FAQs for Loudwater
How do I find out if my home in Loudwater is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Is Loudwater in the area you cover?
Yes. Our area covers London and the South East, and Loudwater is part of that. You can phone 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
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. Anything we can’t see is noted in the report.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
What does the report include?
It sets out what we found, why it matters and what we recommend, with photographs throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, ring 07833 053749 or email us.
What if it rains on the day?
Light rain doesn’t usually stop a survey. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
Electronic leak detection in Loudwater: what you get
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at 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 are worried about gaps at membrane joints and damp inside with no sign on the roof, a survey will tell you what’s going on, on liquid-applied waterproofing, commercial flat roofs and single-ply roofs alike.
Flat roofs on exposed homes in small places like Loudwater take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically 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.
Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

What else we do in Loudwater
Tips that help
Small things make a difference. Some pointers:
- Do not let outlets block
- Stay off the flat roof unless needed
- Keep a note of leaks after rain
- Check trades protect the waterproofing
Where the evidence points to walls, copings or rooflights, we will note it, so other causes can be checked.
Ask trades working on the roof to protect the membrane when they work up there. Check the roof after they’ve finished.
Can I check my roof myself?
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Surveys for landlords and agents in Loudwater
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on any day of the week, which helps when tenants work during the week.
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
How the survey works
We don’t take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof can’t be seen, the report says so. The survey typically takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Around Loudwater, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photos in a report for your roofer.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear
- Check pets are kept safely away

What electronic leak detection looks like in Loudwater
The wider area around Loudwater has a long history of building, with Chenies Manor House about 2.5 miles north-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For site and facilities teams at buildings such as Christ Church Chorleywood CofE School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For landlords with property near Rickmansworth station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For businesses in and around places such as Charter Place, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

What a survey costs

- Whether thermal imaging or a drone is needed
- Extensions, dormers and garages with roofs of their own
- How complicated the roof is, with its valleys, chimneys and parapets
- The roof’s overall size
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Electronic leak detection is quoted for your roof, because the method depends on the roof.
