Electronic leak detection in Mayes Green: what you get
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 knows exactly where to repair. The results come in a report with photos. If you’re worried about leaks showing away from the breach and failed seams and laps, a survey will tell you what’s going on, on commercial flat roofs, roof terraces and balconies and single-ply roofs alike.
In a small place like Mayes Green, a flat roof can stand in the open, 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.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

How it works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take as long as needed for the size of the roof and how it’s built, which we set out in the quote. Around Mayes Green, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go 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.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- For a flat or shared roof, check access with the building owner or managing agent
- Note where any stains or damp appear
- Leave a clear route to the loft
Book a survey
Every survey is priced before it is booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or send us an email.

Electronic leak detection in Mayes Green: local notes
An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Landlords with a home close to Ockley station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Mayes Green is about 6 miles north-west of Horsham, in Surrey. In Mayes Green, as across Surrey, every roof gets the same careful survey. Across Surrey, we cover Mayes Green and the places around it. Our Crawley page covers surveys nearby.

What a survey costs
Several things affect the price of a survey:
- The number of roofs, including extensions and garages
- If the survey needs thermal imaging or a drone
- The roof’s overall size
- Features like valleys, chimneys, dormers and parapets
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
Helping us price your survey
If you can, have these to hand when you contact us:
- Pictures from the garden or a window, if you have them
- What’s prompted the survey
- The property’s address and postcode
- Any deadline, like an exchange date
To book a survey, phone 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
Checking the roof from ground level
A DIY look is useful, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
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.
What this survey cannot tell you
It is a careful look at the flat roof membrane, not the whole story. Its limits include:
- Sections we cannot safely access
- Moisture spread under the membrane
- Leaks from walls, copings or rooflights
If you are not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer. The full list of what we check.

Your questions about electronic leak detection in Mayes Green
Does a conservation area affect roof work in Mayes Green?
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.
Is Mayes Green within the area you cover?
Yes, Mayes Green is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Will you fly a drone over my roof?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Do you look in the roof space?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and call 07833 053749 or use the contact form for a quote.
How long have you been surveying roofs?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather isn’t right.
Useful tips for Mayes Green property owners
Nothing here needs a ladder. A few suggestions:
- Avoid repeated repairs without finding the cause
- Do not leave water getting in
- Limit access to the roof
- Ask contractors to protect the membrane
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Signs you need electronic leak detection in Mayes Green
When the membrane is buried, holes cannot be seen at all. ELD can work on some covered roofs, depending on the build-up.
We are often asked to look at:
- Holes left by work on the roof
- Repairs that haven’t stopped the leak
- Water coming in under a flat roof
- Waterproofing to test before it is covered
If you live in an older home near Church of St John the Baptist, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Questions to ask before you book
- What’s outside the scope of the survey
- Whether the loft space is looked at, where there is one
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- How long the report takes to arrive
