Electronic leak detection in Bowlhead Green: what you get
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use and parts may need to be lifted. We’ll discuss it with you when we quote. Any details of the build-up help, as they show what lies beneath the surface. We will tell you if the roof cannot be tested. If you’ve noticed breaches around outlets and penetrations and failed seams and laps, we can find out what’s behind it, on flat roof membranes, single-ply roofs and roof terraces and balconies alike.
Flat roofs on exposed homes in small places like Bowlhead Green 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.
Where we can’t see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Useful tips for Bowlhead Green property owners
Most of what helps is simple and safe from the ground. Our suggestions:
- Check trades protect the waterproofing
- Find the breach before more patching
- Check new waterproofing before handover
- Have roof specifications to hand
If anything in the report isn’t clear, ask us. We’ll explain what was found and what it means.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
Common roof problems in Bowlhead Green
Repeated leaks after repairs suggest the real breach hasn’t been found. Electronic testing helps pinpoint it.
Problems we come across often include:
- Leaks through a covered membrane
- Failed seams and laps
- Punctures from foot traffic or tools
- Waterproofing to test before it is covered
Landlords with a home close to Witley station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- What happens after the report arrives
- Which parts of the roof they’ll actually see
- Will the report include photos?
- Whether the price includes VAT
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
What you cannot do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in.
How the survey works
Every roof is different, but as a rough guide the survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. Older roofs in small places like Bowlhead Green can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- If you are buying, check with the agent that we can get in
- Clear the way to the loft hatch
- Mention any parking restrictions on your street
How to book
If you’re buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you are ready.

What electronic leak detection does not cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Repairing the breaches (that’s for your roofer)
- Some conductive membranes
- How wet the insulation is
If in doubt, ring 07833 053749 or drop us an email and we’ll point you to the right survey before you book. What our survey covers.
What we check
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Roof terraces and balconies
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client.
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Tell us about it as you book and we will plan the survey around it.
Questions from Bowlhead Green
Do you cover Bowlhead Green?
We do. The survey and report are the same in Bowlhead Green as anywhere else.
Will you come out to Bowlhead Green?
We do. A small place gets exactly the same survey as a big one.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use so we check the roof first.
How long will testing take?
Testing usually takes a length of time set by the roof’s area and construction, which we’ll explain when we quote.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when booking.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too.

What electronic leak detection looks like in Bowlhead Green
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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
If you live in an older home near Church of St Michael and All Angels, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
