A stack has several possible ways in for rain. Each is checked from every safe vantage point.
Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
Roof leak investigation in Thornborough
Our roof leak investigations cover Thornborough and the wider South East. We visit on any day of the week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. You get a report with photos and recommendations. If it is leaking right now, contain the water and keep it clear of electrics, and then call 07833 053749 or email us. We survey flat roof details, valleys and parapet gutters and lead flashings, and the problems we’re asked to look at most are staining where a gutter or parapet meets the wall and condensation that looks like a leak.
Being in a small place like Thornborough makes no difference to how a leak or storm damage is looked at: the journey and access are just planned beforehand. Let us know where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

What we are asked to look at in Thornborough
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
Problems we come across frequently include:
- Water dripping from rafters or underlay
- Ceiling stains that grow after rain
- Water through the ceiling under a flat roof
- Damp underlay across a wide area
Take an older house close to Church of St Mary: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Questions to ask before booking
- What experience they bring
- Which viewpoints they use to see the roof
- Whether VAT is added on top
- Will the report include photos?
What a roof leak investigation does not cover
Some things cannot be seen without opening up the roof, and that sets some limits:
- The repair itself (the investigation finds and reports the cause)
- Whether rotten timbers meet design loads
- Leaks from plumbing, tanks or pipework rather than the roof
If in doubt, call 07833 053749 or email us and we’ll suggest the right survey. What our survey covers.

Practical tips
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Do not climb onto the roof to look
- Keep a photo record of the damp patch
- Catch drips in a bucket and protect the floor
- Write down the wind direction and rain when it leaks
Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found.
Keep the roof space ventilated. Good airflow reduces condensation, which is often mistaken for a leak. Keep insulation clear of the eaves.
Your questions about roof leak investigations in Thornborough
Is Thornborough within the area you cover?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Thornborough is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you definitely find the leak?
Not always, and we’ll be honest about that. Some leaks hide well, especially those that need wind-driven rain. Where the source isn’t certain, we list the likely routes in order.
How long does a roof leak investigation take?
The visit usually takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. We’ll confirm what to expect when we arrange the visit.
Do you climb onto every roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.

What else we do in Thornborough
Leaks and storm damage in Thornborough
About 4.9 miles north-west lies Stowe House, a reminder of how long the area around Thornborough has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Thatch survives on some older buildings in Buckinghamshire’s villages. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. The covering and its details give the first clues when tracing where water is coming from.
If you look after a building such as Thornborough Infant School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Prices for roof leak investigations in Thornborough
Survey packages start from £150, inc. VAT. The price for your roof depends on:
- Basic, Standard or Premium
- The number of roofs, including extensions and garages
- Commercial roofs and larger buildings
- How tall the building is and how easy the roof is to see
Our price is from £150, including VAT. The final price depends on how big and how high the roof is, how it can be seen safely and which survey you book.
What to let us know when you get in touch
Getting the details right at the start saves time. It helps to include:
- Whether there’s a loft hatch, a shared roof or tricky access
- Any deadline, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- Why you want a survey: buying, a leak, a storm or new work
Most bookings start with a short call: phone 07833 053749 or send us an email, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.
What we do, step by step
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes between one and two hours at most homes, and longer for a large or complex roof. You are welcome to ask questions while we are there. Older rural homes like those around Thornborough can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Jot down any questions you want answered
- Tell us about parking before the day
- Leave a clear route to the loft
