Electronic leak detection in Pin Green
Some flat roofs can’t be tested electronically. Some membranes conduct electricity themselves and some roofs don’t have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof at the start. Any details you have about the membrane and build-up help us decide, like drawings or specifications. It avoids arranging a test that cannot give results. If you’re worried about damage from equipment installers and gaps at membrane joints, a survey will tell you what’s going on, on liquid-applied waterproofing, commercial flat roofs and green roofs alike.
Around Pin Green, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. If you want them looked at too, mention them when you book. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Your questions about electronic leak detection in Pin Green
Should a flat-roofed garage or porch in Pin Green be checked too?
It is often worth it, as these roofs are easy to forget. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Do you cover smaller places like Pin Green?
Yes, Pin Green is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email.
How do I arrange electronic leak detection in Pin Green?
Simply ring 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, so you can see what we mean.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof and high-voltage methods need the membrane dry and exposed.

What else we do in Pin Green
Flat roofs in Pin Green
The wider area around Pin Green has a long history of building, with Aston Bury about 3 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If your home is one of the older ones in the streets near Church of Saint Nicholas, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a building such as Trotts Hill Primary and Nursery School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Before and after the survey
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Stay off the flat roof unless needed
- Record dates and spots where water appears
- Get leaks traced quickly
- Find the breach before more patching
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
Act on leaks quickly. Water under a membrane can spread.
Rented homes, blocks and businesses
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant.
How the survey works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photographs as we go and make notes for the report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. For a survey in Pin Green, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. Tell us about any garages, outbuildings or extensions you want included.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Preparing for the visit
- Make a note of anything you’d like us to look at
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches
Getting a price

Advice
DIY checks: what’s safe
You can learn a lot from ground level. 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.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
What affects the cost of electronic leak detection
A few things affect what a survey costs:
- House, block, shop or office
- Height and safe access
- Extensions, dormers and garages with roofs of their own
- Features like valleys, chimneys, dormers and parapets
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
What we need to know
There’s no need for technical words. It’s enough to let us know:
- Dates you’re working to, like exchange
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
- The style of property, from a terrace to a block
If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or email us when you are ready.
Signs you need electronic leak detection in Pin Green
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
It is worth booking a survey if you’ve seen:
- Damage from equipment installers
- Leaks that return after repairs
- Leaks through a flat roof with no obvious cause
- Holes around roof penetrations
If you let a flat or house near Stevenage station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the price includes VAT
- Which limits apply to the survey
- How they plan to inspect the roof safely
