Electronic leak detection for homes and businesses in Langrish
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Tell us about your roof to find out more. We’re often asked to look into stains far from any visible defect and a flat roof leak that can’t be traced, across roof terraces and balconies, liquid-applied waterproofing and green roofs.
Older buildings in small places like Langrish may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
The report records the flat roof membrane as we found it on the day. It’s useful right away, and a good reference for later, like when you want to compare after future work.

Honest limits
Some things cannot be seen without opening up the roof, and that sets some limits:
- Leaks from plumbing or windows
- Sections we cannot safely access
- Repairing the breaches (that is for your roofer)

What this survey covers
- Liquid-applied waterproofing
- Roof terraces and balconies
- Commercial flat roofs
- Flat roof membranes
- Single-ply roofs
- Green roofs
What we do, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey typically takes more time on a big roof than a small one, with the construction of the roof playing a part too. Rural addresses near Langrish can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Dig out any old roof reports or invoices
- Mention any parking restrictions on your street

When to book a survey in Langrish
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
A survey can pick up problems such as:
- Failed seams and laps
- Holes around roof penetrations
- Water coming in under a flat roof
- Stains far from any visible defect
If you look after a building like Langrish Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book any roof surveyor
- Whether you get a written report with photos
- Whether VAT is in the quoted price
- How long the report takes to arrive
- How they plan to inspect the roof safely
Prices for electronic leak detection in Langrish
We confirm the price for the job before you book. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- Commercial roofs and larger buildings
- How big the roof is
- Any need for thermal images or a drone flight
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Getting in touch
There’s no need for technical words. Just tell us:
- Any deadline, like an exchange date
- What’s prompted the survey
- Anything about access we should know
- The type of building and roof, such as pitched or flat
A quick phone call is normally the easiest start: call 07833 053749 or drop us an email. The price is agreed before a date is set.
Useful tips for Langrish property owners
Most of what helps is simple and safe from ground level. Our suggestions:
- Keep outlets clear of debris
- Check new waterproofing before handover
- Do not keep patching the same spot
- Check trades protect the waterproofing
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
Why act early in Langrish
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
To find out what your survey will cost, ring 07833 053749 or drop us an email and let us know about the roof. We’ll confirm the figure before booking.

Flat and commercial roofs around Langrish
A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
For an older house near a landmark such as Church of St John the Evangelist, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Petersfield station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Common questions in Langrish
Is Langrish within the area you cover?
Yes, Langrish is on our map. A small place gets exactly the same survey as a big one.
Does a conservation area affect roof work in Langrish?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Will you go up on the roof?
Only if it’s safe. We look at everything that can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. Anything we cannot see is noted in the report.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather isn’t right.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. We will talk about access as you book.
What’s the best way to book?
To book, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
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.
