Electronic leak detection in Kew

What we look for on each type of roof

Bituminous membranes

Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.

EPDM rubber roofs

Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.

Electronic leak detection for homes and businesses in Kew

We carry out electronic leak detection on flat roofs in Kew and across London and South East England. Testing normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a written report with photos. If you are worried about gaps at membrane joints and water coming in under a flat roof, a survey will tell you what’s going on, whatever the roof.

Offices, shops and blocks of flats across London frequently have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. In Kew, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.

We keep jargon out of it: if work is needed, the report says so clearly.

Electronic leak detection in Kew: local notes

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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. There are several hotels within about a mile and a half of Kew. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.

Anyone responsible for a site like Grove Park Primary School will know that a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. If you live in an older home near St Paul's Church, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Shop and office owners around Livat Hammersmith may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.

Kew is about 2 miles south of Acton, in Greater London. We carry out electronic leak detection in Kew for houses, flats, blocks and commercial buildings, with a written report and photographs every time. Our Greater London coverage includes Kew. For surveys nearby, see our London page.

What affects the cost of electronic leak detection

We confirm the price for your roof before booking. These are the things that affect it:

  • The size of the roof
  • The shape of the roof and its details
  • The type of building, from a house to a block or an office
  • How many separate roofs there are, such as extensions, dormers and garages

Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.

Helping us price your survey

These details help when you contact us:

  • Any photos you have, taken from ground level or a window
  • Anything about access we should know
  • Where any leaks, stains or damp patches show inside
  • Any deadline, such as an exchange date

You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, phone 07833 053749 or email us.

Before and after the survey

Nothing here needs a ladder. Our suggestions:

  • Ask contractors to protect the membrane
  • Clear flat roof outlets regularly
  • Keep foot traffic on flat roofs to a minimum
  • Keep a note of leaks after rain

Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.

Act on leaks quickly. Water under a membrane can spread.

How it works

We’ll ask a few questions first, like when any problem began and what work has been done before. The inspection then takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. From the street, a London terrace usually shows only its front slope or parapet, so a visit in Kew moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.

  1. We start with what you know about the roof and the leak.
  2. The roof is assessed for suitability first.
  3. The test method is chosen to suit the roof.
  4. We test the roof and locate any breaches.
  5. You get a report with photos of each breach.

Preparing for the visit

  • Check we can get to the back of the property
  • Clear the way to the loft hatch
  • Find any records of previous roof work

Arrange a survey

If you’re buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.

Related advice

Can I check my roof myself?

You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.

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.

Kew: your questions answered

Do you look at commercial flat roofs near Kew, such as hotels?

Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.

Will parking be an issue for a roof survey in Kew?

It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.

How soon will I get the report?

Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when booking.

How do I arrange electronic leak detection in Kew?

It is easiest to call 07833 053749 or email us. Let us know the address and a little about the roof, and we’ll suggest the right survey. We survey on weekdays, Saturdays and Sundays.

What do I do with the report?

You’ll receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.

How experienced are you?

We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.

How much does electronic leak detection cost?

Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or send us an email.

Why get it checked now?

Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.

For a price for your roof in Kew, ring 07833 053749 or email us and tell us about the roof. The price is agreed before a date is set.
