Electronic leak detection in Patching: local notes
Hylands, about 3 miles south-west, is one of the historic houses in the wider area around Patching. On older houses around here, roofs frequently 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. Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a shop, office or commercial unit, for example near Bond Street Chelmsford, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you look after a building such as St John Payne Catholic School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Electronic leak detection for homes and businesses in Patching
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you’re worried about leaks through a covered membrane and patched roofs that still leak, we can find out what’s behind it.
Flat roofs in smaller places like Patching can be more exposed, particularly where nothing shelters them, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You will see the good as well as the bad.

Your questions about electronic leak detection in Patching
How do I find out if my home in Patching is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Patching in the area you cover?
Yes. We survey roofs across London and the South East, and Patching is part of that. You can call 07833 053749 or use the contact form with the address and a few details.
Do you use drones?
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 every flight depends on the airspace and the weather.
How is ELD priced?
We quote for each roof individually. Send us details of the roof. Just phone 07833 053749 or email us for a quote.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We can only inspect what we’re given access to.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. We’ll explain why when we quote.
Roof by roof
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll say if the test won’t work.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Prices for electronic leak detection in Patching
All our prices include VAT. What changes the price is:
- If the survey needs thermal imaging or a drone
- Chimneys, valleys, parapets and other details
- How many separate roofs there are, such as extensions, dormers and garages
- The size of the roof
To find out what your survey will cost, ring 07833 053749 or email us with the address and some details. The price is agreed before a date is set.
Getting in touch
There is no need for technical words. Just tell us:
- Your timetable, such as an exchange date
- What kind of property and roof it is
- Where water is showing inside, if it is
- Any photos you have, taken from ground level or a window
To arrange a survey, call 07833 053749 or send us an email and let us know the address and what’s prompted the survey. We will confirm the price before booking.
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays and at weekends, which can make access easier.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
How it works
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes as long as needed for the membrane area and the build-up, which we set out in the quote. For a survey in Patching, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. Tell us about any garages, outbuildings or extensions you want included.
- 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.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Make a note of anything you’d like us to look at
- If you’re buying, let the agent know when we’re coming
- Move anything stored under the loft hatch
Book a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please do not climb up for a closer look. To send them or to book, ring 07833 053749 or email us.

Other services in Patching
Should I look at the roof myself first?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
