What we look for on each type of roof
Bituminous membranes
Bitumen roofs can frequently be tested electronically, depending on what’s below.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Electronic leak detection in Wyddial
You get a report showing the location of each breach, with photos. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs, so your roofer prices the work. A retest after repairs can check the work if the build-up allows. You get a photo-illustrated written report. Common reasons to book are waterproofing to test before it’s covered and breaches around outlets and penetrations, across flat roof membranes, commercial flat roofs and single-ply roofs.
In a small place like Wyddial, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
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.

Wyddial: your questions answered
Does a conservation area affect roof work in Wyddial?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover smaller places like Wyddial?
Yes, Wyddial is covered. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, phone 07833 053749 or use the contact form.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
Will you check the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
Tips from our surveys
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Tips:
- Have roof specifications to hand
- Act on new leaks promptly
- Do not let outlets block
- Use boards when working on the roof
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Clear flat roof outlets regularly. Water that sits on the roof finds breaches faster.
Signs you need electronic leak detection in Wyddial
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Things that often lead to a survey include:
- Leaking laps in the waterproofing
- New membranes needing a check before handover
- Leaks that return after repairs
- Holes left by work on the roof
If your house is among the older ones in the streets near Church of St Giles, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

What this survey cannot tell you
Before booking, it is worth knowing what a survey will not do:
- Moisture spread under the membrane
- Fixing the holes we find
- Water entering through details rather than the membrane

Electronic leak detection around Wyddial
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. England has around 10,000 conservation areas and about 500,000 listed buildings. If your 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, so check with the council.
Take a building like Layston Church of England First School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Prices for electronic leak detection in Wyddial
Prices vary from roof to roof, for these reasons:
- Chimneys, valleys, parapets and other details
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages
- The use of thermal imaging or a drone
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
Getting in touch
These details help when you contact us:
- Photos of the roof, taken safely from ground level or a window
- What kind of property and roof it is
- Your timetable, like an exchange date
- The address and postcode of the property
Every survey is priced before it is booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or send us an email.
What happens on the day
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit typically takes as long as needed for the roof’s area and construction, which we set out in the quote. Somewhere as small as Wyddial, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- 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 we arrive
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear
- Have keys ready for side gates, garages or roof access doors
