Long Crendon Electronic Leak Detection
Wondering about the flat roof membrane at a property in Long Crendon? We carry out electronic leak detection in Long Crendon and across Buckinghamshire.
- Breaches hidden under paving or planting
- Holes left by work on the roof
- Waterproofing to test before it’s covered
How electronic leak detection works in Long Crendon
ELD can be carried out in more than one way. Low-voltage methods typically need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. We will say if your roof does not suit either method before any testing starts. Typical surveys look at water coming in under a flat roof and patched roofs that still leak, on liquid-applied waterproofing, flat roof membranes and single-ply roofs.
In smaller places like Long Crendon, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let a good many water into the room below. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

How it works
We’ll ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Some parts of a survey depend on the weather, so a visit to Long Crendon is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Leave side gates unlocked
- Note where any stains or damp appear
- Move anything stored under the loft hatch
How to book
We confirm the price for the job before booking, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or use the contact form.
Advice
How the survey changes by roof type
Green and ballasted roofs
Roofs with planting or ballast hide the membrane. Testing may still be possible but it depends on the layers.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
What affects the cost of electronic leak detection
All our prices include VAT. What changes the price is:
- Chimneys, valleys, parapets and other details
- The number of roofs, including extensions and garages
- How tall the building is and how easy the roof is to see
- Whether it is a home or a commercial building
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.
What to tell us when you get in touch
A little information up front helps. Please include:
- Photos of the roof, taken safely from ground level or a window
- Any stains, drips or damp patches you’ve seen indoors
- Whether there’s a loft hatch, a shared roof or tricky access
- The style of property, from a terrace to a block
You can call us seven days a week. To book or ask a question, phone 07833 053749 or email us.

When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:

- Repairing the breaches (that’s for your roofer)
- Roofs whose membrane or build-up is not suitable

Flat and commercial roofs around Long Crendon
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council. Thatch survives on some older buildings in Buckinghamshire’s villages. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you live in an older home near Church of St Mary, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. For site and facilities teams at buildings such as Long Crendon School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Haddenham & Thame Parkway station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Most of what helps is simple and safe from ground level. Our suggestions:
- Do not leave water getting in
- Ask contractors to protect the membrane
- Don’t let outlets block

Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
