Rooks Nest Electronic Leak Detection
A careful look at the flat roof membrane at your property in Rooks Nest, and put it all in a photo-illustrated written report.

- Repairs that haven’t stopped the leak
- Holes left by work on the roof
Surveys for landlords and agents in Rooks Nest
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
Electronic leak detection in Rooks Nest
We carry out electronic leak detection on flat roofs in Rooks Nest and across London and South East England. Testing normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you’ve noticed leaks through a flat roof with no obvious cause and new membranes needing a check before handover, we can find out what’s behind it, on liquid-applied waterproofing, flat roof membranes and roof terraces and balconies alike.
In a small place like Rooks Nest, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Do you need electronic leak detection in Rooks Nest?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
It is worth booking a survey if you’ve seen:
- Leaking laps in the waterproofing
- Repairs that haven’t stopped the leak
- Holes left by work on the roof
- Leaks showing away from the breach
Take an older house close to Church of Saint Nicholas: the joins between later flat roofs and the old walls are where problems typically start.
Before you book any roof surveyor
- Whether the loft space is looked at, where there is one
- When you’ll get the report
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether the price includes VAT
What happens on the day
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit normally takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. Somewhere as small as Rooks Nest, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Let us know about parking before the day
- Note where any stains or damp appear
- Buyers: confirm access with the estate agent or seller

Advice
Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Consider ELD before paving or planting goes on
- Act on new leaks promptly
- Limit access to the roof
- Use boards when working on the roof
You receive a report showing where each breach was found, with photos. Your roofer uses it to carry out repairs.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Leave it or get it looked at?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached so attention can go to the right place. For older village homes like those around Rooks Nest, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You’ll know the exact price before booking.

What electronic leak detection looks like in Rooks Nest
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Rooks Nest is part of Stevenage, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
Landlords with a home close to Stevenage station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Aston Bury, about 3.7 miles south-east, is one of the historic houses in the wider area around Rooks Nest. Older homes nearby may have later flat-roofed extensions or dormers, frequently re-covered more than once.

Your questions about electronic leak detection in Rooks Nest
Is my home in Rooks Nest listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Should a flat-roofed garage or porch in Rooks Nest be checked too?
Often, yes, so mention it when booking. Flat-roofed garages and porches are common in new towns like Stevenage, and older felt coverings may be near the end of their life.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Mention it when you get in touch and we will explain what’s needed.
Does electronic leak detection work on all membranes?
ELD doesn’t suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof won’t work, we’ll say so at the start.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Should I look at the roof myself first?
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
