Chelmsford Electronic Leak Detection
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Chelmsford and across Essex, with plain-English findings.
- New roofs to check before paving or planting
- Damage from equipment installers
- Breaches around outlets and penetrations
Electronic leak detection for homes and businesses in Chelmsford
Our ELD report shows where each breach was found, with photos. Your roofer can then repair those points instead of hunting for the leak. Repair costs are not part of the report; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a report with photographs. We survey roof terraces and balconies, single-ply roofs and green roofs, and the problems we are asked to look at most are breaches around outlets and penetrations and waterproofing to test before it’s covered.
Blocks of flats in places the size of Chelmsford typically have a shared flat roof, which managing agents, residents’ companies or owners have to keep watertight. Leaks into top-floor flats are usually where trouble shows first. The earlier the cause is found, the less damage it does. Tell us who manages the building, as access to a shared roof has to be arranged.
Where we cannot see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Features like valleys, chimneys, dormers and parapets
- Roof area
- The number of roofs, including extensions and garages
- Whether it is a home or a commercial building
To find out what your survey will cost, ring 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.
Booking your survey
When you call or email, these details help:
- What made you get in touch
- The address and postcode of the property
- Where water is showing inside, if it is
- The style of property, from a terrace to a block
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, ring 07833 053749 or use the contact form.
Tips from our surveys
Most of what helps is simple and safe from ground level. Our suggestions:
- Check trades protect the waterproofing
- Do not leave water getting in
- Clear flat roof outlets regularly
- Find the breach before more patching
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Keep people off the flat roof unless they need to be there. Feet and dropped tools are a common cause of holes.
What electronic leak detection looks like in Chelmsford
About 2.8 miles south-west lies Hylands, a reminder of how long the area around Chelmsford has been built on. 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 the council can say whether a home is in a conservation area. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and lots of post-war and modern estates besides. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you look after a building such as Trinity Road Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For businesses in and around places such as Bond Street Chelmsford, the flat roofs over shops and commercial units are worth checking before a leak, not after. If you live in an older home near Church of the Holy Trinity, the joins between later flat roofs and the old walls are where problems normally start.
Chelmsford is about 30 miles north-east of London, in Essex. If you’re in Chelmsford, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Across Essex, we cover Chelmsford and the places around it.

FAQs for Chelmsford
Do you carry out roof surveys in Chelmsford?
Yes. We survey roofs across London and South East England, and Chelmsford is part of that. You can phone 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.
Is my home in Chelmsford listed or in a conservation area?
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 repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
What’s the price of ELD?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, ring 07833 053749 or email us.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
Do you climb onto every roof?
Only if it’s safe. We check everything that can be seen safely: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. The report says if anything couldn’t be seen.
Honest limits
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Moisture spread under the membrane
- Fixing the holes we find
- Water entering through details rather than the membrane
If in doubt, ring 07833 053749 or send us an email and we’ll point you to the right survey. What our survey covers.
Roofs we survey in Chelmsford
- Roof terraces and balconies
- Flat roof membranes
- Single-ply roofs
- Commercial flat roofs
- Liquid-applied waterproofing
- Green roofs
Why get it checked now?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. In a place with as many rented homes as Chelmsford, small roof faults often turn into tenant complaints. Spotting it early is easier than dealing with water damage in an occupied home.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Why book us in Chelmsford
- 20+ years’ experience
- Photographs and a written report every time
- Visits on any day of the week
- An independent view of the roof
What happens on the day
We check the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit usually takes a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. For a commercial building or block in Chelmsford, roof access is agreed with whoever manages it before the visit. At home, it’s useful to clear a route to the loft and point out any stains or leaks. The written report follows, with photos.
- You let us know about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Getting ready for the survey
- Find any records of previous roof work
- Move anything stored under the loft hatch
- For flats, check roof access has been agreed
