What electronic leak detection looks like in Leyton
There are several hotels within about a mile and a half of Leyton. 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, often with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Leyton is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your house is among the older ones in the streets near Christian Hope Ministries International, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For hotels and guest houses around Leyton, a roof problem found early is far less disruptive than one found by a guest. Historic houses such as Sutton House, about 2.2 miles south-west, show how far back building around Leyton goes. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.

Electronic leak detection for homes and businesses in Leyton
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at 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 holes around roof penetrations and punctures from foot traffic or tools, across single-ply roofs, liquid-applied waterproofing and green roofs.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Leyton shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

How we price electronic leak detection
All our prices include VAT. What changes the price is:
- The height of the building and how the roof can be seen safely
- The roof’s overall size
- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
Getting in touch
There is no need for technical words. It’s enough to let us know:
- The kind of building and roof involved
- Access details, such as a loft hatch or a shared roof
- The property’s address and postcode
- Any deadline, such as an exchange date
Most bookings start with a short call: phone 07833 053749 or send us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
The survey, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes more time on a big roof than a small one, with the construction of the roof playing a part too. For a visit in Leyton, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- 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.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Getting ready for the survey
- Let us know where we can park nearby
- If the roof is shared, arrange access with whoever manages the building
- Unlock side gates and any roof access doors
Arrange a survey
If you’re buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.

Useful tips for Leyton property owners
You do not need to be a roofer to help. What helps most:
- Limit access to the roof
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
- Have roof specifications to hand
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
What happens if roof problems are left?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
All our prices include 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 you book.
What you get with us
- Weekday and weekend surveys
- Every finding written up with photos
- Drones and thermal imaging where it applies

Leyton: your questions answered
Is parking a problem for a survey in Leyton?
Sometimes, yes. If Leyton has controlled parking where you are, a visitor permit is the easiest answer.
Does a conservation area affect roof work in Leyton?
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.
How much does electronic leak detection cost?
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. To get a quote, phone 07833 053749 or send us an email.
What if it rains on the day?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance.
What we can’t see
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- The extent of water in the insulation
- Repairing the breaches (that’s for your roofer)
- Water entering through details rather than the membrane
If in doubt, call 07833 053749 or drop us an email and we will point you to the right survey before booking. What our survey covers.
What we look at
- Commercial flat roofs
- Liquid-applied waterproofing
- Green roofs
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
Checking the roof from ground level
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
