Electronic leak detection in Foster Street
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We survey green roofs, single-ply roofs and roof terraces and balconies, and the problems we are asked to look at most are new roofs to check before paving or planting and damage from equipment installers.
In a village or hamlet like Foster Street, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: 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 as you book.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that’s said too.

Flat and commercial roofs around Foster Street
Weatherboarded walls and clay tile roofs are typical of older Essex buildings, alongside plenty of post-war and newer estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Foster Street is part of Harlow, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Many of those flat roofs have been re-covered over the years, and some may still have older felt.
If you look after a building such as Henry Moore 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 Harlow Mill station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Foster Street is about 2 miles east of Harlow, in Essex. Whether the building in Foster Street is a house, a flat or a commercial unit, the roof can be surveyed. Across Essex, we cover Foster Street. You can also see our page for Chelmsford.

Your questions about electronic leak detection in Foster Street
How do I find out if my home in Foster Street is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Should a flat-roofed garage or porch in Foster Street be checked too?
Yes, if you’d like it included, mention it when you book. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
Is Foster Street in your area?
Yes. We survey roofs in Foster Street and the rest of Essex, as part of our work across London and South East England. To book, phone 07833 053749 or send us an email.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
Do you look in the roof space?
Normally, if there is one and it can be reached safely. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we’ll agree the details when you book.
Honest limits
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Fixing the holes we find
- Build-ups without a suitable layer below
- Moisture spread under the membrane

Signs you need electronic leak detection in Foster Street
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
People usually book a survey after spotting one of these:
- Failed seams and laps
- Water coming in under a flat roof
- Leaks showing away from the breach
- Leaks at pipes, outlets or fixings
The streets around a church like Church of All Saints are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking.
Questions to ask before you book
- Is there a chance to talk the report through?
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- What the report includes, and whether it has photos
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. The main factors are:
- Any need for thermal images or a drone flight
- How many separate roofs there are, such as extensions, dormers and garages
- How complicated the roof is, with its valleys, chimneys and parapets
- The type of building, from a house to a block or an office
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
We will normally ask about:
- The type of building and roof, like pitched or flat
- The property’s address and postcode
- The reason for the survey, such as buying, a leak or storm damage
- Access details, such as a loft hatch or a shared roof
Most bookings start with a short call: ring 07833 053749 or email us. The price is agreed before a date is set.
Why act early in Foster Street
Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. Older cottages and farmhouses around Foster Street can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

How it works
We will ask a few questions first, like when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Foster Street, 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 agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Check we can get to the back of the property
- Tell us about any leaks, stains or damp patches you know of
- Move anything stored under the loft hatch
Getting a price
Every survey is priced before it’s booked, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or use the contact form.
