How electronic leak detection works in Burnham Green
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. We survey roof terraces and balconies, single-ply roofs and flat roof membranes, and common reasons people get in touch are leaks through a flat roof with no obvious cause and damage from equipment installers.
Somewhere as small as Burnham Green, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when you book.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What happens on the day
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Cottages and farmhouses around Burnham Green frequently 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.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
How to prepare
- If the roof is shared, arrange access with whoever manages the building
- Keep pets inside or away from the areas we are looking at
- Have any paperwork from past roof work to hand

What else we do in Burnham Green
When to book a survey in Burnham Green
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
Typical things we’re asked to look at include:
- Damp inside with no sign on the roof
- A flat roof leak that cannot be traced
- Leaks that return after repairs
- Leaking laps in the waterproofing
Take a building like Monk's Walk School: a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Single-ply can be punctured by tools or fixings. Testing helps find them.
Your questions about electronic leak detection in Burnham Green
Does a conservation area affect roof work in Burnham Green?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Burnham Green?
Yes, Burnham Green is on our map. Villages and rural addresses get the same survey as a town house.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Can you survey in bad weather?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions aren’t right we will arrange another day with you.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
What’s the best way to book?
Simply call 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day.

Tips that help
You don’t need to be a roofer to help. Here’s what helps most:
- Do not let outlets block
- Act on new leaks promptly
- Share any drawings of the roof
- Consider ELD before paving or planting goes on
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
