Electronic leak detection in Great Hollands: what you get
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We survey flat roof membranes, single-ply roofs and green roofs, and people most often book us about repairs that haven’t stopped the leak and damage from equipment installers.
Flat roofs in smaller places like Great Hollands can be more exposed, especially where nothing shelters them, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Without opening up the roof, some things stay hidden, and that sets some limits:
- Build-ups without a suitable layer below
- Fixing the holes we find

Questions from Great Hollands
Should a flat-roofed garage or porch in Great Hollands be checked too?
Frequently, yes, so mention it as you book. Many homes in new towns like Bracknell have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Does a conservation area affect roof work in Great Hollands?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will I get photos?
Yes. The report includes photos of what we found, so you can see each point for yourself.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or email us.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. What sits on the membrane affects the method, so we check the build-up first.
Do I need to be at home?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.

What we do, step by step
When we arrive, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. Most surveys take a time that depends on the size of the roof and how it’s built, which we set out in the quote. A visit to Great Hollands is planned like any other: the time, the access and where to park are agreed in advance. Visits can be on weekdays, Saturdays or Sundays. Let us know about any garages, outbuildings or extensions you want included.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- 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.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey

- Clear the way to the loft hatch

Flat and commercial roofs around Great Hollands
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a shop, office or commercial unit, for instance near The Lexicon, a flat roof over a business is out of sight and out of mind until it leaks. Anyone responsible for a site like Great Hollands Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

What you can safely check yourself
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
Do you need electronic leak detection in Great Hollands?
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Some are too small to see, but still let water through.
Things that often lead to a survey include:
- Leaking laps in the waterproofing
- Waterproofing to test before it is covered
- Leaks under green or ballasted roofs
- Leaks that return after repairs
If you let a flat or house near Bracknell station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
