How electronic leak detection works in Brewer Street
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an 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 knows exactly where to repair. The results come in a report with photos. If you’re worried about punctures from foot traffic or tools and new roofs to check before paving or planting, a survey will tell you what’s going on, whatever the roof.
Some older homes in villages like Brewer Street are 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.
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.

Checking the roof from ground level
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Do you need electronic leak detection in Brewer Street?
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
Most people get in touch when they’ve noticed one of these:
- Stains far from any visible defect
- Breaches hidden under paving or planting
- Gaps at membrane joints
- New roofs to check before paving or planting
Take a building like Bletchingley Village Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- Whether the roof space is looked at, where there is one
- What the report includes, and whether it has photos
- Whether they hold professional indemnity and public liability insurance
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What we do, step by step
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. In a small place like Brewer Street, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with what you know about the roof and the leak.
- 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.
- A report with photographs shows where each breach is.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Leave a clear route to the loft
- Buyers: confirm access with the estate agent or seller

What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Whether it is a home or a commercial building
- The height of the building and how the roof can safely be seen
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.
Getting in touch
The more you tell us, the easier it is to price the survey. When you get in touch, it’s useful to mention:
- Photos of the roof, taken safely from ground level or a window
- Access details, like a loft hatch or a shared roof
- Any marks or damp showing indoors
- What’s prompted the survey
Every survey is priced before it’s booked, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or drop us an email.
What we look for on each type of roof
Bituminous membranes
Bituminous roofs often have laps and old repairs that can leak. Testing depends on the roof.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Landlords, agents and block managers in Brewer Street
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we’ll plan the survey around it.
Flat roofs in Brewer Street
Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list, before anyone quotes for re-roofing. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For businesses in and around places such as The Belfry, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you live in an older home near Church of St Mary the Virgin, flat-roofed rear additions and dormers added over the years are worth checking.
