How electronic leak detection works in Gilbert Street
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a photo-illustrated written report of each breach found. If you’re worried about a flat roof leak that can’t be traced and new membranes needing a check before handover, we can find out what’s behind it, on liquid-applied waterproofing, single-ply roofs and roof terraces and balconies alike.
In a village or hamlet like Gilbert Street, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Prices for electronic leak detection in Gilbert Street
Several things affect the price of a survey:
- How tall the building is and how easy the roof is to see
- The use of thermal imaging or a drone
- How big the roof is
- Commercial roofs and larger buildings
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Helping us price your survey
These details help when you contact us:
- Your postcode, so we can check access and travel

Booking is simple: just call 07833 053749 or send us an email, let us know about the property and we will suggest the right survey. The price is agreed up front.
Tips from our surveys
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check new waterproofing before handover
- Check trades protect the waterproofing
- Keep a note of leaks after rain
- Have roof specifications to hand
If water has been getting in, insulation under the membrane may be wet. That is something to discuss with your roofer and other checks can help judge it.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
The survey, step by step
The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Gilbert Street needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect everything that’s safely in view, inside and out.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Buyers: confirm access with the estate agent or seller
- Tell us where we can park nearby
How to book
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.

Your questions about electronic leak detection in Gilbert Street
Does a conservation area affect roof work in Gilbert Street?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you come out to Gilbert Street?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you get in touch and we’ll explain what’s needed.
Do you survey on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
What we’re asked to look at in Gilbert Street
Joints and laps in a membrane can fail over time. Small openings at laps can leak long before anyone notices.
Problems we come across often include:
- Leaks showing away from the breach
- Leaks through a covered membrane
- Breaches around outlets and penetrations
- A flat roof leak that cannot be traced
For site and facilities teams at buildings such as Ropley Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Questions to ask before booking
- What the report includes, and whether it has photos
- Whether VAT is added on top
- Which viewpoints they use to see the roof
- Whether you can ask questions once you have the report
What electronic leak detection does not cover
We only report whatever is safely visible on the day, so there are some things a survey can’t cover:
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that is for your roofer)
- How wet the insulation is
If in doubt, call 07833 053749 or drop us an email and we will recommend the right survey before you book. What our survey covers.

Flat roofs in Gilbert Street
The wider area around Gilbert Street has a long history of building, with Bentworth Hall about 4.2 miles north. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Some Hampshire villages still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If your home is one of the older ones in the streets near Church of St Peter, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
