Why get it checked now?
Patching where you think the leak is often misses it. ELD shows the actual breach points. In a small place like Childwick Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

Electronic leak detection for homes and businesses in Childwick Green
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a photo-illustrated written report. We survey commercial flat roofs, green roofs and roof terraces and balconies, and common reasons people get in touch are damp inside with no sign on the roof and holes around roof penetrations.
In a village or hamlet like Childwick Green, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that’s said too.

What electronic leak detection looks like in Childwick Green
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses such as Childwickbury Manor, about 0.4 miles south-west, show how far back building in the area around Childwick Green goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Harpenden station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a shop, office or commercial unit, for instance near Village Arcade St Albans, flat roofs over shops and units are easy to forget until water comes through a ceiling. For site and facilities teams at buildings such as Townsend Church of England School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

The visit typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote.

After that, the survey runs as it would anywhere.

- The surface is prepared for the chosen method.
- Testing runs across the agreed area.

No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them.
Can you find leaks on a covered flat roof?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
Prices for electronic leak detection in Childwick Green
We confirm the price for the job before you book. These are the things that affect it:
- The use of thermal imaging or a drone
- Roof area
- Whether it is a home or a commercial building
- Chimneys, valleys, parapets and other details
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
To price your survey accurately, we will ask about:
- Any marks or damp showing indoors
- Photos of the roof, taken safely from ground level or a window
- The address and postcode of the property
- Whether there is a loft hatch, a shared roof or tricky access
If you have photos of the roof, send them over. Take them safely from the ground or a window. To send them or to book, phone 07833 053749 or email us.
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Stay off the flat roof unless needed
- Have roof specifications to hand
- Don’t let outlets block
- Use boards when working on the roof
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
