Electronic leak detection in Hastoe
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. We then send you the results in a written report. If you’ve noticed water coming in under a flat roof and repairs that haven’t stopped the leak, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Hastoe, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
Where we can’t see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Electronic leak detection around Hastoe
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 1.6 miles south-east lies Cholesbury Manor House, a reminder of how long the area around Hastoe has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Tring School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Tring station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take an older house close to Church of St Martha (Anglian Methodist): later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

The survey, step by step
The visit has one job: to see as much of the flat roof membrane as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It normally takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere as small as Hastoe, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
How to prepare
- Gather any invoices or paperwork from past roof work
- If you are buying, let the agent know when we’re coming
- Make a note of anything you’d like us to look at
How to book
To book a survey, call 07833 053749 or use the contact form and tell us the address and what’s prompted the survey. We will confirm the price before booking.
Advice
What affects the cost of electronic leak detection
The price reflects the time and kit the roof needs. The main factors are:
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- Height and safe access
- Whether thermal imaging or a drone is needed
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What to let us know when you get in touch
To price your survey accurately, we will ask about:
- Any stains, drips or damp patches you’ve seen indoors
- Pictures of the roof from a safe spot, if you have them
- Where the property is, with the postcode
- Access details, like a loft hatch or a shared roof
If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you are ready.
Different roofs, different checks
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Bituminous membranes
Bitumen roofs can frequently be tested electronically, depending on what’s below.
Useful tips for Hastoe property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Keep a note of leaks after rain
- Clear flat roof outlets regularly
- Do not leave water getting in
- Ask contractors to protect the membrane
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.
Hastoe questions
Is Hastoe within the area you cover?
Yes. Hastoe is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Does a conservation area affect roof work in Hastoe?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do I have to be there for the survey?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof will not work, we will say so at the start.
What insurance do you have?
We hold professional indemnity and public liability insurance.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Tell us which days suit you when you book.
How much time does ELD need?
Testing typically takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote.
What this survey can’t tell you
It’s useful to know what a survey will not do before booking:
- Moisture spread under the membrane
- Repairing the breaches (that is for your roofer)
- Leaks from plumbing or windows
If in doubt, call 07833 053749 or drop us an email and we’ll point you to the right survey before booking. What a survey covers and doesn’t.
