How we price electronic leak detection
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Roof area
- If the survey needs thermal imaging or a drone
- The height of the building and how the roof can safely be seen
- Chimneys, valleys, parapets and other details
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
What we need to know
Getting the details right at the start saves time. It is useful to include:
- What’s prompted the survey
- Pictures from the garden or a window, if you have them
- Anything about access we should know
- Any marks or damp showing indoors
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
How electronic leak detection works in Stanstead Abbotts
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. Repair costs aren’t part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. You get a report with photographs. If you’re worried about stains far from any visible defect and failed seams and laps, we can find out what’s behind it, whatever the roof.
Some older homes in villages like Stanstead Abbotts are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Different roofs, different checks
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Bituminous membranes
Bituminous roofs frequently have laps and old repairs where breaches occur. Testing depends on the roof.
Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Clear flat roof outlets regularly
- Find the breach before more patching
- Limit access to the roof
- Get leaks traced quickly
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Don’t leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
Stanstead Abbotts questions
Is my home in Stanstead Abbotts listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you cover smaller places like Stanstead Abbotts?
Yes, Stanstead Abbotts is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Is my roof suitable for ELD?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof will not work, we will say so before testing.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put by urgency where it matters.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing typically needs a wet surface, while high-voltage testing needs a dry, exposed membrane.

What else we do in Stanstead Abbotts
Should I look at the roof myself first?
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
How the survey works
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. A typical visit takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Stanstead Abbotts, older homes can have small or awkward roof spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
How to prepare
- Move anything stored under the loft hatch
- Check pets are kept safely away
- Make sure we can get to the back of the property
Booking a survey

Electronic leak detection around Stanstead Abbotts
What can be done to an older roof may depend on listing or a conservation area. The council is the place to check, along with Historic England’s list. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For landlords with property near St Margarets (Herts) station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. The streets around a church such as Parish Church of St Andrew are frequently among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Take a building like The John Warner School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.
