Electronic leak detection in Aldenham: what you get
Our ELD testing covers flat roofs in Aldenham and the rest of London and South East England. Testing usually takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. Every roof is quoted on its size and build-up. The results come in a written report with photos. We survey flat roof membranes, single-ply roofs and liquid-applied waterproofing, and common reasons people get in touch are leaks at pipes, outlets or fixings and stains far from any visible defect.
In a village or hamlet like Aldenham, 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. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when booking.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

The survey, step by step
Safety comes first on every visit. Everything that can safely be seen is inspected, and if part of the roof can’t be seen, the report says so. The survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Aldenham often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
How to prepare
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear
- Leave a clear route to the loft

Advice
Practical tips
From years of surveys, a few habits stand out:
- Don’t leave water getting in
- Use boards when working on the roof
- Record dates and spots where water appears
- Let us know about the membrane and build-up if you know it
If anything in the report isn’t clear, ask us. We can talk you through the findings.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.

Do you need electronic leak detection in Aldenham?
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Things that often lead to a survey include:
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Leaks that return after repairs
- Gaps at membrane joints
For site and facilities teams at buildings such as Fair Field Junior School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Flat and commercial roofs around Aldenham
Historic houses such as High Elms Manor, about 2.5 miles north-west, show how far back building in the area around Aldenham goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you let a flat or house near Garston station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. Take an older house close to Church of St John the Baptist: the joins between later flat roofs and the old walls are where problems typically start.

What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. In a place like Aldenham, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
