About our electronic leak detection in Rableyheath
There are different ELD methods. Low-voltage testing is typically done with the surface wet, while high-voltage testing needs a dry, exposed membrane. Which one suits depends on the membrane and the layers of the roof and we explain which we will use. If neither method suits your roof, we’ll tell you before any testing starts. We are often asked to look into damp inside with no sign on the roof and repairs that haven’t stopped the leak, on green roofs, liquid-applied waterproofing and commercial flat roofs.
In a village or hamlet like Rableyheath, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

How the survey works
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. It normally takes as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. In a small place like Rableyheath, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- 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

FAQs for Rableyheath
Do you cover smaller places like Rableyheath?
Yes, Rableyheath is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
How do I find out if my home in Rableyheath is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will I get photos?
Yes. Photos are taken throughout the survey, and they go into the written report.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs.
Which days do you carry out surveys?
Surveys run on weekdays and at weekends. To arrange a date, ring 07833 053749 or email us.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
How long will testing take?
It typically takes more time on a big roof than a small one, with the construction of the roof playing a part too.
Do you need electronic leak detection in Rableyheath?
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
These are some of the problems a survey can pick up:
- Failed seams and laps
- Leaks through a flat roof with no obvious cause
- Damage from equipment installers
- New roofs to check before paving or planting
Shop and office owners around Howard Centre may find that the flat roofs over shops and commercial units are worth checking before a leak, not after.
Questions to ask before you book
- Whether the price includes VAT
- Whether the inside of the roof is included
- Whether any drone flown is registered with the CAA
- How they plan to inspect the roof safely
Practical tips
A survey works best with a little help from you, before and after. Tips:
- Don’t leave water getting in
- Have roof specifications to hand
- Ask contractors to protect the membrane
- Record dates and spots where water appears
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Check contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
What we can’t see
In fairness, a roof survey has limits:
- Roofs whose membrane or build-up isn’t suitable
- How wet the insulation is
- Repairing the breaches (that is for your roofer)

Electronic leak detection around Rableyheath
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Rableyheath has a long history of building, with Knebworth House about 1.4 miles north-west. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
If you own a rental within reach of Knebworth station, the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church such as Church of St Michael and All Angels are frequently among the oldest in a place, and if yours is one of the older homes nearby, the joins between later flat roofs and the old walls are where problems normally start.
