Tile slippage is one of the most common issues faced by homeowners with older properties in South Cerney. While it may seem like a minor inconvenience at first, slipped tiles expose the roof to water ingress, draughts, and structural deterioration. Older roof structures, in particular, are more susceptible due to ageing fixings, weathered battens, and shifting roof geometry over time.
Understanding why tiles slip—and how to prevent it—can help homeowners protect their property and avoid more serious damage later on.
Why Older Roofs Are More Prone to Tile Slippage
As a roof ages, several components begin to weaken. Even if the tiles themselves remain intact, the supporting structure can deteriorate.
Common causes include:
- Worn or decayed battens that no longer hold tiles securely
- Corroded fixings that have weakened with age
- Movement or sagging in the roof structure
- Long-term exposure to wind uplift
- Mortar deterioration on older ridge and hip tiles
These issues typically develop slowly but eventually create enough movement for tiles to slip out of position.
Strengthening Battens and Fixings
One of the most effective ways to prevent tile slippage is to ensure the battens and fixings beneath the tiles are strong enough to support them properly. On older roofs, these components are often the first to fail.
A roofing professional can:
- Replace damaged or weakened battens
- Upgrade fixings to modern standards
- Ensure the roof covering is securely anchored
This brings the roof back in line with current installation practices, improving long-term stability.
Addressing Roof Movement and Structural Fatigue
Roof structures naturally shift over time due to age, moisture, and seasonal temperature changes. When movement occurs, tiles can become dislodged or sit unevenly.
A professional roofing assessment can identify:
- Areas of roof sagging
- Rotting or compromised timbers
- Places where additional support is needed
Stabilising the structure beneath the tiles is essential for preventing repeated slippage.
Improving Ventilation to Reduce Moisture Damage
Poor ventilation can lead to condensation, which accelerates timber decay and weakens battens. Proper airflow allows the roof to stay dry and stable, particularly in older homes where ventilation may not have been part of the original design.
Improved ventilation helps:
- Prevent internal moisture build-up
- Maintain the integrity of the roof structure
- Reduce long-term deterioration that leads to slippage
Re-Bedding and Re-Pointing Ridge and Hip Tiles
Many older roofs rely on mortar at key joints. When this mortar cracks or deteriorates, ridge and hip tiles become loose, increasing the risk of displacement.
Re-bedding or re-pointing these areas prevents:
- Water ingress
- Wind uplift
- Progressive tile movement
It also strengthens the roof’s overall weather resistance.
Scheduled Roof Inspections Make the Biggest Difference
Tile slippage tends to start small, often unnoticed from the ground. Regular roof inspections ensure that issues are caught early, before they develop into leaks or structural damage.
Inspections are particularly valuable for:
- Homes over 40 years old
- Properties exposed to strong winds
- Roofs with previous repairs
Early intervention is always more effective than waiting for obvious signs of damage.
Conclusion
Preventing tile slippage on older roof structures requires a combination of strong fixings, sound structural support, proper ventilation, and ongoing maintenance. For homeowners in South Cerney, taking proactive steps now can protect the property from leaks, draughts, and expensive long-term damage.
