Markyate Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes for Markyate, from an experienced roof surveyor. You get a clear written report with photos.
- Waterproofing to test before it’s covered
- Leaks showing away from the breach
- Leaks through a flat roof with no obvious cause
Different roofs, different checks
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Electronic leak detection for homes and businesses in Markyate
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves and some roofs do not have a suitable layer beneath the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Any details you have about the membrane and build-up help us decide, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey liquid-applied waterproofing, roof terraces and balconies and flat roof membranes, and people most often book us about new membranes needing a check before handover and punctures from foot traffic or tools.
In smaller places like Markyate, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

How the survey works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take as long as needed for the roof’s area and construction, which we set out in the quote. For a survey in Markyate, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey

Advice
Common questions in Markyate
Does a conservation area affect roof work in Markyate?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Markyate in the area you cover?
Yes. We cover the whole of London and South East England, and Markyate is part of that. You can phone 07833 053749 or use the contact form with the address and some details.
What happens next?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Does someone need to be in?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
Can you find leaks on a covered flat 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 you use drones?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Will you walk on the roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
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 Markyate?
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Here are some of the things we see frequently:
- Breaches hidden under paving or planting
- Damage from equipment installers
- Repairs that haven’t stopped the leak
- Leaking laps in the waterproofing
The streets around a church such as Markyate Methodist Church are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems typically start.
Choosing a roof surveyor
- How much experience they have with roofs like yours
- Which parts of the roof they’ll actually see
- Whether you can ask questions once you have the report
- Whether the inside of the roof is included
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Test new membranes before covering them
- Clear flat roof outlets regularly
- Stay off the flat roof unless needed
- Act on new leaks promptly
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.

What electronic leak detection looks like in Markyate
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 check with the council. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as The Mall Luton, a flat roof over a business is out of sight and out of mind until it leaks. If you own a rental within reach of Luton Airport Parkway station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

- Areas we cannot reach or that cannot be tested
- Carrying out the repair work
- Water entering through details rather than the membrane
