Electronic leak detection for Islip homes and businesses

Electronic leak detection for homes and businesses in Islip

Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. Typical surveys look at leaks under green or ballasted roofs and leaks that return after repairs, on single-ply roofs, commercial flat roofs and liquid-applied waterproofing.

Somewhere as small as Islip, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.

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.

Landlord and commercial surveys in Islip

Businesses and commercial landlords can book us too, including offices, shops and units. Larger roofs take longer, and they’re priced for the size.

We survey roofs for letting agents and landlords as well as homeowners. A written report with photos gives you a clear record of the flat roof membrane.

Flat and commercial roofs around Islip

Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. With Holywell Manor about 4.6 miles south, Islip sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.

For an older house near a landmark such as St Nicholas' Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Landlords with a home close to Islip station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Islip is about 5 miles north of Oxford, in Oxfordshire. Roofs in Islip get the same thorough look as anywhere else in Oxfordshire. Islip is one of the places in Oxfordshire where we work for electronic leak detection.

What you can safely check yourself

A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.

After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.

How it works

The visit has one job: to see as much of the flat roof membrane as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. The visit typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Rural addresses near Islip 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. After that, the survey runs as it would anywhere.

  1. We ask about the roof, its age, its membrane and where leaks appear inside.
  2. We confirm whether the roof is suitable for electronic testing.
  3. We pick the low-voltage or high-voltage method that suits the roof.
  4. The roof is tested and any breaches are located.
  5. We send a report with photos of each breach so your roofer can repair it.

How to prepare

  • If it isn’t your property yet, arrange access through the agent
  • Unlock side gates and any roof access doors
  • Let us know about parking near the property

Related advice

Roof by roof

Green and ballasted roofs

ELD is easier on a new roof before it is covered.

Inverted and paved roofs

If the build-up rules out ELD, we will say so.

Do you need electronic leak detection in Islip?

Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.

A survey makes sense if you’ve noticed:

  • Breaches around outlets and penetrations
  • Leaking laps in the waterproofing
  • New roofs to check before paving or planting
  • Leaks through a flat roof with no obvious cause

Take a building like Dr South's Church of England Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Questions to ask before booking

  • Whether the inside of the roof is included
  • What follow-up you get after the report
  • When you’ll get the report
  • Whether any drone flown is registered with the CAA

What to expect from a roof survey

Islip questions

Do you carry out roof surveys in Islip?

Yes, Islip is one of the places we work. Every survey there gets the same written report with photos.

Do you cover smaller places like Islip?

Yes. Islip is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there as you book.

What do I do with the report?

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 survey roofs on blocks of flats?

Yes, if the building owner or managing agent agrees access. We look at the parts we are given access to, and the report makes that clear.

Does electronic leak detection work on all membranes?

ELD doesn’t suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours isn’t suitable before testing.

Which days do you carry out surveys?

Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days when you book.

Will I get photos?

Yes. Photographs are taken throughout the survey, and they go into the written report.

When you need someone else

It’s useful to know what a survey will not do before booking:

  • Some conductive membranes
  • Leaks from walls, copings or rooflights
  • How wet the insulation is

If in doubt, phone 07833 053749 or email us and we will recommend the right survey before booking. What a survey covers and doesn’t.
