DIY checks: what’s safe
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Electronic leak detection in Grove Park
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. We test and report, and the repair is for 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. Typical surveys look at leaks showing away from the breach and patched roofs that still leak, on green roofs, commercial flat roofs and flat roof membranes.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Grove Park, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Why it’s worth a survey now in Grove Park
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What we do, step by step
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In Grove Park, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when you book.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- Dig out any old roof reports or invoices
- Keep pets out of the way during the survey
- Leave a clear route to the loft
Booking a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or email us when you’re ready.
Advice
What affects the cost of electronic leak detection
We confirm the exact price before you book. This is what makes a difference:
- If the survey needs thermal imaging or a drone
- Roof area
- Extra roofs, like extensions, dormers or garages
- Building height and the viewpoints available
To find out what your survey will cost, phone 07833 053749 or drop us an email with the address and some details. The price is agreed before a date is set.
Getting in touch
You do not need to know any roofing terms. It’s enough to tell us:
- Where any leaks, stains or damp patches show inside
- The property’s address and postcode
- Your timetable, like an exchange date
- The style of property, from a terrace to a block
Booking is simple: just phone 07833 053749 or email us, let us know about the property and we will recommend the right survey. We confirm the price before anything is booked.
Questions from Grove Park
Is my home in Grove Park listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Grove Park?
Yes. Our area covers London and South East England, and Grove Park is part of that. Just ring 07833 053749 or send us an email and let us know about the property.
What do I do with the report?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Does ELD include fixing the breach?
No. We test the membrane and report. The report shows where each breach is so your roofer can fix them.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them.
Do you climb onto every roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
What if it rains on the day?
A survey can normally go ahead in light rain. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions aren’t right we will arrange another day with you.
Other services in Grove Park
What we look for on each type of roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. ELD can locate them.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We will tell you if yours is not suitable.
Honest limits
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Carrying out the repair work
- Areas we cannot reach or that can’t be tested
- Moisture spread under the membrane
If in doubt, call 07833 053749 or drop us an email and we’ll point you to the right survey before booking. The full list of what we check.
What this survey covers

What electronic leak detection looks like in Grove Park
About 1.6 miles north-east lies Eltham Palace, a reminder of how long the area around Grove Park has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Grove Park is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Shop and office owners around The Glades may find that a flat roof over a business is out of sight and out of mind until it leaks. For an older house near a landmark such as St Augustine's Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you let a flat or house near Grove Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
