Maesteg sits in a valley that catches its fair share of wind and driving rain, and many of the town's older terraced and semi-detached houses still carry their original slate roofs. When the weather turns, it is common to spot a slipped or missing slate on the ground, or a gap appearing on a roof slope. This does not always mean the roof has failed completely, but it is a sign that something needs looking at before the next spell of bad weather does more damage.
Slate is a durable and attractive roofing material, and many Maesteg roofs have carried their slates for decades. Over time, though, the fixings that hold each slate in place come under repeated strain from wind, rain and temperature changes, and this is usually where the trouble starts rather than with the slate itself.
The main reasons slates come loose
The most frequent cause is nail fatigue. Slates are traditionally fixed with nails, and after many years those nails corrode or work loose, especially on roofs facing the prevailing weather. Once a nail fails, the slate below it has nothing holding it in place and a gust of wind is often all it takes to send it sliding or off the roof entirely.
Wind uplift is another major factor, particularly on exposed elevations or where a roof has lost its wind resistance over time as timbers and fixings age. Damaged or perished roofing felt underneath the slates can also allow more movement than the roof was designed for, since the felt is meant to provide a secondary barrier as well as some support against wind getting underneath. Cracked or delaminating slates, often from age or from being walked on incorrectly, are weaker points that fail first when the weather is at its worst. Ridge tiles and verges in poor condition can also let wind get underneath the roof covering and lift slates from the edges inward, which is why a roof can sometimes lose several slates in one storm rather than just one.
Maesteg's position in the valley means properties can experience quite different wind exposure depending on where they sit and which way their roof slopes face. A roof that has stood for many years without issue can still be vulnerable if age has quietly weakened its fixings, so a run of bad weather is often when hidden problems finally show themselves.

If you have noticed slipped or missing slates on your Maesteg property, it is worth having the roof looked at properly rather than just replacing the obvious gap, since a single lost slate can point to wider fixing failure across that slope.
