How electronic leak detection works in Kingston upon Thames
You get a report showing the location of each breach, with photos. It tells your roofer exactly where to repair rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. If you’ve noticed new membranes needing a check before handover and leaks that return after repairs, we can find out what’s behind it.
Commercial and residential blocks across London frequently have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. In Kingston upon Thames, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Note where leaks show inside and when
- Have roof specifications to hand
- Keep foot traffic on flat roofs to a minimum
- Keep outlets clear of debris
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
Common questions in Kingston upon Thames
Does a conservation area affect roof work in Kingston upon Thames?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Can you look at the flat roof of a hotel or office near Kingston upon Thames?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Which days do you carry out surveys?
Visits run seven days a week in the daytime. Just say which days work for you.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather is not right.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Landlord and commercial surveys in Kingston upon Thames
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.
Checking the roof from the ground
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. London terraces rarely offer a view of the whole roof from one spot, so a visit in Kingston upon Thames moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Tell us who holds the keys.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or drop us an email.

Other services in Kingston upon Thames
Do you need electronic leak detection in Kingston upon Thames?
Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.
A survey can pick up problems like:
- Holes around roof penetrations
- Damage from equipment installers
- Gaps at membrane joints
- A flat roof leak that can’t be traced
If yours is one of the older homes in the streets near Church of St Luke, the joins between later flat roofs and the old walls are where problems normally start.
Choosing a roof surveyor
- Are they insured for the work?
- What’s outside the scope of the survey
- How long they’ve been surveying roofs
- Whether VAT is added on top
Flat and commercial roofs around Kingston upon Thames
Hampton Court Palace, about 1.8 miles south-west, is one of the historic houses in the wider area around Kingston upon Thames. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you look after a shop, office or commercial unit, for example near Bentall Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. For landlords with property near Kingston station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
