About our electronic leak detection in Theale
ELD finds breaches in the membrane but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You will also know what to check next. If you’re worried about new roofs to check before paving or planting and leaks through a covered membrane, we can find out what’s behind it, on single-ply roofs, flat roof membranes and liquid-applied waterproofing alike.
In smaller places like Theale, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put with the most urgent first where relevant.

DIY checks: what’s safe
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
What we can’t see
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- The extent of water in the insulation
- Roofs whose membrane or build-up is not suitable
- Sections we cannot safely access

FAQs for Theale
How do I find out if my home in Theale is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Theale?
Yes, Theale is one of the places we work. Every survey there gets the same written report with photos.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
How long will testing take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
Flat roofs in Theale
The wider area around Theale has a long history of building, with Mapledurham House about 3.8 miles north-east. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Anyone responsible for a site like Theale C.E. Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If your home is one of the older ones in the streets near Church of the Holy Trinity, the joins between later flat roofs and the old walls are where problems typically start. For landlords with property near Theale station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Theale is about 4 miles west of Reading, in West Berkshire. Whether the building in Theale is a house, a flat or a commercial unit, the roof can be surveyed. Across West Berkshire, we cover Theale.

What we look for on each type of roof
Bituminous membranes
Older felt roofs frequently have seams and patches that can leak. Testing depends on the roof.
Inverted and paved roofs
On inverted roofs, insulation sits above the membrane, which affects testing.

The survey, step by step
Safety comes first on every visit. We inspect what can be seen safely, and anything we cannot see is noted in the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. Homes around Theale frequently have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- Let us know about parking near the property
- Check pets are kept safely away
Booking a survey
Booking is simple: just ring 07833 053749 or email us and give us some details about the property and we’ll recommend the right survey. The price is agreed up front.
