Electronic leak detection in Pachesham Park, Surrey
Electronic leak detection to pinpoint holes in flat roof membranes in Pachesham Park. We’ve completed more than 5,000 surveys across London and the South East.
- Punctures from foot traffic or tools
- New roofs to check before paving or planting
- Breaches hidden under paving or planting
When to book a survey in Pachesham Park
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Here are some of the things we see often:
- Repairs that haven’t stopped the leak
- Holes around roof penetrations
- Water coming in under a flat roof
- Leaks showing away from the breach
Anyone responsible for a site like Therfield School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Questions to ask before booking
- Is there a chance to talk the report through?
- Which viewpoints they use to see the roof
- Whether they hold professional indemnity and public liability insurance
- What experience they bring
Electronic leak detection in Pachesham Park: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it is covered. Each roof is quoted 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’re often asked to look into leaks that return after repairs and new membranes needing a check before handover, on green roofs, liquid-applied waterproofing and flat roof membranes.
In a village or hamlet like Pachesham Park, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report works through the roof section by section, from the coverings down to the gutters. You’ll see the good as well as the bad.

Local flat roofs in Pachesham Park
Historic houses such as The Homewood, about 3 miles north-west, show how far back building in the area around Pachesham Park goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Landlords with a home close to Ashtead station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for instance near The Ashley Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Pachesham Park is about 2 miles north-west of Ashtead, in Surrey. If you’re in Pachesham Park, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Pachesham Park is one of the places in Surrey we cover for electronic leak detection. We also survey roofs in Guildford.

How the survey changes by roof type
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Your questions about electronic leak detection in Pachesham Park
Do you carry out roof surveys in Pachesham Park?
We do. Every survey there gets the same written report with photos.
Is my home in Pachesham Park listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
Do you use low-voltage or high-voltage testing?
We choose the method that suits the roof. We will explain why when we quote.
Do you look in the roof space?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We’ll tell you if yours is not suitable before testing.
Do I need to be at home?
That depends on the survey. For inside areas and the roof space, someone has to give us access.
What we can’t see
Before booking, it’s worth knowing what a survey won’t do:
- Build-ups without a suitable layer below
- Water entering through details rather than the membrane
- Parts of the roof covered by fixed equipment
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you. What a survey covers and does not.
What we check
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Green roofs
- Roof terraces and balconies
What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. In a place like Pachesham Park, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why us?

What we do, step by step
Once we have finished looking, we write up our findings in a report with photographs. As for time on site, most surveys take a time that depends on the size of the roof and how it’s built, which we set out in the quote. Older rural homes like those around Pachesham Park can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Mention any parking restrictions on your street
- If you are buying, let the agent know when we are coming
- Have keys ready for side gates, garages or roof access doors
