For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant, which helps with budgets and planning.
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which can make access easier.
Electronic leak detection for homes and businesses in Nether Wallop
There are different ELD methods. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we will use. If neither method suits your roof, we’ll tell you before any testing starts. If you’ve noticed holes left by work on the roof and leaks under green or ballasted roofs, we can find out what’s behind it.
In a village or hamlet like Nether Wallop, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when booking.
Where we cannot see part of the flat roof membrane, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

The survey, step by step
On the day, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. Around Nether Wallop, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- 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.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Keep pets inside or away from the areas we are looking at
- Let us know about parking near the property

What happens if roof problems are left?
Testing a new membrane before it’s covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Around Nether Wallop, older homes often have old roof timbers, and water through a failed covering can rot timber if it is left.

Common questions in Nether Wallop
How do I find out if my home in Nether Wallop is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you carry out roof surveys in Nether Wallop?
Yes, Nether Wallop is within the area we cover. Our area covers London and the South East. Just phone 07833 053749 or send us an email and tell us about the property, and we will talk through which survey suits.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put by urgency where it matters.
What do I do with the report?
You receive the written report by email, with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How do you choose the testing method?
The roof decides the method. We will explain why when we quote.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like 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’s disturbed.
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Keep outlets clear of debris
- Tell us about the membrane and build-up if you know it
- Test new membranes before covering them
- Note where leaks show inside and when
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Consider testing a new membrane before it’s covered. Finding breaches is simpler at that stage.
Roof by roof
Green and ballasted roofs
Green roofs and ballasted roofs cover the waterproofing. Some methods can work through these layers, depending on the build-up.
Liquid-applied waterproofing
Pinholes in a coating can let water through. Where the roof suits it, testing can find them.
What electronic leak detection looks like in Nether Wallop
A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. 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. 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.
The streets around a church such as Church of St Andrew are often among the oldest in a place, and if your home is one of the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. For site and facilities teams at buildings like Wallop Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you let a flat or house near Grateley station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

DIY checks: what’s safe
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
