it’s structural protection. Without it, your roof is vulnerable to leaks, damage, and movement. It provides:

Weather defence — blocks rain, wind, dust, and storm debris.
Leak prevention — protects one of the most common points of roof failure.
Pest control — keeps birds, rodents, and insects out of the roof cavity.
Tile stability — helps hold adjoining roof tiles in place.
Visual finish — makes the roofline straight and consistent.

Ignoring ridge capping issues can quickly lead to expensive structural repairs.

Bedding, Pointing & Repointing Explained

Ridge caps are held in place by mortar, in two key layers:

Bedding — a sand-cement base layer that secures ridge caps to the roof.
Pointing — a top coat of mortar or flexible compound such as DULUX acratex that seals and finishes the bedding.

Over time, these layers break down. When this happens:

Repointing replaces only the pointing if bedding is still strong.
Rebedding replaces both layers when bedding has failed.

Today’s flexible pointing compounds expand and contract with roof movement, lasting far longer than old rigid mortars.

Common Ridge Capping Problems

Adelaide homeowners often don’t notice ridge capping issues until leaks appear. The most common problems are:

Cracked or crumbling mortar.
Loose or displaced ridge caps after storms.
Visible gaps where water or pests can enter.
Moss or algae growth along ridge lines.
Damp patches on ceilings caused by leaks.

Causes of Ridge Capping Damage

Australian conditions are tough on roofs. Ridge capping damage is usually caused by:

UV and heat — mortar becomes brittle in Adelaide’s hot summers.
Heavy rain and storms — loosen bedding and shift caps.
Coastal exposure — salt air corrodes metal capping.
Poor installation — weak bedding or incorrect pointing.
Natural movement — timber frames expanding and contracting.

Signs Your Ridge Capping Needs Repair

Look out for these red flags:

Cracks in the pointing mortar.
Loose or rattling ridge caps in the wind.
Water stains or leaks on ceilings.
Mortar fragments washing into gutters.
Ridge tiles visibly out of alignment.

If you see any of these signs, it’s time for repairs before further damage sets in.

How to Fix Ridge Capping

Repairs usually involve one of three approaches:

Repointing — renewing the pointing only.
Rebedding — removing and replacing bedding and pointing.
Replacement — installing new ridge caps if old ones are damaged.

Professionals use flexible compounds and correct mortar application to ensure long-term results.

How Long Does Ridge Capping Last?

The lifespan varies by material and environment:

Concrete ridge caps — 20–30 years.
Terracotta ridge caps — 30–40 years.
Metal ridge caps — 30+ years but prone to corrosion near the coast.

In South Australia, most roofs need repointing every 10–15 years due to heat and UV damage.

How Much Does Ridge Capping Repair Cost in Adelaide?

Prices vary by roof size, pitch, material, and the extent of damage:

Small repointing jobs — from $700 to $1,500.
Full ridge repointing — $1,500 to $3,000.
Complete rebedding — $2,500 to $4,500+.

Some roofers charge per lineal metre, typically $20–$25. Investing early in maintenance is always cheaper than waiting for leaks.

Can You DIY Ridge Capping Repairs?

DIY repairs are possible, but risky. Common mistakes include:

Using the wrong mortar mix.
Applying rigid pointing that cracks quickly.
Covering issues instead of fixing weak bedding.

Working at heights is also dangerous. For safety and lasting results, ridge capping should be left to licensed roofers.

Preventative Maintenance Tips

You can extend ridge capping life by:

Inspecting every 5 years, or after storms.
Clearing gutters to reduce water stress.
Removing moss and algae early.
Using flexible pointing compounds during repairs.
Acting on cracks before they spread.
