Missing or Slipped Tiles: How Urgent Is It Really?

It can usually wait if

There is a single tile out of place, your roof has felt or underlay beneath, the loft is dry when you check after rain, and the gap is in the middle of a slope rather than at a junction. Book it in, keep an eye on it, and do not let anyone convince you the ceiling is about to come down.

Ring today if

You can see dark timber or daylight through the gap, several tiles have gone in one storm, the missing tile is beside a chimney, valley or ridge, water is already showing inside, or loose tiles are sitting where they could slide off over a path or driveway. That last one is a safety issue as much as a roofing one.

The loft check

Take a torch up an hour or two after heavy rain and look at the underside of the felt below where the tile is missing. Dry means the underlay is doing its job and you have time. Wet trails, dripping nails or a damp batten means water is getting past and it needs sorting now, not next month.

Why gaps spread

Tiles overlap and hold each other down. Lose one and the wind gets under its neighbours, so a single gap after a storm often becomes three by the next one. Old nail fatigue makes this worse: if the fixings have rusted through, tiles start sliding one after another and you are into a wider conversation about the roof rather than one tile.
