About our electronic leak detection in Dunsfold
ELD can be carried out in more than one way. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. 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’ll tell you at the outset. We survey single-ply roofs, flat roof membranes and green roofs, and people most frequently book us about gaps at membrane joints and punctures from foot traffic or tools.
Flat roofs on exposed homes in small places like Dunsfold take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. Most surveys take longer on a large roof than a small one, and the build-up of the roof makes a difference too. For a village or hamlet like Dunsfold, the journey is planned beforehand: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- 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.
How to prepare
- Keep pets inside or away from the areas we are looking at
- Point out any leaks or damp patches
- Move anything stored under the loft hatch

Tips that help
From years of surveys, a few habits stand out:
- Record dates and spots where water appears
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
- 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.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.

FAQs for Dunsfold
Do you cover Dunsfold?
Yes, Dunsfold is one of the places we work. The survey and report are the same in Dunsfold as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Dunsfold?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That is how we locate breaches you cannot see.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
How is ELD priced?
We quote electronic leak detection for each roof, as the method and time depend on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or email us.
Why it’s worth a survey now in Dunsfold
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.

What affects the cost of electronic leak detection
Prices vary from roof to roof, for these reasons:
- Height and safe access
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- House, block, shop or office
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
If you can, have these to hand when you get in touch:
- Whether there is a loft hatch, a shared roof or tricky access
- The style of property, from a terrace to a block
- What made you get in touch
- Any deadline, such as an exchange date
A quick phone call is normally the easiest start: call 07833 053749 or email us. You will have a price before anything is arranged.
What we’re asked to look at in Dunsfold
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny, but still let water through.
We’re frequently asked to look at:
- Holes around roof penetrations
- Breaches hidden under paving or planting
- Repairs that haven’t stopped the leak
- New roofs to check before paving or planting
If you let a flat or house near Witley station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book any roof surveyor
- What insurance they carry
- When you will get the report
- What’s outside the scope of the survey
- Whether the loft is part of the inspection
Surveys for landlords and agents in Dunsfold
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it as you book and we will plan the survey around it.
Flat and commercial roofs around Dunsfold
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. 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.
Take an older house close to Church of St Mary and All Saints: the joins between later flat roofs and the old walls are where problems normally start.
