Electronic leak detection for homes and businesses in East Grinstead
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We survey green roofs, commercial flat roofs and flat roof membranes, and the problems we’re asked to look at most are gaps at membrane joints and leaks at pipes, outlets or fixings.
Houses around a town like East Grinstead often have a flat roof somewhere, over an extension, garage, porch or dormer. Many are felt, and newer ones may be EPDM rubber or GRP. Ponding water, splits along the edges and lifting upstands are the usual warning signs. Standing water days after rain frequently shows a flat roof needs attention.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- If the survey needs thermal imaging or a drone
- The number of roofs, including extensions and garages
- Whether it’s a home or a commercial building
- Roof area
For a price for your roof in East Grinstead, ring 07833 053749 or drop us an email with the address and some details. We’ll confirm the figure before booking.
Helping us price your survey
If you can, have these to hand when you get in touch:
- Access details, like a loft hatch or a shared roof
- Why you want a survey: buying, a leak, a storm or new work
- The style of property, from a terrace to a block
- Dates you are working to, such as exchange
If you have photos of the roof, send them over. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, ring 07833 053749 or drop us an email.

What we do, step by step
We work from the outside in: outside views come first, then the loft space if there is safe access. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. Semi-detached and terraced homes in a town like East Grinstead often share a roof line with the neighbours, so shared parts are looked at as far as they can be seen from your property. Tell us about any known leaks, past repairs or building work as you book.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Preparing for the visit
- Check pets are kept safely away
- Make sure the loft hatch can be reached
- Show us where any leaks or stains appear
Book a survey
Most bookings start with a short call: phone 07833 053749 or send us an email, and we will ask about the building and what you need. You will have a price before anything is arranged.

How the survey changes by roof type
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
Tips that help
Over many surveys, some simple habits stand out as worth the effort:
- Use boards when working on the roof
- Clear flat roof outlets regularly
- Don’t keep patching the same spot
- Note where leaks show inside and when
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Act on leaks quickly. Water under a membrane can spread.
Why act early in East Grinstead
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye where the roof suits it. On a house in a town like East Grinstead, wet loft insulation stops working and can stay damp for a long time. That is an extra cost on top of the roof work itself.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your survey before you book.

Questions from East Grinstead
Do you look at commercial flat roofs near East Grinstead, like hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building, and roof access is agreed with you before the visit.
Is East Grinstead in the area you cover?
Yes, East Grinstead is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Let us know about it as you book and we will explain what’s needed.
How does ELD work?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Does someone need to be in?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when booking.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.

Local flat roofs in East Grinstead
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With Saint Hill Manor about 1.7 miles south-west, East Grinstead 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, and the council can say whether a home is in a conservation area.
If you own a rental within reach of East Grinstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like St Mary's CofE Primary School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If your house is among the older ones in the streets near Our Lady and St Peter's Church, the flat roofs on later extensions tend to wear out long before the main roof.
