How electronic leak detection works in Redbridge
There are different ELD methods. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we will use. If neither method suits your roof, we will tell you at the outset. If you’ve noticed damage from equipment installers and breaches around outlets and penetrations, we can find out what’s behind it, on liquid-applied waterproofing, single-ply roofs and roof terraces and balconies alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Redbridge, the roof above may belong to the building rather than one flat.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Flat roofs in Redbridge
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Valentines Mansion, about 0.7 miles south-east, is one of the historic houses in the wider area around Redbridge. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you run a business near Stratford Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. For landlords with property near Ilford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

How it works
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Redbridge runs like any other.
- 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.
- You receive the results to pass to your roofer.

Advice
Questions from Redbridge
How do I find out if my home in Redbridge is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Do you look at commercial flat roofs near Redbridge, such as hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance.
What if it rains on the day?
Light rain does not typically stop a survey, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Do you take photos of the roof?
Yes, plenty. Pictures sit next to the findings they show.
Do you use drones?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules. We are a CAA-registered drone operator.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
When you need someone else
Every survey has limits, and it’s better to know them up front. Bear these in mind:
- Leaks from plumbing or windows
- Repairing the breaches (that is for your roofer)
- Build-ups without a suitable layer below

What else we do in Redbridge
How we price electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- The number of roofs, including extensions and garages
- Features like valleys, chimneys, dormers and parapets
- The use of thermal imaging or a drone
- 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’ll know the price for the job before booking.
What to let us know when you contact us
Before you get in touch, it’s useful to have:
- Where any leaks, stains or damp patches show inside
- Anything about access we should know
- The kind of building and roof involved
- What’s prompted the survey
We survey roofs on weekdays and at weekends. To arrange a day that suits you, call 07833 053749 or send us an email with the address and the days you’d prefer.
Common roof problems in Redbridge
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak long before anyone notices.
Here are some of the things we see often:
- Damp inside with no sign on the roof
- Patched roofs that still leak
- Water coming in under a flat roof
- Breaches hidden under paving or planting
Hotels and guest houses near Redbridge can’t easily close rooms for a leak.
Before you book anyone
- Whether they hold professional indemnity and public liability insurance
- Which limits apply to the survey
- How they plan to inspect the roof safely
- Whether the inside of the roof is included
Checking the roof from ground level
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
Leave it or get it looked at?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. 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.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
