Roofs tend to fail quietly for a long time before they fail obviously, so a few checks before winter are worth the effort. Slipped or cracked tiles, moss build-up around ridge lines, and staining on ceilings after heavy rain are the most common early signs.
Guttering is worth checking at the same time — a blocked gutter overflowing against a wall is one of the most common causes of damp that gets misdiagnosed as a roof leak.
If you’re planning a loft conversion or extension in the near future, it’s often worth combining roof repairs with that work rather than paying for scaffolding and access twice.
