Electronic Leak Detection in Blackmore
Electronic leak detection to pinpoint holes in flat roof membranes in Blackmore, carried out by an experienced roof surveyor. Every survey comes with a written report and photos.

Electronic leak detection in Blackmore: what you get
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We’ll point you to the likely next step. If you are worried about repairs that haven’t stopped the leak and new roofs to check before paving or planting, we can find out what’s behind it, whatever the roof.
Somewhere as small as Blackmore, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when you book.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Certain rubber membranes are conductive, which can rule out some methods. We will say if the test won’t work.
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
What electronic leak detection looks like in Blackmore
With Ingatestone Hall about 3.8 miles south-east, Blackmore sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Older buildings in Essex frequently have clay tiles and weatherboarding, with post-war and more recent estates making up much of the newer housing. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If yours is one of the older homes in the streets near Church of St Laurence, 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 Blackmore Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Ingatestone station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Useful tips for Blackmore property owners
A survey works best with a little help from you, before and after. Tips:
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Ask contractors to protect the membrane
- Do not let outlets block
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- How tall the building is and how easy the roof is to see
- Whether it’s a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- How big the roof is
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Helping us price your survey
Here’s what helps us most when you get in touch:
- Where any leaks, stains or damp patches show inside
- The style of property, from a terrace to a block
- Access details, like a loft hatch or a shared roof
- What’s prompted the survey
Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or drop us an email.

Common questions in Blackmore
Is Blackmore within the area you cover?
Yes, Blackmore is on our map. A small place gets exactly the same survey as a big one.
How do I find out if my home in Blackmore is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Will you walk on the roof?
Not unless it is safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
How do I book a survey in Blackmore?
Simply ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Will you repair the leak?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What we cannot see
It’s a careful look at the flat roof membrane, not the whole story. Its limits include:
- Water entering through details rather than the membrane
- Roofs whose membrane or build-up is not suitable
- Sections we can’t safely access
Not sure which survey suits your roof? You can call 07833 053749 or send us an email and we will tell you before you book. What our survey covers.
What we check
- Flat roof membranes
- Roof terraces and balconies
- Green roofs
- Liquid-applied waterproofing
- Commercial flat roofs
- Single-ply roofs
How it works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, from ground level, from windows, in the loft space and by drone where applicable. The survey normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Blackmore, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Make a note of anything you’d like us to look at
- Keep pets in another room
Booking a survey
If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.
