Electronic leak detection in Picketts Lock, Greater London
Find out the condition of the flat roof membrane at your property in Picketts Lock from an independent roof surveyor. We visit on weekdays and at weekends.
- Leaks through a covered membrane
- A flat roof leak that can’t be traced
- Holes left by work on the roof
What a survey costs
What a survey costs depends on the time and equipment it needs. The main factors are:
- The size of the roof
- Building height and the viewpoints available
- If the survey needs thermal imaging or a drone
- House, block, shop or office
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
What we need to know
These details help when you get in touch:
- How the loft is reached, if there is one
- What made you get in touch
- Where the property is, with the postcode
- Photos of the roof, taken safely from ground level or a window
We survey roofs on any day of the week. To arrange a day that suits you, call 07833 053749 or email us with the address and the days you’d prefer.
About our electronic leak detection in Picketts Lock
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. We survey roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs, and people most frequently book us about a flat roof leak that can’t be traced and damp inside with no sign on the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Picketts Lock, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

What we look for on each type of roof

Green roofs and ballasted roofs cover the waterproofing. Testing may still be possible, depending on the build-up.
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.

Why it is worth a survey now in Picketts Lock
Repeated call-outs for the same leak add up. A report showing the breach points gives your roofer a clear target. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What electronic leak detection looks like in Picketts Lock
With Bruce Castle about 2.6 miles south-west, Picketts Lock sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you run a business near Edmonton Green Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Parking in Picketts Lock, as in most of London, takes a little planning: tell us about permits, visitor bays or off-street space as you book. The streets around a church like All Saints' Church are often among the oldest in a place, and if you own one of the older houses nearby, the joins between later flat roofs and the old walls are where problems normally start.

What you can safely check yourself
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
How it works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take a length of time set by the membrane area and the build-up, which we set out in the quote. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Let us know where we can park nearby
- Check the loft hatch can be reached
- Find any records of previous roof work
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or send us an email whenever suits you.
Advice
Your questions about electronic leak detection in Picketts Lock
Is my home in Picketts Lock listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will parking be an issue for a roof survey in Picketts Lock?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
How do I book a survey in Picketts Lock?
To book, call 07833 053749 or drop us an email and let us know the address and what you’d like to know. We’ll confirm the price and find a day that suits.
Does someone need to be in?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
Will you check the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Is this an asbestos survey?
No. We don’t sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
What we cannot see
Before you book, it’s worth knowing what a survey won’t do:
- Leaks from walls, copings or rooflights
- Fixing the holes we find
- How wet the insulation is
