Penn Street Electronic Leak Detection
Electronic leak detection to pinpoint holes in flat roof membranes across Penn Street, using drones and thermal imaging where it applies. Get in touch for a price.
- New membranes needing a check before handover
- Leaking laps in the waterproofing
- Leaks at pipes, outlets or fixings
Can I check my roof myself?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Electronic leak detection for homes and businesses in Penn Street
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you’re worried about patched roofs that still leak and a flat roof leak that can’t be traced, a survey will tell you what’s going on, whatever the roof.
Somewhere as small as Penn Street, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when you book.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Useful tips for Penn Street property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Stay off the flat roof unless needed
- Record dates and spots where water appears
- Have roof specifications to hand
- Clear flat roof outlets regularly
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Why get it checked now?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. Older cottages and farmhouses around Penn Street can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before you book.

Your questions about electronic leak detection in Penn Street
Is my home in Penn Street listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is Penn Street within the area you cover?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Do you climb onto every roof?
Only if it’s safe. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it’s safe and by drone where it applies. The report says if anything couldn’t be seen.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. Points are put with the most urgent first where relevant.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report. We’ll recommend an engineer if we see signs that call for one.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Can you inspect my roof with a drone?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
What we do, step by step
Once we’ve finished looking, we write up our findings as a written report with photos, emailed to you. On timing, most surveys take longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Penn Street, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- 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.
- The breaches are recorded with photographs in a report for your roofer.
Before we arrive
- Check the loft hatch can be reached
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.

Flat roofs in Penn Street
Some villages in Buckinghamshire still have thatched roofs. 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. Historic houses like Hughenden Manor, about 4.1 miles west, show how far back building in the area around Penn Street goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Curzon Church of England Combined School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Amersham station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. For an older house near a landmark such as Church of the Holy Trinity, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
