Smallford Electronic Leak Detection
Electronic leak detection in Smallford and the rest of Hertfordshire. We survey seven days a week.
- New roofs to check before paving or planting
- Failed seams and laps
- Leaks through a covered membrane
What we do, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. In a small place like Smallford, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Getting ready for the survey
- Let us know about parking before the day
- Check the loft hatch can be reached
- Keep pets inside or away from the areas we are looking at
Arrange a survey
Getting a price is simple: just call 07833 053749 or send us an email, let us know about the property and we’ll explain which survey suits. We confirm the price before anything is booked.

Electronic leak detection in Smallford
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We don’t estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. Results come in a written report with photos. We survey green roofs, flat roof membranes and liquid-applied waterproofing, and people most frequently book us about breaches hidden under paving or planting and leaks that return after repairs.
In a village or hamlet like Smallford, flat roofs are typically on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
After the visit, you get a written report with photos, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. We survey on any day of the week, which can make access easier.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Leave it or get it looked at?
Not every leak is in the membrane. Testing shows whether the membrane is breached, so other causes can be checked. Older cottages and farmhouses around Smallford can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

What to let us know when you get in touch
There’s no need for technical words. It is enough to let us know:

- The reason for the survey, such as buying, a leak or storm damage
- What kind of property and roof it is

Common questions in Smallford
Are flat-roofed garages and porches in Smallford worth including?
Often, yes, so mention it as you book. Flat-roofed garages and porches are common in new towns like Hatfield, and older felt coverings may be near the end of their life.
Is Smallford within the area you cover?
Yes, we do. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How much time does ELD need?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
Can you tell me if my roof has asbestos?
No. We don’t carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
Do you survey on Saturdays and Sundays?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or drop us an email.
When does the report arrive?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.
Signs you need electronic leak detection in Smallford
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in for months before it shows.
A survey makes sense if you’ve noticed:
- Leaks under green or ballasted roofs
- New roofs to check before paving or planting
- Leaks that return after repairs
- Stains far from any visible defect
Anyone responsible for a site like Nicholas Breakspear Catholic School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether they hold professional indemnity and public liability insurance
- How long the report takes to arrive
- How they plan to inspect the roof safely
Flat and commercial roofs around Smallford
About 2.7 miles east lies Hatfield House, a reminder of how long the area around Smallford has been built on. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Hatfield, which Smallford is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed.
For businesses in and around places such as The Maltings, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you live in an older home near Church of St Mark, the flat roofs on later extensions tend to wear out long before the main roof.
