Electronic leak detection in Ash Vale, Surrey
Wondering about the flat roof membrane at a property in Ash Vale? You can book electronic leak detection in Ash Vale and across Surrey.
- Leaking laps in the waterproofing
- Damp inside with no sign on the roof
- Damage from equipment installers
Practical tips
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Find the breach before more patching
- Make sure trades protect the waterproofing
- Keep a note of leaks after rain
- Test new membranes before covering them
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.
Electronic leak detection in Ash Vale
A leak in a flat roof frequently shows up a long way from where the water gets in. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself, to find where it has been breached. It’s testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. If you’ve noticed leaks showing away from the breach and damage from equipment installers, we can find out what’s behind it, on liquid-applied waterproofing, commercial flat roofs and single-ply roofs alike.
In a smaller place like Ash Vale, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

FAQs for Ash Vale
Does a conservation area affect roof work in Ash Vale?
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.
Is Ash Vale within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
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 so we can pinpoint it.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Does ELD include fixing the breach?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
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 find leaks on a covered flat roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Do you need electronic leak detection in Ash Vale?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny, but still let water through.
Here are some of the things we see often:
- Breaches around outlets and penetrations
- New membranes needing a check before handover
- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
Take a building like Shawfield Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
What to check before booking
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether you can ask questions once you have the report
- Which parts of the roof they’ll actually see
- Is VAT included in the price?
Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Local flat roofs in Ash Vale
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. 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. Historic houses such as Wanborough Manor, about 3.6 miles south-east, show how far back building in the area around Ash Vale goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If you let a flat or house near Ash Vale station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you live in an older home near St Mary's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What we do, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit typically takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. With a bit of garden around a house, as there often is around Ash Vale, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Clear the way to the loft hatch
- Make sure we can get to the back of the property
- Keep pets in another room

Advice
Surveys for landlords and agents in Ash Vale
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Let us know about it as you book and we will plan the survey around it.
When you need someone else
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Areas we can’t reach or that cannot be tested
- Moisture spread under the membrane
- Repairing the breaches (that is for your roofer)
