About our roof leak investigation in Upper North Dean
Moisture readings and thermal imaging are used where they’re useful. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. Typical surveys look at drips from nail tips in a cold loft and water marks that spread in wet weather, on rooflights and dormers, slate and tile slopes and valleys and parapet gutters.
Roofs in small places like Upper North Dean often stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
Findings are set out part by part, from the main slopes down to the gutters and outlets. You will see the good as well as the bad.

Upper North Dean questions
Is Upper North Dean within the area you cover?
We do. A small place gets exactly the same survey as a big one.
Do you carry out roof surveys in Upper North Dean?
We do. Every survey there gets the same written report with photos.
Can thermal imaging help find my roof leak?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
Does the investigation include the repair?
A leak investigation finds and reports the likely source. The repair itself is a separate job. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
How do you tell a leak from condensation?
The two can look alike. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern of damp and the ventilation, then say which is most likely.
How quickly is the report sent?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.

How the survey changes by roof type
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Chimney stacks
We look at the outside of the stack and the breast inside, and it is not a flue or gas safety check.
The survey, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take roughly 1–2 hours at most homes, or half a day or so for a commercial building. Older roofs in small places like Upper North Dean can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start with your notes and photos of the leak.
- Inside, we look at the stain and the ceiling around it.
- From the roof space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Make sure pets are kept safely away
- Have any questions written down, so nothing gets missed
- Let us know about parking near the property

Related advice
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
What a roof leak investigation doesn’t cover
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Plumbing leaks that look like roof leaks
- An intermittent leak that shows no trace on the day
- Whether rotten timbers meet design loads
If you are not sure which survey you need, call 07833 053749 or send us an email and we’ll give you a straight answer before you book. What a survey covers and does not.
What we look at
- Flat roof details
- Slate and tile slopes
- Valleys and parapet gutters
- Lead flashings
- The roof space
- Chimney stacks
- Rooflights and dormers
Leave it or get it looked at?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. Around Upper North Dean, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400. We confirm the exact price before booking.

Roof leak investigations around Upper North Dean
About 2.4 miles south lies Hughenden Manor, a reminder of how long the area around Upper North Dean has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Thatch survives on some older buildings in Buckinghamshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Each of these roof types has its own typical places for water to get in.
For site and facilities teams at buildings such as Speen CofE VA School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. Shop and office owners around Eden may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
