Electronic leak detection in Anstey: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, ideally before any re-roofing is planned.
Take a building like Anstey First School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Anstey
There are different ELD methods. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. If you’re worried about breaches hidden under paving or planting and water coming in under a flat roof, we can find out what’s behind it.
Some older homes in villages like Anstey are listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what isn’t.

What we are asked to look at in Anstey
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Common reasons to book include:
- Stains far from any visible defect
- Failed seams and laps
- Holes left by work on the roof
- Breaches around outlets and penetrations
If you live in an older home near Church of St George, the joins between later flat roofs and the old walls are where problems normally start.
Before booking any roof surveyor
- What the survey will not cover
- Their insurance cover
- How soon the report will arrive
- Whether you can ask questions once you have the report
For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Mention it when you contact us and we’ll plan the visit with that in mind.
Letting agents frequently book on a landlord’s behalf. We agree a time with the tenant beforehand.
What affects the price in Anstey
When we price a survey, we consider:
- How big the roof is
- Commercial roofs and larger buildings
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
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.
What to tell us when you contact us
Some details help us suggest the right survey and price. When you contact us, let us know:
- What’s prompted the survey
- Any photos you have, taken from the ground or a window
- How the loft is reached, if there is one
- Your timetable, such as an exchange date
Every survey is priced before it is booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, call 07833 053749 or email us.
Why it is worth a survey now in Anstey
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Outbuildings and barns around Anstey are easy to forget, but a failed roof there can spoil what’s stored inside. It’s worth including them in a survey before a winter does the damage.

The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like Anstey needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it’s safe.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Move anything stored under the loft hatch
- Check pets are kept safely away
- Let us know about parking near the property
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or send us an email when you’re ready.

No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- Repairing the breaches (that’s for your roofer)
- Areas we can’t reach or that cannot be tested
- The extent of water in the insulation

Anstey: your questions answered
Do you cover smaller places like Anstey?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is Anstey in the area you cover?
Yes. We work right across London and South East England, and Anstey is part of that. Just phone 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Do you test for asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Do you need to get into the loft?
Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when you book.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos so your roofer can fix them.
