Electronic leak detection in Box Hill, Surrey
Electronic leak detection to pinpoint holes in flat roof membranes in Box Hill, carried out by an experienced roof surveyor. You get a clear written report with photographs.
- New roofs to check before paving or planting
- Leaks through a covered membrane
- Damage from equipment installers
The survey, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. The visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Box Hill can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Before we arrive
- Dig out any old roof reports or invoices
- Let us know about parking near the property
- Jot down any questions you want answered

About our electronic leak detection in Box Hill
We carry out electronic leak detection on flat roofs in Box Hill and across London and the South East. Testing typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Electronic leak detection is quoted for your roof, because the method depends on the roof. The results come in a written report with photos. We’re often asked to look into new roofs to check before paving or planting and failed seams and laps, across single-ply roofs, green roofs and commercial flat roofs.
In a village or hamlet like Box Hill, flat roofs are normally 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. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when booking.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Can I check my roof myself?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Electronic leak detection around Box Hill
Polesden Lacey, about 3.9 miles west, is one of the historic houses in the wider area around Box Hill. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
The streets around a church like St. Andrew's Church are often among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to Betchworth station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Why get it checked now?
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out so attention can go to the right place. In a place like Box Hill, 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.

Signs you need electronic leak detection in Box Hill
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Signs worth acting on include:
- Punctures from foot traffic or tools
- Water coming in under a flat roof
- New roofs to check before paving or planting
- Failed seams and laps
If you look after a building like The Ashcombe School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Your questions about electronic leak detection in Box Hill
Is my home in Box Hill listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Will you come out to Box Hill?
We do. Villages and rural addresses get the same survey as a town house.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
How is ELD priced?
Each roof is quoted on its size and build-up. Let us know about the roof and where it leaks, and phone 07833 053749 or send us an email for a quote.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys across London and South East England.
What affects the cost of electronic leak detection
All our prices include VAT. The things that change the price are:
- Features like valleys, chimneys, dormers and parapets
- Commercial roofs and larger buildings
- Building height and the viewpoints available
- Any need for thermal images or a drone flight
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Booking your survey
A little information up front helps. It’s useful to include:
- Any deadline, like an exchange date
- Any photos you have, taken from the ground or a window
- What kind of property and roof it is
- Where water is showing inside, if it is
We confirm the price for your roof before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or email us.
What electronic leak detection does not cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Roofs whose membrane or build-up isn’t suitable
- Leaks from plumbing or windows
- The extent of water in the insulation
If in doubt, ring 07833 053749 or email us and we will point you to the right survey before booking. What our survey covers.
