Electronic leak detection for homes and businesses in Tower Hill
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. Typical surveys look at damage from equipment installers and new membranes needing a check before handover, across roof terraces and balconies, commercial flat roofs and single-ply roofs.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Tower Hill, the roof above may belong to the building rather than one flat.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Tower Hill questions
Do you cover commercial flat roofs around Tower Hill?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building.
Is my home in Tower Hill listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How long will testing take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Do you use drones?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Is Tower Hill in your area?
Yes. We survey roofs in Tower Hill and the rest of Greater London. To book, ring 07833 053749 or email us.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and the South East.
What’s the best way to book?
To book, call 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. Surveys in Tower Hill can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Before we arrive
- Clear the way to the loft hatch
- Leave side gates unlocked
- Tell us where we can park nearby
Getting a price

Why it is worth a survey now in Tower Hill
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. In Tower Hill, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.

Electronic leak detection around Tower Hill
Tower Hill has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For an older house near a landmark such as Church of St Peter ad Vincula, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. For hotels and guest houses around Tower Hill, a roof problem found early is far less disruptive than one found by a guest.

Honest limits

- Parts of the roof covered by fixed equipment
- The extent of water in the insulation
- Water entering through details rather than the membrane

When to book a survey in Tower Hill
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
Signs worth acting on include:
- Waterproofing to test before it’s covered
- Holes left by work on the roof
- Leaking laps in the waterproofing
- Leaks under green or ballasted roofs
If you look after a building like The Aldgate School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
