Electronic leak detection in Sudbury

About our electronic leak detection in Sudbury

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 because they show what’s under the surface. If testing isn’t possible, we’ll say so. We survey roof terraces and balconies, liquid-applied waterproofing and green roofs, and people most often book us about a flat roof leak that can’t be traced and leaks showing away from the breach.

London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in Sudbury shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.

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.

What electronic leak detection does not cover

This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:

  • Leaks from walls, copings or rooflights
  • Parts of the roof covered by fixed equipment
  • Fixing the holes we find

If in doubt, call 07833 053749 or drop us an email and we will suggest the right survey. What a survey covers and does not.

Roofs we survey in Sudbury

  • Liquid-applied waterproofing
  • Green roofs
  • Commercial flat roofs
  • Roof terraces and balconies
  • Flat roof membranes
  • Single-ply roofs

What happens if roof problems are left?

Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.

Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for your roof before you book.

Local flat roofs in Sudbury

There are several hotels within about a mile and a half of Sudbury, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Historic houses like Northolt Manor, about 2.2 miles west, show how far back building in the area around Sudbury goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.

If you look after a shop, office or commercial unit, for example near London Designer Outlet, outlets and upstands on commercial flat roofs are the places to check before trouble starts. For an older house near a landmark like Church of St Andrew, the joins between later flat roofs and the old walls are where problems typically start. If you run a hotel or guest house in or near Sudbury, a roof problem can mean rooms out of use, so it is worth knowing the roof’s condition.

Sudbury is about 1 mile south-west of Wembley, in Greater London. Bookings from Sudbury are handled just like any other: a call or an email, a price, then a date. Our Greater London coverage includes Sudbury and the places around it. Our London page covers surveys nearby.

The survey, step by step

There is not much for you to do on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes a time that depends on the membrane area and the build-up, and we’ll give you a guide when quoting. From the street, a London terrace usually shows only its front slope or parapet, so in Sudbury we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Tell us 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. We choose a low-voltage or high-voltage method to match the roof.
  4. We test the roof and locate any breaches.
  5. A report with photos shows where each breach is.

How to prepare

  • Keep pets inside or away from the areas we are looking at
  • Move anything stored under the loft hatch
  • Have keys ready for side gates, garages or roof access doors

How to book

If you have photos of the roof, send them over. Pictures from ground level or a window are fine. To get started, ring 07833 053749 or send us an email.

Advice

What we look for on each type of roof

Inverted and paved roofs

We’ll tell you if your inverted or paved roof is not suitable.

Bituminous membranes

Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.

Surveys for landlords and agents in Sudbury

If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or send us an email with the addresses.

For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.

What affects the cost of electronic leak detection

Not every roof costs the same to survey, and it comes down to:

  • House, block, shop or office
  • Chimneys, valleys, parapets and other details
  • If the survey needs thermal imaging or a drone
  • How tall the building is and how easy the roof is to see

Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

Booking your survey

When you call or email, these details help:

  • Any photos you have, taken from the ground or a window
  • Where the property is, with the postcode
  • How the loft is reached, if there is one
  • Any stains, drips or damp patches you’ve seen indoors

To get a price for electronic leak detection in Sudbury, phone 07833 053749 or send us an email. The address, the type of property and what you want to find out help us give you an accurate price.

Sudbury: your questions answered

Do you look at commercial flat roofs near Sudbury, like hotels?

Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building, and roof access is agreed with you ahead of the visit.

How do I find out if my home in Sudbury is listed?

The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.

What’s the best way to book?

The quickest way is to phone 07833 053749 or send us an email. Give us the address and some details about the roof, and we will point you to the right survey. Surveys run seven days a week.

Is it a structural engineer’s report?

No. We note visible signs like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.

How is ELD priced?

Each roof is quoted on its size and build-up. Tell us about the roof and where it leaks. Just call 07833 053749 or drop us an email for a quote.

Can you tell me if my roof has asbestos?

No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.

What does the report include?

It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
