What electronic leak detection looks like in Mop End
A number of Buckinghamshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Hughenden Manor about 4.1 miles west, Mop End sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Anyone responsible for a site like Curzon Church of England Combined School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For an older house near a landmark such as Church of the Holy Trinity, flat-roofed rear additions and dormers added over the years are worth checking.
Mop End is about 3 miles west of Amersham, in Buckinghamshire. In Mop End, as across Buckinghamshire, every roof gets the same careful survey. Across Buckinghamshire, we cover Mop End and the places around it. For surveys nearby, see our Reading page.

How electronic leak detection works in Mop End
Our ELD testing covers flat roofs in Mop End and the rest of London and South East England. Testing normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. You get a written report with photos. Common reasons to book are leaks showing away from the breach and holes left by work on the roof, across green roofs, roof terraces and balconies and single-ply roofs.
Somewhere as small as Mop End, flat roofs tend to be on extensions, garages and converted outbuildings. 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 when booking.
Nothing in the report is left vague: if work is needed, the report says so clearly.

Useful tips for Mop End property owners
Most of what helps is simple and safe from the ground. Our suggestions:
- Get leaks traced quickly
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
- Clear flat roof outlets regularly
Wet insulation may need attention after a leak. Your roofer can advise on that and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
What happens on the day
We work from the outside in: outside views come first, then the roof space if there’s safe access. In total, it takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. In a small place like Mop End, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Preparing for the visit
- Dig out any old roof reports or invoices
- Leave side gates unlocked
- Keep pets inside or away from the areas we are looking at

FAQs for Mop End
Is my home in Mop End listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Mop End within the area you cover?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we will say so before testing.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
What does the report include?
You get our findings in writing, part by part, with photos. The most urgent items are made clear.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through so we can pinpoint it.
How do I book a survey in Mop End?
Simply phone 07833 053749 or use the contact form with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Do you need electronic leak detection in Mop End?
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems such as:
- Leaks at pipes, outlets or fixings
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Punctures from foot traffic or tools
Landlords with a home close to Amersham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
