Electronic leak detection in Grandpont: what you get
We carry out electronic leak detection on flat roofs in Grandpont and across London and South East England. Testing typically takes a time that depends on the size of the roof and how it’s built, which we set out in the quote. Every roof is quoted on its size and build-up. The results come in a written report with photos. If you’ve noticed failed seams and laps and a flat roof leak that can’t be traced, a survey will tell you what’s going on.
Flat roofs in smaller places like Grandpont can be more exposed, particularly where nothing shelters them, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You will see the good as well as the bad.

Different roofs, different checks
EPDM rubber roofs
Whether an EPDM roof can be tested depends on the membrane and build-up. We check this first.
Single-ply membranes
Single-ply membranes are common on commercial and newer roofs. Laps and fixings are where holes frequently appear.

For landlords and managing agents
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, phone 07833 053749 or send us an email.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant in advance.
Your questions about electronic leak detection in Grandpont
Will you come out to Grandpont?
Yes, Grandpont is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Does a conservation area affect roof work in Grandpont?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
How do I arrange electronic leak detection in Grandpont?
To book, call 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 agree a day with you.
Can you test a green or ballasted roof?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We’ll discuss it before we quote.
Can you survey in bad weather?
A survey can typically 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 will arrange another day with you.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks. Just call 07833 053749 or email us for a quote.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
Useful tips for Grandpont property owners
A survey works best with a little help from you, before and after. Tips:
- Act on new leaks promptly
- Make sure trades protect the waterproofing
- Record dates and spots where water appears
- Avoid repeated repairs without finding the cause
File the report with your roof paperwork. It shows the condition of the membrane on that date.
Ask trades working on the roof to protect the membrane when fitting equipment. Have the roof looked at after other work.
Local flat roofs in Grandpont
About 1 mile north-east lies Holywell Manor, a reminder of how long the area around Grandpont has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you live in an older home near St Matthew's, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. Landlords with a home close to Oxford station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you run a business near Westgate Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Grandpont is about 1 mile west of Oxford, in Oxfordshire. Whether the building in Grandpont is a house, a flat or a commercial unit, the roof can be surveyed. Across Oxfordshire, we cover Grandpont.
Electronic leak detection in OX1 and OX2 are booked the same way as anywhere else. If you need electronic leak detection at a property on New Road, Shoe Lane and Osney Lane or anywhere close by, we can help. Grandpont is on the A420, so it’s easy for us to get to. If you’re just outside Grandpont, we cover St. Ebbes (1 mile north), New Hinksey (1 mile south-east), Osney (1 mile north-west), St John Street area (1 mile north) and South Hinksey (1 mile south). We also work in nearby towns like Didcot (9 miles south), Bicester (12 miles north-east), Abingdon-on-Thames (5 miles south), Witney (10 miles west), Carterton (14 miles west) and Thame (12 miles east).
Local landmarks in Grandpont
Typical jobs here are in homes near Raleigh Park, Oxford and Cherwell Valley College and Marlborough House. Nearby too are Greyfriars Catholic School (1.6 miles east) and Radcliffe Camera (0.7 miles north-east). Grandpont’s nearest station is Oxford station, about 0.7 miles north-west. Nearby you’ll also find Radcliffe Infirmary (1.1 miles north) and Westgate Shopping Centre (under half a mile north). Green spaces nearby include Hook Meadow and The Trap Grounds and Harcourt Hill.
What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
What affects the cost of electronic leak detection
Prices always include VAT. What changes the price is:
- The number of roofs, including extensions and garages
- The type of building, from a house to a block or an office
- The height of the building and how the roof can be seen safely
- How complicated the roof is, with its valleys, chimneys and parapets
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
What to tell us when you get in touch
You do not need to know any roofing terms. Just let us know:
- Any deadline, such as an exchange date
- Pictures of the roof from a safe spot, if you have them
- Anything about access we should know
- Any marks or damp showing indoors
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or email us when you’re ready.
How the survey works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. A visit to Grandpont is planned like any other: the time, the access and where to park are agreed in advance. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- First, you tell us about the roof build-up and where water is showing.
- 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.
- 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.
Preparing for the visit
- Move anything stored under the loft hatch
- Dig out any old roof reports or invoices
- Leave side gates unlocked
Booking a survey
A quick phone call is usually the easiest start: ring 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
