How electronic leak detection works in Summerstown
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. We survey liquid-applied waterproofing, roof terraces and balconies and single-ply roofs, and the problems we’re asked to look at most are leaking laps in the waterproofing and holes around roof penetrations.
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 Summerstown shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Roof by roof
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check this first.
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Don’t let outlets block
- Test new membranes before covering them
- Record dates and spots where water appears
- Find the breach before more patching
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Landlord and commercial surveys in Summerstown
Letting agents can arrange access with tenants. We survey on any day of the week, which helps when tenants work during the week.
Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.
What affects the price in Summerstown
To price your survey, we check:
- How big the roof is
- How complicated the roof is, with its valleys, chimneys and parapets
- House, block, shop or office
- If the survey needs 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 price for your roof before booking.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, it helps to mention:
- Photos of the roof, taken safely from ground level or a window
- The type of building and roof, such as pitched or flat
- The reason for the survey, such as buying, a leak or storm damage
- Where any leaks, stains or damp patches show inside
We confirm the exact price before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or drop us an email.
What electronic leak detection looks like in Summerstown
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Summerstown is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses like Southside House, about 2.4 miles south-west, show how far back building in the area around Summerstown goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
For a London address like Summerstown, it helps to know about controlled parking before the day. For businesses in and around places such as Southside Wandsworth, flat roofs over shops and units are easy to forget until water comes through a ceiling. For site and facilities teams at buildings such as Burntwood School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Other services in Summerstown
Leave it or get it looked at?
ELD before paving, ballast or planting goes on is simpler. Once layers are added, finding a breach is harder. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

FAQs for Summerstown
Is my home in Summerstown listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Is parking a problem for a survey in Summerstown?
It rarely stops a survey, but it’s worth planning. Let us know what parking is available nearby, and the visit is planned around it.
How long will testing take?
It typically takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Just say which days work for you.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
Does the report include photographs?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We will tell you if yours isn’t suitable before testing.
How the survey works
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. The survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- 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.
How to prepare
- Leave side gates unlocked
- Check the loft hatch can be reached
- Keep pets in another room
