Hunsdonbury Electronic Leak Detection

Electronic leak detection for homes and businesses in Hunsdonbury
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We’ll say if ELD won’t work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It saves a wasted visit. We survey green roofs, single-ply roofs and commercial flat roofs, and common reasons people get in touch are leaks showing away from the breach and holes left by work on the roof.
Some older homes in villages like Hunsdonbury are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

Flat roofs in Hunsdonbury
The wider area around Hunsdonbury has a long history of building, with Much Hadham Palace about 4 miles north. 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. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Roydon station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Take an older house close to St Francis Chapel: flat-roofed rear additions and dormers added over the years are worth checking.

Why act early in Hunsdonbury
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first so your roofer knows where to work. In a small place like Hunsdonbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Hunsdonbury questions
Do you cover smaller places like Hunsdonbury?
Yes. Hunsdonbury is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you cover Hunsdonbury?
We do. Every survey there gets the same written report with photographs.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
Which days do you carry out surveys?
Surveys run seven days a week. To find a day that suits you, ring 07833 053749 or send us an email.
Will you go up on the roof?
Only if it’s safe. We inspect what can be seen safely: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
How much time does ELD need?
It usually takes more time on a big roof than a small one, with the construction of the roof playing a part too.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
What we’re asked to look at in Hunsdonbury
When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs, depending on the build-up.
Things that frequently lead to a survey include:
- Failed seams and laps
- Breaches around outlets and penetrations
- Leaks through a covered membrane
- New roofs to check before paving or planting
For site and facilities teams at buildings such as Hunsdon Junior Mixed and Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before you book.

What else we do in Hunsdonbury
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Get leaks traced quickly
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
- Have roof specifications to hand
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
Roof by roof
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check this first.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
