Electronic leak detection for Sherborne St John homes and businesses
Flat and commercial roofs around Sherborne St John
With The Vyne about 1.2 miles north-east, Sherborne St John sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Thatch survives on some older buildings in Hampshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark such as Church of St. Andrew, the flat roofs on later extensions tend to wear out long before the main roof. Shop and office owners around The Malls may find that a flat roof over a business is out of sight and out of mind until it leaks.

Electronic leak detection for homes and businesses in Sherborne St John
A leak in a flat roof often shows up a long way from where the water gets in. So the stain inside rarely sits under the hole. ELD tests the waterproofing directly, to find where it has been breached. It’s testing only and leave the repair to your roofer. On suitable roofs, it replaces guesswork with a located breach. We then send you the results in a written report. If you’ve noticed stains far from any visible defect and breaches hidden under paving or planting, a survey will tell you what’s going on, on single-ply roofs, roof terraces and balconies and green roofs alike.
Older buildings in small places like Sherborne St John 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. 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, whichever applies.

What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too.

- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.

Sherborne St John: your questions answered
Does a conservation area affect roof work in Sherborne St John?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out roof surveys in Sherborne St John?
We do. The survey and report are the same in Sherborne St John as anywhere else.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We will give you an idea when we quote.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed.
Can you test a green or ballasted roof?
Sometimes. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Can you survey in bad weather?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we’ll arrange another day with you.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years, and 98% of customers are satisfied.
What we’re asked to look at in Sherborne St John
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Most people get in touch when they’ve noticed one of these:
- Failed seams and laps
- Leaks through a flat roof with no obvious cause
- Damage from equipment installers
- Stains far from any visible defect
If you let a flat or house near Basingstoke station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before you book anyone
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Is VAT included in the price?
- Will the report include photos?
- Whether the loft is part of the inspection
How the survey changes by roof type
Green and ballasted roofs
Testing before planting or ballast goes on is simpler.
Liquid-applied waterproofing
What lies under a liquid coating decides if ELD will work.
Tips that help
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Tell us about the membrane and build-up if you know it
- Avoid repeated repairs without finding the cause
- Record dates and spots where water appears
- Use boards when working on the roof
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. It’s easier to find holes before more layers are added.
How we price electronic leak detection
When we price a survey, we consider:
- The number of roofs, including extensions and garages
- Whether it is a home or a commercial building
- The shape of the roof and its details
- The roof’s overall size
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Helping us price your survey
What helps most when you contact us:
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
- How the loft is reached, if there is one
- Any marks or damp showing indoors
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us with the address and the days you’d prefer.
