Common questions in Upton
Do you carry out roof surveys in Upton?
Yes, Upton is one of the places we work. Every survey there gets the same written report with photographs.
Will parking be an issue for a roof survey in Upton?
Parking in Upton, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when booking.
Which days do you carry out surveys?
We carry out surveys on weekdays and at weekends. To arrange a date, ring 07833 053749 or email us.
Is it a structural engineer’s report?
No. We are experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Can you find leaks on a covered flat roof?
On some roofs, yes. What sits on the membrane affects the method so we check the roof first.
Does ELD include fixing the breach?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
Electronic leak detection for homes and businesses in Upton
Our ELD testing covers flat roofs in Upton and the rest of London and the South East. A visit usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a written report with photos. Common reasons to book are water coming in under a flat roof and damp inside with no sign on the roof, across green roofs, roof terraces and balconies and single-ply roofs.
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. For a building in Upton, access is agreed with whoever manages the roof before the visit. Plant bases, rooflights and cable entries are all places where water can get in.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely. Most surveys take a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Mention any parking restrictions on your street
- Check the loft hatch can be reached
Booking a survey
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we’ll ask about the building and what you need. You will have a price before anything is arranged.
Advice
Useful tips for Upton property owners
Over many surveys, some simple habits stand out:
- Check trades protect the waterproofing
- Find the breach before more patching
- Record dates and spots where water appears
- Check new waterproofing before handover
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
What electronic leak detection does not cover
It is a careful look at the flat roof membrane, not the whole story. The main limits are:
- Moisture spread under the membrane
- Roofs whose membrane or build-up isn’t suitable
- Repairing the breaches (that is for your roofer)
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we’ll tell you. The full list of what we check.

What electronic leak detection looks like in Upton
Historic houses such as Red House, about 0.3 miles south-west, show how far back building in the area around Upton goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Upton is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Upton is in London, so parking needs planning: let us know about parking bays, permits or a driveway as you book, as a space near the door cannot be promised. If you look after a shop, office or commercial unit, for example near Broadway Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Upton is about 1 mile east of Welling, in Greater London. In Upton, as across Greater London, every roof gets the same careful survey. We cover towns and villages across Greater London, large and small. London is in our area too.
Surveys in DA6, DA7 and DA16 work the same way as everywhere else we cover. Whether your property is on Lion Road, Upton Road and Freta Road or anywhere close by, we can survey it. We also cover Bexleyheath (1 mile east), Crook Log (1 mile west), Blendon (1 mile south-west), Bexley (1 mile south) and Welling (1 mile west). Larger places within reach include London (10 miles west), City of Westminster (13 miles west), Marylebone (13 miles west), Kensington (15 miles west), St Pancras (12 miles north-west) and Shoreditch (10 miles north-west).
What’s near Upton
We work in homes and buildings around St Catherine's Catholic School, Danson Park and Bexleyheath Academy. There’s a railway station in Upton itself: Bexleyheath station. Nearby you will also find Bexley Hospital (under half a mile south-west) and Broadway Shopping Centre (0.5 miles south-east). For a walk, there is Summer Hill and Wansunt Pit.
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.

Common roof problems in Upton
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Signs worth acting on include:
- Punctures from foot traffic or tools
- Leaks at pipes, outlets or fixings
- A flat roof leak that can’t be traced
- Breaches hidden under paving or planting
Landlords with a home close to Bexleyheath station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking any roof surveyor
- What insurance they carry
- Their report turnaround times
- How long they’ve been surveying roofs
- Whether any drone flown is registered with the CAA
How we price electronic leak detection
Prices always include VAT. What changes the price is:
- The type of building, from a house to a block or an office
- The height of the building and how the roof can safely be seen
- How big the roof is
- Any need for thermal images or a drone flight
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
