Electronic leak detection in Gatton
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. If neither method suits your roof, we will tell you at the outset. We survey flat roof membranes, liquid-applied waterproofing and roof terraces and balconies, and the problems we are asked to look at most are gaps at membrane joints and stains far from any visible defect.
In a village or hamlet like Gatton, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: 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 when you book.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Do you need electronic leak detection in Gatton?
Joints and laps in a membrane can fail over time. A gap that is hard to see can let water in long before anyone notices.
It’s worth booking a survey if you’ve seen:
- Leaks showing away from the breach
- New membranes needing a check before handover
- Gaps at membrane joints
- Breaches around outlets and penetrations
If your home is one of the older ones in the streets near St Andrew's Church, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- Are they insured for the work?
- Whether you get a written report with photos
- What happens after the report arrives
- How soon the report will arrive
What this survey can’t tell you
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- Moisture spread under the membrane
- Fixing the holes we find
- Leaks from plumbing or windows
If in doubt, ring 07833 053749 or email us and we’ll recommend the right survey. What our survey covers.

Common questions in Gatton
Does a conservation area affect roof work in Gatton?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Gatton?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access when you book.
Will you check the loft?
Typically, if there is one and it can be reached safely. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Can you survey in bad weather?
A survey can normally go ahead in light rain. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we will arrange another day with you.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with whoever owns or manages the building. Let us know about it as you book and we will plan the survey around it.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Consider ELD before paving or planting goes on
- Limit access to the roof
- Ask contractors to protect the membrane
- Tell us about the membrane and build-up if you know it
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Surveys for landlords and agents in Gatton
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Local flat roofs in Gatton
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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list.
For businesses in and around places like The Belfry, the flat roofs over shops and commercial units are worth checking before a leak, not after. Landlords with a home close to Merstham station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Different roofs, different checks
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
How it works
The visit has one job: to see as much of the flat roof membrane as can be seen safely and record it clearly. Notes and photographs go into the written report. It typically takes a length of time set by the roof’s area and construction, which we’ll explain when we quote. Older roofs in small places like Gatton can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before the survey
- Let us know about any leaks, stains or damp patches you know of
- Have any questions written down, so nothing gets missed
- Leave a clear route to the loft
