Staines Green Electronic Leak Detection
Wondering about the flat roof membrane at a property in Staines Green? We carry out electronic leak detection in Staines Green and across Hertfordshire, with plain-English findings.
- Gaps at membrane joints
- Holes around roof penetrations
- Damp inside with no sign on the roof
Electronic leak detection in Staines Green: what you get
Electronic testing locates holes in the waterproofing, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. 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. We survey flat roof membranes, single-ply roofs and roof terraces and balconies, and common reasons people get in touch are failed seams and laps and leaks through a flat roof with no obvious cause.
Flat roofs on exposed homes in small places like Staines Green take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often 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 normally the first part of a flat roof to go.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

How the survey works
We check the roof from outside and, where it is relevant and there is safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit normally takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Older rural homes like those around Staines Green can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- First, we confirm which roof areas are included.
- 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.
Before we arrive
- Make a note of anything you’d like us to look at
- Point out any leaks or damp patches
- Agree roof access with the managing agent if it is shared

Common questions in Staines Green
Do you carry out roof surveys in Staines Green?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Do you cover smaller places like Staines Green?
Yes, Staines Green is on our map. Villages and rural addresses get the same survey as a town house.
Will you walk on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
How do you choose the testing method?
The roof decides the method. You’ll know which method we plan to use before we start.
How does ELD work?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Can you survey at the weekend?
We carry out surveys on weekdays and at weekends. To find a day that suits you, call 07833 053749 or email us.
How much time does ELD need?
It typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
What we can’t see
Before booking, it’s worth knowing what a survey will not do:
- Roofs whose membrane or build-up is not suitable
- Parts of the roof covered by fixed equipment
- Moisture spread under the membrane
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer. The full list of what we check.
Roof types and parts we check
- Green roofs
- Roof terraces and balconies
- Commercial flat roofs
- Flat roof membranes
- Single-ply roofs
- Liquid-applied waterproofing
What we’re asked to look at in Staines Green
Joints and laps in a membrane can fail over time. A gap that’s hard to see can let water in for months before it shows.
Things that often lead to a survey include:
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
- Leaking laps in the waterproofing
- Waterproofing to test before it is covered
For businesses in and around places such as Howard Centre, a flat roof over a business is out of sight and out of mind until it leaks.
What to check before booking
- What the survey won’t cover
- When you will get the report
- Whether the loft is part of the inspection
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Surveys for landlords and agents in Staines Green
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
Shared roofs need a little more planning: we need access agreed with the building owner or managing agent. Tell us about it when you book and we will plan the visit with that in mind.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Useful tips for Staines Green property owners
Small things make a difference. Some pointers:
- Find the breach before more patching
- Note where leaks show inside and when
- Test new membranes before covering them
- Act on new leaks promptly
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
