About our electronic leak detection in Tower Hill
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. We survey roof terraces and balconies, commercial flat roofs and flat roof membranes, and the problems we are asked to look at most are new roofs to check before paving or planting and repairs that haven’t stopped the leak.
Some older homes in villages like Tower Hill are listed or in a conservation area, which can shape what a new flat roof may look like. 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. Listed building consent is needed for changes that affect a listed building’s special interest.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Why it’s worth a survey now in Tower Hill
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Where a roof is exposed, as many are in small places like Tower Hill, driving rain gets into any weakness, and damp in older walls is slow to dry out.
To find out what your survey will cost, phone 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

Do you need electronic leak detection in Tower Hill?
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems such as:
- Damage from equipment installers
- Leaks that return after repairs
- Water coming in under a flat roof
- Stains far from any visible defect
Anyone responsible for a site like St John's Catholic Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Choosing a roof surveyor
- What follow-up you get after the report
- Which limits apply to the survey
- Their drone registration, if they fly one
- Whether the inside of the roof is included
What we do, step by step
The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Tower Hill can have low, tight loft spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Jot down any questions you want answered
- Unlock side gates and any roof access doors
- If you are buying, check with the agent that we can get in

Tower Hill: your questions answered
Is my home in Tower Hill listed or in a conservation area?
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.
Will you come out to Tower Hill?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route as you book.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
Will you photograph what you find?
Yes. Photos are part of every report, so you can see each point for yourself.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof. Just call 07833 053749 or use the contact form for a quote.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Roof by roof
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Checking the roof from ground level
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Local flat roofs in Tower Hill
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. Many older homes in Sussex have handmade clay tiles and tile-hung walls. Horsham stone slab roofs survive on some old Sussex buildings. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Christs Hospital station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take an older house close to Parish Church of St Mary: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
