Electronic leak detection in Old Dean
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof cannot be tested. Typical surveys look at leaks under green or ballasted roofs and new roofs to check before paving or planting, across single-ply roofs, liquid-applied waterproofing and commercial flat roofs.
Outbuildings, garden rooms and garages in places like Old Dean often have flat roofs of their own. They’re rarely looked at until something gets wet. It’s worth mentioning them when booking, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Findings are set out part by part, from the coverings down to the gutters. You will see the good as well as the bad.

Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Make sure trades protect the waterproofing
- Limit access to the roof
- Do not keep patching the same spot
- Share any drawings of the roof
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
Why it is worth a survey now in Old Dean
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Homes in smaller places like Old Dean can face more weather, so a loose ridge or verge soon lets rain in. Each storm lifts it a little further, and water follows.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Read how roof surveys are priced and two real surveys.
What affects the cost of electronic leak detection
All our prices include VAT. The things that change the price are:
- The height of the building and how the roof can be seen safely
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
- Commercial roofs and larger buildings
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Getting in touch
There is no need for technical words. Just tell us:
- How the loft is reached, if there is one
- Pictures of the roof from a safe spot, if you have them
- Your timetable, such as an exchange date
- Any stains, drips or damp patches you’ve seen indoors
To book a survey, ring 07833 053749 or drop us an email and tell us the address and what’s prompted the survey. You will know the price before anything is booked.
How the survey works
Safety comes first on every visit. Everything that can safely be seen is inspected, and if part of the roof cannot be seen, the report says so. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. In a smaller place like Old Dean, as anywhere, the forecast plays a part: drone flights and thermal imaging need the right conditions, while a look from the ground and the loft can go ahead in most weather.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Check pets are kept safely away
- Leave a clear route to the loft
- Agree roof access with the managing agent if it is shared

Old Dean: your questions answered
Is Old Dean within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is Old Dean in the area you cover?
Yes, Old Dean is within the area we cover. We survey roofs across London and South East England. You can ring 07833 053749 or email us with the address and some details, and we’ll talk through which survey suits.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We can only inspect what we’re given access to.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Is this an asbestos survey?
No. Asbestos surveys and testing aren’t part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Electronic leak detection in Old Dean: local notes
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. 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, before anyone quotes for re-roofing.
For landlords with property near Camberley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like Collingwood College will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. The streets around a church like St Martin's Church are often among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
