Electronic leak detection in Cooper's Green: what you get
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs are not part of the report; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. If you’ve noticed stains far from any visible defect and waterproofing to test before it’s covered, we can find out what’s behind it, on flat roof membranes, liquid-applied waterproofing and roof terraces and balconies alike.
In a small place like Cooper's Green, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Your questions about electronic leak detection in Cooper's Green
Does a conservation area affect roof work in Cooper's Green?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Are flat-roofed garages and porches in Cooper's Green worth including?
Usually, yes: let us know about it as you book so the visit can include it. Flat-roofed garages and porches are common in new towns like Hatfield, and older felt coverings may be near the end of their life.
How do I arrange electronic leak detection in Cooper's Green?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Tell us what you know about the roof and we will confirm suitability.
Which days do you carry out surveys?
We carry out surveys on weekdays and at weekends. To find a day that suits you, ring 07833 053749 or send us an email.
Does the weather affect the survey?
Light rain is typically fine; heavy rain and wind are different. Strong wind or heavy rain can make access unsafe and ground a drone, so we’d move the date with you.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Surveys for landlords and agents in Cooper's Green
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which helps when tenants work during the week.
Practical tips
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Share any drawings of the roof
- Act on new leaks promptly
- Find the breach before more patching
- Record dates and spots where water appears
Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Electronic leak detection around Cooper's Green
Hatfield House, about 2.7 miles east, is one of the historic houses in the wider area around Cooper's Green. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Hatfield, which Cooper's Green is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
For site and facilities teams at buildings such as Howe Dell Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Hatfield station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you run a business near The Maltings, the flat roofs over shops and commercial units are worth checking before a leak, not after.

How it works
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photos go into the written report. The visit typically takes as long as needed for the size of the roof and how it’s built, which we set out in the quote. Cottages and farmhouses around Cooper's Green often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- First, you tell us about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Check pets are kept safely away
- Check we can get to the back of the property
- Agree roof access with the managing agent if it’s shared
How to book
Booking is simple: just phone 07833 053749 or email us, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.
Advice
What a survey costs
Prices always include VAT. The things that change the price are:
- Whether thermal imaging or a drone is needed
- House, block, shop or office
- The number of roofs, including extensions and garages
- Roof area
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the price for the job before booking.
What we need to know
Here’s what helps us most when you contact us:
- Where the property is, with the postcode
- The style of property, from a terrace to a block
- Any marks or damp showing indoors
- When you need the report by
If you have photos of the roof, send them over. Take them safely from the ground or a window. To get started, phone 07833 053749 or use the contact form.
Leave it or get it looked at?
Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. For an older or listed building in a place like Cooper's Green, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
