Electronic leak detection near St Ippolyts

Why act early in St Ippolyts

Opening up a roof to hunt for a leak is disruptive. ELD aims to locate the breach first so your roofer knows where to work. In a place like St Ippolyts, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.

To find out what your survey will cost, call 07833 053749 or email us and let us know about the roof. The price is agreed before a date is set.

Electronic leak detection in St Ippolyts

Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. Typical surveys look at leaks at pipes, outlets or fixings and damp inside with no sign on the roof, on liquid-applied waterproofing, green roofs and flat roof membranes.

Older buildings in small places like St Ippolyts may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re 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.

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.

Before and after the survey

Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:

  • Avoid repeated repairs without finding the cause
  • Have roof specifications to hand
  • Test new membranes before covering them
  • Get leaks traced quickly

Keep the report with the roof’s records. It shows the condition of the membrane on that date.

Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.

Electronic leak detection around St Ippolyts

In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. There are several hotels within about a mile and a half of St Ippolyts, and hotels, like offices and blocks of flats, often have flat roofs. If you look after one, a leak through a flat roof can put a room out of use.

Take a building like St Ippolyts Church of England Aided Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Knebworth House, about 4.4 miles south-east, is one of the historic houses in the wider area around St Ippolyts. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.

The survey, step by step

You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. In a small place like St Ippolyts, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.

  1. You tell us about the roof and where water is showing.
  2. The roof is assessed for suitability first.
  3. We choose a low-voltage or high-voltage method to match the roof.
  4. The membrane is tested and breaches are found.
  5. You get a report with photos of each breach.

  • Any need for thermal images or a drone flight
  • Height and safe access
  • Roof area
  • Extensions, dormers and garages with roofs of their own

What we are asked to look at in St Ippolyts

Holes in a membrane frequently come from feet, tools or debris. Some are too small to see but water still finds them.

Here are some of the things we see often:

  • Damp inside with no sign on the roof
  • Leaking laps in the waterproofing
  • New membranes needing a check before handover
  • Breaches around outlets and penetrations

If you let a flat or house near Hitchin station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

  • What’s outside the scope of the survey
  • How they plan to inspect the roof safely
  • Whether you can ask questions once you have the report

Your questions about electronic leak detection in St Ippolyts

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

Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.

Can you look at the flat roof of a hotel or office near St Ippolyts?

Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.

Can you survey in bad weather?

It depends on the weather and the survey. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.

How long will testing take?

It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.

Do you need to get into the loft?

Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.

How do you choose the testing method?

We choose the method that suits the roof. We will explain why when we quote.

What do I do with the report?

The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
