Roof leaks can be a homeowner’s nightmare, potentially causing significant damage if left unaddressed.
Let’s explore the most common causes of roof leaks.
1. Broken or Missing Tiles
Broken or missing tiles leave your roof vulnerable to water leaks. This can happen due to severe weather, falling debris, or simply age-related wear and tear.
2. Damaged Flashing
The ridge capping at the peak of your roof can crack over time, allowing water to enter your home. Rebedding and Pointing are essential repairs to ensure the integrity of the ridge capping.
Rebedding involves removing the old mortar and laying a new bed of mortar to secure the ridge caps.
Pointing involves applying a fresh layer of mortar over the existing bed to seal any gaps and prevent water ingress.
Regularly performing these tasks can help maintain the durability and weatherproofing of your roof.
3. Cracked Ridge Capping
The ridge capping at the peak of your roof can crack over time, allowing water to enter your home.
4. Blocked or Damaged Gutters
When gutters are clogged or damaged, water can overflow, leading to potential leaks into your roof structure or seepage into your home’s foundation. This can cause long-term structural damage and increase the risk of mould growth.
5. Storm and Wind Damage
Severe weather can cause immediate damage to your roof, from lifting tiles to creating holes that lead to leaks.
High winds can also dislodge gutters and downpipes, while heavy rain can lead to significant water ingress and potential structural issues.
6. Damaged Sarking
Sarking, the protective layer under your roof tiles, can deteriorate over time, compromising your roof’s ability to repel water.
7. Wear and Tear
As roofs age, they become more susceptible to leaks due to general wear and tear, exposure to harsh weather conditions, and potential damage from falling debris.
Roof Statistics
Age-Related Wear and Tear
As roofs age, they are more prone to leaks due to general wear and tear. Studies show that over 70% of homes older than 20 years experience some form of roofing issue, often linked directly to ageing materials.
Broken or Missing Tiles
Research indicates that approximately 25% of reported roof leaks in Australia are due to broken or missing tiles, particularly after severe weather events like storms or hail.
Poor Flashing Installation
Flashing issues account for around 15% of all roof leak incidents in Australia, highlighting the role of proper flashing installation during initial construction or repairs.
Blocked Gutters
It’s estimated that up to 30% of homeowners neglect regular gutter maintenance, leading directly to leaks during heavy rainfall.
Storm Damage
Severe weather events are responsible for nearly 40% of roof damage claims in Australia, highlighting the need for prompt repairs following storms to prevent leaks.
Damaged Sarking
Studies show that over 20% of roofs with deteriorating sarking experience leaks, especially in humid conditions common in coastal areas like Sydney’s North Shore.

Homes that undergo annual inspections are 50% less likely to experience significant leak-related damage, according to industry reports from Australian roofing associations.
