About our electronic leak detection in Grazeley
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. We survey flat roof membranes, liquid-applied waterproofing and green roofs, and people most often book us about new membranes needing a check before handover and failed seams and laps.
In a village or hamlet like Grazeley, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included as you book.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put in order of urgency where relevant.

What we look for on each type of roof
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes frequently appear.
When you need someone else
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Moisture spread under the membrane
- Build-ups without a suitable layer below
- Areas we can’t reach or that cannot be tested

Grazeley questions
Do you carry out roof surveys in Grazeley?
Yes, Grazeley is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is Grazeley within the area you cover?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are typically carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
How fast do I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
What happens after the survey?
You will receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Do you look in the loft space?
Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps.
The survey, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere as small as Grazeley, access is frequently 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.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Find any records of previous roof work
- Jot down any questions you want answered
- Keep pets out of the way during the survey

What electronic leak detection looks like in Grazeley
With Stratfield Saye House about 3.3 miles south, Grazeley sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings like Grazeley Parochial Church of England Aided Primary School, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. For an older house near a landmark like Holy Trinity Church, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Grazeley is about 4 miles south of Reading, in West Berkshire. Wherever you are in Grazeley, we can come and survey your property. Across West Berkshire, we cover Grazeley and the places around it.
All of RG7 is within our area for electronic leak detection. Whether your property is on Mereoak Lane, Church Lane and Mortimer Road or anywhere close by, we can survey it.

Well-known places in the area include Thames Valley Police Museum (3.9 miles north-west) and Beaumys Castle (1.5 miles south-east). The countryside around Grazeley includes Fobney Island Wetland Reserve and Longwater.
What you can safely check yourself
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Why get it checked now?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. For an older or listed building in a place like Grazeley, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
