Electronic leak detection for homes and businesses in Hammer Bottom
Water can travel under a flat roof membrane before it shows inside. That makes leaks hard to trace by eye. ELD tests the waterproofing directly and locates the breach. We test and report, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. Typical surveys look at breaches around outlets and penetrations and damp inside with no sign on the roof, on roof terraces and balconies, green roofs and commercial flat roofs.
Flat roofs on exposed homes in small places like Hammer Bottom 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, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we look at the roof.
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where applicable.

Hammer Bottom: your questions answered
Is Hammer Bottom in the area you cover?
We do. The survey and report are the same in Hammer Bottom as anywhere else, and visits run on weekdays and weekends.
Is Hammer Bottom within the area you cover?
Yes. Hammer Bottom is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Is my roof suitable for ELD?
ELD does not suit every roof. Some membranes conduct electricity and some roofs lack the layer the test needs. We will tell you if yours is not suitable at the start.
What’s the best way to book?
Just phone 07833 053749 or drop us an email. We will ask a few questions, confirm the price and agree a date.
How is ELD priced?
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, call 07833 053749 or send us an email.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too.
Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Keep foot traffic on flat roofs to a minimum
- Keep outlets clear of debris
- Don’t leave water getting in
- Use boards when working on the roof
After your roofer repairs the breaches, a retest can confirm them if the build-up allows.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
Do you need electronic leak detection in Hammer Bottom?
Water travels under flat roof membranes. The leak may show some distance from where water gets in, so tracing it by eye is difficult.
These are some of the problems a survey can pick up:
- Leaks through a flat roof with no obvious cause
- Leaks under green or ballasted roofs
- Holes left by work on the roof
- Leaks showing away from the breach
For landlords with property near Haslemere station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Why act early in Hammer Bottom
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Outbuildings and barns around Hammer Bottom 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.
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 booking.

What happens on the day
After the inspection, everything we found is written up as a photo-illustrated written report, emailed to you. 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. Somewhere as small as Hammer Bottom, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- 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.
Preparing for the visit
- Unlock side gates and any roof access doors
- Make sure the loft hatch can be reached
- Show us where any leaks or stains appear

Electronic leak detection in Hammer Bottom: local notes
What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. 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. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take a building like Woolmer Hill School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you live in an older home near The Parish Church of St Peter, flat-roofed rear additions and dormers added over the years are worth checking.
