About our roof leak investigation in Burnham Green
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot, along with any photos you’ve taken. Even on a dry day, a leak usually leaves clues: stained timbers, tide marks and damp underlay. Moisture readings show where materials are still wet. We survey flat roof details, lead flashings and valleys and parapet gutters, and the problems we’re asked to look at most are damp on a chimney breast and damp ceilings under a flat roof.
In a village or hamlet like Burnham Green, older cottages and farmhouses frequently have roofs that have been patched over many years. That makes it hard to tell new damage from old wear, which matters if you’re thinking of an insurance claim. The report says what was seen and what it points to. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
Where we cannot see part of the leaking roof, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

The survey, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Burnham Green can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Before the survey
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
- Check we can get to the back of the property
Book a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or send us an email when you’re ready.

Questions from Burnham Green
Is Burnham Green in the area you cover?
Yes, Burnham Green is one of the places we work. The survey and report are the same in Burnham Green as anywhere else.
How do I find out if my home in Burnham Green is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, not to carry out the repair. The report gives any roofer a clear brief.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance.
Signs you need a roof leak investigation in Burnham Green
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. Leaks from valleys often show up some distance away inside.
Problems we come across frequently include:
- Leaks below a flat extension roof
- Water coming in around a roof light or dormer
- Drips in the loft during heavy rain
- Staining where a gutter or parapet meets the wall
If you look after a shop, office or commercial unit, for instance near Howard Centre, finding where water is getting in quickly keeps disruption down.

How the survey changes by roof type
Valleys
Leaves and moss build up in valleys and hold water back. In heavy rain, it can spill under the edges of the slates or tiles.
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, letting rain run behind the joint.
Why act early in Burnham Green
A leak that returns after a repair usually means the real source wasn’t found. A careful investigation looks at every likely route, not just the obvious one. That is often what breaks the cycle. Around Burnham Green, older homes frequently have old roof timbers, and water through a failed covering can rot timber if it is left.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.

Roof leak investigations in Burnham Green: local notes
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Each of these roof types has its own typical places for water to get in. With Digswell House about 1.9 miles south-west, Burnham Green sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you let a flat or house near Welwyn North station, tracing a leak quickly matters when a tenant is living with it. Take a building like Monk's Walk School: tracing a leak on a big roof starts with where the water appears and works back.
