Ridge Capping Repointing & Rebedding — Melbourne

What Is Ridge Capping Repointing?

Ridge caps are the concrete or terracotta pieces that sit along the peak and hips of your roof. Over time, the cement bedding underneath cracks and crumbles due to thermal movement, allowing water to seep in. Repointing involves removing the old, brittle cement bedding and replacing it with a flexible pointing compound that moves with your roof. In Melbourne's climate, where roofs expand and contract daily, flexible repointing is essential to prevent recurring cracks and leaks.

Flexible Pointing vs. Rigid Cement — Why It Matters

The single most important factor in ridge capping longevity is the pointing material. Many Melbourne roofers still use traditional rigid cement — and it fails within years. Here's why we exclusively use flexible compounds:

Flexible Compound ✓

  • Stretches and contracts with temperature changes
  • Lasts 10–15 years in Melbourne's climate
  • Maintains a watertight seal through all seasons
  • Won't crack from thermal movement
  • Colour-matched to your roof tiles
  • One-time cost, long-term protection

Rigid Cement ✗

  • Cannot flex — cracks under thermal stress
  • Typically fails within 3–5 years
  • Creates gaps that let water in
  • Chunks fall into gutters, blocking drainage
  • Requires repeated expensive repairs
  • Most common cause of recurring ridge cap leaks

Melbourne's daily temperature swings cause roofs to expand and contract constantly. A concrete tile roof can move several millimetres across a single day. Rigid cement simply cannot handle this movement — flexible compound is the only reliable long-term solution.

Ridge Capping Cost Guide — Melbourne 2026

Ridge capping repointing is one of the most cost-effective roof repairs. Left unaddressed, cracked pointing leads to water damage costing thousands more. Here's what to expect:

Work Type Typical Cost Notes
Repointing only (standard home) $1,500–$3,000 Mortar bed intact, flexible pointing applied
Rebedding + repointing $2,500–$5,000 Full mortar replacement plus flexible pointing
Large / complex roof $4,000–$7,000 Multiple ridges, hips, and junctions
As part of full restoration Included Rebedding + repointing included in all restorations

Prices are indicative for 2026 and include GST. Your actual quote will depend on the length of ridging, number of hip caps, and whether rebedding is needed. We always inspect free and quote before starting.

Our Ridge Capping Process

1

Roof Inspection & Cap Condition Assessment

We inspect every ridge cap, hip cap, and junction on your roof to assess the extent of deterioration and identify any underlying issues before work begins.

2

Removal of Old Cement Bedding

All cracked, loose, and crumbling cement bedding is carefully removed without disturbing the tiles beneath, leaving a clean surface for re-bedding.

3

Re-bedding With Fresh Mortar

Each ridge cap is re-bedded using a strong, high-quality mortar mix that bonds the cap securely to the roof tiles, restoring structural integrity.

4

Flexible Pointing Compound Application

A premium flexible pointing compound is applied over the mortar, designed to expand and contract with your roof and prevent future cracking for years to come.

Why Roof Restoration Plus for Ridge Capping?

Flexible Compound (Not Rigid Cement)

Unlike rigid cement that cracks within years, our flexible pointing compound moves with thermal expansion and contraction — lasting far longer in Melbourne's climate.

Colour-Matched to Your Roof

We colour-match the pointing compound to your existing roof tiles, ensuring a seamless and visually consistent finish across every ridge and hip line.

Prevents Recurring Cracking

Our method eliminates the cycle of rigid cement cracking every few years. With flexible compounds, your ridge capping stays sealed through seasons of temperature swings.

Frequently Asked Questions — Ridge Capping Melbourne

How much does ridge capping repointing cost?

Ridge capping repointing in Melbourne typically costs between $1,500 and $5,000 depending on the length of ridging, the number of hip caps, and whether rebedding is also needed. A standard single-storey home with one main ridge and two hips is usually $2,000–$3,500. Rebedding (replacing the mortar base underneath) adds to the cost. We provide a free roof inspection and written quote.

What is the difference between repointing and rebedding?

Repointing is replacing the flexible pointing compound on top of the ridge caps — it's the visible sealant that prevents water entry. Rebedding is a more extensive process where the mortar bed underneath the ridge caps is completely removed and replaced with fresh mortar before new pointing is applied. Rebedding is needed when the ridge caps are loose or the mortar has deteriorated badly. Many roofs need both.

Why do you use flexible compound instead of cement?

Traditional rigid cement cracks within a few years because Melbourne roofs expand and contract daily with temperature changes. Flexible pointing compound is specifically designed to move with the roof — stretching and contracting without cracking. This means your repointing lasts 10–15 years instead of 3–5 years with cement, making it far more cost-effective long-term.

How do I know if my ridge capping needs repointing?

Look for visible cracks or gaps along the ridge line of your roof, pieces of cement or mortar in your gutters or on the ground, loose or wobbling ridge caps, or water stains on your ceiling near the roof peak. If your pointing is the old rigid cement type and is more than 5–7 years old, it almost certainly needs replacing. We offer free inspections to assess the condition.

How long does ridge capping repointing take?

Ridge capping repointing for a standard home takes 1 to 2 days. If rebedding is also required, it may take 2 to 3 days as the mortar needs time to set before the flexible pointing is applied. Larger homes or complex roof lines with multiple ridges and hips will take longer. We'll give you a clear timeframe during the quoting process.

Can cracked ridge capping cause roof leaks?

Yes — cracked or missing ridge capping is one of the most common causes of roof leaks in Melbourne homes. The ridge line is the highest point of your roof and takes the full force of wind-driven rain. Even small cracks allow water to seep underneath tiles and into your roof cavity, causing ceiling stains, mould growth, and timber damage over time. Fixing it early prevents costly interior repairs.
