Electronic leak detection in Bexley

About our electronic leak detection in Bexley

Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use and parts may need to be lifted. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof can’t be tested. We survey flat roof membranes, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are a flat roof leak that can’t be traced and holes around roof penetrations.

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, and each fails in its own way. Which one is on a roof in Bexley shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.

The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Checking the roof from ground level

A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.

Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.

What we’re asked to look at in Bexley

New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.

Common reasons to book include:

  • Damp inside with no sign on the roof
  • Leaks through a covered membrane
  • Water coming in under a flat roof
  • Leaks that return after repairs

As a London address, Bexley can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.

What to expect from a roof survey

How it works

We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes longer on a large 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 in Bexley 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? Let us know who holds the keys.

  1. We ask about the roof, its age, its membrane and where leaks appear inside.
  2. We check that the membrane and build-up suit electronic leak detection.
  3. The testing method is chosen to suit the membrane and build-up.
  4. We test the membrane and find where current is passing through it.
  5. We send a report with photos of each breach so your roofer can repair it.

Before the survey

  • Point out any leaks or damp patches
  • Dig out any old roof reports or invoices
  • Mention any parking restrictions on your street

Booking a survey

FAQs for Bexley

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

You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.

Is Bexley in the area you cover?

Yes, Bexley is within the area we cover. We survey roofs across London and South East England. Just ring 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.

How long will testing take?

The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.

What will the report tell me?

It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.

Will you check the loft?

Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.

Will you walk on the roof?

Only if it is safe. We check everything that can be seen safely: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where applicable. Anything we cannot see is noted in the report.

Does someone need to be in?

Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.

Electronic leak detection in Bexley: 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. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Red House, about 0.9 miles north, show how far back building in the area around Bexley goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.

If you let a flat or house near Bexley station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For businesses in and around places such as Broadway Shopping Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

Before and after the survey

Over many surveys, some simple habits stand out:

  • Limit access to the roof
  • Clear flat roof outlets regularly
  • Keep a note of leaks after rain
  • Check new waterproofing before handover

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

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

Rented homes, blocks and businesses

Letting agents can arrange access with tenants. We survey on any day of the week, which helps when tenants work during the week.

Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it as you book and we’ll plan the survey around it.
