Electronic leak detection in Sunningdale
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. It’s testing only and leave the repair to your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We are often asked to look into new roofs to check before paving or planting and leaks through a flat roof with no obvious cause, on flat roof membranes, liquid-applied waterproofing and green roofs.
In a smaller place like Sunningdale, some flat roofs sit in the open, where wind can catch 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 is written in plain words, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Roof by roof
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We will tell you if yours isn’t suitable.
What happens on the day
Photographs are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a survey in Sunningdale, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- You tell us about the roof and where water is showing.
- 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.
- You get a report with photos of each breach.
Before we arrive
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work
- For a flat or shared roof, check access with the building owner or managing agent

Do you need electronic leak detection in Sunningdale?
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in long before anyone notices.
Most people get in touch when they’ve noticed one of these:
- Damage from equipment installers
- New roofs to check before paving or planting
- Stains far from any visible defect
- Repairs that haven’t stopped the leak
If you live in an older home near Holy Trinity Church, 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 booking
- How long they’ve been surveying roofs
- What follow-up you get after the report
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How they plan to inspect the roof safely

Flat roofs in Sunningdale
Historic houses like St Leonard's Hill, about 4.8 miles north, show how far back building in the area around Sunningdale goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you let a flat or house near Sunningdale station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Holy Trinity CofE Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Your questions about electronic leak detection in Sunningdale
Does a conservation area affect roof work in Sunningdale?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Is Sunningdale in the area you cover?
Yes, Sunningdale is within the area we cover. We work right across London and South East England. You can call 07833 053749 or send us an email with the address and some details.
Can you tell me if my roof has asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
What insurance do you have?
We are covered by professional indemnity and public liability insurance.
Is this a RICS survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Does ELD include fixing the breach?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Practical tips
A survey works best with a little help from you, before and after. Tips:
- Share any drawings of the roof
- Find the breach before more patching
- Check new waterproofing before handover
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Why it is worth a survey now in Sunningdale
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Tradespeople may need to travel further to a smaller place like Sunningdale, so it helps to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
