Your questions about electronic leak detection in Single Street
Will parking be an issue for a roof survey in Single Street?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Do you cover Single Street?
Yes, Single Street is within the area we cover. Our area covers London and South East England. You can call 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Does the weather affect the survey?
It depends on the weather and the survey. In high wind or heavy rain, a drone can’t fly and access may not be safe, so we’d move the date with you.
How do you choose the testing method?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Tell us what you know about the roof and we will check whether ELD will work.
How do I arrange electronic leak detection in Single Street?
The quickest way is to call 07833 053749 or send us an email. Tell us the address and a little about the roof, and we will take it from there. Surveys run on weekdays and at weekends.
How electronic leak detection works in Single Street
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 and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. If you’ve noticed a flat roof leak that can’t be traced and stains far from any visible defect, a survey will tell you what’s going on, whatever the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Single Street, the roof above may belong to the building rather than one flat.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t.

What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
For landlords and managing agents
With a portfolio of properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or send us an email with the addresses.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
How the survey works
We check the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes a time that depends on the roof’s area and construction, which we’ll explain when we quote. Surveys in Single Street can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare

Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us with the address and the days you’d prefer.

Prices for electronic leak detection in Single Street
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- The use of thermal imaging or a drone
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages
- How complicated the roof is, with its valleys, chimneys and parapets
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.
Booking your survey
When you call or email, these details help:
- Where the property is, with the postcode
- Anything about access we should know
- The kind of building and roof involved
- The reason for the survey, like buying, a leak or storm damage
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or email us when you’re ready.
Why it’s worth a survey now in Single Street
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there is time to plan.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.

- Weekday and weekend surveys

Signs you need electronic leak detection in Single Street
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
We’re often asked to look at:
- Patched roofs that still leak
- Breaches hidden under paving or planting
- Damp inside with no sign on the roof
- Leaks through a flat roof with no obvious cause
For landlords with property near Chelsfield station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- Whether you can ask questions once you have the report

Local flat roofs in Single Street
Historic houses like Down House, about 1 mile north-west, show how far back building in the area around Single Street goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Single Street is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
The streets around a church like Church of St Peter and St Paul are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems normally start. Parking in Single Street, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.
