Electronic leak detection in Weston, Hertfordshire
An experienced roof surveyor for electronic leak detection in Weston. More than 20 years and over 5,000 surveys across London and South East England.

Electronic leak detection in Weston: what you get
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 and locates the breach. We test and report and leave the repair to 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. If you are worried about damage from equipment installers and a flat roof leak that can’t be traced, a survey will tell you what’s going on.
Some older homes in villages like Weston are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, with the urgent items made clear.

Weston: your questions answered
Do you cover Weston?
Yes, Weston is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Do you cover smaller places like Weston?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. We will talk about access as you book.
How do I arrange electronic leak detection in Weston?
The quickest way is to ring 07833 053749 or send us an email. Tell us the address and a little about the roof, and we’ll take it from there. We survey on weekdays and at weekends.
How does ELD work?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, phone 07833 053749 or email us.

What electronic leak detection doesn’t cover
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- The extent of water in the insulation
- Repairing the breaches (that’s for your roofer)
- Some conductive membranes
If you are not sure which survey you need, ring 07833 053749 or drop us an email and we’ll give you a straight answer before booking. What our survey covers.
What we check
- Flat roof membranes
- Commercial flat roofs
- Roof terraces and balconies
- Green roofs
- Single-ply roofs
- Liquid-applied waterproofing
What affects the cost of electronic leak detection
What a survey costs depends on the time and equipment it needs. That comes down to:
- The size of the roof
- Features like valleys, chimneys, dormers and parapets
- The use of thermal imaging or a drone
- How many separate roofs there are, such as extensions, dormers and garages
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You will know the figure before booking.
What to tell us when you contact us
The more you tell us, the easier it is to price the survey. When you contact us, tell us:
- Any marks or damp showing indoors
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- When you need the report by
We confirm the price for your roof before booking, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, call 07833 053749 or email us.
The survey, step by step
Safety comes first on every visit. We inspect what can be seen safely, and anything we cannot see is noted in the report. 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. Older rural homes like those around Weston can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
How to prepare
- Move anything stored under the loft hatch
- Keep pets out of the way during the survey
- Have any paperwork from past roof work to hand
How to book
If you have photos of the roof, send them over. Pictures from ground level or a window are fine. To get started, phone 07833 053749 or send us an email.

Flat roofs in Weston
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 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, so the council is the place to ask. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you own a rental within reach of Baldock station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Weston Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Common roof problems in Weston
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Typical things we’re asked to look at include:
- Leaks through a flat roof with no obvious cause
- Gaps at membrane joints
- Breaches hidden under paving or planting
- Damage from equipment installers
If yours is one of the older homes in the streets near Church of the Holy Trinity, the flat roofs on later extensions tend to wear out long before the main roof.

Roof by roof
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing, which affects testing.
Single-ply membranes
ELD frequently works on single-ply membranes, depending on the type and build-up.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
