Electronic leak detection in Highfield: what you get
ELD finds breaches in the membrane, not every cause of water getting in. Leaks from walls, copings, rooflights or pipes need other checks. If the evidence points elsewhere, we’ll say so. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. Typical surveys look at holes left by work on the roof and leaks through a flat roof with no obvious cause, across green roofs, single-ply roofs and commercial flat roofs.
Outbuildings, garden rooms and garages in places like Highfield frequently have flat roofs of their own. 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.
Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

How the survey works
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where it applies. The survey usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Some parts of a survey depend on the weather, so a visit to Highfield is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before the survey
- Gather any invoices or paperwork from past roof work
- Jot down any questions you want answered
- Make sure pets are kept safely away
Getting a price
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 phone 07833 053749 or email us when you are ready.

Landlord and commercial surveys in Highfield
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on, photos included.
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
What you can safely check yourself
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Common questions in Highfield
Are flat-roofed garages and porches in Highfield worth including?
Frequently, yes, so mention it when you book. Many homes in new towns like Hemel Hempstead have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Is Highfield within the area you cover?
Yes, Highfield is on our map. A small place gets exactly the same survey as a big one.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it and parts may need to be lifted. We will discuss it before we quote.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
When you need someone else
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Leaks from walls, copings or rooflights
- Some conductive membranes
- Carrying out the repair work

Practical tips
Small things make a difference. Our tips:
- Don’t let outlets block
- Test new membranes before covering them
- Let us know about the membrane and build-up if you know it
- Limit access to the roof
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Local flat roofs in Highfield
Highfield is part of Hemel Hempstead, one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Many of those flat roofs have been re-covered over the years, and some may still have older felt. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Historic houses such as Batchwood Hall, about 4.4 miles east, show how far back building around Highfield goes. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan. If you let a flat or house near Hemel Hempstead station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Do you need electronic leak detection in Highfield?
Seams are a common weak point in flat roof waterproofing. A gap that’s hard to see can let water in long before anyone notices.
A survey makes sense if you’ve noticed:
- Water coming in under a flat roof
- Leaks under green or ballasted roofs
- Waterproofing to test before it’s covered
- Holes around roof penetrations
For site and facilities teams at buildings like Yewtree Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
