What happens on the day
After the inspection, everything we found is written up in a report with photographs. As for time on site, most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. A visit to Shephall is planned like any other: the time, the access and where to park are agreed beforehand. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.

About our electronic leak detection in Shephall
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. Common reasons to book are leaks under green or ballasted roofs and holes around roof penetrations, across roof terraces and balconies, single-ply roofs and flat roof membranes.
Around Shephall, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when you book, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

When to book a survey in Shephall
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey can pick up problems such as:
- Leaks showing away from the breach
- New membranes needing a check before handover
- Water coming in under a flat roof
- Leaks at pipes, outlets or fixings
Take an older house close to Church of Saint Mary: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Choosing a roof surveyor
- What experience they bring
- When you will get the report
- What’s outside the scope of the survey
- Whether the inside of the roof is included
Electronic leak detection in Shephall: local notes
Historic houses like Aston Bury, about 1.6 miles south-east, show how far back building in the area around Shephall goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Shephall is part of Stevenage, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
If you own a rental within reach of Stevenage station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Peartree Spring Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Shephall is about 1 mile south of Stevenage, in Hertfordshire.

Tips from our surveys
Some practical points come up on survey after survey. They apply to most roofs:
- Keep outlets clear of debris
- Share any drawings of the roof
- Avoid repeated repairs without finding the cause
- Use boards when working on the roof
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Your questions about electronic leak detection in Shephall
Will you come out to Shephall?
Yes, Shephall is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Are flat-roofed garages and porches in Shephall worth including?
Normally, yes: tell us about it as you book so the visit can include it. Flat-roofed garages and porches are common in new towns like Stevenage, and older felt coverings may be near the end of their life.
How long will testing take?
Testing usually takes as long as needed for the membrane area and the build-up, which we set out in the quote.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
How does ELD work?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Why act early in Shephall
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. In a smaller place like Shephall, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Wind gets under it and lifts more, and water follows.
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.
