Electronic leak detection in Sewards End
A leak in a flat roof frequently shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly and locates the breach. It is testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you are worried about leaks showing away from the breach and leaks through a flat roof with no obvious cause, we can find out what’s behind it.
Older buildings in small places like Sewards End may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

DIY checks: what’s safe
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Honest limits
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Leaks from plumbing or windows
- The extent of water in the insulation
- Repairing the breaches (that’s for your roofer)
If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey before booking. The full list of what we check.
Roof types and parts we check
- Green roofs
- Flat roof membranes
- Roof terraces and balconies
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
Before and after the survey
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Clear flat roof outlets regularly
- Test new membranes before covering them
- Note where leaks show inside and when
- Avoid repeated repairs without finding the cause
If we think the leak is not coming through the membrane, the report says so, with a suggestion of what to check next.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What electronic leak detection looks like in Sewards End
In Essex, older buildings are often clay-tiled, many with weatherboarding, while many towns grew with post-war and newer estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Audley End House, about 2.7 miles west, show how far back building in the area around Sewards End goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
For landlords with property near Audley End station, the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church such as St James' Church are often among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you look after a building such as Saffron Walden County High School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Questions from Sewards End
Does a conservation area affect roof work in Sewards End?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Will you come out to Sewards End?
Yes, Sewards End is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Can you test a green or ballasted roof?
On some roofs, yes. Covered roofs limit the methods we can use, so we check the build-up first.
Does electronic leak detection work on all membranes?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll check whether ELD will work.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
What does the report include?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
How much does electronic leak detection cost?
Each roof is quoted on its size and build-up. Send us details of the roof, and ring 07833 053749 or send us an email for a quote.

The survey, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Sewards End can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- First, you let us know about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Find any records of previous roof work
- Let us know about parking near the property
- Buyers: confirm access with the estate agent or seller
