Electronic leak detection in Chipstead: what you get
You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. We survey liquid-applied waterproofing, green roofs and commercial flat roofs, and common reasons people get in touch are leaks through a covered membrane and repairs that haven’t stopped the leak.
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 Chipstead shapes how it is checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
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.

Electronic leak detection around Chipstead
With Nonsuch Mansion about 4.5 miles north-west, Chipstead sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of 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’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For site and facilities teams at buildings like Chipstead Valley Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. Chipstead is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier.

What you can safely check yourself
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Record dates and spots where water appears
- Stay off the flat roof unless needed
- Do not let outlets block
- Let us know about the membrane and build-up if you know it
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Do not leave a flat roof leak running. Water under a membrane can spread.

How the survey works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- Move anything stored under the loft hatch
Arrange a survey

FAQs for Chipstead
Does a conservation area affect roof work in Chipstead?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Chipstead?
Yes. We work right across London and South East England, and Chipstead is part of that. You can ring 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. To get a quote, call 07833 053749 or drop us an email.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Can you survey at the weekend?
We carry out surveys seven days a week. To find a day that suits you, phone 07833 053749 or send us an email.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Signs you need electronic leak detection in Chipstead
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Typical things we are asked to look at include:
- Leaks through a covered membrane
- New roofs to check before paving or planting
- Repairs that haven’t stopped the leak
- Leaks at pipes, outlets or fixings
If you let a flat or house near Chipstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- What exactly goes into their report
- Whether the loft is part of the inspection
- Their report turnaround times
