A roof relies on more than just tiles or slates to perform properly. Beneath the surface, a network of fixings holds everything securely in place, ensuring the roof can withstand wind, rain, and seasonal changes. In Tunbridge Wells, Kent, many older properties still rely on original roofing fixings that have been in place for decades. Over time, these fixings naturally lose strength, which can compromise the stability and reliability of the entire roof.
At TW Roofing Solutions, we regularly assess ageing roofs where fixing failure is the underlying cause of recurring or unexplained roofing issues.
What roofing fixings do
Roofing fixings are the components that secure tiles, slates, battens, and other roof elements to the structure beneath. They are designed to resist movement, uplift, and vibration caused by weather exposure. When fixings are strong and intact, the roof covering remains firmly in place and performs as intended.
As roofs age, however, these fixings are subjected to ongoing stress that gradually reduces their effectiveness.
Why fixing strength reduces over time
Long-term exposure to weather
Roof fixings are constantly exposed to moisture, temperature changes, and airborne pollutants. Over many years, this exposure can lead to corrosion, weakening the metal and reducing its ability to hold materials securely. Even fixings that are not visibly rusted may lose structural integrity internally.
Repeated movement and vibration
Roofs expand and contract as temperatures change. Wind also causes subtle movement across the roof surface. Over time, this repeated motion can loosen fixings, enlarge fixing holes, and reduce grip within the roof structure.
Ageing timber beneath the roof
Fixings rely on the strength of the timbers they are anchored into. As roof timbers age, they can dry out, soften, or lose density. This reduces the holding power of nails or screws, allowing tiles and battens to shift more easily.
Older installation methods
Many older roofs were installed using fixing standards that differ from modern best practice. Over time, these older methods may prove less resilient to prolonged exposure and changing weather patterns, particularly during periods of strong wind.
The impact of weakened fixings on a roof
When fixings begin to fail, the effects are often gradual rather than immediate. Tiles or slates may start to move slightly, leading to gaps, uneven surfaces, or increased vulnerability to wind uplift. Water can then find its way beneath the roof covering, affecting underlayers and roof timbers.
In some cases, repeated minor movement places additional strain on surrounding fixings, accelerating overall deterioration across the roof.
Why these issues are common in older roofs
Roofs in Tunbridge Wells often experience a combination of seasonal rainfall, temperature variation, and wind exposure. Over decades, this environment places consistent demands on fixings. Without intervention, even well-installed roofs can reach a point where fixing strength is no longer sufficient to maintain stability.
Regular inspection helps identify early signs of fixing failure before more visible damage occurs.
The importance of professional assessment
Fixing issues are not always obvious from ground level. A professional roofing inspection can identify subtle movement, weakened fixings, or early signs of deterioration that may otherwise go unnoticed. Addressing these issues at the right time helps maintain roof performance and reduces the risk of further disruption.
Local experience is valuable, as roofing systems in Tunbridge Wells, Kent are influenced by specific building styles and environmental conditions.
Conclusion
Old roofs lose fixing strength over time due to weather exposure, repeated movement, ageing timbers, and outdated installation methods. As fixings weaken, the roof becomes more vulnerable to movement, water ingress, and progressive deterioration. Understanding this process highlights the importance of regular professional assessment and timely maintenance.
