What we do, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes longer on a large roof than a small one, with the construction of the roof playing a part too. Around Black Notley, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Let us know about parking near the property
- Let us know about any leaks, stains or damp patches you know of

About our electronic leak detection in Black Notley
Not every flat roof suits electronic testing. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we will tell you at the start. Any details you have about the membrane and build-up help us decide, such as drawings or specifications. It avoids arranging a test that cannot give results. We are often asked to look into leaks at pipes, outlets or fixings and waterproofing to test before it’s covered, on flat roof membranes, roof terraces and balconies and single-ply roofs.
Flat roofs on exposed homes in small places like Black Notley take more wind and rain, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, 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.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

What we look for on each type of roof
Single-ply membranes
Many offices and units have single-ply roofs. Laps and fixings are where holes often appear.
EPDM rubber roofs
Some EPDM membranes conduct electricity which can limit electronic testing. We’ll say if the test won’t work.
Why it’s worth a survey now in Black Notley
Patching where you think the leak is frequently misses it. ELD shows the actual breach points. Matching old materials, such as handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

Prices for electronic leak detection in Black Notley
Prices vary from roof to roof, for these reasons:
- Commercial roofs and larger buildings
- The size of the roof
- How complicated the roof is, with its valleys, chimneys and parapets
- If the survey needs thermal imaging or a drone
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for your survey before booking.
What to let us know when you contact us
Before you get in touch, it is useful to have:
- Anything about access we should know
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
- Any deadline, such as an exchange date
A quick phone call is usually the easiest start: ring 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Can I check my roof myself?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That is where a survey comes in, using safe viewpoints and a drone where it applies.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book and it will help the survey.

Questions from Black Notley
Does a conservation area affect roof work in Black Notley?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you carry out roof surveys in Black Notley?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
What will the report tell me?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
What happens after the survey?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage methods are normally carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Will you check the loft?
If there’s a loft and safe access to it, yes. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
What electronic leak detection looks like in Black Notley
Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, and plenty of post-war and modern estates besides. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If your house is among the older ones in the streets near Church of St Peter and St Paul, the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Braintree Sixth Form will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you let a flat or house near Cressing station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
