How electronic leak detection works in Berkhamsted
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. If you’ve noticed leaks through a flat roof with no obvious cause and leaks at pipes, outlets or fixings, we can find out what’s behind it.
Houses around a town like Berkhamsted frequently have a flat roof somewhere, over an extension, garage, porch or dormer. Older ones are often felt, which frequently lasts around 15–20 years, while newer ones may be EPDM rubber or GRP fibreglass. The usual warning signs are standing water, splits and edges coming away. Standing water days after rain frequently shows a flat roof needs attention.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Electronic leak detection in Berkhamsted: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Cholesbury Manor House, about 3.5 miles west, show how far back building in the area around Berkhamsted goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Landlords with a home close to Berkhamsted station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Anyone responsible for a site like St Thomas More Roman Catholic Voluntary Aided Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to Church of All Saints: the joins between later flat roofs and the old walls are where problems usually start.

Should I look at the roof myself first?
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Why act early in Berkhamsted
Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. In a family home in Berkhamsted, a small roof fault lets water into places you can’t see, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
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. We quote electronic leak detection for each roof, as the method and time depend on the roof.

FAQs for Berkhamsted
Do you cover Berkhamsted?
Yes. We work right across London and the South East, and Berkhamsted is part of that. You can phone 07833 053749 or use the contact form with the address and a few details.
Does a conservation area affect roof work in Berkhamsted?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How soon will I get the report?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What’s in the report?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
Is this a RICS survey?
No. This is a survey of the roof only, so it’s not a RICS Level 2 or Level 3 survey. Many buyers have both.
Does the weather affect the survey?
It depends on the weather and the survey. High wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Useful tips for Berkhamsted property owners
From years of surveys, a few habits stand out as worth the effort:
- Stay off the flat roof unless needed
- Record dates and spots where water appears
- Find the breach before more patching
- Clear flat roof outlets regularly
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Consider testing a new membrane before it’s covered. It’s easier to find holes before more layers are added.

What else we do in Berkhamsted
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. A typical visit in Berkhamsted begins with the street side of the roof and then moves round the building. The back garden is often where extensions, dormers and rear slopes are best seen, so unlocked gates help. Then, if it can be reached safely, we look in the loft.
- We agree the area to be tested.
- We get the roof ready for testing.
