Flat and commercial roofs around Loyter's Green
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, while many towns grew with post-war and newer estates. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Harlow Mill station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.

How electronic leak detection works in Loyter's Green
There are different ELD methods. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. The right method depends on the membrane and the build-up of the roof and we explain which we will use. We will say if your roof does not suit either method before any testing starts. We survey commercial flat roofs, single-ply roofs and flat roof membranes, and common reasons people get in touch are leaks through a covered membrane and leaks showing away from the breach.
Older buildings in small places like Loyter's Green may be 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. Changes that affect a listed building’s special interest need listed building consent.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

Before and after the survey
Here are a few things we’d tell any owner:
- Act on new leaks promptly
- Find the breach before more patching
- Keep a note of leaks after rain
- Use boards when working on the roof
Wet insulation may need attention after a leak. Your roofer can advise on that, and moisture readings can help.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
What you can safely check yourself
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The survey, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit normally takes as long as needed for the membrane area and the build-up, and we’ll give you a guide when quoting. Cottages and farmhouses around Loyter's Green often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Preparing for the visit
- Note where any stains or damp appear
- Keep pets inside or away from the areas we are looking at
- Jot down any questions you want answered

Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, call 07833 053749 or send us an email.

Common roof problems in Loyter's Green
On a flat roof, water spreads under the waterproofing. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
These are some of the problems a survey can pick up:
- Leaks through a covered membrane
- A flat roof leak that cannot be traced
- Leaking laps in the waterproofing
- Leaks that return after repairs
If your house is among the older ones in the streets near Parish Church of St Mary Magdalen, the joins between later flat roofs and the old walls are where problems usually start.
