The survey, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a small place like Hatfield Broad Oak, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Let us know about any leaks, stains or damp patches you know of

Electronic leak detection in Hatfield Broad Oak: what you get
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Tell us about your roof to find out more. We survey single-ply roofs, green roofs and commercial flat roofs, and people most frequently book us about holes around roof penetrations and patched roofs that still leak.
In a small place like Hatfield Broad Oak, a flat roof can stand in the open, 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, so you can plan your next steps.

Useful tips for Hatfield Broad Oak property owners
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Do not let outlets block
- Consider ELD before paving or planting goes on
- Keep a note of leaks after rain
- Have roof specifications to hand
After your roofer repairs the breaches, a retest can confirm them, where the roof still suits the method.
Do not leave a flat roof leak running. The longer water gets in, the more insulation and decking can be affected.
What we look for on each type of roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.

Why act early in Hatfield Broad Oak
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 Hatfield Broad Oak, older homes often have old roof timbers, where water from a failed roof can cause rot if it’s left.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.

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.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.

How much time does ELD need?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Is it a structural engineer’s report?
No. We point out what can be seen, like sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
What does electronic leak detection do?
It uses an electrical current to find breaches in a flat roof membrane. The current only gets through where the membrane is breached so we can pinpoint it.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.

Weatherboarded walls and clay tile roofs are typical of older Essex buildings, with post-war and more recent estates making up much of the newer housing.
