Roof leak investigation in Hogpits Bottom
We use moisture detection and thermal imaging where they help. 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. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. Typical surveys look at water coming in around a roof light or dormer and water through the ceiling under a flat roof, across rooflights and dormers, valleys and parapet gutters and the roof space.
Roofs in small places like Hogpits Bottom frequently 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 record with photos is useful if you need to show the damage to anyone else.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Practical tips
From years of surveys, a few habits stand out as worth the effort:
- Put a bucket under the drip and move valuables
- Mention earlier attempts to fix the leak
- Write down the wind direction and rain when it leaks
- Take dated photos of the leak
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.
Keep gutters, valleys and outlets clear, especially in autumn. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
Leave it or get it looked at?
Wet insulation doesn’t insulate well. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. Where a roof is exposed, as many are in small places like Hogpits Bottom, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Roof leak investigations around Hogpits Bottom
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. The covering and its details give the first clues when tracing where water is coming from. The wider area around Hogpits Bottom has a long history of building, with Chenies Manor House about 2 miles south. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you live in an older home near Church of St Mary Magdalene (Church of England), the leak may come from a chimney, a valley or tired lead rather than the covering itself.
Hogpits Bottom is about 4 miles east of Chesham, in Hertfordshire. We cover Hogpits Bottom and the rest of Hertfordshire, as part of our work across London and the South East. Hogpits Bottom is one of the places in Hertfordshire where we work for roof leak investigations. London is in our area too.
Surveys in HP3 are booked the same way as anywhere else.

Close by, we survey roofs in Bulstrode (1 mile north-east), Tower Hill (1 mile north-east), Bovingdon (1 mile north), Ley Hill (2 miles west) and Botley (2 miles west).

Questions from Hogpits Bottom
Is Hogpits Bottom in the area you cover?
Yes. We cover the whole of London and South East England, and Hogpits Bottom is part of that. Just call 07833 053749 or send us an email and let us know about the property.
How do I find out if my home in Hogpits Bottom is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is it a structural engineer’s report?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and don’t carry out calculations. If we think you need an engineer, the report says so.
How long does the visit take?
It normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
Do you use thermal imaging to find leaks?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
When you need someone else
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- Faults hidden behind ceilings or boarding
- An intermittent leak that shows no trace on the day
- Leaks from plumbing, tanks or pipework rather than the roof
If in doubt, call 07833 053749 or send us an email and we will point you to the right survey before booking. What our survey covers.
Roof types and parts we check

- Chimney stacks
- Lead flashings

What we’re asked to look at in Hogpits Bottom
Blocked gutters can look like a roof leak. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
Most people get in touch after spotting something like this:
- Water marks that spread in wet weather
- Leaks below a flat extension roof
- Damp on a chimney breast
- Water that shows only in certain storms
Landlords with a home close to Chalfont & Latimer station may find that tracing a leak quickly matters when a tenant is living with it.

What else we do in Hogpits Bottom
The survey, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and record our findings for the written report. It normally takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Older roofs in small places like Hogpits Bottom can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it is safe.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
Preparing for the visit
- For a flat or shared roof, check access with the freeholder or managing agent
- Make sure pets are kept safely away
- Make a note of anything you’d like us to look at

Roof by roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. We check outlets and the covering around them.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
