How electronic leak detection works in Frogmill
Water can travel under a flat roof membrane before it shows inside. So the stain inside rarely sits under the hole. Electronic leak detection tests the membrane itself, to find where it has been breached. We test and report, and the repair is for your roofer. On suitable roofs, it replaces guesswork with a located breach. The results then follow in a written report with photos. If you’ve noticed leaking laps in the waterproofing and waterproofing to test before it’s covered, we can find out what’s behind it.
In a village or hamlet like Frogmill, flat roofs are typically on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when booking.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

Frogmill questions
Do you cover commercial flat roofs around Frogmill?
Yes, commercial buildings, hotels included, are part of the work. Roof access is agreed with the building manager or owner beforehand.
Does a conservation area affect roof work in Frogmill?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Will you walk on the roof?
Only where it is safe to do so. We inspect everything that’s safely in view: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
What happens after the survey?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Is this a RICS survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
How do you choose the testing method?
We choose the method that suits the roof. We will explain why when we quote.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
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.
What we can’t see
A survey is a close look at the flat roof membrane, but it cannot do everything. Its limits include:
- Areas we can’t reach or that can’t be tested
- Build-ups without a suitable layer below
- Fixing the holes we find
If in doubt, phone 07833 053749 or drop us an email and we’ll recommend the right survey before you book. The full list of what we check.
What we check
- Green roofs
- Roof terraces and balconies
- Commercial flat roofs
- Liquid-applied waterproofing
- Single-ply roofs
- Flat roof membranes
Electronic leak detection around Frogmill
About 1 mile north-east lies Harleyford Manor, a reminder of how long the area around Frogmill has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
A roof leak in a hotel or guest house around Frogmill means lost rooms as well as repairs, so it pays to find faults before guests do. If your home is one of the older ones in the streets near Church of St Peter and St Paul, the joins between later flat roofs and the old walls are where problems usually start. Take a building like Danesfield School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Leave it or get it looked at?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.

How the survey works
The aim of the visit is simple: 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 a time that depends on the roof’s area and construction, which we set out in the quote. For a village or hamlet like Frogmill, the journey is planned ahead of time: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
How to prepare
- Tell us where we can park nearby
- Have any paperwork from past roof work to hand
- Leave side gates unlocked
Arrange a survey
A quick phone call is normally the easiest start: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Advice
Tips from our surveys
You don’t need to be a roofer to help. What helps most:
- Tell us about the membrane and build-up if you know it
- Find the breach before more patching
- Note where leaks show inside and when
- Ask contractors to protect the membrane
You receive a report showing where each breach was found, with photographs. Your roofer uses it to carry out repairs.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
