Electronic leak detection in Apsley
We carry out electronic leak detection on flat roofs in Apsley and across London and South East England. A visit usually takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Electronic leak detection is quoted for your roof, because the method depends on the roof. You get a photo-illustrated written report. We survey roof terraces and balconies, commercial flat roofs and liquid-applied waterproofing, and people most often book us about gaps at membrane joints and leaks that return after repairs.
Around a smaller place like Apsley, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to.

Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf. Access is agreed with the tenant ahead of time.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, and they’re priced for the size.
Flat roofs in Apsley
Apsley is part of Hemel Hempstead, 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. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take a building like Two Waters Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Apsley station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Apsley is about 1 mile south of Hemel Hempstead, in Hertfordshire. Whether the building in Apsley is a house, a flat or a commercial unit, we can survey the roof. Apsley is one of the places in Hertfordshire we cover. We also survey roofs in London.

What electronic leak detection does not cover
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Some conductive membranes
- How wet the insulation is
- Leaks from plumbing or windows

Roof types and parts we check
- Commercial flat roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Green roofs
- Flat roof membranes
- Single-ply roofs
Before and after the survey
There is plenty you can do without going near the roof. Here’s what helps most:
- Get leaks traced quickly
- Avoid repeated repairs without finding the cause
- Use boards when working on the roof
- Keep outlets clear of debris
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.

Do you need electronic leak detection in Apsley?
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Most people get in touch when they’ve noticed one of these:
- Punctures from foot traffic or tools
- Leaks through a covered membrane
- Leaks through a flat roof with no obvious cause
- Waterproofing to test before it is covered
High Elms Manor lies about 4.1 miles south-east, so building around Apsley goes back a long way. Older homes nearby may have later flat-roofed extensions or dormers, often re-covered more than once.
Before booking anyone
- Their track record with similar roofs
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Their insurance cover
- When you’ll get the report
What we do, step by step
The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. Parking around Apsley is typically easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Let us know about parking before the day
- If you’re buying, check with the agent that we can get in
- Clear the way to the loft hatch

Related advice
What happens if roof problems are left?
Patching where you think the leak is often misses it. ELD shows the actual breach points. Around Apsley, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.

FAQs for Apsley
Should a flat-roofed garage or porch in Apsley be checked too?
It is often worth it, as these roofs are easy to forget. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
Will you come out to Apsley?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
How do I book a survey in Apsley?
Simply ring 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date.
Can you give me structural calculations?
No. Visible signs like 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.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we’ll agree the details when you book.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
