About our electronic leak detection in Bullsmoor
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing isn’t possible, we will say so. If you are worried about new membranes needing a check before handover and repairs that haven’t stopped the leak, a survey will tell you what’s going on, on green roofs, commercial flat roofs and liquid-applied waterproofing alike.
In smaller places like Bullsmoor, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let lots of water into the room below. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Why it’s worth a survey now in Bullsmoor
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Blocked gutters on homes around Bullsmoor overflow and soak walls. Dealing with the cause is simple; drying out a wall is not.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

Different roofs, different checks
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible but it depends on the layers.
Liquid-applied waterproofing
Pinholes in a coating can let water through. ELD can help locate them on suitable roofs.
Practical tips
Here are a few things we’d tell any owner, before and after a survey:
- Find the breach before more patching
- Consider ELD before paving or planting goes on
- Do not let outlets block
- Don’t leave water getting in
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
The survey, step by step
Every roof is different, but as a rough guide the survey takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. If you have questions on the day, just ask. For a survey in Bullsmoor, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.

FAQs for Bullsmoor
Do you cover smaller places like Bullsmoor?

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, call 07833 053749 or send us an email.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
What insurance do you have?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Signs you need electronic leak detection in Bullsmoor
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Typical things we’re asked to look at include:
- Holes left by work on the roof
- Gaps at membrane joints
- A flat roof leak that cannot be traced
- Breaches around outlets and penetrations
For businesses in and around places such as Edmonton Green Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Choosing a roof surveyor
- Whether the loft is part of the inspection
- Whether you can ask questions once you have the report
- Whether VAT is added on top
- Which parts of the roof they’ll actually see
What electronic leak detection looks like in Bullsmoor
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Forty Hall about 1 mile south-west, Bullsmoor sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you live in an older home near St George's Church, the joins between later flat roofs and the old walls are where problems normally start. Anyone responsible for a site like Honilands Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
