So, How often should I get my roof repointed?

Repointing is an important part of roof maintenance that keeps your property protected from the elements. Over time, the mortar between roof tiles, ridge caps, or brickwork can weaken and crumble, leaving gaps where water can seep in. If you have ever wondered “how often should I get my roof repointed?”, understanding the signs, timing, and process can help you maintain a strong and watertight roof.

What Is Roof Repointing?

Repointing involves renewing the mortar that holds roof tiles or ridge caps in place. Mortar is essential for sealing gaps and preventing water penetration, especially in ridge tiles that sit along the top of the roof.

As your roof ages, exposure to wind, rain, and temperature changes causes the mortar to deteriorate. When this happens, repointing restores the strength and stability of the roof structure, preventing leaks and further damage.

Why Repointing Matters

The mortar between your tiles is the first line of defence against moisture. Once it starts to crack or fall away, water can easily enter and damage the roof’s underlay or timbers. Repointing keeps your roof watertight and extends its lifespan by protecting it from:

• Water leaks and damp patches inside the home

• Loose or unstable ridge tiles

• Mould or moss growth in gaps

• Wind damage from unsecured tiles

A well-maintained roof not only prevents costly repairs but also improves your property’s appearance and value.

How Often Should Roofs Be Repointed?

Most roofs should be repointed approximately every twenty to thirty years, depending on their exposure and the quality of the original mortar. However, this can vary depending on several factors:

• Age of the roof: Older roofs may require more frequent maintenance.

• Weather exposure: Coastal areas such as Lancing and Worthing face stronger winds and salt air that wear down mortar faster.

• Roof design: Roofs with steep pitches shed water more easily and may last longer between repointing.

• Maintenance history: Regular inspections and cleaning help spot issues early, extending the life of the mortar.

It’s best to have your roof inspected every few years so a professional can assess whether repointing or other repairs are needed.

Signs That Your Roof Needs Repointing

Knowing when to act is key to avoiding major damage. Common signs that your roof needs repointing include:

• Cracks or gaps in the mortar around ridge tiles

• Loose or wobbly ridge caps

• Bits of mortar found in gutters or on the ground

• Water stains or damp patches on ceilings

• Moss growing between tiles or around mortar joints

If you notice any of these symptoms, it’s time to arrange a professional inspection.

The Roof Repointing Process

Professional repointing involves several careful steps to ensure lasting results. Roofers will:

1. Inspect the roof to identify all damaged mortar.

2. Remove any loose or crumbling material using safe methods.

3. Clean the area thoroughly to allow new mortar to adhere properly.

4. Apply a fresh mortar mix, matching the colour and texture of the original.

5. Finish and smooth the joints for a neat, weatherproof seal.

Quality workmanship ensures that the new pointing blends seamlessly with the existing roof and provides long-term protection.

Repointing vs Rebedding

While repointing replaces only the surface mortar, rebedding involves removing and resetting the ridge tiles entirely before applying new mortar. Rebedding is required when the tiles have become loose or the bedding beneath them has failed.

In many cases, only repointing is necessary if the ridge tiles are still firmly set but the mortar surface has cracked. A roofer can advise whether repointing alone will be sufficient or if full rebedding is needed.

How Repointing Helps Prevent Leaks

One of the most common causes of roof leaks is deteriorated mortar around ridge tiles. Once cracks appear, rainwater can run beneath the tiles and into the roof space. Repointing seals these weak spots, preventing leaks before they start.

In some cases, small cracks may appear harmless, but they can widen quickly due to frost, movement, or wind pressure. Early repointing is always more cost-effective than waiting until damage spreads.

Combining Repointing with Other Roof Maintenance

Repointing is often carried out alongside other maintenance tasks to keep your roof in top condition. For example:

• During roof repairs, roofers can inspect the mortar and repoint as needed.

• If you are upgrading tiled roofs, repointing ensures the ridge line matches the new tiles.

• Moss removal before repointing helps new mortar bond properly and prevents regrowth.

Scheduling these services together saves time and ensures every part of your roof remains strong and well maintained.

Choosing the Right Roofing Professional

Repointing requires skill and experience to achieve lasting results. Using a local roofer familiar with Lancing’s weather conditions ensures the right materials and techniques are used.

Before hiring, check that the company:

• Has experience with repointing and rebedding

• Uses high-quality mortar suitable for local weather conditions

• Provides a clear written quotation

• Is insured and has positive reviews

How Long Does Repointing Last?

When completed by experienced roofers using quality materials, repointing can last twenty years or more. Regular cleaning and inspection help maintain its condition and prevent cracks from developing prematurely.

If your roof faces heavy coastal weather or frequent storms, scheduling periodic checks can ensure the mortar remains strong and intact.

Preventing Future Mortar Damage

A few simple maintenance steps can extend the life of your roof pointing:

• Keep gutters and downpipes clear to prevent water overflow.

• Remove moss or algae that can hold moisture against the mortar.

• Check for loose tiles after heavy storms.

• Arrange routine inspections to catch early signs of wear.

Preventive care not only reduces repair costs but also helps maintain your roof’s overall appearance.

Conclusion

So, how often should you get your roof repointed? For most properties, every twenty to thirty years is a good rule of thumb, though factors such as location and weather may affect this. Regular inspections ensure that small cracks are addressed before they lead to major leaks or damage.
