About our roof leak investigation in Knockholt Pound
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. Common reasons to book are water through the ceiling under a flat roof and leaks at a dormer or roof window, across flat roof details, the roof space and chimney stacks.
Somewhere as small as Knockholt Pound, older roofs have frequently been repaired many times. That makes it hard to tell new damage from old wear, and the difference matters, particularly to an insurer. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Knockholt Pound roofs and the weather
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Different coverings let water in at different points, which shapes where the search starts. Historic houses such as Down House, about 3.2 miles west, show how far back building in the area around Knockholt Pound goes. 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.
Anyone responsible for a site like Halstead Community Primary School will know that a leak through a large roof is often found some distance from where the water shows inside. Living close to Polhill Bank is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall. If your home is one of the older ones in the streets near St Katharine's Church, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Knockholt Pound is about 4 miles north-west of Sevenoaks, in Kent.

What happens on the day
Every roof is different, but as a rough guide the survey takes an hour or two, more where the leak is intermittent or the roof is large. You are welcome to ask questions while we’re there. Somewhere like Knockholt Pound needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect what can safely be seen, inside and out.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the loft space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Preparing for the visit
- For flats, check roof access has been agreed
- Unlock side gates and any roof access doors
- Jot down any questions you want answered

Practical tips
A survey works best with a little help from you, before and after. Some tips:
- Record whether it leaks in every downpour or only some
- Make sure the loft is accessible
- Keep a photo record of the damp patch
- Let us know about any past repairs to the roof
The report gives whoever carries out the work a clear starting point. The photos show the defects and where they are, so the repair is aimed at the cause.
Plan a roof survey every few years. They’re where most leaks start, and catching wear early keeps water out.
Leave it or get it looked at?
Guesswork repairs are a common reason leaks keep coming back. The real way in may be a metre or more away. An investigation finds the likely cause first, so the repair is aimed at the right place. Older and listed buildings around Knockholt Pound may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.

Knockholt Pound questions
Do you cover smaller places like Knockholt Pound?
Yes, Knockholt Pound is covered. We survey roofs across London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
How do I find out if my home in Knockholt Pound is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
What does the report include?
Written findings with photographs, explaining the condition of the leaking roof, any defects and our recommendations, in order of urgency where relevant. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
What should I do before you arrive?
Keep a note of when it leaks, and take photos. Clear access to the loft. If water is near any fittings, have an electrician check them.
What do I do with the report?
You will get the report by email, with photographs and clear recommendations. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Different roofs, different checks
Valleys
Valleys collect water from two roof slopes. Worn or split linings and slipped valley tiles let it under the coverings.
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. Lifted, split or slipped lead is a common cause, and for flashings that have been patched with bitumen.
When you need someone else
To be straight with you, there are limits to any roof survey:
- Carrying out the fix
- Whether rotten timbers meet design loads
- A promise to find every leak on a single visit
If in doubt, call 07833 053749 or email us and we’ll point you to the right survey before booking. What our survey covers.
