Electronic leak detection in Sandon: what you get
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We don’t estimate repair costs, so your roofer prices the work. 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 commercial flat roofs, flat roof membranes and single-ply roofs, and the problems we are asked to look at most are leaks under green or ballasted roofs and new roofs to check before paving or planting.
In a village or hamlet like Sandon, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Landlord and commercial surveys in Sandon
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
We survey roofs for landlords and agents as well as householders. The report gives you a dated record of the flat roof membrane, with photographs, useful for planning maintenance.
What we look for on each type of roof
Bituminous membranes
ELD is frequently possible on bituminous membranes though the layers below matter.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
Before and after the survey
A little preparation and a few simple habits help. Some pointers:
- Limit access to the roof
- Have roof specifications to hand
- Act on new leaks promptly
- Keep outlets clear of debris
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
Common roof problems in Sandon
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Here are some of the things we see frequently:
- Leaks showing away from the breach
- Failed seams and laps
- Leaks through a flat roof with no obvious cause
- Punctures from foot traffic or tools
Landlords with a home close to Chelmsford station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- What the report includes, and whether it has photos
- How long the report takes to arrive
- How long they’ve been surveying roofs
- Which viewpoints they use to see the roof

Common questions in Sandon
Will you come out to Sandon?
Yes, Sandon is covered. We survey roofs across London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Is my home in Sandon listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
What if it rains on the day?
A survey can usually go ahead in light rain. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions aren’t right we’ll arrange another day with you.
How is ELD priced?
Each roof is quoted on its size and build-up. Send us details of the roof, and ring 07833 053749 or use the contact form for a quote.
How long will testing take?
Testing usually takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting.
Does electronic leak detection work on all membranes?
ELD doesn’t suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof will not work, we’ll say so at the start.
Is the repair part of the test?
No. We test the membrane and report. The report shows where each breach is for your roofer to repair.
Local flat roofs in Sandon
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 1.4 miles east lies Danbury Place, a reminder of how long the area around Sandon has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
The streets around a church such as Church of St Andrew are frequently among the oldest in a place, and if your home is one of the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Take a building like The Sandon School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Sandon is about 2 miles south-east of Chelmsford, in Essex. Sandon gets the same service as everywhere else we work: a careful inspection, photographs and a written report. Our Essex coverage includes Sandon and the places around it.

What happens on the day
Time on site depends on the size and shape of the roof, but 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. In a small place like Sandon, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- 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.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Check the loft hatch can be reached
- Check pets are kept safely away

Related advice
Leave it or get it looked at?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
To find out what your survey will cost, ring 07833 053749 or send us an email and let us know about the roof. The price is agreed before a date is set.
