How a roof leak investigation works in St Leonards
Some ‘leaks’ are not leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, leaving marks that look just like rainwater. Knowing which it is means the right fix can be done, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. If you’ve noticed damp underlay across a wide area and staining where a gutter or parapet meets the wall, a survey will tell you what’s going on, whatever the roof.
In a village or hamlet like St Leonards, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. We look at what can safely be seen and set out what we find. Older walls and timbers hold water for a long time, so it is worth finding the cause soon.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

Your questions about roof leak investigations in St Leonards
Is my home in St Leonards listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you carry out roof surveys in St Leonards?
Yes, St Leonards is one of the places we work. Every survey there gets the same written report with photographs.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it’s useful, and it is included in our Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
What should I do before you arrive?
Clear the loft hatch so we can get into the loft space. Have any photos of the leak ready, plus details of past repairs. Keep catching drips and keep water away from electrics.
Will I get photos?
Yes. The report includes photos of what we found.
How do you tell a leak from condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern, take moisture readings and tell you which is more likely.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
What we can’t see
It helps to know what a survey won’t do before you book:
- A promise to find every leak on a single visit
- A structural engineer’s report
- Defects hidden under coverings or inside walls without opening up
If you are not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer. The full list of what we check.

What a roof leak investigation looks like in St Leonards
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Knowing the roof type helps narrow down where water may be getting in. Historic houses such as Cholesbury Manor House, about 1.1 miles east, show how far back building in the area around St Leonards goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Wendover station, a clear finding on where water gets in helps you brief a roofer straight away.

- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.

How to prepare
- Have any questions written down, so nothing gets missed
- If you’re buying, check with the agent that we can get in
- Find any records of previous roof work

Common roof problems in St Leonards
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. On slate roofs, slipping is often caused by corroded nails.
People usually book a survey after spotting something like this:
- Water coming in around a roof light or dormer
- Brown rings on upstairs ceilings
- Water through the ceiling under a flat roof
- Drips in the loft during heavy rain
If your home is one of the older ones in the streets near Church of St Leonard, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Choosing a roof surveyor
- What the survey will not cover
- Whether the loft is part of the inspection
- What follow-up you get after the report
- What exactly goes into their report
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.

Tips that help
Most of what helps is simple and safe from the ground. Our suggestions:
- Tell us about any past repairs to the roof
- Leave roof access to professionals
- Don’t touch fittings that water is reaching
- Mention any plumbing above the damp area
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
Keep the loft space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Make sure insulation does not block airflow at the eaves.
