Electronic leak detection for homes and businesses in Watt's Cross
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small 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 knows exactly where to repair. You get a report with photographs of each breach found. We survey green roofs, commercial flat roofs and single-ply roofs, and common reasons people get in touch are new membranes needing a check before handover and damage from equipment installers.
Flat roofs on exposed homes in small places like Watt's Cross take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Nothing in the report is left vague: where something needs attention, it says so plainly, and where it can wait, that is said too.

Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
Do you need electronic leak detection in Watt's Cross?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Some are too small to see but water still finds them.
It is worth booking a survey if you’ve seen:
- Repairs that haven’t stopped the leak
- Leaks under green or ballasted roofs
- New membranes needing a check before handover
- Punctures from foot traffic or tools
For landlords with property near Hildenborough station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Questions to ask before booking
- What exactly goes into their report
- What insurance they carry
- Their report turnaround times
- Whether the roof space is looked at, where there is one
Watt's Cross: your questions answered
Do you carry out roof surveys in Watt's Cross?
Yes, Watt's Cross is within the area we cover. Our area covers London and South East England. Just call 07833 053749 or email us and let us know about the property, and we will talk through which survey suits.
Does a conservation area affect roof work in Watt's Cross?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Share any details you have and we will confirm suitability.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
Will I get photos?
Yes. The report includes photographs of what we found, so you can see exactly what each finding refers to.
Which method do you use?
We choose the method that suits the roof. You’ll know which method we plan to use before we start.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Why get it checked now?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye, on suitable membranes. For an older or listed building in a place like Watt's Cross, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
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 your roof before you book.

Electronic leak detection around Watt's Cross
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Historic houses like Ightham Mote, about 3 miles north-east, show how far back building in the area around Watt's Cross goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
For an older house near a landmark like Parish Church of St John, the joins between later flat roofs and the old walls are where problems typically start. For site and facilities teams at buildings such as Hildenborough Church of England Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

How the survey works
After the inspection, everything we found is written up as a photo-illustrated written report, emailed to you. As for time on site, it typically 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. In a hamlet or village like Watt's Cross, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Keep pets inside or away from the areas we’re looking at
- Tell us about parking before the day
