About our electronic leak detection in Maple Cross
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or check a new membrane before handover. Each roof is quoted on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays when conditions allow. Just ask about your roof. If you’ve noticed patched roofs that still leak and holes around roof penetrations, we can find out what’s behind it.
Older buildings in small places like Maple Cross may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

Rented homes, blocks and businesses
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Let us know about it when you book and we’ll plan the survey around it.
Landlords, agents and building managers in Maple Cross and across Hertfordshire can book any of our surveys. For a price for a let property or a block, call 07833 053749 or drop us an email.
How the survey works
We photograph the roof as we go, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In a small place like Maple Cross, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Leave side gates unlocked
- If the roof is shared, arrange access with whoever manages the building
- Keep pets inside or away from the areas we’re looking at
Getting a price
A quick phone call is typically the easiest start: call 07833 053749 or use the contact form and we’ll ask a few questions about the roof. The price is agreed before a date is set.

Flat roofs in Maple Cross
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Historic houses such as Chenies Manor House, about 3.7 miles north, show how far back building in the area around Maple Cross 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.
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 site and facilities teams at buildings such as Maple Cross Junior Mixed Infant and Nursery School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. Take an older house close to Church of St Thomas of Canterbury: the joins between later flat roofs and the old walls are where problems normally start.
Maple Cross is about 2 miles south-west of Rickmansworth, in Hertfordshire. Maple Cross is one of many places we visit across Hertfordshire, for homes and businesses alike. We cover towns and villages across Hertfordshire, large and small. London is in our area too.

How the survey changes by roof type

Why get it checked now?
Testing a new membrane before it is covered is easier than tracing a leak later. Once layers are added, finding a breach is harder. Older cottages and farmhouses around Maple Cross can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.

Maple Cross questions
Will you come out to Maple Cross?
Yes, Maple Cross is covered. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
How do I find out if my home in Maple Cross is listed?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is my roof suitable for ELD?
ELD doesn’t suit every roof. Some membranes conduct electricity, and some build-ups lack a suitable layer below. If your roof won’t work, we will say so at the start.
What will the report tell me?
You get our findings in writing, part by part, with photos. The most urgent items are made clear.
Which method do you use?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
What happens next?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you walk on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
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.
