Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
About our electronic leak detection in Furzedown
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Let us know about your roof to find out more. Common reasons to book are water coming in under a flat roof and patched roofs that still leak, across roof terraces and balconies, flat roof membranes and commercial flat roofs.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in Furzedown, the flat roof is often a shared part of the building.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

What you can safely check yourself
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are frequently out of sight.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
When you need someone else
It is a careful look at the flat roof membrane, not the whole story. Its limits include:
- Roofs whose membrane or build-up is not suitable
- Sections we cannot safely access
- The extent of water in the insulation

Local flat roofs in Furzedown
Historic houses such as Kingswood House, about 2.9 miles east, show how far back building in the area around Furzedown goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. If your home in Furzedown is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you look after a shop, office or commercial unit, for instance near Southside Wandsworth, flat roofs over shops and units are easy to forget until water comes through a ceiling. The streets around a church like St Paul's Church are often among the oldest in a place, and if you own one of the older houses nearby, flat-roofed rear additions and dormers added over the years are worth checking. Controlled parking zones are common in London, so mention any permit rules for Furzedown, along with any off-street space.

FAQs for Furzedown
Will parking be an issue for a roof survey in Furzedown?
It depends on the street. If Furzedown has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Is my home in Furzedown listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Does electronic leak detection work on all membranes?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours isn’t suitable before testing.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. You’ll know roughly how long before we start.

Landlord and commercial surveys in Furzedown
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Letting agents can arrange access with tenants. We survey on weekdays and at weekends, which helps when tenants work during the week.
Why act early in Furzedown
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss where the roof suits it. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.

How it works
We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. The survey usually takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. For a visit in Furzedown, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at what can safely be seen from the ground, windows, the loft and, where it’s safe, the roof itself.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Have any paperwork from past roof work to hand
