Electronic leak detection in Holmethorpe
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We survey liquid-applied waterproofing, green roofs and flat roof membranes, and the problems we are asked to look at most are new membranes needing a check before handover and leaks at pipes, outlets or fixings.
Around Holmethorpe, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when booking. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Practical tips
A little preparation and a few simple habits help. Our tips:
- Keep a note of leaks after rain
- Act on new leaks promptly
- Avoid repeated repairs without finding the cause
- Tell us about the membrane and build-up if you know it
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
What happens on the day
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, from the ground, from windows, in the loft space and by drone where it applies. Most surveys take a time that depends on the membrane area and the build-up, which we set out in the quote. Being in a smaller place like Holmethorpe doesn’t change how the visit works: we look from ground level, from windows, from the loft and from the roof where it’s safe. It is useful to show us anything you’ve already noticed.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Mention any parking restrictions on your street
- Dig out any old roof reports or invoices
- If the roof is shared, arrange access with whoever manages the building

Advice
What happens if roof problems are left?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Blocked gutters on homes around Holmethorpe overflow and soak walls. It’s easy to sort the cause early and slow to dry a damp wall.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Electronic leak detection in Holmethorpe: local notes
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Shop and office owners around The Belfry may find that a flat roof over a business is out of sight and out of mind until it leaks. If your house is among the older ones in the streets near Holy Trinity, the joins between later flat roofs and the old walls are where problems normally start. For landlords with property near Redhill station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Holmethorpe is about 1 mile north-east of Redhill, in Surrey. Holmethorpe gets the same service as everywhere else we work: a careful inspection, photos and a written report. Holmethorpe is one of the places in Surrey we cover. We also survey roofs in Crawley.

Common questions in Holmethorpe
Do you cover Holmethorpe?
Yes, Holmethorpe is within the area we cover. We work right across London and South East England. You can phone 07833 053749 or use the contact form with the address and some details, and we will talk through which survey suits.
How do I find out if my home in Holmethorpe is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, phone 07833 053749 or send us an email.
Can you survey in bad weather?
Light rain doesn’t usually stop a survey, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
Honest limits
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Roofs whose membrane or build-up is not suitable
- Leaks from plumbing or windows
- How wet the insulation is
If in doubt, phone 07833 053749 or drop us an email and we’ll suggest the right survey. What a survey covers and does not.
Roof types and parts we check
- Green roofs
- Flat roof membranes
- Commercial flat roofs
- Single-ply roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
Checking the roof from the ground
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
