On inverted roofs, insulation sits above the membrane, which affects testing.
Electronic leak detection in Tower Hill: what you get
Our ELD testing covers flat roofs in Tower Hill and the rest of London and South East England. A visit typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. We quote electronic leak detection for each roof, as the method and time depend on the roof. The results come in a written report with photos. We’re often asked to look into breaches hidden under paving or planting and damp inside with no sign on the roof, across green roofs, liquid-applied waterproofing and flat roof membranes.
In a small place like Tower Hill, 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. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
We write the report in plain English, so you don’t need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Checking the roof from ground level
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book and it will help the survey.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Common roof problems in Tower Hill
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
A survey can pick up problems such as:
- New roofs to check before paving or planting
- A flat roof leak that cannot be traced
- Leaks under green or ballasted roofs
- Breaches around outlets and penetrations
For landlords with property near Hemel Hempstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Choosing a roof surveyor
- Whether you can ask questions once you have the report
- Their insurance cover
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included
Tower Hill: your questions answered
Do you cover smaller places like Tower Hill?
Yes. Tower Hill is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Do you cover Tower Hill?
Yes, Tower Hill is within the area we cover. Our area covers London and the South East. You can phone 07833 053749 or send us an email with the address and some details.
What’s the best way to book?
To book, ring 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
How do you choose the testing method?
We choose the method that suits the roof. You will know which method we plan to use before we start.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
How is ELD priced?
We quote for each roof individually. Tell us about the roof and where it leaks, and call 07833 053749 or send us an email for a quote.
Leave it or get it looked at?
Some breaches are too small to see. Electronic testing can find breaches you can’t see by eye, on suitable membranes. Where a roof is exposed, as many are in small places like Tower Hill, driving rain gets into any weakness, and damp in older walls is slow to dry out.
To find out what your survey will cost, call 07833 053749 or drop us an email and tell us about the roof. The price is agreed before a date is set.
What you get with us
- An independent look at the roof
- Surveys seven days a week
- Every finding written up with photos
- Drones and thermal imaging where it applies
Flat and commercial roofs around Tower Hill
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Chenies Manor House, about 2.8 miles south-west, is one of the historic houses in the wider area around Tower Hill. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church such as Church of St Paul are often among the oldest in a place, and if you own one of the older houses nearby, the joins between later flat roofs and the old walls are where problems normally start. For site and facilities teams at buildings such as Kings Langley School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Tower Hill is about 3 miles south-west of Hemel Hempstead, in Hertfordshire. Roofs in Tower Hill get the same thorough look as anywhere else in Hertfordshire. We cover towns and villages across Hertfordshire, large and small. There is also a page for London.

What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect longer on a large roof than a small one, with the construction of the roof playing a part too. Older roofs in small places like Tower Hill can have low, tight loft spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Preparing for the visit
- Clear the way to the loft hatch
- Leave side gates unlocked
- Agree roof access with the managing agent if it’s shared
How to book
Most bookings start with a short call: ring 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
