Common roof problems in Warner Estate

Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.

We are often asked to look at:

  • Damp inside with no sign on the roof
  • New roofs to check before paving or planting
  • Leaks through a flat roof with no obvious cause
  • Failed seams and laps

Landlords with a home close to Walthamstow Central station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.

Before booking anyone

  • Will the report include photos?
  • Their report turnaround times
  • Whether you can ask questions once you have the report
  • Whether the roof space is looked at, where there is one

What a good roof survey covers

About our electronic leak detection in Warner Estate

You get a report showing the location of each breach with photos. Your roofer can then repair those points instead of hunting for the leak. 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, where the roof still suits the method. Results come in a written report with photos. If you’ve noticed holes around roof penetrations and gaps at membrane joints, a survey will tell you what’s going on, on commercial flat roofs, green roofs and flat roof membranes alike.

Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Warner Estate, the flat roof is often a shared part of the building.

After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

How the survey changes by roof type

Bituminous membranes

ELD is often possible on bituminous membranes, depending on what’s below.

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 in Warner Estate: local notes

Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Bruce Castle, about 2.2 miles west, show how far back building in the area around Warner Estate 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, and the council can say whether a home is in a conservation area.

Anyone responsible for a site like The Winns Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For a London address like Warner Estate, it helps to know about controlled parking before the day.

Warner Estate is about 1 mile north of Walthamstow, in Greater London.

Prices for electronic leak detection in Warner Estate

Prices vary from roof to roof, and it comes down to:

  • How tall the building is and how easy the roof is to see
  • How complicated the roof is, with its valleys, chimneys and parapets
  • How many separate roofs there are, such as extensions, dormers and garages
  • Whether it’s a home or a commercial building

All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.

Getting in touch

To price your survey accurately, we’ll ask about:

  • Why you want a survey: buying, a leak, a storm or new work
  • The type of building and roof, such as pitched or flat
  • Any stains, drips or damp patches you’ve seen indoors
  • Any deadline, such as an exchange date

To book a survey, phone 07833 053749 or use the contact form and let us know the address and what’s prompted the survey. You’ll know the price before anything is booked.

How it works

The visit has one job: to see as much of the flat roof membrane as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. The visit usually takes a length of time set by the membrane area and the build-up, which we set out in the quote. In Warner Estate, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.

  1. We start with what you know about the roof and the leak.
  2. We check whether the membrane and build-up suit ELD.
  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.

Getting ready for the survey

  • Jot down any questions you want answered
  • Leave side gates unlocked
  • If you are buying, check with the agent that we can get in

Advice

Why act early in Warner Estate

Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.

What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Why us?

  • An independent view of the roof
  • Over 5,000 surveys carried out
  • We hold a CAA Flyer ID and Operator ID
  • Professional indemnity and public liability insurance

Useful tips for Warner Estate property owners

Over many surveys, some simple habits stand out as worth the effort:

  • Share any drawings of the roof
  • Stay off the flat roof unless needed
  • Don’t let outlets block
  • Record dates and spots where water appears

If anything in the report isn’t clear, ask us. We can talk you through the findings.

Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
