Electronic leak detection for homes and businesses in Knightwood
Our ELD testing covers flat roofs in Knightwood and the rest of London and South East England. A visit usually takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. Every roof is quoted on its size and build-up. You get a report with photos. If you’ve noticed waterproofing to test before it’s covered and breaches hidden under paving or planting, we can find out what’s behind it, whatever the roof.
Around a smaller place like Knightwood, flat roofs usually cover extensions, garages and dormers. Even a small flat roof can let a good many water into the room below. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Useful tips for Knightwood property owners
A survey works best with a little help from you, before and after. Tips:
- Avoid repeated repairs without finding the cause
- Have roof specifications to hand
- Get leaks traced quickly
- Use boards when working on the roof
Wet insulation may need attention after a leak. That’s something to discuss with your roofer and other checks can help judge it.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.
Local flat roofs in Knightwood
Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With South Stoneham House about 3.7 miles south, Knightwood sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Take a building like Knightwood Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Chandlers Ford station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Knightwood is about 1 mile west of Chandler's Ford, in Hampshire. We provide electronic leak detection for homeowners, landlords and businesses in Knightwood and nearby. Knightwood is one of the places in Hampshire we cover.

Prices for electronic leak detection in Knightwood
To price your survey, we check:
- How many separate roofs there are, like extensions, dormers and garages
- The type of building, from a house to a block or an office
- How complicated the roof is, with its valleys, chimneys and parapets
- The use of thermal imaging or a drone
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

Knightwood: your questions answered
Is Knightwood in the area you cover?
Yes, Knightwood is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Do you cover smaller places like Knightwood?
Yes, Knightwood is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Which days do you carry out surveys?
Surveys run seven days a week. To arrange a date, phone 07833 053749 or use the contact form.
What’s in the survey report?
It sets out what we found, why it matters and what we recommend, backed by photographs. Anything we couldn’t see safely is noted too.
Will you photograph what you find?
Yes. We photograph the roof as we go, and they go into the written report.
What’s the best way to book?
Simply call 07833 053749 or send us an email with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.

Landlord and commercial surveys in Knightwood
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
What we’re asked to look at in Knightwood
New membranes can have defects from installation. ELD on a new roof can show holes before they cause leaks.
We’re often asked to look at:
- Breaches around outlets and penetrations
- Patched roofs that still leak
- Water coming in under a flat roof
- Failed seams and laps
If your home is one of the older ones in the streets near St Francis, flat-roofed rear additions and dormers added over the years are worth checking.
Before you book any roof surveyor
- What follow-up you get after the report
- What’s outside the scope of the survey
- What the report includes, and whether it has photographs
- Whether VAT is in the quoted price
How the survey works
After the inspection, everything we found is written up as a photo-illustrated written report, emailed to you. On timing, it usually takes a length of time set by the roof’s area and construction, which we set out in the quote. Parking around Knightwood is normally easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- We start by finding out what the roof is made of and where it leaks.
- The roof is assessed to see if electronic testing will work on it.
- The method depends on the membrane and what sits above and below it.
- The roof is tested and any breaches are located.
- The breaches are recorded with photos in a report for your roofer.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Keep pets in another room
- Let us know about parking near the property
