Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Do not let outlets block
- Keep a note of leaks after rain
- Limit access to the roof
- Don’t leave water getting in
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Electronic leak detection for homes and businesses in Great Yeldham
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. Common reasons to book are holes left by work on the roof and patched roofs that still leak, on roof terraces and balconies, commercial flat roofs and green roofs.
In a village or hamlet like Great Yeldham, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
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.

Flat roofs in Great Yeldham
About 2.3 miles south-east lies Hedingham Castle, a reminder of how long the area around Great Yeldham has been built on. 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 the council can say whether a home is in a conservation area. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, while many towns grew with post-war and newer estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like St Andrew's Church of England Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

When to book a survey in Great Yeldham
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Common reasons to book include:
- Holes around roof penetrations
- Stains far from any visible defect
- Waterproofing to test before it is covered
- Gaps at membrane joints
If you live in an older home near Parish Church of St Andrew, the joins between later flat roofs and the old walls are where problems typically start.
Before booking any roof surveyor
- What happens after the report arrives
- Whether any drone flown is registered with the CAA
- Whether the roof space is looked at, where there is one
- Whether they hold professional indemnity and public liability insurance
Leave it or get it looked at?
Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first, so the repair can be targeted. Outbuildings and barns around Great Yeldham are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.

The survey, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Great Yeldham, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
Before the survey
- Clear the way to the loft hatch
- Let us know about parking near the property
- Keep pets inside or away from the areas we are looking at

Questions from Great Yeldham
Is my home in Great Yeldham listed or in a conservation area?
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.
Do you carry out roof surveys in Great Yeldham?
Yes. We survey roofs across London and South East England, and Great Yeldham is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
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.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through, which shows us where the hole is.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We’ll discuss it before we quote.
How do I arrange electronic leak detection in Great Yeldham?
To book, ring 07833 053749 or email us and tell us the address and what you need to know. We will confirm the price and find a day that suits.
What you can safely check yourself
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.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
Different roofs, different checks
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll say if the test will not work.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
