Bedding On A Roof With Red Tiles

Roof Repointing and Rebedding: What Is It (and Which Do You Need)

ByNick

Your roof does more than keep the rain out; it protects your home from the elements, supports insulation, and plays a major role in curb appeal. But over time, like anything exposed to Rockingham’s mix of sun, sea air, and occasional storms, your roof needs a little TLC to stay in top shape.

Two critical maintenance tasks that often get overlooked are roof repointing and rebedding. These terms might sound technical, but understanding them could save you a lot of trouble (and money) down the track.

So, what exactly are repointing and rebedding, and how can you tell if your roof needs them? Let’s break it down to terms that anyone can understand.

What Is Roof Rebedding?

Rebedding is all about securing the ridge tiles on your roof.

But first, let’s see what roof bedding is.

The thing is, ridge tiles sit along the highest points of your roof, forming the backbone of its structure. These tiles are held in place by a cement mixture called bedding, which keeps them stable and weatherproof.

Over time, this bedding can crack or crumble due to age, weather exposure, or movement caused by temperature swings. Outcome? The tiles can become loose, so your whole roof becomes more vulnerable to leaks and structural damage.

When Does Your Roof Need Rebedding?

  • Loose Tiles: If you notice ridge tiles shifting out of place or rattling on windy days, it’s a strong sign the bedding needs attention.
  • Visible Cracks: Check for gaps or cracks in the cement around ridge tiles. Even small cracks can let water seep in, causing bigger problems later.
  • Ageing Roofs: If your roof hasn’t been serviced in 10-15 years, it’s worth inspecting the bedding as part of regular maintenance.

Note, however, that roof rebedding doesn’t mean replacing your entire roof. On the contrary: it’s a targeted fix that ensures your ridge tiles stay put.

In many cases, rebedding is paired with repointing for a complete refresh. Which brings us to the next question.

What Is Roof Repointing?

Repointing is the next step after rebedding and involves applying a flexible material over the bedding to seal and strengthen it.

In other words, once the backbone of the roof is in place, you’ll repoint to reinforce it.

Traditionally, cement was used for this task, but these days, most professionals opt for flexible pointing compounds. These materials are better at withstanding the natural expansion and contraction that comes with changes in temperature—something we’re all too familiar with during our hot Perth summers.

Benefits of Repointing

  • Improved Weather Resistance: Repointing seals your roof against the elements. Wherever you live, they’ll gradually eat away at the roof. Especially where there’s salt involved!
  • Enhanced Stability: By locking ridge tiles securely in place, repointing reduces the risk of their coming loose in a storm.
  • Longer Lifespan: Once a roof is well pointed, it can last for decades with minimal maintenance.

How to Tell If You Need Roof Repointing or Rebedding

The best way to know if your roof needs attention is to keep an eye out for common warning signs. Here’s what to look for:

  • Leaks or Damp Spots Indoors: Water stains on your ceilings or walls could mean your roof’s ridge tiles aren’t sealed properly.
  • Cracked or Missing Mortar: If the cement around your tiles looks crumbly or has chunks missing, it’s likely time for rebedding and repointing.
  • Shifting Tiles: Notice any ridge tiles that seem loose or out of alignment? That’s a clear sign the bedding has deteriorated.
  • General Wear and Tear: If it’s been years since your roof was last inspected, it’s worth getting a professional to check for hidden issues.

Why Is It Especially Important in Rockingham (& Thereabout)?

Rockingham’s coastal location means your roof has a special diet of elements. Apart from rains and storms and the sun that are there in any part of the world, there’s also the salty air to deal with.

The salty air can accelerate wear on bedding and pointing materials, while the strong winds that occasionally whip through the area can loosen ridge tiles. Add to that the scorching summer sun, and it’s easy to see why keeping your roof in good shape is so important here.

What starts as a tiny issue can quickly snowball into something way more expensive and stressful, especially during the wetter months when heavy rain can exploit even the tiniest gaps in your roof’s defences.

So regular maintenance, including repointing and rebedding, is key to dodging expensive fixes or even a full roof replacement down the track.

Can You DIY Repointing or Rebedding?

While it might be tempting to tackle roof repairs yourself (like the guy above does), repointing and rebedding are best left to the pros. Working at heights is inherently risky, and making sure the job is done well calls for specific tools and expertise.

A professional roofer will:

  • Safely access your roof using proper equipment.
  • Remove old, damaged bedding and replace it with fresh material.
  • Apply flexible pointing compounds for a long-lasting seal.
  • Inspect the entire roof for other potential issues while they’re up there.

Trying to cut corners with a DIY job might save money upfront, but it can end up costing more if mistakes lead to leaks or structural damage.

Think of it this way: if you don’t wash your own roof because it’s not safe enough, repairing is even less safe.

How Often Should You Have Your Roof Repointed and Rebedded?

There’s no one-size-fits-all answer, as the lifespan of your roof’s bedding and pointing depends on factors like age, weather exposure, and the materials used. However, most roofs will thank you if you give them a once-over every 10 years or so. Catching issues early can save you from more extensive repairs later.

If you’re unsure about the state of your roof, it’s always better to err on the side of caution. A quick inspection could mean the difference between a minor fix and a major headache.
