About our electronic leak detection in Upton
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. Common reasons to book are leaks showing away from the breach and holes left by work on the roof, across roof terraces and balconies, single-ply roofs and flat roof membranes.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Upton, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Different roofs, different checks
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers, depending on the build-up.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
How the survey works
We don’t take risks to get a closer look. 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 longer on a large roof than a small one, and the build-up of the roof makes a difference too. Surveys in Upton can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- 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.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- For a flat or shared roof, check access with the freeholder or managing agent
- Have any questions written down, so nothing gets missed
- Unlock side gates and any roof access doors

If you are buying, it’s useful to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.

Common questions in Upton
Will parking be an issue for a roof survey in Upton?
Sometimes, yes. If Upton has controlled parking where you are, a visitor permit is the easiest answer.
Do you carry out roof surveys in Upton?
Yes. We survey roofs across London and South East England, and Upton is part of that. You can call 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
How is ELD priced?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, call 07833 053749 or use the contact form.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather isn’t right.
Does ELD work under paving or planting?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We’ll discuss it before we quote.
Why get it checked now?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. London’s older roofs frequently have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for your roof before booking.

Do you need electronic leak detection in Upton?
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Here are some of the things we see often:
- Breaches hidden under paving or planting
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
- Repairs that haven’t stopped the leak
For an older house near a landmark such as St Peter's Church, the joins between later flat roofs and the old walls are where problems normally start.
Choosing a roof surveyor
- Whether the loft space is looked at, where there is one
- How much experience they have with roofs like yours
- Whether the price includes VAT
- Are they insured for the work?
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Ask contractors to protect the membrane
- Test new membranes before covering them
- Record dates and spots where water appears
- Keep outlets clear of debris
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Flat roofs in Upton
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. The wider area around Upton has a long history of building, with Valentines Mansion about 2.8 miles north-east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If you own a rental within reach of Forest Gate station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings like Elmhurst Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
