Signs you need electronic leak detection in Lagness
When the membrane is buried, holes cannot be seen at all. Electronic methods can help on some of these roofs, depending on the build-up.
It is worth booking a survey if you’ve seen:
- Holes around roof penetrations
- Waterproofing to test before it is covered
- A flat roof leak that can’t be traced
- Damp inside with no sign on the roof
Take an older house close to Church of St Giles: the joins between later flat roofs and the old walls are where problems usually start.
Before booking any roof surveyor
- What insurance they carry
- When you’ll get the report
- Their track record with similar roofs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
Electronic leak detection for homes and businesses in Lagness
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Just ask about your roof. Typical surveys look at leaks that return after repairs and holes around roof penetrations, on roof terraces and balconies, liquid-applied waterproofing and commercial flat roofs.
Some older homes in villages like Lagness are listed or in a conservation area, which can shape what a new flat roof may look like. 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.
We write the report in plain English, so it makes sense without any roofing background. Photos show what each point refers to, with the urgent items made clear.

Your questions about electronic leak detection in Lagness
Do you cover smaller places like Lagness?
Yes, Lagness is covered. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Do roofs near the sea, like those around Lagness, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch.
What will the report tell me?
It works through the roof part by part, in writing and with photos. Points are put by urgency where it matters.
How experienced are you?
We’ve been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
How do I arrange electronic leak detection in Lagness?
Just ring 07833 053749 or email us. After a few questions, we confirm the price and fix a day.
Is the repair part of the test?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
What affects the price in Lagness
Not every roof costs the same to survey, for these reasons:
- The use of thermal imaging or a drone
- Building height and the viewpoints available
- The shape of the roof and its details
- Roof area
For a price for your roof in Lagness, call 07833 053749 or email us and let us know about the roof. The price is agreed before a date is set.

Photos help, if you have them. Pictures from the ground or a window are fine, and please don’t climb up for a closer look. To get started, ring 07833 053749 or drop us an email.
Flat roofs in Lagness
Lagness is within about 3 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Goodwood House, about 4.9 miles north, is one of the historic houses in the wider area around Lagness. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Bognor Regis station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building such as Rose Green Junior School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

What else we do in Lagness
The survey, step by step
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Lagness, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Check pets are kept safely away
- Check we can get to the back of the property
- Note where any stains or damp appear

Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Do not leave water getting in
- Clear flat roof outlets regularly
- Check new waterproofing before handover
- Keep a note of leaks after rain
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
