Electronic leak detection in Green Tye, Hertfordshire
Electronic leak detection to pinpoint holes in flat roof membranes for Green Tye, from an experienced roof surveyor. Every survey comes with a written report and photos.
- Leaks through a covered membrane
- Failed seams and laps
- Holes left by work on the roof
Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Electronic leak detection for homes and businesses in Green Tye
ELD can be carried out in more than one way. Low-voltage methods usually need a wet roof surface and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. We’ll say if your roof does not suit either method before any testing starts. Common reasons to book are leaks through a covered membrane and leaks showing away from the breach, on commercial flat roofs, liquid-applied waterproofing and green roofs.
Flat roofs on exposed homes in small places like Green Tye 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. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Where we can’t see part of the flat roof membrane, the report says so. That way, it’s clear what was covered and what wasn’t.

What else we do in Green Tye
Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. Older cottages and farmhouses around Green Tye can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
For a price for your roof in Green Tye, ring 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

How the survey works
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. In a hamlet or village like Green Tye, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Keep pets in another room
- Move anything stored under the loft hatch
- Point out any leaks or damp patches
How to book

What we are asked to look at in Green Tye
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
Signs worth acting on include:
- Punctures from foot traffic or tools
- Breaches hidden under paving or planting
- Breaches around outlets and penetrations
- Water coming in under a flat roof
If you let a flat or house near Bishops Stortford station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking anyone
- Which parts of the roof they’ll actually see
- Is VAT included in the price?
- What they will not be able to tell you
- How long they’ve been surveying roofs
Landlord and commercial surveys in Green Tye

If you own several properties, you can book surveys for several addresses. To discuss a number of properties, ring 07833 053749 or use the contact form with the addresses.
Tips that help
Nothing here needs a ladder. A few suggestions:
- Check new waterproofing before handover
- Limit access to the roof
- Keep outlets clear of debris
- Share any drawings of the roof
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Local flat roofs in Green Tye
The wider area around Green Tye has a long history of building, with Much Hadham Palace about 1.3 miles north-west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
The streets around a church like Church of St Thomas are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Your questions about electronic leak detection in Green Tye
Does a conservation area affect roof work in Green Tye?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. 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.
Do you cover Green Tye?
We do. Every survey there gets the same written report with photos.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
What’s the best way to book?
It is easiest to ring 07833 053749 or email us. Give us the address and some details about the roof, and we’ll take it from there. We survey on weekdays, Saturdays and Sundays.
How long will testing take?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.
