Electronic leak detection in Rowfant

Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof isn’t suitable, we’ll tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It saves a wasted visit. We are often asked to look into leaks at pipes, outlets or fixings and leaks that return after repairs, on commercial flat roofs, roof terraces and balconies and single-ply roofs.

Some older homes in villages like Rowfant are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.

If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

How the survey works

Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s 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. Rural addresses near Rowfant can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.

  1. We agree the area to be tested.
  2. We get the roof ready for testing.
  3. Testing runs across the agreed area.
  4. Each breach found is located and recorded.
  5. You receive the results to pass to your roofer.

Before we arrive

  • For a flat or shared roof, check access with the building owner or managing agent
  • Check we can get to the back of the property
  • Tell us where we can park nearby

Book a survey

Booking is simple: just phone 07833 053749 or email us and give us some details about the property and we will point you to the right survey. We confirm the price before anything is booked.

Your questions about electronic leak detection in Rowfant

Do you cover Rowfant?

We do. The survey and report are the same in Rowfant as anywhere else.

Does a conservation area affect roof work in Rowfant?

We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.

What’s the price of ELD?

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, call 07833 053749 or email us.

What happens after the survey?

We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.

Do you test for asbestos?

No. Asbestos surveys and sampling are not something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.

Does someone need to be in?

That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.

Does ELD work under paving or planting?

In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.

What we can’t see

It’s a careful look at the flat roof membrane, not the whole story. The main limits are:

  • Carrying out the repair work
  • Some conductive membranes
  • Sections we can’t safely access

If you’re not sure which survey you need, call 07833 053749 or use the contact form and we’ll give you a straight answer before you book. What our survey covers.

What this survey covers

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

Practical tips

From years of surveys, a few habits stand out as worth the effort:

  • Record dates and spots where water appears
  • Ask contractors to protect the membrane
  • Keep outlets clear of debris
  • Keep foot traffic on flat roofs to a minimum

Wet insulation may need attention after a leak. That is something to discuss with your roofer and other checks can help judge it.

Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.

Why it is worth a survey now in Rowfant

Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. For an older or listed building in a place like Rowfant, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.

The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

What we’re asked to look at in Rowfant

When the membrane is buried, holes can’t be seen at all. Electronic methods can help on some of these roofs though it depends on the layers.

Common reasons to book include:

  • Leaks through a flat roof with no obvious cause
  • Leaks showing away from the breach
  • Leaking laps in the waterproofing
  • Repairs that haven’t stopped the leak

If you own one of the older houses in the streets near All Saints Parish Church, flat-roofed rear additions and dormers added over the years are worth checking.

What to check before booking

  • Whether VAT is in the quoted price
  • Which viewpoints they use to see the roof
  • Their report turnaround times
  • What experience they bring

What’s in a roof survey

Flat and commercial roofs around Rowfant

About 2.7 miles south-east lies Gravetye Manor, a reminder of how long the area around Rowfant has been built on. If your home is one of the older ones, 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. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. A few old Sussex buildings still carry heavy Horsham stone slabs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.

Shop and office owners around County Mall may find that a flat roof over a business is out of sight and out of mind until it leaks. If you own a rental within reach of Three Bridges station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

DIY checks: what’s safe

A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.

What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
