How electronic leak detection works in Bromley
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. It is testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. Common reasons to book are new roofs to check before paving or planting and breaches hidden under paving or planting, across flat roof membranes, commercial flat roofs and roof terraces and balconies.
Some older homes in villages like Bromley are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

What electronic leak detection looks like in Bromley
The wider area around Bromley has a long history of building, with Much Hadham Palace about 1.4 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Landlords with a home close to Bishops Stortford station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Bromley: your questions answered
Is my home in Bromley listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Bromley in the area you cover?
Yes. We cover the whole of London and South East England, and Bromley is part of that. You can phone 07833 053749 or use the contact form with the address and a few details.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we are not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
Do you survey on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days as you book.
Does electronic leak detection work on all membranes?
That depends on the roof’s membrane and layers. Share any details you have and we will confirm suitability.
Prices for electronic leak detection in Bromley
When we price a survey, we consider:
- The use of thermal imaging or a drone
- The number of roofs, including extensions and garages
- Commercial roofs and larger buildings
- Building height and the viewpoints available
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before booking.
Helping us price your survey
The more you tell us, the easier it is to price the survey. When you contact us, let us know:
- Pictures of the roof from a safe spot, if you have them
- Any marks or damp showing indoors
- Where the property is, with the postcode
- The reason for the survey, such as buying, a leak or storm damage

Landlords, agents and block managers in Bromley
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we will plan the survey around it.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
What happens on the day
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes a time that depends on the roof’s area and construction, which we set out in the quote. Rural addresses near Bromley can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Show us where any leaks or stains appear
- Let us know about parking before the day
- Move anything stored under the loft hatch
Getting a price
We confirm the price for your roof before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or email us.

EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes frequently appear.
What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. For an older or listed building in a place like Bromley, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
