Electronic Leak Detection in Little Almshoe
Electronic leak detection to pinpoint holes in flat roof membranes for Little Almshoe, from an experienced roof surveyor. You get a clear written report with photos.
- Damage from equipment installers
- Leaks through a flat roof with no obvious cause
- Leaks under green or ballasted roofs
What you can safely check yourself
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
About our electronic leak detection in Little Almshoe
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof cannot be tested. If you’ve noticed waterproofing to test before it’s covered and breaches hidden under paving or planting, we can find out what’s behind it.
In a small place like Little Almshoe, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Signs you need electronic leak detection in Little Almshoe
Seams are a common weak point in flat roof waterproofing. A gap that is hard to see can let water in long before anyone notices.
Problems we come across frequently include:
- Stains far from any visible defect
- Repairs that haven’t stopped the leak
- Gaps at membrane joints
- New membranes needing a check before handover
Landlords with a home close to Hitchin station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book any roof surveyor
- When you will get the report
- What they won’t be able to tell you
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
Tips from our surveys
These tips come from what we see on roofs every week, before and after a survey:
- Check new waterproofing before handover
- Share any drawings of the roof
- Note where leaks show inside and when
- Keep foot traffic on flat roofs to a minimum
File the report with your roof paperwork. It is a dated record of the membrane’s condition.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.

What we do, step by step
Once we’ve finished looking, we write up our findings as a written report with photos, emailed to you. On timing, most surveys take a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. For a village or hamlet like Little Almshoe, the journey is planned ahead of time: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Note where any stains or damp appear
- Leave side gates unlocked
- Move anything stored under the loft hatch

What affects the cost of electronic leak detection
To price your survey, we check:
- The type of building, from a house to a block or an office
- The number of roofs, including extensions and garages
- Whether thermal imaging or a drone is needed
- The size of the roof
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

- Where water is showing inside, if it is
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.
