What Is Roof Repointing & The Signs Your Roof Needs It


Before a roof restoration

Maintaining your roof is crucial for its overall integrity and longevity and can help you save money on repairs and full roof restorations or replacements later. Among various maintenance tasks, such as cleaning out gutters, fixing mould and rust, or painting, roof repointing is one that shouldn’t be forgotten. Here, we’ll explore the ins and outs of repointing a roof, the costs involved, and signs your roof needs some attention.

What Is Roof Repointing?

You might be wondering, “What is roof repointing exactly?” A roof pointing repair involves fixing and renewing the outer part of mortar joints used in masonry construction, especially that used on roof ridge tiles. Professionals remove old, deteriorated mortar from between roof tiles and replace it with new mortar.

Is Roof Repointing Worth It?

Roof repointing is absolutely worth the investment. While it means an expense upfront, it pays dividends in the long run by protecting the roof, one of your home’s most critical components. A properly repointed roof acts as a key barrier against water, preventing costly issues like leaks, wood rot, mould growth, and structural damage later. Repointing reinforces tile adhesion and stability, too, which helps reinvigorate an older roof.

When done professionally by experienced contractors like our team, roof repointing provides long-lasting value that far outweighs the costs of neglecting this maintenance task. Remember: the roof shelters your entire home, so this worthwhile expense becomes a small price to pay for your peace of mind and to safeguard your most valuable asset.

Why Does Roof Repointing Need to Be Done?

This job needs to be done because weather affects roofs over time. Elements like wind, rain, and temperature fluctuations can cause the mortar that keeps the tiles in place to crack, crumble, and generally erode away. Repointing roof tiles removes the damaged mortar and packs in new mortar to reseal the gaps, secure the tiles, and give your roof a new lease on life.

What’s the Difference Between Roof Pointing and Roof Repointing?

It’s also important to understand the difference between roof pointing and roof repointing. They’re similar, but the difference lies in when each process is completed. When your roof first gets installed, your roofing contractor will handle roof pointing work to ensure the roof’s stability. However, later, roof repointing is done as a maintenance project to renew the original pointing material.

What Is Roof Rebedding?

You might also hear the term “roof rebedding” and wonder about it. Basically, the ridge capping on your roof (the triangular-shaped tiles where two roof areas intersect) is fixed onto the roof by bedding and pointing. The ridge capping is held in position on a bed of cement mortar, referred to as the roof bedding.

The cement mortar can be brittle after time and exposure to the elements, in which case a flexible pointing compound is applied over the roof bedding. When you get this process done, as well as new ridge capping plus new pointing compound (replacement mortar), this is referred to as “rebedding” your roof.

Signs You Need to Have Your Roof Repointed

It helps to know some of the most common signs that you need to start getting quotes for repointing ridge tiles at your property.

  1. Cracked, crumbling, or missing mortar between tiles
    • Look for gaps, holes, or areas where the mortar has totally eroded away or is starting to.
  2. Loose, shifting, or dislodged tiles
    • Tiles that have shifted out of position or alignment may have done so because they’re no longer securely attached due to degraded mortar.
  3. Noticeable vegetation growth on the roof
    • Have you seen moss, grass, or other plant growth taking root in mortar gaps on your roof? If so, this indicates your roof needs work because there could be moisture penetration, and your roof may not have the right water-shedding ability due to a lack of mortar.
  4. Water stains or leaks inside the home
    • Visible water stains on the ceilings in your home or on walls underneath the roof are another sign, as are active leaks or drips when it’s raining. Again, this shows that moisture is getting through the roof, which may be coming from the mortar having eroded.
  5. Age of existing mortar
    • If your home is old or you know the roof hasn’t been worked on for a while, it might be time to hire a professional. Mortar typically needs repointing every 25-30 years, and older mortar is always more prone to deterioration.
  6. Roof damage from harsh weather
    • If you’ve noticed lots of severe storms, hail, high winds, freeze-and-thaw cycles, and other extreme weather in your location, you may have roof issues. Harsh weather can crack and dislodge mortar and accelerate its deterioration.

What Is the Cost of Roof Repointing?

If you know your roof needs some attention, you’ll want a general idea of roof repointing cost. Most contractors charge per square metre, so fees will vary according to the size, shape, and material of your roof. Those that are larger, have a higher pitch, or multiple ridges are generally more time-consuming and harder to work on, so quotes will be higher. As a general range, though, the roof repointing cost on the Gold Coast will be between $100 and $200 per metre, with the average roof costing around $2,000 and upwards.

What’s Next?

Homeowners typically can’t easily see a bird’s eye view of their roofs in order to quickly evaluate their state. However, this doesn’t mean roofs don’t need attention. Roof repointing is a worthwhile investment and something you shouldn’t delay if you want to keep moisture out of your home.

Many people wonder how to repoint a roof and if they can do the job themselves, but due to the level of experience required and safety risks, it’s always best to hire a professional. Feel free to call our friendly team now to discuss your needs and obtain a quote to have this work completed.
