How the survey changes by roof type
Single-ply membranes
Some single-ply membranes suit electronic testing well but it depends on the product and layers.
Inverted and paved roofs
If the build-up rules out ELD, we will say so.
Electronic leak detection in Old Alresford
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. The results come in a report with photos. If you’ve noticed gaps at membrane joints and holes around roof penetrations, we can find out what’s behind it, whatever the roof.
Somewhere as small as Old Alresford, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: 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 as you book.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What affects the price in Old Alresford
A few things affect what a survey costs:
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
- House, block, shop or office
- The size of the roof
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
These details help when you contact us:
- Dates you’re working to, such as exchange
- Any photos you have, taken from the ground or a window
- Any stains, drips or damp patches you’ve seen indoors
- The type of building and roof, such as pitched or flat
To arrange a survey, phone 07833 053749 or use the contact form with the address and what you’d like to know about the roof. We will confirm the price before booking.
When to book a survey in Old Alresford
New membranes can have defects from installation. Testing before the roof is covered or handed over helps find them.
We’re frequently asked to look at:
- Punctures from foot traffic or tools
- Failed seams and laps
- A flat roof leak that can’t be traced
- Waterproofing to test before it’s covered
For site and facilities teams at buildings such as Perins School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before you book
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- Whether the loft space is looked at, where there is one
- What they won’t be able to tell you
- Whether they hold professional indemnity and public liability insurance
Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Limit access to the roof
- Act on new leaks promptly
- Keep outlets clear of debris
- Let us know about the membrane and build-up if you know it
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Make sure contractors protect the waterproofing when they work up there. Check the roof after they’ve finished.
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
FAQs for Old Alresford
Is Old Alresford within the area you cover?
Yes. Old Alresford is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Do you carry out roof surveys in Old Alresford?
Yes. We cover the whole of London and South East England, and Old Alresford is part of that. You can call 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.
What happens next?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does the weather affect the survey?
It depends on the weather and the survey. In strong wind or heavy rain, a drone cannot fly and access may not be safe, so we’d move the date with you.
Is this an asbestos survey?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you need to get into the loft?
Where it’s relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
How the survey works
We work from the outside in: outside views come first, then the loft space if there’s safe access. All told, expect more time on a big roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Old Alresford often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we can’t see is noted.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- A report with photographs shows where each breach is.
Before we arrive
- Move anything stored under the loft hatch
- Buyers: confirm access with the estate agent or seller
- Point out any leaks or damp patches
How to book
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or send us an email whenever suits you.
