Electronic leak detection for homes and businesses in Upper Hartfield
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Tell us about your roof to find out more. We are often asked to look into damp inside with no sign on the roof and leaks that return after repairs, across roof terraces and balconies, green roofs and commercial flat roofs.
In a village or hamlet like Upper Hartfield, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Can I check my roof myself?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
Common questions in Upper Hartfield
Is Upper Hartfield within the area you cover?
Yes, Upper Hartfield is on our map. A small place gets exactly the same survey as a big one.
How do I find out if my home in Upper Hartfield is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Do you use drones?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, and 98% of customers are satisfied.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
How do you choose the testing method?
The roof decides the method. We will explain why when we quote.
What we can’t see
No survey can tell you everything, and it’s better to know them up front. Keep these in mind:
- Leaks from plumbing or windows
- Build-ups without a suitable layer below
- Sections we cannot safely access

Electronic leak detection around Upper Hartfield
About 1.9 miles north lies Bassetts Manor, a reminder of how long the area around Upper Hartfield has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you let a flat or house near Ashurst Kent station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Use boards when working on the roof
- Record dates and spots where water appears
- Find the breach before more patching
- Get leaks traced quickly
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Check contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
Roof by roof
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll say if the test won’t work.
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Upper Hartfield, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- 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.
- The report is sent for your roofer to act on.
Before the survey
- Have any questions written down, so nothing gets missed
- Check the loft hatch can be reached
- Let us know about parking near the property
Book a survey
Photos help, if you have them. Pictures from the ground or a window are fine, and please don’t climb up for a closer look. To send them or to book, call 07833 053749 or use the contact form.
Advice
When to book a survey in Upper Hartfield
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
People typically book a survey after spotting something like this:
- Gaps at membrane joints
- Leaks through a flat roof with no obvious cause
- New membranes needing a check before handover
- Breaches hidden under paving or planting
If your house is among the older ones in the streets near Holy Trinity Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Choosing a roof surveyor
- Which parts of the roof they’ll actually see
- Will the report include photos?
- Whether the inside of the roof is included
- What the survey won’t cover
