Grafham Electronic Leak Detection
Electronic leak detection in Grafham, backed by more than 20 years’ experience. Every survey ends with a written report and photographs.

- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
Electronic leak detection in Grafham
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We don’t estimate repair costs; that is for your roofer to price. A retest after repairs can check the work if the build-up allows. You get a written report with photographs. We survey green roofs, single-ply roofs and commercial flat roofs, and people most frequently book us about leaks through a covered membrane and leaks at pipes, outlets or fixings.
In a village or hamlet like Grafham, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, and recommendations are put in order of urgency where relevant.

How it works
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photographs as we go and record our findings for the written report. It normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Older rural homes like those around Grafham 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, and anything we cannot see is noted.
- 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.
Preparing for the visit
- Dig out any old roof reports or invoices
- Buyers: confirm access with the estate agent or seller
- Leave side gates unlocked
Arrange a survey
A quick phone call is normally the easiest start: call 07833 053749 or send us an email. You will have a price before anything is arranged.

What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- Building height and the viewpoints available
- House, block, shop or office
- Extra roofs, like extensions, dormers or garages
- How complicated the roof is, with its valleys, chimneys and parapets
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What we need to know
Getting the details right at the start saves time. It helps to include:
- Access details, such as a loft hatch or a shared roof
- Any deadline, such as an exchange date
- Photos of the roof, taken safely from ground level or a window
- The reason for the survey, such as buying, a leak or storm damage
Getting a price is simple: just phone 07833 053749 or email us and give us a few details about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
FAQs for Grafham
Do you carry out roof surveys in Grafham?
We do. Every survey there gets the same written report with photos.
Does a conservation area affect roof work in Grafham?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Do you need to get into the loft?
If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible.
Can every flat roof be tested?
ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. If your roof will not work, we will say so at the start.
Does ELD work under paving or planting?
It can be possible, depending on the roof. What sits on the membrane affects the method, so we check the build-up first.
Should I look at the roof myself first?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Don’t let outlets block
- Test new membranes before covering them
- Keep foot traffic on flat roofs to a minimum
- Record dates and spots where water appears
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Honest limits
It’s a careful look at the flat roof membrane, not the whole story. The main limits are:
- Fixing the holes we find
- Areas we cannot reach or that can’t be tested
- Roofs whose membrane or build-up is not suitable

Flat roofs in Grafham
Many older homes in Surrey have handmade clay tiles and tile-hung 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. Chilworth Manor, about 3.8 miles north, is one of the historic houses in the wider area around Grafham. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you live in an older home near Church of St Andrew, the joins between later flat roofs and the old walls are where problems usually start. If you own a rental within reach of Chilworth station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Why act early in Grafham
Not every leak is in the membrane. ELD helps rule the membrane in or out so attention can go to the right place. In a small place like Grafham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.
