What affects the price in Long Green
What a survey costs depends on the time and equipment it needs. The main factors are:
- The size of the roof
- How tall the building is and how easy the roof is to see
- Chimneys, valleys, parapets and other details
- Commercial roofs and larger buildings
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for the job before booking.
What to tell us when you get in touch

- The type of building and roof, like pitched or flat

Electronic leak detection in Long Green: what you get
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a report with photographs of each breach found. Typical surveys look at stains far from any visible defect and breaches hidden under paving or planting, across single-ply roofs, green roofs and flat roof membranes.
In a small place like Long Green, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Signs you need electronic leak detection in Long Green
A breach can be left during installation. Testing before the roof is covered or handed over helps find them.
Look out for signs like these:
- Breaches hidden under paving or planting
- New roofs to check before paving or planting
- Breaches around outlets and penetrations
- Damp inside with no sign on the roof
For site and facilities teams at buildings like Cressing Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Flat roofs in Long Green
In Essex, older buildings are frequently clay-tiled, many with weatherboarding, alongside lots of post-war and newer estates. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
If you let a flat or house near Braintree Freeport station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark such as St Barnabas, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

- Repairing the breaches (that is for your roofer)
- Some conductive membranes
- Water entering through details rather than the membrane

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Find the breach before more patching
- Note where leaks show inside and when
- Check new waterproofing before handover
- Don’t leave water getting in
If anything in the report isn’t clear, ask us. We will explain what was found and what it means.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
Should I look at the roof myself first?
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.
What you cannot do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
FAQs for Long Green
Is my home in Long Green listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is Long Green in the area you cover?
Yes, Long Green is one of the places we work. The survey and report are the same in Long Green as anywhere else.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
How much time does ELD need?
It typically takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote.
Do you use drones?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
When does the report arrive?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, let us know when booking.

What happens on the day
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. In a hamlet or village like Long Green, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- If you are buying, let the agent know when we’re coming
- Keep pets inside or away from the areas we are looking at
- Gather any invoices or paperwork from past roof work
