Electronic leak detection in North Lee: what you get
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we will use. If neither method suits your roof, we will tell you before any testing starts. We survey flat roof membranes, green roofs and commercial flat roofs, and people most frequently book us about leaks through a covered membrane and gaps at membrane joints.
In a village or hamlet like North Lee, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them as you book.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Flat and commercial roofs around North Lee
Some villages in Buckinghamshire still have thatched roofs. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council.
For businesses in and around places like Friars Square, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Anyone responsible for a site like Stoke Mandeville Combined School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Stoke Mandeville station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

FAQs for North Lee
Is North Lee in the area you cover?
Yes, North Lee is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How do I find out if my home in North Lee is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
When does the report arrive?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Is the repair part of the test?
No, our part is finding the breaches. The report gives your roofer the locations.
Will you walk on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where it applies, and the report records anything we couldn’t see.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. We will tell you if yours is not suitable before testing.
Practical tips
Over many surveys, some simple habits stand out:
- Limit access to the roof
- Act on new leaks promptly
- Clear flat roof outlets regularly
- Use boards when working on the roof
Questions about the results are welcome. We’ll explain what was found and what it means.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
The survey, step by step
We work from the outside in: outside views come first, then the roof space if there is safe access. All told, expect as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Rural addresses near North Lee can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Have any paperwork from past roof work to hand
- Buyers: confirm access with the estate agent or seller
- Check pets are kept safely away
Book a survey
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or send us an email.
