Electronic leak detection for homes and businesses in Nag's Head
Our ELD report shows where each breach was found, with photographs. It tells your roofer exactly where to repair instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We survey commercial flat roofs, single-ply roofs and liquid-applied waterproofing, and people most often book us about new roofs to check before paving or planting and breaches around outlets and penetrations.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Nag's Head, the flat roof is often a shared part of the building.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

How the survey works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Nag's Head runs like any other.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Keep pets out of the way during the survey
- Tell us where we can park nearby
- Agree roof access with the managing agent if it’s shared
How to book
We survey roofs seven days a week. To find a date that works for you, call 07833 053749 or email us.
Advice
Flat roofs in Nag's Head
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Historic houses like Witanhurst, about 1.7 miles north-west, show how far back building in the area around Nag's Head goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Drayton Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For site and facilities teams at buildings like Grafton Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Shop and office owners around Brunswick Centre may find that a flat roof over a business is out of sight and out of mind until it leaks.

What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Building height and the viewpoints available
- Commercial roofs and larger buildings
- If the survey needs thermal imaging or a drone
- How big the roof is
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
Booking your survey
These details help when you get in touch:
- Whether there’s a loft hatch, a shared roof or tricky access
- The address and postcode of the property
- Where any leaks, stains or damp patches show inside
- Why you want a survey: buying, a leak, a storm or new work
Most bookings start with a short call: ring 07833 053749 or drop us an email. You’ll have a price before anything is arranged.
How the survey changes by roof type
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Bituminous membranes
Bitumen roofs can often be tested electronically though the layers below matter.
Rented homes, blocks and businesses
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Your questions about electronic leak detection in Nag's Head
Is my home in Nag's Head listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is Nag's Head in the area you cover?
Yes. We work right across London and the South East, and Nag's Head is part of that. You can call 07833 053749 or send us an email with the address and a few details.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Do you look in the roof space?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather is not right.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can I check my roof myself?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
