Common questions in Alscot
Do you cover smaller places like Alscot?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
Is my home in Alscot listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can you test a green or ballasted roof?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We talk this through first.
What do I do with the report?
You’ll receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Which days do you carry out surveys?
We carry out surveys on weekdays, Saturdays and Sundays. To find a day that suits you, phone 07833 053749 or send us an email.
How do I book a survey in Alscot?
To arrange a survey, phone 07833 053749 or drop us an email and let us know the address and what you want to find out. We’ll confirm the price and agree a day with you.
Electronic leak detection in Alscot
There are different ELD methods. Low-voltage testing is usually done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof and we explain which we’ll use. We’ll say if your roof does not suit either method at the outset. We survey flat roof membranes, single-ply roofs and liquid-applied waterproofing, and the problems we’re asked to look at most are damp inside with no sign on the roof and waterproofing to test before it’s covered.
Flat roofs on exposed homes in small places like Alscot take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
Nothing in the report is left vague: if work is needed, the report says so clearly, along with how urgent it is.

What we do, step by step
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take as long as needed for the size of the roof and how it’s built, which we set out in the quote. Rural addresses near Alscot can be hard to find from a postcode alone, 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.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- Check pets are kept safely away
- Have any questions written down, so nothing gets missed
- If it is not your property yet, arrange access through the agent
Booking a survey
A quick phone call is normally the easiest start: call 07833 053749 or drop us an email, and we will ask about the building and what you need. You’ll have a price before anything is arranged.

What this survey can’t tell you
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- The extent of water in the insulation
- Repairing the breaches (that’s for your roofer)
- Leaks from walls, copings or rooflights
Not sure which survey suits your roof? You can ring 07833 053749 or use the contact form and we’ll tell you. What our survey covers.
What we check
- Green roofs
- Commercial flat roofs
- Roof terraces and balconies
- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
What affects the cost of electronic leak detection
Not every roof costs the same to survey, for these reasons:
- Extensions, dormers and garages with roofs of their own
- Any need for thermal images or a drone flight
- The roof’s overall size
- Whether it’s a home or a commercial building
For a price for your roof in Alscot, call 07833 053749 or email us and let us know about the roof. The price is agreed before a date is set.
What we need to know
What helps most when you contact us:
- The style of property, from a terrace to a block
- Anything about access we should know
- Pictures from the garden or a window, if you have them
- Where water is showing inside, if it is
Photos help, if you have them. Take them safely from the ground or a window. To get started, phone 07833 053749 or email us.
Roof by roof
Single-ply membranes
Many offices and units have single-ply roofs. Seams and penetrations are typical breach points.
Inverted and paved roofs
Paving and terraces cover the membrane. Suitability depends on the layers.

Electronic leak detection in Alscot: local notes
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your 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, so check with the council. Thatch survives on some older buildings in Buckinghamshire’s villages. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If your home is one of the older ones in the streets near St Teresa's Church, flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Monks Risborough station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Leave it or get it looked at?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Outbuildings and barns around Alscot are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. You’ll know the figure before booking.

What we are asked to look at in Alscot
Work on the roof can damage a membrane. Fixings, equipment and foot traffic can leave small holes.
Look out for signs like these:
- Water coming in under a flat roof
- New membranes needing a check before handover
- Holes left by work on the roof
- Leaks through a covered membrane
Take a building like Princes Risborough Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- Their drone registration, if they fly one
- How they plan to inspect the roof safely
- Whether VAT is added on top
- What they will not be able to tell you
