About our electronic leak detection in Sandford St Martin
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. We test and report and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. We are often asked to look into new membranes needing a check before handover and stains far from any visible defect, across green roofs, liquid-applied waterproofing and commercial flat roofs.
Some older homes in villages like Sandford St Martin are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Sandford St Martin: your questions answered
How do I find out if my home in Sandford St Martin is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Will you come out to Sandford St Martin?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route as you book.
What happens after the survey?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You’ll know which method we plan to use before we start.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use so we check the roof first.
Do you look in the roof space?
Usually, if there is one and it can be reached safely. The roof space can show things the outside can’t, like damp timbers, staining or daylight.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. A breach lets the current through, which shows us where the hole is.
What happens on the day
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes a length of time set by the roof’s area and construction, which we set out in the quote. Rural addresses near Sandford St Martin 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. After that, the survey runs as it would anywhere.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- 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
- Move anything stored under the loft hatch
- Gather any invoices or paperwork from past roof work
- Agree roof access with the managing agent if it is shared

Related advice
What electronic leak detection looks like in Sandford St Martin
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.
If you own a rental within reach of Heyford station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark such as Church of St Martin, the joins between later flat roofs and the old walls are where problems usually start.

Why it’s worth a survey now in Sandford St Martin
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Where a roof is exposed, as many are in small places like Sandford St Martin, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.

Read how roof surveys are priced and what we found on two real jobs.
What affects the price in Sandford St Martin
Prices vary from roof to roof, for these reasons:
- Height and safe access
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
You do not need to know any roofing terms. Just tell us:
- Anything about access we should know
- Where water is showing inside, if it is
- What kind of property and roof it is
- Your postcode, so we can check access and travel
Getting a price is simple: just phone 07833 053749 or use the contact form, let us know about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Use boards when working on the roof
- Don’t leave water getting in
- Find the breach before more patching
- Keep outlets clear of debris
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
Different roofs, different checks
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
