Electronic leak detection in Streatham Park: what you get
Our ELD testing covers flat roofs in Streatham Park and the rest of London and the South East. A visit usually takes a time that depends on the membrane area and the build-up, which we’ll explain when we quote. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a report with photographs. We survey commercial flat roofs, roof terraces and balconies and flat roof membranes, and common reasons people get in touch are damp inside with no sign on the roof and a flat roof leak that can’t be traced.
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. Which one is on a roof in Streatham Park shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

FAQs for Streatham Park
Is parking a problem for a survey in Streatham Park?
It can be, so it helps to let us know about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Do you carry out roof surveys in Streatham Park?
Yes. Our area covers London and the South East, and Streatham Park is part of that. Just phone 07833 053749 or send us an email and let us know about the property.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
What is electronic leak detection?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached so we can pinpoint it.
How long does electronic leak detection take?
Testing typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too.
Is it a structural engineer’s report?
No. Visible signs like deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Do you need to get into the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
Prices for electronic leak detection in Streatham Park
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- How tall the building is and how easy the roof is to see
- House, block, shop or office
- The shape of the roof and its details
- The use of thermal imaging or a drone
All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. We confirm the exact price before booking.
What to tell us when you contact us
You don’t need to know any roofing terms. Just let us know:
- Whether there is a loft hatch, a shared roof or tricky access
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from the ground or a window
- The style of property, from a terrace to a block
We confirm the price for your roof before you book, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, call 07833 053749 or drop us an email.
Places near Streatham Park
Also in Streatham Park
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Before and after the survey
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep foot traffic on flat roofs to a minimum
- Find the breach before more patching
- Clear flat roof outlets regularly
- Make sure trades protect the waterproofing
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
Local flat roofs in Streatham Park
Historic houses like Kingswood House, about 2.6 miles east, show how far back building in the area around Streatham Park goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Shop and office owners around Southside Wandsworth may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. Parking in Streatham Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier. For an older house near a landmark such as Parish Church of St Alban, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Streatham Park is about 1 mile west of Streatham, in Greater London. Roofs in Streatham Park get the same thorough look as anywhere else in Greater London. Streatham Park is one of the towns and villages in Greater London where we work for electronic leak detection.

How the survey changes by roof type
Bituminous membranes
Bitumen roofs can frequently be tested electronically though the layers below matter.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
What happens if roof problems are left?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In Streatham Park, as across London, an overflowing gutter soaks the wall below. A small blockage left for a few winters becomes a damp problem.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs 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
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, from ground level, from windows, in the roof space and by drone where applicable. The survey usually takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Have any questions written down, so nothing gets missed
- Agree roof access with the managing agent if it’s shared
- Keep pets inside or away from the areas we’re looking at
