How electronic leak detection works in Bulls Cross
Electronic testing locates holes in the waterproofing but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. 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’ve noticed patched roofs that still leak and gaps at membrane joints, a survey will tell you what’s going on, whatever the roof.
Flat roofs on exposed homes in small places like Bulls Cross take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

What affects the cost of electronic leak detection
A few things affect what a survey costs:
- Height and safe access
- Chimneys, valleys, parapets and other details
- The type of building, from a house to a block or an office
- Extra roofs, like extensions, dormers or garages
To find out what your survey will cost, phone 07833 053749 or email us with the address and some details. We’ll confirm the figure before booking.
What to let us know when you get in touch
You do not need to know any roofing terms. Just let us know:
- Any deadline, like an exchange date
- The type of building and roof, such as pitched or flat
- Whether there’s a loft hatch, a shared roof or tricky access
- Pictures of the roof from a safe spot, if you have them
We confirm the price for the job before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or email us.
What we are asked to look at in Bulls Cross
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs, depending on the build-up.
Here are some of the things we see often:
- Gaps at membrane joints
- Patched roofs that still leak
- Leaks under green or ballasted roofs
- Leaks showing away from the breach
For site and facilities teams at buildings like Capel Manor Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before booking anyone
- When you’ll get the report
- What follow-up you get after the report
- Whether VAT is in the quoted price
- Whether the loft space is looked at, where there is one
Can I check my roof myself?
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What we do, step by step
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. The survey normally takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. Somewhere like Bulls Cross needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- 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.
Before the survey
- Check the loft hatch can be reached
- Keep pets out of the way during the survey
- For flats, check roof access has been agreed

What electronic leak detection looks like in Bulls Cross
About 0.7 miles south-west lies Forty Hall, a reminder of how long the area around Bulls Cross has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Landlords with a home close to Turkey Street station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a shop, office or commercial unit, for instance near Edmonton Green Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Questions from Bulls Cross
Does a conservation area affect roof work in Bulls Cross?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is Bulls Cross within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
What’s the price of ELD?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. For a quote, phone 07833 053749 or use the contact form.
Leave it or get it looked at?
Patching where you think the leak is often misses it. ELD shows the actual breach points. For older village homes like those around Bulls Cross, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.

Practical tips
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Don’t leave water getting in
- Avoid repeated repairs without finding the cause
- Use boards when working on the roof
- Clear flat roof outlets regularly
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
