A roof that copes with showers but drips in a downpour usually has a small weakness being overwhelmed. Here is how leaks arise on Pucklechurch cottages and village houses, and how they are found.
Heavy rain asks a lot of a roof. A short, hard downpour pours water faster than gutters and joints can shed it, and anything marginal gives way. If a ceiling mark appears only after a deluge, the cause is often modest, but it still needs finding.
Why heavy rain is the test
In light rain, water drains gently and trickles off the surface. In a downpour, it floods across laps and into gaps, backs up in valleys and overshoots gutters. A worn flashing or a hairline crack that sheds a drizzle fine will let a good deal through when the volume rises.
Gutters are part of this too. A gutter that coped easily with a light shower can overflow in a cloudburst, and the spill then runs down the wall or back under the tiles at the edge, where it can look like a roof leak. Clearing them regularly stops that, though not from the top of a ladder.
Older village roofs
Many of the older stone and brick cottages and village houses around the centre have roofs that have been patched and re-laid over a long time. Felt underneath may be thin or missing in places, and timbers can be uneven. Those roofs tolerate ordinary rain but struggle when it comes down hard.
Likely entry points
Water seldom drips where it enters. It runs along rafters and felt first. Common sources include slipped tiles, chimney flashings, valleys clogged with debris, and gutters that overflow behind the fascia. A leak beside a chimney breast often points straight at the lead around the stack.
Roofs that have had earlier patches often leak next to the repair, because the patch changed how water runs. Tell us what has been done before, even if it was long ago, since that history helps us read the roof. It also helps to know who did it and roughly when.

- Valleys or gutters blocked and overflowing
- Slipped, cracked or missing tiles and slates
- Gaps at the roof edge where a verge has failed
Looking from inside
Use a torch in the loft to look for daylight, damp patches and dark stains on timbers or felt. Check the rafters nearest the staining and see whether wet marks track downhill. A phone photo helps. Leave the roof itself alone. What you see tells us where to begin looking outside.
Take a few dated photographs of any staining, and note whether it grows after each storm. Even a rough record helps us judge how long the water has been getting in and how far it may have travelled. Add the weather on each day if you can recall it.
Our approach and honest advice
We trace the leak back from the loft, check the covering and details outside, and repair what is actually failing. If a patch will do, we say so. If the roof is tired across a wide area, we say that too, and explain what is urgent and what can wait for another season.
Frequently Asked Questions
Why does my leak only show after a storm?
Because heavy rain finds weaknesses that light rain misses. Gutters overflow, valleys flood and small gaps are overwhelmed. The leak may be minor most days and only noticeable when a lot of water arrives at once.
Can a blocked gutter cause a roof leak?
Yes. If water backs up and spills over the edge or up under the first row of tiles, it can run behind the gutter and wet the fascia, soffit and rafter ends. Keeping them clear matters, though we advise against doing it from a ladder at roof height.
How soon should I act on a leak?
Soon. Water that keeps soaking timbers and insulation can lead to rot and damp well before a stain grows. Early repairs usually stay small and protect the structure of an older building. Early repairs usually stay small and protect the structure of an older building from lasting damage.
