Electronic Leak Detection in West Mersea

Electronic leak detection for homes and businesses in West Mersea
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it is covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. Common reasons to book are gaps at membrane joints and leaks that return after repairs, on flat roof membranes, liquid-applied waterproofing and green roofs.
Around West Mersea, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It is worth mentioning them when you book, so the visit can include them, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
After the visit, you get a photo-illustrated written report, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

When to book a survey in West Mersea
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Common reasons to book include:
- Damp inside with no sign on the roof
- Leaking laps in the waterproofing
- New roofs to check before paving or planting
- Leaks under green or ballasted roofs
The streets around a church like Church of St Peter and St Paul are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
Choosing a roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How long the report takes to arrive
- What experience they bring
- Whether they hold professional indemnity and public liability insurance
DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: 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.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.
Different roofs, different checks
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Some methods can work through these layers but it depends on the layers.
Single-ply membranes
Punctures from foot traffic and equipment are common on single-ply roofs. Testing helps find them.
The survey, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. A visit to a smaller place like West Mersea is no different on the day: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- First, you tell us about the roof build-up and where water is showing.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Tell us about any leaks, stains or damp patches you know of
- Check we can get to the back of the property
- Keep pets in another room
Booking a survey
Photos help, if you have them. Pictures from the ground or a window are fine. To get started, phone 07833 053749 or email us.

Local flat roofs in West Mersea
West Mersea is within about 2 miles of the coast, and being near the sea means more wind and salt than a roof inland would face. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
Anyone responsible for a site like Mersea Island School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Why get it checked now?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. In a smaller place like West Mersea, wherever a roof is exposed, a loose ridge or flashing doesn’t stay loose for long. Wind gets under it and lifts more.

FAQs for West Mersea
Is my home in West Mersea listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Does being near the coast affect roofs in West Mersea?
Often, yes. West Mersea is within about 2 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put in order of urgency where relevant.
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first, with whoever owns or manages the building. Let us know about it when you book and we’ll explain what’s needed.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
How long will testing take?
Testing usually takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote.
