How electronic leak detection works in Gadebridge
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It can be used to trace an existing leak or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Let us know about your roof to find out more. Typical surveys look at repairs that haven’t stopped the leak and leaks through a flat roof with no obvious cause, across liquid-applied waterproofing, single-ply roofs and commercial flat roofs.
In smaller places like Gadebridge, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let lots of water into the room below. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Local flat roofs in Gadebridge
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you let a flat or house near Hemel Hempstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Galley Hill Primary School and Nursery: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

What we look for on each type of roof
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Seams and penetrations are typical breach points.
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. We test where the roof suits it.
Do you need electronic leak detection in Gadebridge?
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
We are frequently asked to look at:
- Leaks through a flat roof with no obvious cause
- Leaks under green or ballasted roofs
- Repairs that haven’t stopped the leak
- Damp inside with no sign on the roof
For an older house near a landmark such as St Alban's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What we do, step by step
Every roof is different; as a rough guide, the survey takes more time on a big roof than a small one, with the construction of the roof playing a part too. If you have questions on the day, just ask. For a survey in Gadebridge, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. Let us know about any garages, outbuildings or extensions you want included.
- 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.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Make sure we can get to the back of the property
- Let us know about parking before the day
- Gather any invoices or paperwork from past roof work
Book a survey
A quick phone call is normally the easiest start: ring 07833 053749 or drop us an email, and we’ll ask about the building and what you need. You’ll have a price before anything is arranged.

Prices for electronic leak detection in Gadebridge
Prices vary from roof to roof, for these reasons:
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether it is a home or a commercial building
- The size of the roof
- Whether thermal imaging or a drone is needed
What a survey costs comes down to the roof itself: 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.

Questions from Gadebridge
How do I find out if my home in Gadebridge is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Are flat-roofed garages and porches in Gadebridge worth including?
Frequently, yes, so mention it as you book. Many homes in new towns like Hemel Hempstead have flat-roofed garages and porches, and felt roofs frequently last around 15–20 years.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us as you book.
Does the report include photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Is it a structural engineer’s report?
No. Visible signs like deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
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.
Rented homes, blocks and businesses
We survey roofs for landlords and agents as well as householders. The report gives you a dated record of the flat roof membrane, with photos, which helps you plan work between tenancies.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
