Electronic leak detection in Ashford
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. You’ll also know what to check next. If you are worried about holes around roof penetrations and failed seams and laps, a survey will tell you what’s going on, on flat roof membranes, green roofs and roof terraces and balconies alike.
Houses around a town like Ashford often have a flat roof somewhere, over an extension, garage, porch or dormer. Many are felt, and newer ones may be EPDM rubber or GRP. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is frequently the first sign a flat roof needs attention.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that is said too.

Surveys for landlords and agents in Ashford
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we’ll plan the visit with that in mind.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or email us.
How the survey changes by roof type
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
How it works
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Parking in a town like Ashford is typically simple, but tell us if there is a driveway or any restrictions. We check the roof from ground level and from windows, then from the loft where there’s safe access.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Dig out any old roof reports or invoices
- Check the loft hatch can be reached
- Keep pets out of the way during the survey

Questions from Ashford
Do you carry out roof surveys in Ashford?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
What do I need to do before a survey in Ashford?
Mostly, it’s about access: the loft hatch, any locked gates and where to park in Ashford. Tell us about known leaks or past repairs as well.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. We will talk about access as you book.
Will you go up on the roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Will I get photos?
Yes. Photographs are taken throughout the survey, and they go into the written report alongside our recommendations.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, phone 07833 053749 or drop us an email.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
What electronic leak detection doesn’t cover
Some things cannot be seen without opening up the roof, and that sets some limits:
- How wet the insulation is
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that’s for your roofer)
If you’re not sure which survey you need, ring 07833 053749 or use the contact form and we’ll give you a straight answer before you book. What a survey covers and does not.

Practical tips
From years of surveys, a few habits stand out:
- Use boards when working on the roof
- Clear flat roof outlets regularly
- Keep foot traffic on flat roofs to a minimum
- Have roof specifications to hand
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Flat and commercial roofs around Ashford
If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take a building like Spelthorne College: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. The streets around a church such as Parish Church of St Matthew are frequently among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Ashford Surrey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where applicable.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
