How do I know if my roof needs repairing?
The short answer
A roof usually tells you something has changed before it leaks. Slipped or missing coverings, debris in the gutter, damp patches in the loft and mortar breaking away are all reasons to look closer. None of them proves the whole roof has failed. What matters is whether the change is isolated, spreading, or already letting water in.
What evidence should you look for?
A slate or tile out of line, missing, or sitting proud of the courses around it.
- What it can mean
- The fixing holding it has released, or the covering itself has fractured.
- What else could explain it
- A single unit can be displaced by one gust or by a dislodged branch without anything else being wrong.
- Limitations
- From the ground you can see that a unit has moved; you cannot see whether neighbouring fixings are in the same condition.
Investigate · Inspection needed to confirm
Damp staining, dark timber or daylight visible in the loft after rain.
- What it can mean
- Water is already passing the covering and the underlay.
- What else could explain it
- Loft damp can also come from condensation where ventilation is poor, which looks similar but behaves differently.

What could this mean?
Take the signs together rather than one at a time. One displaced slate on an otherwise tidy roof points to a local fault. The same slate alongside grit in the gutters, several slipped units on the same elevation and crumbling mortar points to fixings or bedding reaching the end of their life across a wider area.
What else could explain it?
- Recent scaffolding, aerial work or a chimney sweep visit can displace coverings without any underlying defect.
- Staining on a ceiling can be historic — dry, fading and unrelated to the current condition of the roof.
What this evidence cannot tell you
Nothing visible from ground level confirms the condition of underlay, battens or fixings. Those need closer inspection before anyone can define a repair scope honestly.
How serious is it? — Investigate
A visible change is a prompt to establish the cause, not evidence that urgent work is required.
If it is left: Small openings tend to widen in wind and let water reach battens and timber, which turns a simple repair into a larger one.
What are the realistic options?
Isolated repair
One defect, sound coverings and fixings elsewhere, no pattern of repeat failures.
Broader repair
Several failures along the same elevation or around a shared detail such as a valley or abutment.
Further investigation
Damp inside with no clear external cause, or a roof that cannot be assessed safely from the ground.
A wider scope should be justified by what the evidence shows, not assumed.

- Roof RepairsA roof repair fixes a localised fault — slipped slates, cracked tiles, failed flashing, a leaking valley or a split flat-roof seam — without replacing the whole roof. Most Cumbrian domestic repairs are completed in a single visit once the true cause of the leak has been identified.
- Drone Roof InspectionsA drone roof inspection surveys a roof using a camera-equipped UAV, producing high-resolution photographs and video of every slope, chimney, valley and gutter without scaffolding, ladders or anyone setting foot on the roof. It is faster, safer and cheaper than traditional access, and produces evidence you can keep.
What should you do next?
Write down what changed and when, photograph it from a safe position at ground level, and ask for an inspection that reports on the surrounding area as well as the obvious defect.
