Electronic leak detection in Ware, Hertfordshire
Find out what’s going on with the flat roof membrane before you decide what to do next. We carry out electronic leak detection in Ware.
- Water coming in under a flat roof
- Leaking laps in the waterproofing
- Holes left by work on the roof
What we do, step by step
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Notes and photographs go into the written report. It usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. For a visit in Ware, we need access to the loft, any rooms with leaks or stains, and the outside of the building. Mention gates, side passages and anything at the back. Visits can be on weekdays, Saturdays or Sundays.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Getting ready for the survey
- Mention any parking restrictions on your street
- Check pets are kept safely away
- Gather any invoices or paperwork from past roof work

Electronic leak detection in Ware: what you get
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. Common reasons to book are leaks showing away from the breach and patched roofs that still leak, across green roofs, commercial flat roofs and roof terraces and balconies.
Shops, surgeries, schools and small business units in towns like Ware often have flat roofs. They’re easy to forget until water comes through a ceiling tile, and by then the insulation underneath may be wet. A survey, or electronic testing where the membrane suits it, shows what’s going on. Tell us who manages the building so access to the roof can be arranged.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photo. You will see the good as well as the bad.

What a survey costs
To price your survey, we check:
- Whether thermal imaging or a drone is needed
- The shape of the roof and its details
- Roof area
- Building height and the viewpoints available
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.
What we need to know
When you call or email, these details help:
- How the loft is reached, if there is one
- The kind of building and roof involved
- Any stains, drips or damp patches you’ve seen indoors
- Where the property is, with the postcode
We confirm the price for your roof before you book, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, phone 07833 053749 or use the contact form.
What happens if roof problems are left?
Some flat roof leaks come from walls or details. ELD helps rule the membrane in or out, so other causes can be checked. Once water reaches the loft insulation in a home in Ware, it loses much of its value and is slow to dry. That’s an extra cost on top of the roof work itself.
For a price for your roof in Ware, phone 07833 053749 or email us with the address and a few details. The price is agreed before a date is set.

Electronic leak detection in Ware: local notes
An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For landlords with property near Ware station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings such as Christ Church CofE (VA) Primary School and Nursery, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

FAQs for Ware
How should I get ready for a visit in Ware?
It helps to clear access to the loft, and to let us know about leaks, damp patches or recent work. Parking and access details for Ware help us plan the visit.
Is Ware in the area you cover?
Yes, Ware is one of the places we work. The survey and report are the same in Ware as anywhere else.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
How long will testing take?
It depends on the size of the roof and its build-up. We’ll give you an idea when we quote.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
What do I do with the report?
We email you the written report with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How does ELD work?
A sound membrane blocks the test current, so wherever there’s a hole, it passes through. That is how we locate breaches you cannot see.
Common roof problems in Ware
Seams are a common weak point in flat roof waterproofing. Small openings at laps can leak for months before it shows.
People normally book a survey when they’ve noticed something like this:
- Breaches hidden under paving or planting
- Punctures from foot traffic or tools
- Breaches around outlets and penetrations
- Waterproofing to test before it’s covered
If yours is one of the older homes in the streets near Christ Church Ware, the flat roofs on later extensions tend to wear out long before the main roof.
