Roof by roof
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Electronic leak detection in Lexden: what you get
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. We survey commercial flat roofs, roof terraces and balconies and liquid-applied waterproofing, and people most often book us about failed seams and laps and damage from equipment installers.
Around a smaller place like Lexden, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What electronic leak detection looks like in Lexden
Before planning roof work on an older home, find out whether it is listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you live in an older home near Church of St Leonard, the flat roofs on later extensions tend to wear out long before the main roof. Shop and office owners around Lion Walk may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.

- Stains far from any visible defect

- Is VAT included in the price?

- How long the report takes to arrive
What affects the cost of electronic leak detection
Not every roof costs the same to survey, and it comes down to:
- Whether thermal imaging or a drone is needed
- The number of roofs, including extensions and garages
- How complicated the roof is, with its valleys, chimneys and parapets
- The height of the building and how the roof can safely be seen
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What we need to know
You don’t need to know any roofing terms. It is enough to let us know:
- Any stains, drips or damp patches you’ve seen indoors
- How the loft is reached, if there is one
- Where the property is, with the postcode
- Pictures of the roof from a safe spot, if you have them
Getting a price is simple: just ring 07833 053749 or use the contact form and give us some details about the property and we will recommend the right survey. We confirm the price before anything is booked.
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.

Do you look at commercial flat roofs near Lexden, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.

How the survey works
Safety comes first on every visit. We inspect everything that’s safely in view, and if part of the roof cannot be seen, the report says so. The survey normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Parking around Lexden is typically easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can frequently be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before the survey
- Find any records of previous roof work
- If the roof is shared, arrange access with whoever manages the building
- Leave a clear route to the loft
Getting a price
Photos help, if you have them. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To get started, call 07833 053749 or email us.
