Electronic leak detection in Worth, West Sussex
Electronic leak detection in Worth from an independent, experienced roof surveyor. More than 20 years and over 5,000 surveys.
- Damp inside with no sign on the roof
- Patched roofs that still leak
- Breaches around outlets and penetrations
What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. In a smaller place like Worth, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Wind gets under it and lifts more, and water follows.
The cost of a survey depends on the roof: 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.

Electronic leak detection in Worth: what you get
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We survey commercial flat roofs, liquid-applied waterproofing and green roofs, and people most often book us about holes around roof penetrations and water coming in under a flat roof.
Flat roofs in smaller places like Worth can be more exposed, particularly where nothing shelters them, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report records the flat roof membrane as we found it on the day. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

How it works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. A visit to a smaller place like Worth is no different on the day: outside, inside and from any safe vantage point, in that order. It helps to show us anything you’ve already noticed.
- First, you tell us about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- For a flat or shared roof, check access with whoever owns or manages the building
- Note where any stains or damp appear

Flat roofs in Worth
Crawley, which Worth 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. Historic houses such as Gravetye Manor, about 4.2 miles south-east, show how far back building in the area around Worth goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you look after a building like Maidenbower Junior School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For an older house near a landmark such as St Nicholas' Church, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Three Bridges station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Worth is about 2 miles east of Crawley, in West Sussex. We carry out electronic leak detection in Worth for houses, flats, blocks and commercial buildings, with a written report and photographs every time. Our area takes in places right across West Sussex, from the larger towns to small villages.

Worth questions
Do you cover smaller places like Worth?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Does a conservation area affect roof work in Worth?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
What is electronic leak detection?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
What happens next?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Tell us about it when you book and we’ll plan the survey around it.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we look at the roof.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
