Roof repairs
Slipped tiles, leaks, valleys and flashings put right before they get worse.
In short
Most roof leaks come from a small number of predictable places: slipped or cracked slates, failed lead flashing where the roof meets a wall or chimney, blocked or split valleys, and worn mortar on the ridge. A roof repair means finding which of those is actually letting water in and putting it right, rather than sealing over the wet patch and hoping. Most single repairs are a same-day job.
A leak rarely shows up directly below the hole. Water runs down the inside of the roof and along the timbers before it drips, so the stain on your ceiling can be a fair distance from the actual fault. That is why finding the cause matters more than patching the symptom.
Common causes of a leaking roof
- Slipped, cracked or missing slates and tiles
- Failed lead flashing where the roof meets a chimney or wall
- Blocked, split or badly formed valleys between two roof slopes
- Cracked mortar on the ridge or at the verge
- Overflowing gutters pushing water back under the bottom course
- Perished felt at the eaves letting water past the gutter line
What the job involves
Every roof is different, but the shape of the work is usually the same. Here is how a typical roof repairs job runs.
Find the actual source
We trace the leak back from where it shows inside to where the water is really getting in, checking the loft as well as the roof itself.
Tell you what we find
You get a straight answer on whether it is a repair or whether the roof is coming to the end of its life, with photos of what we have found.
Carry out the repair
Slates refixed, flashings redressed or replaced, valleys cleared or reformed, mortar cut out and made good as needed.
Check it holds
The surrounding area is checked at the same time so you are not calling us back out for the next fault along.

Frequently asked questions
How quickly can you look at a leak?
Call or send a photo on WhatsApp to 07718 155997 and we will tell you how soon we can get to you. Active leaks in wet weather are treated as urgent, because water sitting in a ceiling causes far more damage than the original fault.
Can you repair a roof in the rain?
A temporary cover can usually go on straight away to stop water getting in, but permanent work such as bedding mortar or dressing lead needs dry conditions to be done properly.
Is it worth repairing an old roof?
If the covering is sound and the problem is in one area, a repair is usually much better value. Once slates are slipping in several different places and the felt underneath has broken down, repeated repairs cost more over a few years than replacing the roof once.
Do you find the leak before quoting?
Yes. Quoting for a roof leak without establishing where the water is actually getting in is guesswork, and it is how people end up paying for work that does not fix the problem.
Why does my roof only leak in heavy or driven rain?
That usually points to a fault that only lets water past at a certain angle or volume, such as a gap under a flashing, a hairline crack in a tile, or a valley that overtops when it fills. It is a real fault and it will get worse, even though the roof seems fine most of the time.
