How electronic leak detection works in St Helens
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. If you’ve noticed punctures from foot traffic or tools and damp inside with no sign on the roof, we can find out what’s behind it, on liquid-applied waterproofing, flat roof membranes and single-ply roofs alike.
Flat roofs on exposed homes in small places like St Helens take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. It is useful right away, and a good reference for later.

How we price electronic leak detection
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- Extra roofs, like extensions, dormers or garages
- How tall the building is and how easy the roof is to see
- Any need for thermal images or a drone flight
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for the job before you book.

These details help when you contact us:

Electronic leak detection around St Helens
The coast is about 2 miles or less from St Helens, where sea air brings more salt and stronger wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Yaverland Manor, about 2.1 miles south-west, is one of the historic houses in the wider area around St Helens. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings such as St Helens Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For landlords with property near Brading station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What happens if roof problems are left?
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. Older cottages and farmhouses around St Helens 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.

Common roof problems in St Helens
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole which makes it hard to find by looking.
We’re frequently asked to look at:
- Stains far from any visible defect
- Leaks through a flat roof with no obvious cause
- Damage from equipment installers
- Gaps at membrane joints
Take an older house close to St Catherine-by-the-Green: flat-roofed rear additions and dormers added over the years are worth checking.
Before you book any roof surveyor
- Will they check the loft as well as the outside?
- Whether any drone flown is registered with the CAA
- What exactly goes into their report
- What happens after the report arrives
Can I check my roof myself?
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book and it will help the survey.
Tips from our surveys
Most of what helps is simple and safe from the ground. A few suggestions:
- Test new membranes before covering them
- Record dates and spots where water appears
- Keep foot traffic on flat roofs to a minimum
- Check trades protect the waterproofing
Questions about the results are welcome. We will explain what was found and what it means.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
How it works
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can safely be seen. Most surveys take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around St Helens often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Tell us about any leaks, stains or damp patches you know of
- Unlock side gates and any roof access doors

FAQs for St Helens
Do roofs near the sea, like those around St Helens, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch, and St Helens is within about 2 miles of the coast.
Do you cover smaller places like St Helens?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
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.
Does someone need to be in?
Not always. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime. Let us know your preferred days as you book.
What does the report include?
It works through the roof part by part, in writing and with photos. Points are put in order of urgency where relevant.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
