How electronic leak detection works in Rook End
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof before any testing. Telling us what you know about the roof’s membrane and layers helps, like drawings or specifications. It avoids arranging a test that can’t give results. If you’ve noticed holes left by work on the roof and failed seams and laps, we can find out what’s behind it, whatever the roof.
Older buildings in small places like Rook End may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Common roof problems in Rook End
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Signs worth acting on include:
- Leaks at pipes, outlets or fixings
- Leaks under green or ballasted roofs
- Patched roofs that still leak
- Stains far from any visible defect
If you live in an older home near Church of St Mary and All Saints, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before you book
- Whether you can ask questions once you have the report
- Are they insured for the work?
- What the survey won’t cover
- Will they check the loft as well as the outside?
Roof by roof
Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
What we do, step by step
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. The survey typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Rook End often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Jot down any questions you want answered
- Let us know about parking near the property
- If you’re buying, check with the agent that we can get in
Arrange a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please don’t climb up for a closer look. To get started, ring 07833 053749 or email us.

All our prices include VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the exact price before booking.

Our phone lines are open seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or drop us an email.
Why act early in Rook End
A visual inspection can miss tiny holes. ELD picks up breaches a visual check might miss, on suitable membranes. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

FAQs for Rook End
Do you cover smaller places like Rook End?
Yes, Rook End is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Rook End listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can you find leaks on a covered flat roof?
It can be possible, depending on the roof. What sits on the membrane affects the method so we look at the roof first.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
How much does electronic leak detection cost?

Electronic leak detection around Rook End
The wider area around Rook End has a long history of building, with Horham Hall about 2.9 miles south-east. 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.

Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building such as Joyce Frankland Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Newport (Essex) station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
