About our electronic leak detection in Liss Forest
We carry out electronic leak detection on flat roofs in Liss Forest and across London and South East England. A visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. Every roof is quoted on its size and build-up. You get a written report with photographs. We survey liquid-applied waterproofing, commercial flat roofs and single-ply roofs, and the problems we’re asked to look at most are stains far from any visible defect and water coming in under a flat roof.
Flat roofs on exposed homes in small places like Liss Forest take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first, so the repair can be targeted. Outbuildings and barns around Liss Forest are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What happens on the day
After the inspection, everything we found is written up as a written report with photos. As for time on site, it typically takes longer on a large roof than a small one, with the construction of the roof playing a part too.

- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.

Related advice
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Test new membranes before covering them
- Note where leaks show inside and when
- Limit access to the roof
- Act on new leaks promptly
Keep the report with the roof’s records. It’s a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Electronic leak detection around Liss Forest
Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
Anyone responsible for a site like Liss Infant School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you let a flat or house near Liss station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

FAQs for Liss Forest
Is Liss Forest within the area you cover?
Yes. Liss Forest 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 you book.
Does a conservation area affect roof work in Liss Forest?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How long will testing take?
Testing normally takes more time on a big roof than a small one, with the construction of the roof playing a part too.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.

We quote for each roof individually. Send us details of the roof, and ring 07833 053749 or drop us an email for a quote.
What happens next?

It sets out what we found, why it matters and what we recommend, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
When to book a survey in Liss Forest
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Signs worth acting on include:
- Breaches hidden under paving or planting
- Leaks that return after repairs
- Leaks at pipes, outlets or fixings
- Leaking laps in the waterproofing
The streets around a church such as St Saviour's are often among the oldest in a place, and if your house is among the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.
