Electronic leak detection in Nalderswood: local notes
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. 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 check with the council. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Horsham stone slab roofs survive on some old buildings in Surrey. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own a rental within reach of Salfords station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a building such as Burys Court School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you live in an older home near Church of St Bartholomew, the flat roofs on later extensions tend to wear out long before the main roof.

Electronic leak detection for homes and businesses in Nalderswood
Some flat roofs cannot be tested electronically. 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 will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. If you’ve noticed leaks showing away from the breach and punctures from foot traffic or tools, a survey will tell you what’s going on.
In a village or hamlet like Nalderswood, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Why get it checked now?
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Older and listed buildings around Nalderswood may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

- Leaks from walls, copings or rooflights
- Build-ups without a suitable layer below
- Fixing the holes we find

Practical tips
Nothing here needs a ladder. A few suggestions:
- Do not keep patching the same spot
- Keep foot traffic on flat roofs to a minimum
- Tell us about the membrane and build-up if you know it
- Ask contractors to protect the membrane
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Limit foot traffic on flat roofs. Many breaches come from foot traffic.
Common questions in Nalderswood
Will you come out to Nalderswood?
Yes. Nalderswood is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Just mention lanes, gates or anything else about the route when booking.
Does a conservation area affect roof work in Nalderswood?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you look in the loft space?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. For a quote, ring 07833 053749 or drop us an email.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Do you climb onto every roof?
Only if it is safe. We inspect whatever is safely visible: from the ground, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. Anything we cannot see is noted in the report.
How long will testing take?
It depends on the size of the roof and its build-up. We will give you an idea when we quote.

What happens on the day
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. 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. Older rural homes like those around Nalderswood can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen, and anything we cannot see is noted.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive
- Have any paperwork from past roof work to hand
- Let us know where we can park nearby
- Have any questions written down, so nothing gets missed
