Your roof adds to your home’s aesthetics and is also a defense line against the entire structure. It protects your property from rain, storms and harsh sunlight. Overtime, natural wear and tear affects the structure especially around ridge capping. That’s where two critical roof maintenance services come into the picture – roof repointing and roof rebedding.
Both of these services go hand in hand when it comes to roof maintenance and restoration, but both are unique in their own way. Understand the difference between rebedding and repointing and when each service is required to save yourself from the expensive and emergency roof leaks repair.
What is Roof Re-Bedding?
Roof re-bedding is the process of replacing and removing cement mortar known as bedding. It holds ridge caps in place. The ridge caps are angled tiles located at the tiled roof, covering the joints where roof surfaces meet.
What Makes a Roof Bedding Fail?
Cement bedding deteriorates overtime due to following reasons:
- Continuous exposure to extreme weather
- Structural movements or settling of the house
- Bad quality of original installation
- Accumulated debris and moss with moisture.
When the bedding is cracked, the ridge caps go loose and are misaligned making your roof vulnerable to water seepage, tile displacement and even ceiling damage from the inside.
When do you need Roof Re-Bedding?
- Loose, cracked and missed ridge caps
- Gaps between ridge lines and roof
- Crumbling and Mortar Deterioration
- Frequent roof leakage and water stains on the ceiling
- Debris in the form of mortar granules in gutters
Process of Re-Bedding:
- Ridge caps removal
- Clearing the old bedding mortar
- Applying the fresh roof bedding
- Ridge caps replacement and alignment security
- Allocating some time before repointing if required
What is Roof Repointing?
Roof repointing is about the application of a flexible pointing compound over existing bedding. The compound is designed for expanding weather changes unlike the traditional cement that can break under pressure.
Repointing is usually done after re-bedding and as a preventive maintenance step when the bedding is strong enough but has started showing surface level deterioration.
Flexible Pointing Benefits:
- Adaptive to changing temperatures
- Seals cracks even of hairline nature
- Stops moisture from penetrating the mortar
- Extending ridge cap life
When Do You Need Roof Repointing?
- Small cracks in ridge caps
- Discolored or Patchy mortar
- Water leakage during heavy rain
- Strong windstorms and hail events
- General roof aging (over 10+ years)
Process of Repointing:
- Cleaning the existing bedding
- Removal of loose pointing
- Application of flexible roof compound pointing
- Sealing for a smooth finish
Roof Repointing vs. Re-Bedding: What are the Differences?
Here’s a simple breakdown:
| Feature | Roof Re-Bedding | Roof Repointing |
| Purpose | Replace deteriorated mortar | Seal and reinforce existing mortar |
| Material | Cement mortar | Flexible pointing compound |
| When Needed | When ridge caps are loose or bedding is crumbling | When bedding is intact but cracking on the surface |
| Cost | Higher due to labor and material | Lower, faster job |
| Frequency | Every 20–25 years | Every 10–15 years |
| Common With | Full roof restoration | Preventative maintenance |
When Do You Need Both the Services?
Roofing contractors suggest using both services when the redding is compromised. That’s because repointing without re-bedding is ineffective. Re-bedding has a structural base whereas repointing ensures waterproofing.
You require both if:
- You are selling your property and want to enhance curb appeal
- You are putting your property up for sale and enhance its aesthetics
- Your home is damaged by strong rain and hail storms
- You have done roof tiles repair and restoration already
Why You Can’t Ignore These Services?
Neglecting the damaged ridge would lead to
- Weekend roof structure
- Internal water damage
- Mould in insulation and ceilings
- Decreased property value
- Pest infestation such as ants, wasps , bees etc
Maintaining your roof with timely re-bedding and repointing will add life years to ensure protection for family during harsh weather conditions.
How Much Does a Roof Repointing or a Re-Bedding Cost in Australia?
Costs vary depending on your roof size, pitch, and location. It’s recommended to request a roof inspection from a licensed roofing specialist in Canberra.
Wrapping Up: Which One Do You Need?
When a mortar is cracked but is still stable, you can opt for repointing.
If ridge caps are deteriorated, you can choose repointing and re-bedding.
Choose both rebedding and repointing if you want a perfect roof for a long-term.
