Electronic leak detection for homes and businesses in Great Parndon
There are different ELD methods. Low-voltage testing is normally done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. We will say if your roof doesn’t suit either method at the outset. We survey green roofs, single-ply roofs and flat roof membranes, and people most frequently book us about waterproofing to test before it’s covered and damp inside with no sign on the roof.
In smaller places like Great Parndon, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let lots of water into the room below. Knowing the covering and how it was laid tells you what to expect from it. Ponding, splits and lifting edges are the signs to look for from a window.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Signs you need electronic leak detection in Great Parndon
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
People normally book a survey when they’ve noticed one of these:
- Stains far from any visible defect
- New roofs to check before paving or planting
- Gaps at membrane joints
- A flat roof leak that cannot be traced
For an older house near a landmark like Church of St Mary the Virgin, the joins between later flat roofs and the old walls are where problems normally start.

Great Parndon questions
Are flat-roofed garages and porches in Great Parndon worth including?
Yes, if you’d like it included, mention it when booking. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Is Great Parndon within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, ring 07833 053749 or use the contact form.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
What does the report include?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What a survey costs
We confirm the exact price before you book. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- Any need for thermal images or a drone flight
- Whether it is a home or a commercial building
- The roof’s overall size
To find out what your survey will cost, ring 07833 053749 or email us with the address and some details. We will confirm the figure before booking.
Getting in touch
Before you get in touch, it helps to have:

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in.
Electronic leak detection around Great Parndon
Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, while many towns grew with post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
If you own a rental within reach of Harlow Town station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Jerounds Primary Academy: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

What this survey cannot tell you

- Roofs whose membrane or build-up isn’t suitable
- Parts of the roof covered by fixed equipment
- Leaks from walls, copings or rooflights
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we’ll tell you. What our survey covers.

Roof by roof
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
How it works
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, take photographs as we go and make notes for the report. Most visits take longer on a large roof than a small one, and the build-up of the roof makes a difference too. A visit to a smaller place like Great Parndon is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Show us where any leaks or stains appear
- Move anything stored under the loft hatch
- Let us know where we can park nearby
