The survey, step by step
The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit typically takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting. In Bankside, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Tell us about parking before the day
- Have any questions written down, so nothing gets missed

Electronic leak detection for homes and businesses in Bankside
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. We will say if ELD won’t work on your roof 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 cannot give results. Common reasons to book are leaks showing away from the breach and holes around roof penetrations, across roof terraces and balconies, single-ply roofs and liquid-applied waterproofing.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Bankside shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report is written in plain words, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible.

Before and after the survey
Nothing here needs a ladder. Our suggestions:
- Do not keep patching the same spot
- Keep foot traffic on flat roofs to a minimum
- Check new waterproofing before handover
- Keep outlets clear of debris
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.

Your questions about electronic leak detection in Bankside
Does a conservation area affect roof work in Bankside?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you look at commercial flat roofs near Bankside, such as hotels?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
What do I do with the report?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report. We will recommend an engineer if we see signs that call for one.
What’s the best way to book?
It’s easiest to ring 07833 053749 or email us. Let us know the address and a little about the roof, and we’ll suggest the right survey. Surveys run seven days a week.

Why act early in Bankside
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Any roof job in Bankside means planning around parking, neighbours and access. That is a good reason to find problems early, while there’s time to plan.
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. Electronic leak detection is quoted for your roof, because the method depends on the roof.
