About our electronic leak detection in Tyttenhanger
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. If you’ve noticed holes around roof penetrations and water coming in under a flat roof, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Tyttenhanger, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report works through the roof section by section, from the coverings down to the gutters. It records what’s sound as well as what isn’t.

What electronic leak detection looks like in Tyttenhanger
Historic houses such as Batchwood Hall, about 3.3 miles north-west, show how far back building in the area around Tyttenhanger goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Church of St Mark, the joins between later flat roofs and the old walls are where problems typically start. If you look after a building such as Nicholas Breakspear School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of St Albans station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Tyttenhanger is about 2 miles south-east of St Albans, in Hertfordshire. In Tyttenhanger, as across Hertfordshire, every roof gets the same careful survey. Our Hertfordshire coverage includes Tyttenhanger and the places around it. We also survey roofs in London.

What affects the price in Tyttenhanger
All our prices include VAT. What changes the price is:

- The type of building, from a house to a block or an office
- Whether thermal imaging or a drone is needed
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.

The more you let us know, the easier it is to price the survey. When you contact us, let us know:

- The reason for the survey, like buying, a leak or storm damage
- When you need the report by
- Pictures from the garden or a window, if you have them

For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps when budgeting.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Let us know about it when booking and we’ll plan the visit with that in mind.
Your questions about electronic leak detection in Tyttenhanger
Is Tyttenhanger within the area you cover?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Is my home in Tyttenhanger listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Does ELD include fixing the breach?
No. We test the membrane and report. You get the breach locations with photos so your roofer can fix them.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed.
How much time does ELD need?
Testing typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote.
What if it rains on the day?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.

Tips from our surveys
From years of surveys, a few habits stand out as worth the effort:
- Stay off the flat roof unless needed
- Keep outlets clear of debris
- Share any drawings of the roof
- Avoid repeated repairs without finding the cause
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Do not leave a flat roof leak running. Water under a membrane can spread.
Different roofs, different checks
Green and ballasted roofs
Some layers may need lifting for testing. We explain what’s needed when we quote.
Liquid-applied waterproofing
Liquid waterproofing has no laps but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
Why act early in Tyttenhanger
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first, so the repair can be targeted. Outbuildings and barns around Tyttenhanger are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

What we do, step by step
The visit has one job: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Tyttenhanger, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- 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.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Before we arrive
- Point out any leaks or damp patches
- Let us know about parking before the day
- Agree roof access with the managing agent if it’s shared
How to book
A quick phone call is normally the easiest start: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.
