Electronic leak detection for homes and businesses in Thundridge
Our ELD testing covers flat roofs in Thundridge and the rest of London and South East England. Testing typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a written report with photos. We are frequently asked to look into failed seams and laps and repairs that haven’t stopped the leak, across green roofs, flat roof membranes and liquid-applied waterproofing.
In a village or hamlet like Thundridge, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later, for example when you want to check whether anything has changed.

What else we do in Thundridge
Flat roofs in Thundridge
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Much Hadham Palace, about 4.8 miles east, show how far back building in the area around Thundridge goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If yours is one of the older homes in the streets near Parish Church of St Mary, the joins between later flat roofs and the old walls are where problems normally start. Landlords with a home close to Ware station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Thundridge is about 1 mile north of Ware, in Hertfordshire. In Thundridge, as across Hertfordshire, every roof gets the same careful survey. Thundridge is one of the towns and villages in Hertfordshire where we work for electronic leak detection. We also survey roofs in London.

FAQs for Thundridge
Is Thundridge in the area you cover?
We do. The survey and report are the same in Thundridge as anywhere else.
Does a conservation area affect roof work in Thundridge?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Does the weather affect the survey?
Light rain doesn’t usually stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather isn’t suitable.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
Do you climb onto every roof?
Only when it is safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the roof space and a drone where applicable.
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.
Should I look at the roof myself first?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
When to book a survey in Thundridge
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Signs worth acting on include:
- New membranes needing a check before handover
- Damage from equipment installers
- Leaks through a flat roof with no obvious cause
- Leaks through a covered membrane
Anyone responsible for a site like Thundridge Church of England Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

- The extent of water in the insulation
