Useful tips for Hunsdon property owners
There’s plenty you can do without going near the roof. What helps most:
- Get leaks traced quickly
- Clear flat roof outlets regularly
- Stay off the flat roof unless needed
- Share any drawings of the roof
If water has been getting in, insulation under the membrane may be wet. That’s something to discuss with your roofer and other checks can help judge it.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
About our electronic leak detection in Hunsdon
Not every flat roof suits electronic testing. Some membranes conduct electricity themselves, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we’ll 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 can’t give results. Common reasons to book are leaks at pipes, outlets or fixings and gaps at membrane joints, on roof terraces and balconies, single-ply roofs and liquid-applied waterproofing.
Some older homes in villages like Hunsdon 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. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

Hunsdon: your questions answered
Do you cover Hunsdon?
Yes, Hunsdon is within the area we cover. We survey roofs across London and South East England. Just phone 07833 053749 or email us and let us know about the property.
Is Hunsdon within the area you cover?
Yes, we do. Our area covers London and the South East, and smaller places are part of that. Longer journeys are simply planned beforehand.
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, tell us when you book.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Do you look in the roof space?
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.
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take 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 Hunsdon frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The method depends on the membrane and what sits above and below it.
- 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 the survey
- Find any records of previous roof work
- Unlock side gates and any roof access doors
- Tell us where we can park nearby

Advice
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Electronic leak detection around Hunsdon
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Much Hadham Palace, about 3.6 miles north, is one of the historic houses in the wider area around Hunsdon. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Roydon station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Anyone responsible for a site like Hunsdon Junior Mixed and Infant School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If your house is among the older ones in the streets near St Francis Chapel, the flat roofs on later extensions tend to wear out long before the main roof.
