Chignall St James questions
Is Chignall St James in the area you cover?
Yes. We work right across London and South East England, and Chignall St James is part of that. You can call 07833 053749 or email us with the address and a few details.
Will you come out to Chignall St James?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you look in the roof space?
If there’s a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Do you climb onto every roof?
Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and the report notes anything we couldn’t see.
Can every flat roof be tested?
That depends on the roof’s membrane and layers. Let us know what you know about the roof and we’ll confirm suitability.
Electronic leak detection for homes and businesses in Chignall St James
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 is a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a report with photographs of each breach found. We survey flat roof membranes, commercial flat roofs and single-ply roofs, and the problems we’re asked to look at most are new membranes needing a check before handover and failed seams and laps.
Older buildings in small places like Chignall St James may be listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later.

What happens on the day
Once we’ve finished looking, we write up our findings in a report with photos, emailed to you. As for time on site, most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Chignall St James, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.

- We check whether the membrane and build-up suit ELD.

What affects the cost of electronic leak detection
Prices vary from roof to roof, and it comes down to:
- How big the roof is
- The shape of the roof and its details
- Any need for thermal images or a drone flight
- The height of the building and how the roof can be seen safely
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.
Helping us price your survey
Some details help us suggest the right survey and price. When you contact us, let us know:
- Where the property is, with the postcode
- The style of property, from a terrace to a block
- Any stains, drips or damp patches you’ve seen indoors
- What made you get in touch
To arrange a survey, call 07833 053749 or send us an email and tell us the address and what’s prompted the survey. We will confirm the price before you book.
Different roofs, different checks
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We will say if the test won’t work.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. Whether ELD suits them depends on the build-up.
Flat and commercial roofs around Chignall St James
About 3.5 miles south lies Hylands, a reminder of how long the area around Chignall St James has been built on. If yours is one of the older homes, 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. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and a good many post-war and modern estates besides. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you let a flat or house near Chelmsford station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for instance near Bond Street Chelmsford, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building such as Newlands Spring Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Why get it checked now?

Can I check my roof myself?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
