How electronic leak detection works in Chenies
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. If you’ve noticed punctures from foot traffic or tools and gaps at membrane joints, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Chenies may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

What affects the cost of electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- Chimneys, valleys, parapets and other details
- Commercial roofs and larger buildings
- How tall the building is and how easy the roof is to see
- How many separate roofs there are, like extensions, dormers and garages
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.
Helping us price your survey
What helps most when you contact us:
- Access details, such as a loft hatch or a shared roof
- Where water is showing inside, if it is
- Pictures of the roof from a safe spot, if you have them
- Your postcode, so we can check access and travel
If you are buying, it helps to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.
DIY checks: what’s safe
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where it applies.

Local flat roofs in Chenies
Historic houses such as Chenies Manor House, about 0.2 miles south, show how far back building in the area around Chenies goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
Take a building like Chenies School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If yours is one of the older homes in the streets near Church of St Michael, flat-roofed rear additions and dormers added over the years are worth checking.

Your questions about electronic leak detection in Chenies
Do you carry out roof surveys in Chenies?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is Chenies within the area you cover?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you need to get into the loft?
Yes, where the survey calls for it and there is safe access. We look for staining, damp, daylight and signs of movement.
Is this an asbestos survey?
No. We do not sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
What if it rains on the day?
A survey can typically go ahead in light rain, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Does this replace a RICS home survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
What do I do with the report?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
What we are asked to look at in Chenies
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
Here are some of the things we see often:
- Leaks through a covered membrane
- Leaks that return after repairs
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
For landlords with property near Chalfont & Latimer station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book anyone
- Whether the inside of the roof is included
- What follow-up you get after the report
- What the report includes, and whether it has photos
- Whether any drone flown is registered with the CAA
Different roofs, different checks
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. ELD can help locate them on suitable roofs.
What happens on the day
We check the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In a small place like Chenies, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
- Check pets are kept safely away
How to book
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or drop us an email.
Related advice
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. In a place like Chenies, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
