Slipped and broken roof tiles are one of the most common reasons homeowners in Caerphilly call out a roofer. A single displaced tile can seem minor, but it is often a sign of wider wear and, left alone, it opens the roof up to water ingress that can cause far more damage than the tile itself.
Understanding what causes tiles to slip or crack in the first place can help you spot problems early and know when it is time to get a professional opinion rather than leaving it and hoping for the best.
Common causes of tile damage
Wind is the most frequent culprit. Caerphilly's position, with its mix of exposed valley sides and higher ground, means roofs can take a real battering during storms, and strong gusts can work tiles loose or lift them enough to snap the fixings holding them in place. Over time, even without a dramatic storm, repeated wind pressure gradually loosens tiles that were originally fixed securely.
Age and weathering play a big part as well. Tiles become more brittle over the years as they are exposed to repeated freeze-thaw cycles, rain and UV exposure, which makes them more likely to crack under pressure that a newer tile would shrug off. The nails or fixings holding tiles in place can also corrode or perish with age, allowing tiles to work loose even without any obvious external cause. Physical damage from fallen branches, debris in high winds, or even birds and animals can crack or dislodge tiles too, and poor original installation or the wrong fixing method for a particular roof pitch can leave tiles vulnerable from the start.
The roof's aspect and exposure also make a difference. A roof slope that faces the prevailing wind and weather will generally take more punishment over time than a sheltered slope on the same property, which is why tile damage is sometimes concentrated on one side of a roof rather than spread evenly across it. Roofs on higher ground or in more exposed parts of Caerphilly can see this effect more noticeably than those in sheltered valley locations.
What to do if you notice a problem
If you spot a slipped or broken tile on your Caerphilly property, it is worth having it looked at promptly rather than waiting. A missing or cracked tile leaves the underlay and timbers beneath exposed to the weather, and what starts as a small repair can quickly become a bigger job if water gets in and causes rot or damp. Climbing up to inspect or fix it yourself is not something we would recommend given the risks involved with working at height.
