DIY checks: what’s safe
It’s useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book and it will help the survey.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
About our electronic leak detection in Mottingham
ELD can be carried out in more than one way. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. If neither method suits your roof, we will tell you at the outset. Common reasons to book are damage from equipment installers and new membranes needing a check before handover, on single-ply roofs, flat roof membranes and roof terraces and balconies.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Mottingham, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Common roof problems in Mottingham
Joints and laps in a membrane can fail over time. Small openings at laps can leak for months before it shows.
We are often asked to look at:
- Repairs that haven’t stopped the leak
- Damp inside with no sign on the roof
- Holes around roof penetrations
- Holes left by work on the roof
If you live in an older home near Jubilee International Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
What to check before booking
- Which parts of the roof they’ll actually see
- Whether the price includes VAT
- What’s outside the scope of the survey
- Is there a chance to talk the report through?
How the survey changes by roof type
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will say if the test won’t work.
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.

Common questions in Mottingham
Does a conservation area affect roof work in Mottingham?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Will parking be an issue for a roof survey in Mottingham?
Typically it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Do you climb onto every roof?
Only where it is safe to do so. We inspect what can be seen safely: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. Anything we cannot see is noted in the report.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
Is Mottingham in your area?
Yes. We survey roofs across London and South East England, Mottingham included.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Electronic leak detection in Mottingham: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 1.1 miles north-east lies Eltham Palace, a reminder of how long the area around Mottingham has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
Shop and office owners around The Glades may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts. For a London address like Mottingham, it helps to know about controlled parking before the day.
Mottingham is about 1 mile south-west of Eltham, in Greater London. Mottingham is part of the area we cover and the surrounding area as part of our work across London and South East England. Our Greater London coverage includes Mottingham. London is in our area too.
We survey roofs across the SE9, SE12 and BR1 postcode area for electronic leak detection and the streets around it. Local streets include Horley Road, Dorset Road and Albert Road, and we cover them all. We also cover Chinbrook (1 mile south-west), Grove Park (1 mile west), Coldharbour (1 mile east), Middle Park (1 mile north) and Horn Park (1 mile north-west). Within a short drive, we also cover London (7 miles north-west), City of Westminster (10 miles north-west), Marylebone (10 miles north-west), Kensington (11 miles north-west), St Pancras (9 miles north-west) and Shoreditch (8 miles north-west).
Near you in Mottingham
Locally, jobs take us to homes and businesses close to Colfe's School, Chinbrook Meadows and Haberdashers' Aske's Knights Academy. The nearest railway station is Grove Park station, roughly 0.7 miles west of the centre. Nearby you will also find Greenwich Castle (3.5 miles north-west) and Prefab Museum (1.7 miles west). Not far away are Summer Hill and The Tarn.
What happens on the day
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when booking.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- 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.
Before the survey
- Tell us where we can park nearby
- Keep pets out of the way during the survey
- Gather any invoices or paperwork from past roof work
