FAQs for Orpington

Do you carry out roof surveys in Orpington?

Yes, Orpington is within the area we cover. Our area covers London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property.

Does a conservation area affect roof work in Orpington?

For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.

How much time does ELD need?

Testing normally takes a time that depends on the membrane area and the build-up, which we set out in the quote.

Can you survey a shared roof?

Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.

What if it rains on the day?

It can, depending on the survey. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We’ll rearrange with you if the weather is not right.

What’s the best way to book?

To book, phone 07833 053749 or use the contact form and let us know the address and what you’d like to know. We’ll confirm the price and find a day that suits.

Does the report include photographs?

Yes, plenty. Pictures sit next to the findings they show, so you can see what we mean.

Electronic leak detection for homes and businesses in Orpington

You get a report showing the location of each breach, with photos. Your roofer can then repair those points 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. You get a written report with photos. We survey commercial flat roofs, flat roof membranes and green roofs, and people most often book us about repairs that haven’t stopped the leak and leaks at pipes, outlets or fixings.

Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats 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 Orpington shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.

After the visit, you get a written report with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Why get it checked now?

Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out so attention can go to the right place. 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, rather than in a rush after a leak.

Every price we give includes 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.

Why book us in Orpington

  • An independent look at the roof
  • Satisfaction rate of 98%
  • Professional indemnity and public liability insurance
  • A photo-illustrated written report

What we cannot see

Some things can’t be seen without opening up the roof, and that sets some limits:

  • Build-ups without a suitable layer below
  • Water entering through details rather than the membrane
  • Parts of the roof covered by fixed equipment

If in doubt, phone 07833 053749 or email us and we’ll suggest the right survey before you book. The full list of what we check.

What this survey covers

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

What affects the price in Orpington

The price reflects the time and kit the roof needs. The main factors are:

  • Chimneys, valleys, parapets and other details
  • How many separate roofs there are, like extensions, dormers and garages
  • Roof area
  • Commercial roofs and larger buildings

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

Booking your survey

A few details help us point you to the right survey and price. When you contact us, it helps to mention:

  • Your timetable, like an exchange date
  • The type of building and roof, such as pitched or flat
  • Pictures of the roof from a safe spot, if you have them
  • The address and postcode of the property

We confirm the price for your survey before you book, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or drop us an email.

How the survey works

A survey visit follows a simple order: we hear what you’ve seen, inspect the roof from every safe vantage point, photograph what we find and make notes for the report. It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In Orpington, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when booking.

  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. A report with photographs shows where each breach is.

Preparing for the visit

  • Point out any leaks or damp patches
  • If you’re buying, check with the agent that we can get in
  • Move anything stored under the loft hatch

Arrange a survey

A quick phone call is normally the easiest start: ring 07833 053749 or use the contact form, and we’ll ask about the building and what you need. You will have a price before anything is arranged.

Advice

Do you need electronic leak detection in Orpington?

A breach can be left during installation. Testing before the roof is covered or handed over helps find them.

Typical things we are asked to look at include:

  • Waterproofing to test before it is covered
  • Leaks through a flat roof with no obvious cause
  • Breaches hidden under paving or planting
  • Leaks at pipes, outlets or fixings

Anyone responsible for a site like Perry Hall Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What to check before booking

  • What experience they bring
  • When you will get the report
  • What they won’t be able to tell you
  • What the report includes, and whether it has photographs

Practical tips

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

  • Don’t keep patching the same spot
  • Test new membranes before covering them
  • Make sure trades protect the waterproofing
  • Record dates and spots where water appears

File the report with your roof paperwork. It’s a dated record of the membrane’s condition.

Make sure contractors protect the waterproofing when fitting equipment. Check the roof after they’ve finished.

Electronic leak detection around Orpington

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. If your home in Orpington is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 3.8 miles west lies Bromley Palace, a reminder of how long the area around Orpington has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.

If you run a business near The Mall, the flat roofs over shops and commercial units are worth checking before a leak, not after. For an older house near a landmark such as St Andrew's, the joins between later flat roofs and the old walls are where problems normally start.
