How electronic leak detection works in Lewes
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We’re often asked to look into leaks through a covered membrane and waterproofing to test before it’s covered, on roof terraces and balconies, green roofs and flat roof membranes.
In a town like Lewes, lots of shops, schools and business units have flat roofs. Out of sight, they tend to be forgotten until a leak appears. A survey, or electronic testing where the membrane suits it, shows what’s going on. If someone else manages the building, let us know so roof access can be arranged.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Common roof problems in Lewes
Holes in a membrane frequently come from feet, tools or debris. Some are too small to see but water still finds them.
Look out for signs like these:
- Punctures from foot traffic or tools
- Patched roofs that still leak
- Damp inside with no sign on the roof
- Leaks through a covered membrane
If you own a rental within reach of Lewes station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Questions to ask before booking
- Whether the roof space is looked at, where there is one
- Whether you get a written report with photos
- Their drone registration, if they fly one
- What they won’t be able to tell you
What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- Whether it is a home or a commercial building
- Height and safe access
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
To find out what your survey will cost, ring 07833 053749 or send us an email and let us know about the roof. We will confirm the figure before booking.
Booking your survey
We’ll normally ask about:
- Your timetable, like an exchange date
- What made you get in touch
- How the loft is reached, if there is one
- Photos of the roof, taken safely from ground level or a window
Every survey is priced before it’s booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or send us an email.
For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Let us know about it as you book and we will plan the visit with that in mind.
We survey roofs for landlords and letting agents as well as homeowners. The report gives you a dated record of the flat roof membrane, with photos.
Lewes: your questions answered
Is Lewes in the area you cover?
Yes. We work right across London and South East England, and Lewes is part of that. Just phone 07833 053749 or drop us an email and tell us about the property, and we’ll talk through which survey suits.
How do I find out if my home in Lewes is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
How do I arrange electronic leak detection in Lewes?
Just phone 07833 053749 or drop us an email. We’ll ask a few questions, confirm the price and agree a date.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. We will explain why when we quote.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just call 07833 053749 or drop us an email for a quote.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Electronic leak detection in Lewes: local notes
About 0.6 miles south lies Anne of Cleves House, a reminder of how long the area around Lewes has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. There are several hotels within about a mile and a half of Lewes, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
The streets around a church such as Church of St John sub Castro are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking. For hotels and guest houses around Lewes, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

How the survey works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. You are welcome to ask questions while we are there. Most visits in a town like Lewes start at the front of the house and work round to the back. Rear gardens and side paths frequently give the best view of extensions and back slopes. The loft comes next, where there is safe access.

DIY checks: what’s safe
It’s useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
Look up at the roof after a storm, from ground level: 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.
What we look for on each type of roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
