Electronic leak detection in Well Hall: what you get
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. We don’t estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a written report with photos. We survey roof terraces and balconies, commercial flat roofs and green roofs, and people most often book us about stains far from any visible defect and holes left by work on the roof.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Well Hall, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

How the survey changes by roof type
Single-ply membranes
ELD frequently works on single-ply membranes, depending on the type and build-up.
Inverted and paved roofs
If the build-up rules out ELD, we’ll say so.
Local flat roofs in Well Hall
Eltham Palace, about 0.7 miles south, is one of the historic houses in the wider area around Well Hall. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you own a rental within reach of Eltham station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you live in an older home near St Barnabas, flat-roofed rear additions and dormers added over the years are worth checking. Shop and office owners around Lewisham Shopping Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Questions from Well Hall
Does a conservation area affect roof work in Well Hall?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is parking a problem for a survey in Well Hall?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Do you survey roofs on blocks of flats?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
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 my roof suitable for ELD?
ELD doesn’t suit every roof. Certain membranes are conductive and some roofs lack the layer the test needs. If your roof won’t work, we will say so before testing.
What does the report include?
You get our findings in writing, part by part, with photos. Points are put with the most urgent first where relevant.
Do you cover Well Hall for electronic leak detection?
Yes. We cover Well Hall and the rest of Greater London, as part of our work across London and South East England. To book, call 07833 053749 or send us an email.
Can I check my roof myself?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in.
Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Check new waterproofing before handover
- Record dates and spots where water appears
- Have roof specifications to hand
- Find the breach before more patching
Wet insulation may need attention after a leak. That’s something to discuss with your roofer, and moisture readings can help.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
How it works
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Surveys in Well Hall can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Keep pets inside or away from the areas we are looking at
- Unlock side gates and any roof access doors
- Find any records of previous roof work
