- Holes around roof penetrations
- Patched roofs that still leak
About our electronic leak detection in Gaston Green
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. We will tell you if the roof cannot be tested. If you’ve noticed damp inside with no sign on the roof and repairs that haven’t stopped the leak, a survey will tell you what’s going on.
Flat roofs on exposed homes in small places like Gaston Green take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

Gaston Green questions
Will you come out to Gaston Green?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Do you carry out roof surveys in Gaston Green?
We do. Every survey there gets the same written report with photos.
How long will testing take?
Testing usually takes a time that depends on the roof’s area and construction, which we’ll explain when we quote.
Will I get photos?
Yes. Photographs are part of every report.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage testing typically needs a wet surface and high-voltage methods need the membrane dry and exposed.
How many surveys have you done?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
What happens next?
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.
Honest limits
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- Moisture spread under the membrane
- Carrying out the repair work
- Some conductive membranes
If in doubt, call 07833 053749 or email us and we’ll point you to the right survey before booking. What a survey covers and doesn’t.
What this survey covers
- Commercial flat roofs
- Green roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
- Single-ply roofs
- Flat roof membranes
Practical tips
Over many surveys, some simple habits stand out:
- Keep outlets clear of debris
- Let us know about the membrane and build-up if you know it
- Stay off the flat roof unless needed
- Record dates and spots where water appears
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that, and moisture readings can help.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, photograph what we find and make notes for the report. Most visits take longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Gaston Green, access is usually the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know about the roof and where water is showing.

Advice
Flat roofs in Gaston Green
Older buildings in Essex frequently have clay tiles and weatherboarding, with post-war and more recent estates making up much of the newer housing. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Barrington Hall, about 3.2 miles east, show how far back building in the area around Gaston Green goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
If you live in an older home near Church of St Mary the Virgin, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Anyone responsible for a site like Spellbrook CofE Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Sawbridgeworth station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
