About our electronic leak detection in Ashtead
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. If you’re worried about punctures from foot traffic or tools and breaches hidden under paving or planting, we can find out what’s behind it, on commercial flat roofs, roof terraces and balconies and green roofs alike.
In a town like Ashtead, a good many shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile. A careful look at outlets, upstands and the membrane itself shows where it stands. Let us know who manages the building so access to the roof can be arranged.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

What happens if roof problems are left?
Patching where you think the leak is frequently misses it. Testing shows where the membrane is actually breached. Around Ashtead, gutters that overflow soak the wall below, and damp follows inside. A slipped tile or worn flashing does the same higher up. Neither gets better on its own.
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the exact price before you book.

Flat and commercial roofs around Ashtead
Historic houses such as Fitznells Manor, about 3.7 miles north-east, show how far back building in the area around Ashtead goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you live in an older home near St George's Church, the joins between later flat roofs and the old walls are where problems typically start. For site and facilities teams at buildings like Parsons Mead School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Questions from Ashtead
How do I find out if my home in Ashtead is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Ashtead?
Yes, Ashtead is within the area we cover. We survey roofs across London and South East England. Just call 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when booking.
How much does electronic leak detection cost?
We quote for each roof individually. Send us details of the roof, and phone 07833 053749 or send us an email for a quote.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. 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 is disturbed.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. We will recommend an engineer if we see signs that call for one.
What we can’t see
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- How wet the insulation is
- Areas we cannot reach or that can’t be tested
- Repairing the breaches (that is for your roofer)
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we will tell you before you book. What our survey covers.

When to book a survey in Ashtead
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
People normally book a survey after spotting one of these:
- Water coming in under a flat roof
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
For landlords with property near Ashtead station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Questions to ask before booking
- How long they’ve been surveying roofs
- What happens after the report arrives
- What insurance they carry
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What we do, step by step
Once we have finished looking, we write up our findings as a written report with photographs, sent to you by email. As for time on site, most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. A survey in Ashtead needs access inside and out, including the loft hatch and any rooms with damp. If there is a side gate or a rear garden, let us know how to reach it. Visits can be on weekdays, Saturdays or Sundays.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Let us know where we can park nearby
- Unlock side gates and any roof access doors
- Clear the way to the loft hatch
