How electronic leak detection works in Lower Bourne
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. We survey roof terraces and balconies, liquid-applied waterproofing and flat roof membranes, and people most often book us about new roofs to check before paving or planting and holes left by work on the roof.
Outbuildings, garden rooms and garages in places like Lower Bourne often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It’s worth mentioning them as you book, so the visit can include them. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

Electronic leak detection around Lower Bourne
The wider area around Lower Bourne has a long history of building, with Farnham Castle about 1.6 miles north. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to St Martin by the Green: the joins between later flat roofs and the old walls are where problems usually start. Take a building like Farnham College: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Lower Bourne is about 1 mile south of Farnham, in Surrey. Whether the building in Lower Bourne is a house, a flat or a commercial unit, we can survey the roof. Lower Bourne is one of the towns and villages in Surrey where we work. There is also a page for Guildford.

What a survey costs
Prices vary from roof to roof, for these reasons:
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
- House, block, shop or office
- Whether thermal imaging or a drone is needed
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
A little information up front helps. It helps to include:
- The type of building and roof, like pitched or flat
- Any photos you have, taken from ground level or a window
- Where any leaks, stains or damp patches show inside
- What made you get in touch
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, phone 07833 053749 or use the contact form.
Tips that help
A survey works best with a little help from you, before and after. Tips:
- Get leaks traced quickly
- Don’t keep patching the same spot
- Consider ELD before paving or planting goes on
- Share any drawings of the roof
Where the evidence points to walls, copings or rooflights, we will note it, with a suggestion of what to check next.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Common roof problems in Lower Bourne
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
These are some of the problems a survey can pick up:
- Leaking laps in the waterproofing
- Leaks showing away from the breach
- Patched roofs that still leak
- A flat roof leak that cannot be traced
For landlords with property near Farnham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Questions from Lower Bourne
Is my home in Lower Bourne listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a 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.
Do you cover Lower Bourne?
Yes, Lower Bourne is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Do you climb onto every roof?
Only where it’s safe to do so. We look at everything that can safely be seen: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Is the repair part of the test?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
What we do, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes more time on a big roof than a small one, with the construction of the roof playing a part too. For a survey in Lower Bourne, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Jot down any questions you want answered
- Note where any stains or damp appear
- Keep pets inside or away from the areas we’re looking at
