Electronic Leak Detection in Little Venice
Independent electronic leak detection in Little Venice. More than 5,000 surveys completed across London and South East England.
- Stains far from any visible defect
- Damage from equipment installers
- New roofs to check before paving or planting
Checking the roof from the ground
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Electronic leak detection for homes and businesses in Little Venice
Electronic leak detection works on many flat roof membranes, 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. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. We survey roof terraces and balconies, liquid-applied waterproofing and flat roof membranes, and common reasons people get in touch are a flat roof leak that can’t be traced and breaches around outlets and penetrations.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Little Venice, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

Tips that help
A little preparation and a few simple habits help. Our tips:
- Keep a note of leaks after rain
- Limit access to the roof
- Get leaks traced quickly
- Clear flat roof outlets regularly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
What happens on the day
A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from each safe vantage point, take photos as we go and record our findings for the written report. It typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Unlock side gates and any roof access doors
- Dig out any old roof reports or invoices
- For flats, make sure roof access has been agreed
Book a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you are ready.
Advice
Different roofs, different checks
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. ELD can locate them.
Your questions about electronic leak detection in Little Venice
Will parking be an issue for a roof survey in Little Venice?
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.
Do you cover commercial flat roofs around Little Venice?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
How much does electronic leak detection cost?
We quote electronic leak detection for each roof, as the method and time depend on the roof. The price depends on the roof’s size and build-up. For a quote, call 07833 053749 or email us.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
What insurance do you have?
We hold professional indemnity and public liability insurance.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access; we will agree the details when you book.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Honest limits
Every survey has limits, and it’s better to know them up front. Bear these in mind:
- Sections we cannot safely access
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that is for your roofer)

What affects the price in Little Venice
A few things affect what a survey costs:
- The number of roofs, including extensions and garages
- The shape of the roof and its details
- House, block, shop or office
- How big the roof is
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.
What to tell us when you get in touch
A little information up front helps. Please include:
- Pictures from the garden or a window, if you have them
- The address and postcode of the property
- Any stains, drips or damp patches you’ve seen indoors
- The kind of building and roof involved
If you have photos of the roof, send them over. Take them safely from ground level or a window. To send them or to book, ring 07833 053749 or drop us an email.
Local flat roofs in Little Venice
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Winfield House, about 1 mile north-east, is one of the historic houses in the wider area around Little Venice. 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.
Anyone responsible for a site like Ark Paddington Green Primary Academy will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For businesses in and around places like Kensington Arcade, flat roofs over shops and units are easy to forget until water comes through a ceiling. For hotels and guest houses around Little Venice, a roof problem found early is far less disruptive than one found by a guest.
