Finding a slipped or missing tile does not mean the whole roof needs replacing. In many cases the repair is quick and the rest of the roof is sound. The skill is knowing whether the damaged tiles are an isolated problem or a sign of something larger.
Why tiles slip
Tiles are held by nails and clips, and sometimes just by their own weight and the batten they hang on. Old fixings corrode, battens can rot, and strong wind can lift edges that were already loose. In South Wales, wind and driving rain test a roof regularly, so a tile that was marginal is often the first to go.
When a repair makes sense
If the tiles around the damage are in good condition and the battens and underlay beneath are sound, individual tiles can be replaced or re-fixed. A roofer can match the existing tile as closely as possible. Cracked tiles are replaced rather than patched, and ridge tiles that have lost their bedding can be re-bedded and pointed.
When it points to a bigger problem
If many tiles are slipping across the same slope, the cause may be rotten battens, failed fixings or a covering at the end of its life. In that case, repeated small repairs become poor value. Another warning sign is a sagging roofline, which suggests a structural issue and needs a proper look.
What you can do
Take a photograph of any tiles you can see on the ground and keep them. Do not climb up to look. A roofer can inspect from a ladder or a safe access point and tell you what is needed. A small repair done promptly usually prevents a leak, while leaving it can let water into the loft and ceilings.
