Dial Post Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes in Dial Post, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Leaks through a covered membrane
- Leaks through a flat roof with no obvious cause

Electronic leak detection for homes and businesses in Dial Post
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. We will tell you if we think the leak is coming from somewhere else. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. We survey flat roof membranes, green roofs and single-ply roofs, and people most frequently book us about stains far from any visible defect and waterproofing to test before it’s covered.
Some older homes in villages like Dial Post are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

How the survey changes by roof type
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Bituminous membranes
Older felt roofs often have seams and patches that can leak. Testing depends on the roof.
How the survey works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. You are welcome to ask questions while we are there. For a village or hamlet like Dial Post, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare
- Gather any invoices or paperwork from past roof work
- Keep pets in another room
- Point out any leaks or damp patches

Advice
FAQs for Dial Post
Does a conservation area affect roof work in Dial Post?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Dial Post?
Yes, Dial Post is within the area we cover. We survey roofs across London and the South East. Just ring 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Does the report include photographs?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime. Let us know your preferred days as you book.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed as you book.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report. If we see signs that need an engineer’s opinion, we will recommend one.
What if it rains on the day?
Light rain doesn’t usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather is not suitable.

What we’re asked to look at in Dial Post
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
A survey makes sense if you’ve noticed:
- Failed seams and laps
- Damage from equipment installers
- Leaks showing away from the breach
- Breaches around outlets and penetrations
Around Dial Post, as everywhere, small roof faults are simplest to sort before they let water in.
Questions to ask before you book
- Is there a chance to talk the report through?
- Which parts of the roof they’ll actually see
- What exactly goes into their report
- Will they check the loft as well as the outside?
DIY checks: what’s safe
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking, as it helps us focus the survey.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.

Flat and commercial roofs around Dial Post
In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. England has around 10,000 conservation areas and about 500,000 listed buildings. If your 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, so the council is the place to ask.
For properties in and around Dial Post, we check what can be seen safely and explain what we find.
