Meriden Electronic Leak Detection
An experienced roof surveyor for electronic leak detection in Meriden. Over 5,000 surveys and 20+ years behind us.
- Water coming in under a flat roof
- New membranes needing a check before handover
- Breaches hidden under paving or planting
How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. With a bit of garden around a house, as there often is around Meriden, the roof can be viewed from several angles. Mention any side of the property we can’t get to. Inside, the loft is looked at where it can be reached safely.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Agree roof access with the managing agent if it’s shared
- If you are buying, let the agent know when we are coming
Arrange a survey
Most bookings start with a short call: call 07833 053749 or use the contact form and we will ask a few questions about the roof. You’ll have a price before anything is arranged.

Electronic leak detection for homes and businesses in Meriden
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. If testing isn’t possible, we’ll say so. If you’ve noticed leaks showing away from the breach and punctures from foot traffic or tools, a survey will tell you what’s going on, whatever the roof.
Outbuildings, garden rooms and garages in places like Meriden often have flat roofs of their own. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when you book, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, like when you want to compare after future work.

Common roof problems in Meriden
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
These are some of the problems a survey can pick up:
- Leaks showing away from the breach
- Breaches around outlets and penetrations
- Failed seams and laps
- Damage from equipment installers
Hotels and guest houses near Meriden cannot easily close rooms for a leak, so it pays to find faults before guests do.
Questions to ask before booking
- Their track record with similar roofs
- Whether the price includes VAT
- Their drone registration, if they fly one
- What follow-up you get after the report
Meriden questions
Do you cover smaller places like Meriden?
Yes, Meriden is covered. We work right across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Do you look at commercial flat roofs near Meriden, such as hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building.
What happens next?
We email you the written report with photos and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you need to get into the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.
Does the report include photos?
Yes. Photographs are taken throughout the survey, and they go into the written report alongside our recommendations.
What will the report tell me?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put in order of urgency where relevant.
Checking the roof from ground level
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where applicable.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Flat and commercial roofs around Meriden
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With High Elms Manor about 1.6 miles north, Meriden sits in an area with a long building history. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For businesses in and around places such as Charter Place, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building like The Grove Academy, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
