Electronic leak detection in Toothill: 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 check a new membrane before handover. 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. Typical surveys look at waterproofing to test before it’s covered and repairs that haven’t stopped the leak, on commercial flat roofs, flat roof membranes and roof terraces and balconies.
Somewhere as small as Toothill, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
The report records the flat roof membrane as we found it on the day. It is useful right away, and a good reference for later, for instance when you want to check whether anything has changed.

Useful tips for Toothill property owners
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Share any drawings of the roof
- Check new waterproofing before handover
- Keep outlets clear of debris
- Don’t keep patching the same spot
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Ask trades working on the roof to protect the membrane when fitting equipment. Check the roof after they’ve finished.
Different roofs, different checks
Inverted and paved roofs
Inverted roofs have the insulation on top of the waterproofing and that changes how testing works.
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
What affects the cost of electronic leak detection
The price reflects the time and kit the roof needs. That comes down to:
- The number of roofs, including extensions and garages
- Height and safe access
- Any need for thermal images or a drone flight
- The type of building, from a house to a block or an office
To find out what your survey will cost, phone 07833 053749 or use the contact form and let us know about the roof. The price is agreed before a date is set.

Toothill questions
Will you come out to Toothill?
Yes, smaller places are covered as well as towns. Our area covers London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
How do I find out if my home in Toothill is listed?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Will you fly a drone over my roof?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, so wherever there is a hole, it passes through. That lets us find breaches that are too small to see.
Can every flat roof be tested?
Not every roof is suitable. Certain membranes are conductive and some roofs lack the layer the test needs. We’ll tell you if yours is not suitable at the start.
Will you go up on the roof?
Not unless it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Why act early in Toothill
Repeated call-outs for the same leak add up. A clear record of where the breaches are helps break that cycle. For an older or listed building in a place like Toothill, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

How it works
We work from the outside in: outside views come first, then the loft space if there’s safe access. In total, it takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Toothill, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photos shows where each breach is.
Preparing for the visit
- Make a note of anything you’d like us to look at
- Clear the way to the loft hatch
- Let us know about parking near the property
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.
Advice
Local flat roofs in Toothill
Toothill is within about 4 miles of the coast, where sea air brings more salt and stronger wind than inland. Wind can catch loose edges and trims on a flat roof, and salt air is hard on metal trims, flashings and fixings. Historic houses such as South Stoneham House, about 4.3 miles south-east, show how far back building in the area around Toothill goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
If you own a rental within reach of Romsey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you look after a building such as The Mountbatten School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Toothill is about 2 miles south of Romsey, in Hampshire. Whether the building in Toothill is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Across Hampshire, we cover Toothill and the places around it.

Do you need electronic leak detection in Toothill?
Joints and laps in a membrane can fail over time. Small openings at laps can leak long before anyone notices.
Problems we come across often include:
- Damage from equipment installers
- Stains far from any visible defect
- Breaches around outlets and penetrations
- Gaps at membrane joints
If your home is one of the older ones in the streets near Church of St John, the flat roofs on later extensions tend to wear out long before the main roof.
