Electronic leak detection for homes and businesses in Woolwich
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. If testing isn’t possible, we will say so. If you’ve noticed leaks at pipes, outlets or fixings and new membranes needing a check before handover, a survey will tell you what’s going on, on single-ply roofs, commercial flat roofs and liquid-applied waterproofing alike.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Woolwich, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
What you get is a clear record of the flat roof membrane on the day we saw it. It’s useful right away, and a good reference for later, such as when you want to compare after future work.

Electronic leak detection around Woolwich
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Woolwich has a long history of building, with Queen's House about 2.9 miles west. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Mulgrave Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Landlords with a home close to Woolwich Dockyard station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Woolwich is about 6 miles south-east of Leyton, in Greater London. Whether the building in Woolwich is a house, a flat or a commercial unit, we can survey the roof. Across Greater London, we cover Woolwich and the places around it. For surveys nearby, see our London page.

What affects the cost of electronic leak detection
When we price a survey, we consider:
- The use of thermal imaging or a drone
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, tell us:
- Dates you’re working to, like exchange
- How the loft is reached, if there is one
- What kind of property and roof it is
- What made you get in touch
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or use the contact form with the address and the days you’d prefer.
Can I check my roof myself?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
What happens if roof problems are left?
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.

When to book a survey in Woolwich
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
We’re often asked to look at:
- Breaches hidden under paving or planting
- Holes left by work on the roof
- New roofs to check before paving or planting
- Leaks at pipes, outlets or fixings
For businesses in and around places like Gallions Reach Shopping Park, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Questions to ask before you book
- What happens after the report arrives
- Whether VAT is added on top
- How long they’ve been surveying roofs
- What exactly goes into their report

How the survey works
On the day, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can be seen safely, from the ground, from windows, in the loft space and by drone where applicable. The survey usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In Woolwich, as in much of London, a good many properties are flats or terraces without 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. If the building has a managing agent or access rules, tell us when booking.
- 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.
- The report is sent for your roofer to act on.
How to prepare
- Gather any invoices or paperwork from past roof work
- If the roof is shared, arrange access with whoever manages the building
- Unlock side gates and any roof access doors

Advice
Questions from Woolwich
Do you cover Woolwich?
Yes. Our area covers London and South East England, and Woolwich is part of that. Just phone 07833 053749 or drop us an email and let us know about the property.
Will parking be an issue for a roof survey in Woolwich?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Can you find leaks on a covered flat roof?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We’ll discuss it before we quote.
Do you test for asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
What happens after the survey?
You receive the written report by email, with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
