Flat and commercial roofs around Clapgate
Historic houses such as Much Hadham Palace, about 3.4 miles south, show how far back building in the area around Clapgate goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
The streets around a church such as Church of St Mary are often among the oldest in a place, and if your house is among the older ones nearby, the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Albury Church of England Voluntary Aided Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

About our electronic leak detection in Clapgate
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. Typical surveys look at damp inside with no sign on the roof and breaches hidden under paving or planting, on roof terraces and balconies, liquid-applied waterproofing and single-ply roofs.
Some older homes in villages like Clapgate are listed or in a conservation area, which can shape what a new flat roof may look like. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report is written in plain words, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put in order of urgency where relevant.

Questions from Clapgate
How do I find out if my home in Clapgate is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Clapgate?
We do. Every survey there gets the same written report with photographs.
Will you check the loft?
If there’s a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it, and some may need lifting. We will discuss it before we quote.
Is the repair part of the test?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Which method do you use?
We choose the method that suits the roof. You will know which method we plan to use before we start.
Will you go up on the roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where applicable let us see the rest.
Do you need electronic leak detection in Clapgate?
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs, depending on the build-up.
Look out for signs like these:
- Punctures from foot traffic or tools
- Water coming in under a flat roof
- Damp inside with no sign on the roof
- Waterproofing to test before it’s covered
Landlords with a home close to Bishops Stortford station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
What to check before booking
- What the report includes, and whether it has photos
- How long they’ve been surveying roofs
- How long the report takes to arrive
- How they plan to inspect the roof safely
The survey, step by step
After the inspection, everything we found is written up in a report with photos. As for time on site, it normally takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. Rural addresses near Clapgate can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- Note where any stains or damp appear
- Let us know about parking near the property
- If you’re buying, let the agent know when we are coming

Should I look at the roof myself first?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.

Booking your survey
A little information up front helps. Please include:

- Your timetable, such as an exchange date
- What kind of property and roof it is

Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Do not leave water getting in
- Share any drawings of the roof
- Note where leaks show inside and when
- Find the breach before more patching
Wet insulation may need attention after a leak. That is something to discuss with your roofer, and moisture readings can help.
ELD before paving, ballast or planting goes on is worth considering. It’s easier to find holes before more layers are added.
