What Is Roof Bedding and Pointing?

Learn about Essential Maintenance for Tile Roofs

Understanding Tile Roofs in New Zealand

Tile roofs are known for their durability and long-lasting beauty, but even the best tile roofs require regular maintenance to stay weatherproof and structurally sound. One of the most important — and often overlooked — parts of tile roof maintenance is roof bedding and pointing.

In this guide, we’ll explain exactly what bedding and pointing are, why they’re essential for tile roofs, and how Auckland homeowners can protect their homes with our professional bedding and pointing services.

What Is Roof Bedding?

Roof bedding refers to the layer of cement mortar that holds the ridge tiles (the ones that run along the peak of your roof) in place. It acts as a foundational support, keeping those tiles secure and aligned.

Key functions of roof bedding:

  • Anchors ridge tiles to the roof structure

  • Provides a base for pointing

  • Helps maintain waterproofing at the roof’s peak

Over time, bedding can crack, shift, or deteriorate due to weather exposure, roof movement, or poor original installation.

What Is Roof Pointing?

Roof pointing is the outer layer applied over the bedding, usually made from a flexible compound. It seals the edges of the ridge tiles and provides a smooth, protective finish.

Key functions of roof pointing:

  • Seals joints against water and wind

  • Protects bedding from erosion

  • Enhances the appearance of the roof

Modern pointing compounds are designed to flex slightly with roof movement, reducing the chance of cracking. However, even flexible pointing degrades over time and needs to be inspected and replaced when worn.

Why Is Bedding and Pointing Important for Tile Roofs?

While the tiles themselves are very durable, they rely on secure bedding and pointing to stay in place and perform well. When these fail, the integrity of your roof is at risk.

Risks of deteriorating bedding and pointing:

  • Loose or missing ridge tiles

  • Water ingress leading to roof leaks

  • Structural damage to the timber framing

  • Increased risk during high winds or storms

In Auckland, with its variable weather and coastal exposure, these issues can develop more quickly than in other parts of New Zealand.

Common Tile Roofing Issues (and What They Mean)

Even the toughest tile roofs face wear and tear over time—especially in New Zealand’s wet, windy, and UV-heavy climate. Here’s what to look out for:

Cracked or Broken Tiles

Tile cracks can occur from impact, foot traffic, or general aging. If left unrepaired, they allow water to seep through and damage the underlay, leading to leaks and timber rot.

Moss, Lichen & Algae Buildup

Organic growth not only makes your roof look aged, but also holds moisture against the tiles—accelerating surface degradation and encouraging mold inside your home.

Faded or Peeling Paint

Paint doesn’t just add color—it seals and protects. Over time, UV exposure causes tile paint to fade, chalk, or peel, reducing waterproofing and increasing maintenance risks.

Leaky Roof or Damp Ceilings

A common symptom of hidden roof issues—like cracked tiles, failing flashing, or degraded ridge capping. These need urgent attention before they affect internal framing or insulation.

Ridge Caps or Missing Mortar

The ridge line (where tiles meet at the peak) is vulnerable to mortar failure over time. Loose or missing ridge pointing can lead to water ingress and tile displacement during storms.
