Electronic leak detection in Aldwych
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you’re worried about damage from equipment installers and water coming in under a flat roof, a survey will tell you what’s going on, on single-ply roofs, flat roof membranes and green roofs alike.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Aldwych shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
After the visit, you get a report with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Why get it checked now?
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Blocked gutters and hoppers on London houses overflow and soak brickwork. A blocked outlet ignored for a winter or two can mean damp walls inside.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Surveys for landlords and agents in Aldwych
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
When to book a survey in Aldwych
Holes in a membrane frequently come from feet, tools or debris. Many are tiny but water still finds them.
Here are some of the things we see often:
- Waterproofing to test before it is covered
- Patched roofs that still leak
- Damp inside with no sign on the roof
- Holes left by work on the roof
Take an older house close to St Mary le Strand: the flat roofs on later extensions tend to wear out long before the main roof.
Before you book anyone
- Their drone registration, if they fly one
- What experience they bring
- What’s outside the scope of the survey
- How they’ll see the roof: from ground level, the loft, the roof or by drone
What happens on the day
Safety comes first on every visit. We inspect everything that’s safely in view, and if part of the roof can’t be seen, the report says so. The survey typically takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Aldwych runs like any other.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- If you’re buying, check with the agent that we can get in
- Check the loft hatch can be reached
Getting a price

Related advice
Before and after the survey
Some practical points come up on survey after survey. They apply to most roofs:
- Keep foot traffic on flat roofs to a minimum
- Get leaks traced quickly
- Consider ELD before paving or planting goes on
- Find the breach before more patching
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
Electronic leak detection around Aldwych
Aldwych has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use. With Dr Johnson's House about 0.4 miles east, Aldwych sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near London Charing Cross station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you run a hotel or guest house in or near Aldwych, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition.

Aldwych questions
Do you look at commercial flat roofs near Aldwych, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Can parking be tricky for a visit in Aldwych?
It depends on the street. If Aldwych has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
What’s in the survey report?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely.
How do I arrange electronic leak detection in Aldwych?
It’s easiest to ring 07833 053749 or send us an email. Let us know the address and a little about the roof, and we will suggest the right survey. Surveys run on weekdays, Saturdays and Sundays.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, so wherever there’s a hole, it passes through. That lets us find breaches that are too small to see.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
How soon will I get the report?
Report times are set by the package. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know when booking.
