How electronic leak detection works in High Cross
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. Repair costs are not part of the report; that’s for your roofer to price. 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. Common reasons to book are new membranes needing a check before handover and leaks at pipes, outlets or fixings, on commercial flat roofs, flat roof membranes and single-ply roofs.
Flat roofs on exposed homes in small places like High Cross take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Where we can’t see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t.

Flat and commercial roofs around High Cross
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 4.2 miles east lies Much Hadham Palace, a reminder of how long the area around High Cross has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you live in an older home near Church of St John the Evangelist, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you look after a building like Thundridge Church of England Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you let a flat or house near Ware station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Different roofs, different checks
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but can still be punctured.
Checking the roof from the ground
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
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.
Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Keep a note of leaks after rain
- Test new membranes before covering them
- Don’t let outlets block
- Have roof specifications to hand
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
FAQs for High Cross
How do I find out if my home in High Cross is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you cover High Cross?
Yes, High Cross is one of the places we work. Every survey there gets the same written report with photographs.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
How soon will I get the report?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What insurance do you have?
We hold professional indemnity and public liability insurance.
Does someone need to be in?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we will agree the details as you book.
How it works
Safety comes first on every visit. We inspect everything that’s safely in view, and anything we can’t see is noted in the report. The survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere like High Cross needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Before we arrive
- Tell us about any leaks, stains or damp patches you know of
- If you’re buying, let the agent know when we are coming
- Unlock side gates and any roof access doors
